Question for anyone with a watercooled 2080 currently.

So my current setup:
Gigabyte Aorus master z390 mobo
Corsair vengenace 3200mhz 2x16gb
i9 9900k - overclocked to 4.8ghz/1.35v
EVGA 2080 hybrid (not Ti; water cooled AIO pre-installed on the card with air cooling for other components I think?) - overclocked to 1965mhz and 7kmhz on the memory via afterburner/oc scanner
Lian li dynamic 011 case

So I want to get away from the AIO, at least on my CPU, and build a loop. I am deciding whether or not I want to incorporate the 2080 into the loop - the AIO that came with the card actually does a hell of a job cooling it. Max temp in benchmarks (heaven, timespy) and gaming have not exceeded 63C in a room that can be as much as 25-26C ambient in the afternoon.

I have never done a custom loop, so I'm considering just doing the CPU to get my feet wet and maybe adding in the GPU later on, but will I get much of a performance boost in temps with the GPU on the loop? Should I just leave the card as-is, since I'm not really seeing any thermal issues with the AIO?

The GPU idles at about 36C and gets up to about 55C while gaming on a 1440p ultrawide; the CPU idles at about 45C, but at 60C under light load and steady at about 70C while gaming. Aida64 pushed it to 78C after a half hour.

Have you considered the EK MLC Phoenix system? I've found it works great and is significantly less loving around than a custom loop.

I'm considering a lot of stuff - will take a look at this as well. I've built almost this entire build out of open-box and ebay stuff to keep it relatively affordable while not sacrificing much performance, and I may be able to get an EKWB combo pump/res/rad/3 fans/fittings for $100 or so this week so kinda starting there.

Is the Phoenix system much different then just upgrading from a 240mm AIO to a 360mm - beyond the option to add in stuff to the loop later on?

It's pretty much that, but affords you somewhat easier expandability/upgradability over time by linking everything together with QDCs.

You could of course do that with a custom loop, but when I costed up doing a custom loop vs the EK MLC modules it was cheaper and less hassle. If you're looking to create something pretty however, the MLC is probably a non-starter.

Hmm. Question. How do cans and radiators actually mount to the case? Could you mount a 240mm rad to the inside front of a fractal meshify mini c and mount 140mm fans to the outside of the front (inside the bezel) and have that all work correctly? You'd lose some airflow through the rad, obviously. But the mounting is the bigger question for me.

Yes, but you'll probably need screws with longer, less aggressive threads. Using the old fashioned fan screws that chew through metal are a big no no when it comes to radiators imo.

E: I did this years ago because space inside the chassis was at a premium and I was doing a push/pull setup.

Does anyone make a pump/block combo that doesn't need a reservoir like an AIO but probably better than any AIO? I want to do custom tubing in a SFF but instead of cutting up an AIO I thought it would be better to just go custom, no?

EKWB canned their MLC Phoenix line, which has the pump/res integrated into the radiator and allows for blocks to be added modularly through quick disconnects. I mention it only because all the components are being sold at like 40% off on EK's web store.

I actually bought the 360 rad, CPU block and a GPU block when it was at full retail price and it's really good gear if you're not doing a build for aesthetics.

I've got a real job after years of being a poor student and figured I'd celebrate with my first completely new build in more than a decade. I've never done liquid cooling before. It looks fun to try but after a couple of hours of research this could get mindbogglingly expensive.

Any general advice on where to start, what to avoid, rules of thumb for figuring out how many fans and radiators I need?

Depends on what your goals are, are you looking for maximum performance or a much quieter experience? I'm a big fan of a 360+240mm rad setup for a single GPU and high end CPU PC because you have the flexibility to push for maximum overclocks or run everything bone stock at near silence, but that can easily be overkill for a lot of rigs.

Trip Report Time.

WC'ed my desktop over the weekend. Long time coming project. Had years ago sourced a bunch of parts to do a SFF WC in a Ncase M1 and after stripping it down, getting blocks on, realized it would be pretty difficult. So I shelved it. Fast forward, my current desktop uses a NZXT H700, so more space. Stripped off a Noctua D-15 and a reference design cooler (sorta) off a 2080 ti (EVGA Black). Main driver was getting the GPU's noise under control.

Had to purchase some additional things. Went with a new CPU block for nickel plating (using liquid metal between the cpu and it), new GPU (so new block), bigger rads because have the space, some fans, additional tubing, and mounting bracket for pump assembly. Performance PCs had the stuff I needed, but man their website sucks.

