CPU heat issue.

[Panzerlang]

First experienced in CloD, the PC would freeze with a continuous high-pitched scream from the speakers on hot days (20c). I put it down to a code issue in the game but yesterday it happened in BoS.

 

I have a Corsair H50 water-cooler and my BIOS monitor tells me the pump is working ok and the rad-fan certainly is. After re-doing the thermal paste yesterday the temp is worse. In a 20c room at idle (1600mhz to 2000mhz) on 3% load I'm seeing 45~55c. Using Prime-95 the temp immediately shot to 90c+ and would have gone higher if I hadn't terminated the prog.

 

My rig seems to be functioning ok in non-game use, which tells me the CPU isn't damaged but I'm wondering this...is it possible, having had the CPU over-heat to the point of freezing my PC several times, it can now be running much hotter due to damage? Or is it possible the pump has failed in the cooler but the BIOS still gives a reading for RPM? If the pump isn't connected to the CPU-fan header on the mobo I get a boot-up alert telling me so. Otherwise the BIOS is telling me 1400rpm or so.

 

I've been fixing PCs for over a decade and have never before come across anything like this, hence my asking here. TIA for any input. I'm thinking new cooler~new CPU.

It sounds like a a bad pump. If you still have the stock cooler for your CPU, use it and see if it sounds your problem.

What cpu are you cooling with that H50?

It may not be enough for it.

I am running an I7 4820K overclocked to 4.50 ghz, but running an H100i and I get very good core temps.

Idles in the 26-27c range, gaming stays below 50c, stress testing stays below 70c. ( core temps).

 

Have you checked our GPU temps lately? Freezing with the high pitched scream may be more due to the GPU.

Your cpu is fine, those things will shut themselves down if the core temps get too high to cause thermal failure.

But sounds like you need better cooling for it, or perhaps your pump is starting to fail on the H50.

Thanks guys, it's the pump. It seems to work when the case is on its side but not stood up. New cooler is on the way (Antec 950).

 

Avoid ASUS thermal paste, turns to clay after a few seconds exposure to air.
