What's an acceptable water temp anyway. If I have all my fans set to super slow basically silent, my water temps climb up to around 45C. Only reason I ask is I have an acrylic res and would hate for it to decide to start leaking due to the water getting too warm.

I've had it previously argued to me in this thread that you want to avoid high temperatures in your loop to avoid thermal expansion of your coolant and any softening of the plastic that might occur. That was in the context of asking whether you could run two 980 Tis and CPU (~600W) on a single 240mm radiator if I was primarily concerned with running a small case with tight airflow as opposed to just keeping it ice cold. I think people may have been exaggerating the issue somewhat given that the 295X2 runs 500W on a single 120mm radiator, but that was the advice at the time. Thermal expansion probably shouldn't be an issue if you have some airspace in your reservoir.

Thermal expansion of water is pretty negligible (until 100C  ). Some shady Internet calculator says 30C to 70C is 1.2% expansion.

EVGA is apparantly giving people with 980, 980 Ti or Titan Xes in their Hybrid line new shrouds. I think I saw some people talk about those cards here. This seems like a good place to share news with those people. http://www.tomshardware.com/news/evga-hybrid-faceoff-program,30263.html

How many heat pipe failures would be required for the heatsink not to be able to transfer heat over a large heatsink? I see five and six heat pipe heatsinks for GTX 980 Tis and they cool down to like 68-72c. Where as my Galax can hit its adjusted 91c thermal limit in any non-limiting game. For instance Blacklight Retribution limits to 60 FPS and only uses about 30% GPU, but witcher 3 obviously uses 100% which causes thermal limiting. I'm at my wits end with this card. They sorta fixed the fan ramping issues I had with it. I can't return it for a refund, unless my Mastercard gives me extras benefits I don't know about. I've tried repasting it with Arctic ceramic, which didn't help. I need some advice here. Edited for grammar and spelling. SlayVus fucked around with this message at 02:47 on Oct 8, 2015 |

Has anyone noticed an issue with a 980ti, latest Nvidia drivers, and a displayport monitor not waking up from sleep (monitor sleep, not computer)? My wife and I have the same PCs and monitor and we both started noticing this issue recently. Driver issue? [Edit: Okay, hold the boat there was a drive released yesterday let me try that first.]

Same here on the monitor issue. Noticed it immediately when I went from DVI to DP, 980ti here as well. It also hosed with the resolution ... scaling (scrunches whatever is on the screen to 1080p sized boxes with a 1440p monitor)

Looks like Powercolor's dual 390 card is finally available for the low low price of $800. What's funny is that their older dual 290X card is still available for $650 which is technically a better part (more stream processors) with less ram (2x4 vs 2x8).

I wonder if a Kraken G10 would be worth throwing on my XFX R9 290. If the fan dies on it again I'll probably spring for it, provided the 1080 Ti or whatever Nvidia's next ridiculously good GPU will be is out once I'm done school.

I think those are very worthwhile for 290's and so on.  Just keep in mind heat "runaway" if you use Furmark, but otherwise it has a huge heatsink effect for the whole board under normal (100% load, gaming). Not to mention a 40-50* drop on the core itself. As a precaution, people have put little copper heatsinks on the VRMs. I did this as well. Necessary? Probably not, but it takes minimal effort compared to what you're already doing and it costs another $10 or so. As you can see cooling the memory is unnecessary under any scenario imo. Im pretty sure there is another option that includes a heatsink plate for VRMs by Corsair but I've never looked into it. penus penus penus fucked around with this message at 17:37 on Oct 9, 2015 |

I guess its known that Furmark specifically pushes VRMs to truly unrealistic levels, but I imagine if you had say a very poorly ventilated case that the same thing could occur. There is a definite tipping point. However in both cases the actual GPU cores were 40-50* cooler as expected which isn't reflected in those pics. I find the picture interesting just because even without a significant fan or heatsink, the cooling difference is so extreme at the GPU it actually draws the heat away from the VRMs, which one might to expect to be always hotter. But it also serves as a warning that it can run away penus penus penus fucked around with this message at 18:13 on Oct 9, 2015 |

I can tell you as someone who's actually used a G10 with a 290 that the VRMs will hit 120c+ The fan on G10 is blocked by the pump so it can't really hit both sides of the card. Granted, I didn't add mini heatsinks to the VRMs, those could have helped, but yeah it was pretty nuts.

Heck, a die shrunk 290x (390x) taking over the midrange for the next generation would be nice if it meant they could get boards down to 200 watts or less.

Dang, my two week old EVGA GTX 970 with the ACX 2.0 fans and the newer part number has started to exhibit terrible coil whine, along with some very noisy fans. I'm not talking about jet engine, I'm talking about some sort of oscillating howl when it reaches certain fan speeds. I don't know if it is causing the fan casing to vibrate or what, but I'm just about ready to contact Newegg and switch this thing out for the MSI Twin Frozr. I'll see what EVGA wants to do first, though. Edit: It took EVGA 4 minutes to offer an advanced RMA. Guess I'll just play RMA tag until I get a decent card. Has anyone else had a similar experience? Or, should I just contact Newegg and get the MSI Twin Frozr? Is that thing noisy? reagan fucked around with this message at 21:34 on Oct 9, 2015 |

My 980 exhibited coil whine when running certain benchmarks but it hasn't made a peep in any games I've played.

Sorry, I mean that on the bottom image, the Kraken photos show the right side of the boards as hotter than compared to the stock coolers. Is that because the stock coolers are causing the card to throttle, so the Kraken case is pushing more load through whatever part of the card that is?

It's because there's no airflow over the VRMs, the Kraken is a AIW water cooling block that only cools the GPU. To install you remove the fan and shroud (which directs airflow over the rest of the card)

It is doing it ingame, with or without Vsync, and the whine changes intensity when you move the mouse around. That combined with the noisy fan is enough to make me RMA. Or do a return, I am going to have to think about it.

I have a complicated situation, and come seeking advice. My immediate reason for upgrading is Fallout 4; even with my 1680x1050 monitor I doubt my old HD 5770 is going to cut it. However, I also want to pick up an Oculus Rift or a Vive (still deciding) come spring, so I figure I might as well upgrade with that in mind now. My original plan was a 980 TI, but now I keep hearing cards using the new manufacturing process are just around the corner (well, a year-ish, and I usually upgrade my GPU every 4-5 years) and will be a major step up, which makes me reluctant to go all out now. System requirements for a Rift are R9 290/GTX 970; I was alternately considering a 290 as the cheapest option and since I've heard AMD has some advantages for VR, with the plan to upgrade again in 1-2 years. Though what this thread says about heating has me reconsidering a 970 (it isn't that much more expensive), since my PC is in a small and not particularly well ventilated room. Also, are there usually decent GPU deals for Black Friday? If so I might wait a few weeks to play FO 4, especially considering the launch history of recent Fallout games.

At this point, I still do it simply for how quiet it is. I have my fans on at roughly the minimum voltage to make them spin. When you have 2 cards, the cpu and mb all on the same loop with 4 360mm rads it's almost passive. The box fan in the hall is louder than the computer.

Ideally that'd what I like, pretty much for that reason. But as it stands my AIO for the CPU completely overshadows any other noise from even my aircooled card when its really going and im not really worried about that extra 13mhz on the GPU (unless things have changed for maxwell)
