They're also just super bad fans independent of their appearance. You probably have enough that it doesn't really matter but it's a strange concession for such a high end build.

I managed to get two EK FC980-TF5 as well as an acetal 3-slot bridge for $6 each and $3 each respectively so I guess I am watercooling my current rig instead of the next which was the plan.

Whats the word on running multiple components in parallel? It would make things a lot cleaner to manage in my small case. I am planning a loop in my P400s. Back 120mm radiator, front 280mm. D5+reservoir in the front behind the 280mm, two GPU blocks and a CPU block with a parallel GPU bridge. I was thinking of having the GPU bridge in parallel with the CPU block and the back radiator so I can connect the loop only to the bottom of the case and not having it running across the top back to the pump.

Pump/res -> GPU -> CPU block -> 120mm radiator -> GPU -> 280mm radiator -> Pump/res

Like this:



But with the back radiator also in parallel.

I love the build Scarecrow, unfortunately they weren't out when you started but it is possible now to have both RGB lighting and high quality fans in one. Phanteks sells RGB fan frames so you can have good RGB with any white bladed fan.

For anyone else buying new fans for loops, avoid the noctua F series fans. They're super outdated and superseded in every way by newer fans in performance/noise/price, hell they weren't even the best when new. The best thing to look at are darkside GT's, NB eLoops, EK Vardars, or Corsair ML series. The ML's aren't the absolute best for performance (that would be the GT's and their cousins), but I love them for their total lack of bearing noise and overall pleasant tone. Phanteks makes super good fans as well, but they are mostly the best in heatsink fans (for tower coolers). This is really not relevant for Scarecrows build as there is enough rad space that it doesn't matter at all. It could probably be run passively for a decent duration due to the sheer heat capacity of that much fluid and passive heat transfer.

Awesome, it really came together. I think some custom cables with combs are the only thing missing. Have you tried running it passively under load? You have so much rad space and huge reservoirs that I imagine it could sustain impressive loads without the fans running at all.

I'm just getting in the final parts for a loop now myself. Nothing aesthetic or performance focused, just for silence. I have a windowless Phanteks P400s that I am stuffing a 280mm and 120mm radiator in. Using plain black looks with a focus on reliability and low maintenance silent computing. The whole thing with EK blocks/fittings/tubing, a DDC pump, and nemesis GTS rads only set me back $380 AUD total for CPU + 2 GPU with full cover blocks. I'll probably run it passive at idle and as low fan speed as possible that keeps the water at safe levels under load.

yeah the plan is to have everything power down to basically off when not needed once I work out how to setup the Aquaero software right, tho the garbage thermaltake fans are currently loving up that plan and im looking at replacing them with EK fans with phantek led covers

I'd recommend trying out the Corsair ML fans. I have two MLs in my computer and they have the nicest acoustics of any fan I've ever used. They don't match up with Vardars for CFM/SPL but they totally lack bearing noise and they sound really smooth and pleasant. I'm going to compare them with my Vardars on the radiator when I get it all built, waiting on a radiator coming in from America (I simply had to have a cross-flow rad for how easy it makes tubing runs). I've got a fancy studio mic that could record the difference.

They've got white blade non-LED ones that you can put frames on easily. I personally stay away from everything thermaltake makes for liquid cooling, due to their propensity to put aluminium flow channels everywhere like loving morons. They've been putting out way more interesting cases recently though.

My first set one of them had the high pitched noise. It was incredibly poo poo and irritating, but the second set I exchanged them for don't have it at all. It was a sound just from the bearing and it seemed due to damage or something faulty. It seems it's a problem that some of them have out of the gate.

I own both and can happily say Corsair ML all day long. They are greyish blades however so they won't be as clearly lit with the frames as the EK fans I think. The MLs just sound so drat pleasant.

I usually use Mwave or Umart because they're both 10 minutes drive away. I've only dealt with Mwave support, they're slow but they always accept returns no hassle in my experience.