Monsoon's soft tube compression fittings suck with EK's ZMT tubing (16/10mm). Use some dish soap the unthreaded side of the compression piece otherwise you'll fight with the tube friction in addition to pushing the compression piece down and trying to get on the threads of the barb. Additionally, Bitspower's D5 MOD top pump housing, it kinda sucks for how the inlet and outlet ports are laid out. One side has an in and out, but they are too close if you use any other than the narrowest fittings. Ended up using the outlet and a temp probe for the inlet port on that side with a the inlet on the opposite with just barely enough space between the 90 degree fitting and the mounting bracket. Mounted the pump/reservoir assembly to the front radiator.

Used Watercool's HEATKILLER blocks for the CPU and GPU, delidded direct die 9900kf and a reference model 2080 ti. Two Hardware Labs 360GTS radiators. Arctic P12 PWM PST fans. Waiting on a Noctua 120x15 fan for the back of the case for exhaust as a 25mm doesn't work with the top mount rads ports.

Loop under sustain load stabilizes out at 44 degrees C (about 15 degrees over ambient) with the CPU staying around 55 and the gpu around 55 as well. The pump speed and fan speeds are kept lowish for noise purposes. Both the CPU and GPU are overclocked, the CPU at 5ghz and no AVX offset, and the GPU unfortunately is a non-A part so max power limit is 124%.

Fun times, one hand still hurts from the drat fittings.

An easy way around those GPU power limits if you've got that kind of watercooling is to flash a power delimited or voltage unlocked BIOS, especially since you have a reference card. I did it with my 980 Ti and later my 1080 Ti and got much better overclocks once heat is no longer a concern. It's especially easy with Pascal onwards as Afterburner will automatically fine tune the voltage, power and clocks. Overclock.net have an excellent thread filled with information for this exact purpose: https://www.overclock.net/forum/69-nvidia/1706276-official-nvidia-rtx-2080-ti-owner-s-club.html

I did that yesterday. My card despite being a reference board it has a non A chip, so the highest power limit bios available is the one from Palit at 124%, stock one was 112%. It's a shame as the board seems decently strong: the memory is Samsung and I'm holding a 1 GHz OC on it for 16 GHz and the GPU itself can take a +180 core OC without a sweat. It just hits that 124% very easily in the 2040-2085 range. Have tried a static bump as well as a custom voltage/boost curve. Oh well, it's good enough. No sense trying to chase down say a EVGA XC or other similar card (300A chip based reference) for like 1% more frames.

Thanks for the detailed reply.

Well. I just put together my first loop and I have a horror story for the thread to show for it. Ryzen 3700x and a 2080 TI FE went into it. Not a single leak anywhere, setting up the water blocks and the actual loop went perfectly. The pump works, everything connected right, pc booted up to desktop on the first try.

... Until I ran Heaven and my gpu rocketed to 80c and then crashed after 30 seconds of a blistering fast 10 fps. Thought it may have been a fluke but no it was not. Turns out I used the wrong size screws to screw in the waterblock (they were 5 mm, I should have used 4mm, OOPSIE :rolleyes:) and so it had poor contact with the copper.

So I undid everything, drained the gpu section of the loop, and took it apart to redo it with the right ones. Except, see pic included. The standoffs came off of the block because of the too-long screws in the PCB. Thus, pliers and gruntwork and a bit of weeping ensued. Lo and behold, I got everything assembled with the correct screws this time and... Nothing. No signal.

The gpu is seemingly just stone dead. PC boots to desktop still and the loop and cpu's temps are all perfect. An older gpu works fine in the mobo so it's gotta be the part itself. I have no idea how but I killed 1200 dollars worth of gpu. So let this be a lesson to you: learn to differentiate extremely tiny screws from one another because it may fry your graphics card.

Edit: the good news is the gpu is brand new so I may be able to RMA it if I put the air cooler back on and look away while whistling like I'm not incredibly guilty. For all I know it was already kinda busted and I just broke the camel's back!

loving ouch dude.

Though I didn't even realise EK provided two different lengths of screws. Must be dumb luck I haven't done the same in past.

I’ve had an old EKWB AIO sitting in my closet for a few years which I bought on a whim. It has been sitting in the box since 2016 or so, and I’ve only taken it out a few times to look at it. I finally have a case with some room for a big radiator, so I figured that I could finally install this AIO.

Is there any risk to running a component that is this old, even though it’s completely unused? Is there anything I can or should do to test for functionality? It’s definitely not under warranty any more, and is past EOL status.

If it's the Phoenix line you should be able to drain and refill it with a hex key on the radiator. Even though I'm 90% certain the fluid is the EK Cryo clear stuff, I'd absolutely do it for peace of mind.

