cpu temps high CPU Temps High Idle & Under Load

[V3ptur]

I've had my Corsair H100iGTX for a while now (like 5 years) and I've noticed my CPU temps seem to be quite high but I don't know why the temps are getting too high. I've cleaned the radiator and fans along with resitting the CPU but temps still seem to be high, my system has two 120mm intake fans at the front and two 120mm fans at the top exhausting air out along with another 120mm at the rear. The tempreture of the liquid seems fine and the pump rpm and fan rpm seem to be responsive when underload.

 

Here is what I'm getting when I did the test:

 

• Idle temps are between 45°c - 50°c which is quite hot espeically for an AIO, Usually I'd be looking at anywhere between 28°c - 35°c 
• When under Prime95 load the CPU peaked at 97°c then started stopping some of the workers. The only problem is Prim95 was then only using 45% - 50% CPU usage but the temps were idling at 90°c 
• When taking the tests the room temp was 18°c 
• I have also overclocked the CPU to 4.3Ghz at 1.34v but the temps were running pefectly fine before then for a long time. 

My System:

• Ryzen 9 3900X OC @ 4.3Ghz
• RTX 2080Ti Founders Edition
• Gigabyte Aorus Elite X570
• Sabrent 2TB NvMe SSD
• Corsair HX850i PSU
• 32GB Patriot DDR4 RAM 3733Mhz
• Corsair H100iGTX AIO Cooler

I really don't know what the issue is, should I invest in a new AIO? any suggestions would be greatly appreciated. 

 

Thanks!

It could be the AIO. You should try to check if water is circulating, check bios or HWmonitor to see if the pump is still working or/and try to listen to the AIO while running, perhaps without fans, you should be hearing a quiet hum, additionally you should/may feel vibration in the tubes, either at boot or while running.

Perhaps order a cheap, decent cooler of Amazon, like a Hyper 212, and return it if it doesn't fix your problem.

radiator mount location? (5 years is long enough for permeation to significantly reduce the liquid volume in the loop, this can result in a lack of fluid movement in certain orientations. Ideally top mount rad, or front mount with tubes at bottom of rad)
When was the last time thermal goop was replaced?

Radiator is located at the top of the tower with 2 x 120mm fans exhasuting air out of the system. Thermal paste had been on there for like a year I've replaced it and still getting the same problem, then I changed to a different thermal paste and still getting the same problem. The AIO has a 5 year warranty so I'm not sure if I should just RMA it?

I used HWmonitor and according to that the pump is working and has a responsive rpm when underload as well as the fan RPM. When I boot there is a slight humming from the system which as you said is most likely the pump. I'll try my wraith cooler and see if that makes any change. Thanks!