I only bought from PCCG because they have fittings that no-one else keeps in warehouse stock and I didn't want to wait for Mwave to ship them from Slovenia. I really wish we had a good big retailer that specialised in water cooling as it's a real pain to get specific fittings.

Gonna cross post this from the GPU thread.

Now I know that there are fan adaptors for graphics cards that let you use the GPU's fan controller with case fans, but does anyone know if LED adaptors exist? All NVIDIA reference GPUs use the same two pin connector for the included LEDs. I want to be able to adapt some 3mm leds to the 2 pin connector so that I can control the LEDs in my waterblocks with NVIDIA's software. Am I mad or is this a thing that just doesn't exist?

What are my options for throwing an AIO on a Vega 64?

The Alphacool NexXxos GPX - AMD RX Vega M01 looks nice, I just pair this up with one of their >120mm radiators? and a hose that fits yeah?

240/360 seems like overkill, but that seems to be required if you really want to keep HBM at 1200mhz

The block you've linked is just a waterblock, I believe their GPX Pro line are the ones with the pumps. If you're going to spend that much I'd wonder if it is worth just going for a proper custom loop. The much probably better option for closed loop is a NZXT G10/12 and any Asetek AIO, should be substantially cheaper and not much worse. Going for a custom loop lets you cool your CPU and gives you much more flexibility for expansion and part selection. Worst case you can go for an EK A240R aluminium kit for around the same cost.

That's a good protip re: angled fittings, thank you. I had noticed that it did look very clean


:eyepop: that's gorgeous dude. How do you have the controller mounted in there? I hadn't considered just putting one in there sideways like that. Looked over at this tower like "welp, no drive bays" and that was that

I'm assuming the outlet from the GPU block on the bottom is going back to the rad/pump? Is it best to run them like that? I was thinking it would look a little cleaner/tighter if I could do them both on the same side

I really like what they did in their guide with the M/M extenders, the 3F splitter, and the ball valve



Can you do custom inserts inside the reservoir? The EK logo is ok but if I could put my own shape in there that'd be fantastic

It's looking like multiple orders/shipments is unavoidable :sigh: Going to have to fit and route everything first to see if I need more/different angled fittings. I'll have to wait till it gets here, but my plan is to run a fill port from the back of the case towards the top that'd have a downward slope into the top of the res. I think I'll be able to run the splitter off the rad and still have enough downward slope on the way to the back panel In a perfect world I might try to put the ball valve on the outside so that I don't have to take the side off at all when I swap fluid.

It's too bad they don't also offer white versions of everything I'm getting in Nickel.

That PrimoChill stuff looks neat, it's too bad the only UV they offer is green. I love warm piss as much as the next guy but that's just not my color for this build. Who else can be trusted for additives? I just had an absurd/dumb thought about a build with sea monkeys in the reservoir. They probably don't like PPG too much lol

I decided to get the Dual D5 instead. Monoblocks seem to benefit more from the added flow, and anecdotally the people I see with the highest clocked vegas are running dual pumps, so maybe it is important in mitigating that tiny little hotspot. Looks like it cycles all of the water in the system almost twice as fast (which is just a few seconds, right?)

E: Hell yes they do it in 5cm increments, I always wondered how people did this so tidy

Yo I know you've already ordered, but you cannot fit a 420 rad in your case. Absolute maximum in the front is a 360. I'd personally recommend going for a 240 in the top as well so you can run your fans a little slower. If you do go for two rads you'll need to get thin ones, the EK thin rads are garbage so you'll want to go for HWLabs GTS radiators. I'd recommend looking at other builds in your case to get an idea, it's most common to go 360+240 with optionally a 120 in the back. I'm unsure if that pump bracket can take the dual pump top as well.

I actually didn't because the purchase got flagged and they locked the card, lucky! For some reason I thought the front was 3x140mm fans, but the max is actually 2 for 140.

Looks like the XE 360 + 240GTS is the move. The GTS is thin enough that the 2nd fan will still fit above the ram, which is awesome. I like the idea of the 120 at the back, would the idea be to route that between the Monoblock and the GPU?