Personally I would, just because even the clear stuff will degrade over time, even if it isn't being thermally cycled frequently. I have a bottle of it in a cupboard somewhere and it has a suggested shelf life printed on the bottle.

Yeah the Lian Li looked OK. I want to try and use a distribution block with integrated pump to reduce tubing bends and EK makes one for that case. My D5 is like 11 years old so it's probably time for a replacement.

Thanks for the suggestion.

FYI if you do go down that distro plate route with the O11-D, you *might* just fit a 360 on the roof/floor and you'll only be able to fit a slim 360 rad in the rear chamber. I ended up going for a slim 360 and regular 240.

Also, if you're using an EK AMD CPU block, the in/out ports are horizontally level and the CPU in/out ports on the distro plate are vertically level and it's infuriating just how loving dumb a design oversight that is.

A random musing, but years ago there was a company called Monsoon that made rather ornate fittings that came with a tool that you inserted into the collar of the compression fittings to twist them onto the barb.

Shame they presumably went bust because it was a brilliant idea and I can't believe EK haven't ripped it off considering they had the foresight to make the inner part of their barbs hexagonal so you can tighten them up with a hex key.

My only non-unicorn vomit critique is that I think matte black tubing would be a cleaner look. I always feel that the translucent soft tubing looks 'cheap.'

Ha! I quite like the all white static LEDs so I may finally decide upon that. The PSU in the back of the case in its own compartment at the bottom. The hardware monitor is just a cheap no-name touchscreen 7" IPS LCD for Raspberry Pis I got off Amazon and its running SensorPanel through AIDA64 connected to a free USB 2.0 header on the motherboard for power and HDMI into the GPU. It's mounted on standoffs where the case is designed to have a mini-ITX second system with a flat brace to line up one of the standoffs with the top right mounting hole on the screen.

I know he's marmite, but I basically ripped the idea from a jayztwocents video on youtube. :)

I have previously used EK's ZMT, the only problem I had was that the ID/OD tubing I could get my hands on at the time was too thick to easily route in some of the tighter spots like between the two front radiators.

I had that issue in my Ncase, but the solution ended up being just not attempting to take the shortest run in each situation. I have three runs of 16/10 running parallel over the top of the GPU for instance. My tightest run was from the GPU to my bottom radiator, which is basically a 90 degree turn with a 2 inch radius I think? I'm worried slightly about it being a lot of sideways pressure on the fittings potentially causing a leak somewhere down the line, but the alternative is even more Rube Goldberg-style tubing runs.

Optimal flowpath is keeping tubing runs as short and straight as possible, loop order really doesn't matter in any practical sense as the loop will eventually equalise as heat is spread around.

2x 280s will be enough. If the top mounted radiator is exhausting air then pull is probably fine as you're working with physics, i.e. heat rises. Your main consideration should be good static pressure fans, beyond that push vs pull is really an aesthetic choice.

As long as you have a decent enough pump (D5) I would argue reservoir mounting height doesn't matter. A D5 has enough head pressure and flow to push air out of a loop without issue. Definitely give thought to putting a drain port/T line at the lowest point of your loop though, it'll make your life so much easier when it comes to drain it for maintenance or to add/remove components.

For dyes, I'd avoid anything solid/pastel coloured and double avoid any of that weird flow effect crap. EK's don't seem to gunk up blocks, but they definitely stain them and tubes. The more 'watery' coloured fluids don't seem to be quite as bad, but expect discoloration over time.

This is the PCIe 4.0 riser I have and it works absolutely fine, not a single issue with it. I've seen people having problems with PCIe 3.0 risers on PCIe 4.0 boards, but issues with them seem to be completely random.

The above is based on my experience and I'm sure there are other posters with vastly more experience than me!

I ran a Google translate on their FAQs for it, apparently you can use soft tubing provided that the OD of the tubing is at least 1.5x the ID. So 16/10 would theoretically be fine but 13/10 would not.

Second question a lot of people are saying negative things about nickel in their loop. If I buy the Quantum Magnitude sTRX4 water block, it has nickel in it, and it's cheaper than the copper alternative that they sell. I'm pretty sure everything else is copper should I get copper for the water block too?

I was planning to use CryoFuel Clear premix.

I was under the impression that EK's nickel blocks were the same as the copper ones, just plated with nickel for the aesthetic? I doubt you'd notice any meaningful performance difference and given that nickel and copper don't react with one another, galvanic corrosion shouldn't be a concern either.

