CaptBromerica Posted December 27, 2020 Share Posted December 27, 2020 Brand new pc - my H100i will hit 60c within about an hour of playing any game, and begin flashing red. This seems like a relatively low temp for the cooling system to start going into failsafe mode - is there any way to raise that temperature threshold, or is this something I need to be worried about? The case already had 3 fans at the front, and the guys that built the PC for me mounted the cooler fans directly behind those. I'm assuming that may be why it's heating up so much, and thought about moving the cooler fans to the top of the case to blow the hot air directly out, rather than circulating it around the case, but didn't want to go that route if I don't have to.

c-attack Posted December 27, 2020 Share Posted December 27, 2020 As in "H100i Temp" to the right of the pump picture is 60C? Yes, that is a serious problem and way outside the normal range. That is coolant temperature and most people will stay between 20-40C. At 60C, your CPU will idle at 65-75C with load at near maximum. Which H100i is this? If H100i GTX/v2, make sure the MB header supplying power to the pump is set to 100%. All newer H100i models (Pro, Platinum, XT, Elite) use a SATA connection to power and you can't cut the voltage to it. If the header is already at 12v and the pump running in the expected 1900/2700 rpm range, then it's time to contact Corsair Support or seek a replacement cooler.

CaptBromerica Posted December 27, 2020 Author Share Posted December 27, 2020 Correct, the H100i temp is hitting over 60. It's an H100i Elite. The pump is currently at 2460 rp m, but H100i temp is 64.70. GPU temp at 80c (3080) and CPU core temps 63-67 (i9 10900k). Link to comment Share on other sites More sharing options...
c-attack Posted December 27, 2020 Share Posted December 27, 2020 This is a brand new Elite? Normally this is caused by anti-corrosives mixing with excess glue (or something) and clogging up the cooling fins reducing flow rate to near nothing. When this happens you typically will get one hot and one warm/cool hose on the unit. The air coming off the radiator will be cool. Heat is trapped at the CPU block and not making the necessary trips through the radiator. However, given the obvious new state of the cooler, it would be prudent to make sure this isn't a false positive on the coolant. In a true blockage, you power on first thing after a cold boot and everything looks fine. However, from the moment you boot up the coolant temp will start to slowly creep up and it doesn't stop until 50-60C. Compare this to an environmentally unfriendly state. The coolant temp will stay cool as long as you are on the desktop, browsing, watching videos, etc. But after gaming the coolant temp goes way up and stays up because the interior case ambient temperature is also 50-60C and the coolant can't be any lower than the space in which it resides. 60C is still really high for ambient induced temperature, but not strictly impossible. Motherboard sensors, RAM temps, drive temps, etc. can be used to help estimate the interior temperature. The other odd thing we have seen is a few coolers have false positives from an LED effect in the temp sensor. I don't think this has ever been reported for the Elite, I would not expect it on the OLED screen, but if you set the pump LED to black and the temp drops 20C, then there is an issue with that. You often can spot this because the coolant temp will read in the 50s, but the CPU temp is a standard 30ish at idle. Coolant temp is the minimum possible CPU temperature, so red flags wave whenever you see CPU temps measurably under the coolant temp. Link to comment Share on other sites More sharing options...
omgitsrichie Posted December 28, 2020 Share Posted December 28, 2020 I don't have a solution but I'm following this topic since I've had similar issues with 2 brand new Elite Capellix units now. My issue is nowhere near as bad as yours but my coolant temps do get abnormally high (even compared to a 5-year-old AIO I tested with the same build). I feel like there's a QC issue in regard to the coolant flow with these Elite Capellix units... Link to comment Share on other sites More sharing options...