Due to the jet plate, the right port has to be used as input which makes putting the 120 in-between the GPU/CPU a bit clunky. I would go from monoblock output to the rear 120 then up to the 240, but you can try both options once you get all the parts. I'm a big fan of filling every rad space in the case but some people see the extra capacity of a back 120 to be overkill. I think it's merely 'kill.

The XE360 is a great rad, but it is ENORMOUS. Make sure to double check that there is enough space. If you are planning to run at low fan speeds (800RPM~), then the XE360 will actually perform worse than a 360GTS. As the XE360 is quite thick and restrictive, it needs high speed fans to actually push through the whole rad and use it to it's full capacity.



At 1300RPM the XE360 is 18w~ ahead, and by 1850RPM it is 70w~ ahead. If you want a radiator that strikes a much better balance, and can deal with a 60mm, the HWLabs SR-2 is thick but low density. It performs like a GTS at low speeds while having greater headroom. I personally think building a custom loop and running 1500RPM+ fans kinda defeats the point, so I tend to lean towards lower restriction radiators.

What fans are you intending to use? Currently the Corsair ML fans are best in class, and are quite cheap if you buy 2-packs. You do have to make sure to use them with a true PWM signal, as voltage control will physically damage the fan.

I'm currently speccing an upcoming TR2 build, and unlike before, I'm not going to wuss out of watercooling. I'm likely going to stick an 360mm AIO on the CPU, but I'm a bit concerned about the case. I'm considering the NZXT H700 currently, because it looks nice, but it doesn't have direct intakes and exhausts, but everything goes through grids on the side.

Anyone here using that case with a huge AIO? Is that combo OK, or rather not?

I have one with a 360 front, 280 top and 120 read. Temps are quite good, they did a good job having the fan mounts further back from the panel when compared to similar cases. Definitely don't get the "i" model though, the fan controller is total poo poo.

Probably going to re-do my setup later this year. My current loop has been running since about 2013 and it's time for an upgrade and probably a pump replacement.

What do you guys think about EK's monoblocks? VRM cooling definitely sounds worthwhile but I'm wondering if it sacrifices CPU cooling in exchange.

You gain a few degrees in CPU temps just due to the lesser clamping force on the socket, and you can't use delidded CPU's reliably with monoblocks because you change your CPU's Z-height. They look neat as gently caress though and you're probably still gonna have great temps, so it's a cost/performance vs aesthetics thing.

If you do have a delidded CPU, make sure to buy an aftermarket heatspreader that is taller to account for the difference, Bitspower makes a ridiculously tall one that is perfect for this.

For X299/X399 I'd recommend them as you can encounter VRM throttling a lot easier with the huge chips, and if you're going for 5.2+ with 1.4v+ on the 6 or 8 core Coffeelakes then they might be worth considering.

EK slims are the worst copper radiators money can buy, but they do fit the niche of "exactly the size of the fans". If you don't need that, get HWLabs GTS, if you do need that size then get HWLabs LS series (OEM but you can get them from a few places, if you can't they get rebranded as Bitspower thins). HWlabs absolutely dominate the thin radiator scene.

Has anyone announced full coverage blocks for the 3070 yet?

The hydrocopper blocks have typically been very (flow) restrictive and subpar. Their reputation has improved but I still think they're hideous and the flow ports are spaced in a janky way

Preinstalled blocks can be a nice improvement in ease of wareanty depending on where you live, and they save a bit of hassle. It's up to you if that's worth it, you can definitely get a better block and mount it with better TIM if you're happy to do it yourself

You can encounter temperature problems with DDR4 memory running at 4000MHz/1.45v+, especially if you have a water-cooled case filled with radiators and less passive airflow. It'll show up as reduce overclocking headroom and stability. You also see active cooling on higher density 32gb+ modules at 3200 like in servers.

It's slightly less insane than it used to be with less demanding memory, but still lowest priority next to VRM cooling.

