[SOLVED] Intel i11900k CPU reaching 100c while gaming and stress testing

[BarrV]

Hi, I built my pc 9 months ago, and I've been using it mainly for gaming and some CAD programs. About 2 weeks ago, it started crashing and rebooting through blue screens many of the times. I've been troubleshooting my pc and realized that my idle cpu temps are between 45-55c degrees. However, while gaming and during stress tests, the cpu temps rise very quickly to 100c and thermal throttles through all the test or gaming session time. I tried deactivating XMP, and high performance power manangement profile on windows, setting fans and pump to maximum values and cpu temps continue to rise to 100c. I would really aprecciate some help in order to solve this issue.


Thank you very much!

I suspect your AIO is the culprit. The 240r I know has a recall, due to gunk building up in the fin stack, of the water block. The 360r may have the same issue.

maybe reapply thermal paste and make sure you don't have air trapped in the pump or the radiator (ex: hose up config)

If the issue is indeed related to my actual AIO, the best option is replacing it? If it is, which AIO or cooling method should I get on?

The 360 version does indeed apply for the recall.

MSI is recalling MAG CoreLiquid 240R/360R AIO coolers for hitting abnormally high idle temps

Not cool, guys. Thankfully MSI is being proactive about a product recall.

Your case is an excellent one for air cooling, and I would consider a NH-D15s replacement.
As it is now, the most cooling needy part is your graphics card not so much the cpu.
With a front mounted radiator, your graphics card and motherboard VRM heat sinks are cooled with warm incoming air.