There is the possibility that the nickel will wear over time and reveal the copper underneath but it's never an issue I've had running clear premixes or straight DI water.

That's what I've heard. Horror stories about corrosion, it's completely hidden inside the block so I have no idea why ek would nickel plate it other than for product shots of the thing disassembled. Which makes me suspicious about the entire company.

So it won't likely corrode and deposit nickel flakes in my radiator and pump?

I can honestly say I've never had it happen on any of my EK gear throughout the years and I've always gone nickel because I like the silver shine. Excluding any manufacturing defects, my belief is that as long as you use high quality components from reputable brands and use DI + additives as directed or a quality premix you shouldn't have any issues.

My current loop is just past 12-months since I last drained and refilled and 18-months in total since I put it together. All EK nickel blocks with CryoFuel clear premix and still all fine. I think my PB was something like three years between a fill and drain and that was only because the pump I bought developed a rattly bearing and I had to replace it, learning the hard way why you always fit a drain port. That was straight DI with a silver kill coil in the reservoir and no gunk or corrosion when I took it apart.

e: In the interest of balance, I only really ever use EK stuff wherever possible because I really like their style and they're made (fairly) locally to me in Europe. Some of their stuff, e.g. radiators, really aren't as efficient as some of their competitors (I seem to remember their slim rads are particularly bad) but I take a likely misplaced sense of comfort that if I use everything from one brand it has all at least been designed and tested to work together in harmony.

That's reassuring to hear.

My suspicion is they have three reasons to add nickel plating, 1. it looks good. 2. it corrodes after a year so people have to replace them. 3. the corrosion damages the entire loop so you have to replace everything else too. This is heightened when they are nickel plating things people can't even see. On the ek webshop page there's all these warnings about additives you need in the fluid because of the nickel. It makes me nervous like well then why did you put it there?

But if you say it's not a big deal and you haven't had any problems then maybe my usually helpful general skepticism about everything is misplaced here.

It's sensible to be skeptical, but given that water cooling is a small niche within an already tiny niche of the home computer market, I'd like to think any company manufacturing water cooling components with shady ulterior motives would be out of business very quickly. EK's reasoning for nickel plating their parts is that it's normal for bare copper to oxidise over time, which ends up looking pretty awful if you've got plexi blocks. The nickel plating protects against that.

I'm hesitating a purchase for 3 days now all because this one 80 cent item in my cart is out of stock https://www.ekwb.com/shop/ek-hdc-fitting-14mm-o-ring-6pcs I probably don't need spare o-rings for my first build right?

I made a real hash job when I did hardline tubing and didn't need any spare o-rings. Just make sure you sufficiently deburr your tubes before fitting them.

I would give my opinion on the anti-EKWB comments but I feel like I'm solidly out there as a big fan of their products and my opinion should be treated with equal weight. As SpartanIvy said, their stuff just works. Is it any more performant than their main competitors given the higher price? Debatable, I'd even argue not justifiably so on that metric alone. Does their stuff have a far more premium feel? I definitely think so. The worst part of the internet is every dickhead and their dog can make comments and I see a minority of comments moaning about negative user experiences with EKWB and far more being pissy about the price of it, which I kind of understand for prospective customers outside of Europe where they probably eat a bunch of taxes on them.

That being said I don't post on motoring forums making GBS threads on a recall Bentley issued for a car I can't afford. :shrug:

Plug the pump into the CPU fan header? I would imagine without something plugged into that header the system either won't POST or BIOS will constantly moan at you.

For short, bursty loads it will be quieter and just as efficient to have the pump speed increase as you'll be passing a greater volume of coolant over heat-generating components, then you can set the fans to spin up to a higher RPM once you hit a certain temperature that it will usually only reach under sustained loads. For example, up to 70'c on my 3900X the fans remain at around 650RPM whilst the pump gradually increases in speed, this means that the fans only ever become noticeably audible when there's a heavy sustained load like a video encode or large file export.

Coolant temperature sensors are a good failsafe if you don't have a flow meter, but I wouldn't rely on it for setting fan curves to.

Imo it is complicated, cause

-they dont really have the best blocks and are expensive
-not many radiators to choose from (no good low fpi stuff)
-if you use no rotatable fittings they really dont matter and i dont see the value in a quantum fitting for 8€ a piece

IMO if you are serious about watercooling it is really hard to buy only EK stuff

I was with you until the no true scotsman poo poo at the end. You can take something seriously and not feel compelled to min/max if your needs are straightforward.

No sweat, I do have a box full of those 45 and 90 degree swivel fittings because I'm an absolute sucker for them lol