If you want to use EK RAM blocks then you can buy their Monarch Modules which will fit standard DDR4 DIMMs and allow you to mount their Monarch X4 block. The Dominator memory they refer to are older sticks with removable fins that allow a flat top to mount the blocks, they're not really a thing anymore so you need to replace the coolers on other memory. An upside of the Monarch Modules is that the nickel ones look really nice and understated even if you don't mount the waterblock on.

The Corsair rads aren't uniquely customised, they're just the L series OEM variants of the HWLABS stealth rads. They're cut down to fit in the exact width of the fans for maximum case compatibility for OEMs. You can get them straight from performance-pcs if you want to cut out the Corsair tax.

Unless I have 3D models of each of these components + my case, I feel like I'm going to end up with a pile of pricey adapters (potentially) and things mis-aligned by a few mm.

There is nothing wrong with it. A popular way of doing hardline a while ago was to use soft tubing in the back for easy maintenance and routing. No need to go to the extra effort for what's out of sight. I recommend it if you're part of the "stuff the rear panel on and forget about it" cable gang

Hi everyone, after many years of custom builds with AIOs, I'm finally jumping into a custom loop because I got an EVGA notify queue pop for one of the 3090s with the hydro copper block preinstalled. Yesterday I transferred my build into a Meshify 2 XL so I'd have more room for the loop and rads.

I'll also be cooling the 9900k in the system. With the case I have, I understand that I can run a thick 420 rad on the top or front but not both at the same time. You can however run a 360 rad on the front and a 420 on the top, which is what I think I'll go for. There's the ability to mount a 280 on the bottom in the PSU shroud but it's really pretty crowded down there and I don't think it's a great option. There's also the 120/140 rear exhaust fan area, obviously a 140 rad isn't going to be life changing but I'm wondering if it's worth just doing anyways since I'll be using soft tubing and it doesn't seem very hard or expensive to add.

Here's a photo of the case now.



Just a stock photo of the case.


So I'm appealing to the thread's expertise. I've always watched some content around water cooling and had a couple friends do it but really a long time ago. Is EKWB still the go-to? I'm in Canada and their local distributors are out of stock on everything and probably won't restock for months. I'm paying 15-20% duty charge on anything imported to Canada from the states.

A summary of my questions

The things I'm cooling:

9900k (overclocked)
3090 XC3 Ultra Hydro Copper (overclocked)

  • Is EKWB still the obvious choice?
  • What difference does reservoir size make? The larger reservoir from ekwb is out of stock on their site.
  • My understanding is it doesn't matter what order you put things in your loops since it all gets to the same temp anyways. Is this correct?
  • If cost isn't an issue does it make sense to use a 140mm rad on that rear exhaust or is there no point with already having a 420 and 360?
  • I assume I'm okay with a single pump/loop given the two large rads?
  • Is it going to be a heat problem if my only case intake is pulling in through a radiator?
  • How are the EK Vardar fans compared to Noctua?

Any input is welcome.

e: I'm thinking I should buy this kit from ekwb which comes with everything needed for a CPU loop and the 360 rad for the front of the case, and add the EK-CoolStream CE 420 rad for the top + the required fittings. Good idea?

That kit comes with enough concentrate to make 1L of coolant. Should that be enough?

e: Playing with mocking up components. Does this make sense?



e2: if anyone wants to draw me a loop feel free:



EK is ok, but their QC is a bit spotty and you pay for the name.

I'm not a fan at all of EK Vardars. I would go for a 480mm+360mm, 120mm fans are preferred here because you can go for Phanteks T30-120 which absolute stomp every other fan even up to the A12x25. I would go for a rear fan as another intake, so 360 front, 480 top (or reverse if that fits better), then a rear intake for fresh air.

Don't buy EK rads unless you can fit the XE. The XE is competitive but the others are terrible, especially the SE thin rad. HWLabs make the best radiators by far, you can go for their GTS series for best all-rounders. They also make the L series which are OEM only but have the exact width of the fans on them, these are useful for cases with limited space for rads. Bits power and Corsair both rebrand slim L series HWLabs rads so you could get those if they're more available.

You might need more than 1L, I have 1.2L in my loop that is 360+280+120, but I have a huge monoblock that holds a lot.

Thanks. I should have mentioned that I'm based in Canada so it's hard to find a lot of this stuff. HWLabs is on our amazon.ca but nothing in 420 seems to be on there.

I filled a cart on EKWB tonight and then was hit with 80 bucks shipping on top of the 20% duty I'd have to pay, which kinda made me hesitate. I wasn't expecting to have to pay what now comes to 800CAD to set up watercooling. Kinda don't know what to do now, my cart is still full so maybe I'll sleep on it. The Canadian distributor is canadacomputers which is one of the least useful businesses in this space.

I really would look at 480 instead of 420, it's more total raddage and 140mm fans kinda suck right now (no 140x25 or T30-140)

I didn't even think of it, but hey, 9900K + Ampere gang. I have two temp sensors, one for ambient and one for coolant and I typically target 5-10c over ambient. You definitely want to tie fan speed to coolant temp because it's the actual dependant variable.

My 3080 sits around 45c in games, but it'll break 50c if I turn up the power limit to 500w and go for 2150MHz core. When I'm mining overnight it sits at a lovely 35c ish

CPU is at 5.1, and I've got DDR4 waterblocks delivered and I'm just waiting on some fittings. It seems insane to watercool ram but I've got very low case airflow and I get consistent temperature instability with my ram when overclocking (3900c14 @ 1.55v, goes unstable like clockwork when the ram hits 50c). 360+280+120 radiators

I keep my D5 at 100%. At the distance I sit from my computer, and with the case sides on, the pump noise isn't audible. Which is strange, because I'll get annoyed if my fans touch 1000rpm

I dunno why I'm so much less sensitive to the pump noise.

Currently I'm using 2xML140 and 4xML120, but I have four T30-120 and two P140 CO on order. The ML fans have really low and soothing bearing noise but it's obvious they aren't the best fan blade design for airflow/RPM

I swapped from an EK DDC to an EK D5 pump, noise is more manageable with the D5 at full speed (I believe full speed isn't as fast as some other D5 though) than the DDC on PWM. DDC is just unpleasant sounding, even at same dB. You get insane pressure out of them though, good if you have a very restrictive loop.

Hey so I posted awhile ago about my build, it's a 9900k and 3090, with two 420mm rads. I've really been waffling on orientation of the fans on the rads, which will be front and top. I've always had my rads exhausting to the outside of the case, but I worry if I do that with this setup I'll have a pretty serious negative pressure/dust issue in the case. Here's the mockup again but with the non-radiator fan locations marked in purple, and to clarify, the basement plate above where the two bottom fans are will be removed anyways for the radiator so there's nothing really blocking them:



So if I set the rads up as exhausts, there are 3 140mm fan locations available for intakes. So I would have like... 6 exhaust fans and 3 intake fans. Even given that the exhaust fans are pushing through radiators, and won't need to be ran very fast due to the amount of radiator I'm running, and I could run the three intake fans pretty high speed without hearing them (Noctua), it just feels like I'll still be negative pressure.

If I set it up so air is being pulled through the rads into the case, I only really have one good exhaust fan option, the rear top one. The two fans in the basement area will not really be getting a lot of hot air and probably wouldn't be great as exhausts. I also don't love the idea of keeping every single component in the case warmer than necessary, especially as I still have two HDDs in there.

What would you do and why?

e: All the fan locations are filtered, even the back 140mm fan has a filter.

Personally, I would go front intake, top exhaust on the radiators, then just gave the rear 140 on intake. The bottom two slots will just mess with the flow, I feel. You'll also run into space issues with the max size rads and a decent PSU trying to fit bottom fans.

I have 360 front intake, 280 top and 120 rear exhaust rads and I have to run the front fans a slightly higher curve to have positive pressure (testing just by feeling airflow over little gaps)
