Hi all,

As the title says, I've noticed recently that my CPU temps are a little high. At idle they sit at 38c in a room temperature of 15c.

While playing Andromeda I was getting BSOD, memory management and watchdog timeout.

These only occur while playing Andromeda, anywho I've reset my BIOS so my CPU is no longer OC'd and using PRIME95 my CPU is still exceeding 90c. I've also cleared away any dust with no effect.

My CPU is the Corsair Hydro H75 in a NZXT H440 case with three Corsair fans in the front and two at the top..

The only thing that I can think of doing is reapplying thermal paste as it has admittedly been a while.


Anyone else have any other advice other than thermal paste?

Thanks.

You could try feeling the tubes. If they feel cool or just one feels cool. My thoughts would be a problem with the heatsink.
- Pump failure
- Clogged lines allowing low or limited flow
- Low water levels
- Air in lines

You could try seeing if one or both of the lines get hot or detaching the radiator from the case to see if you can hear water sloshing around.

Do you have an old heatsink. If not you can try a cheap LGA1155 heatsink and see it can keep the CPU at reasonable temperatures. Personally I wouldn't risk booting again with those temps. Buying a cheap heatsink for testing is a lot cheaper than replacing a CPU which has overheated one too many times.

I'd use the motherboards utility for fan speed control for a much more...

I'd use the motherboards utility for fan speed control for a much more aggressive curve. So it hits 100% at say 30C. Just to see if the CPU can stay cool with this heatsink. The Cryorig M9i is a descent heatsink. It's not for heavy overclocking but should keep that CPU cool at stock speeds. Once testing is done you can slap it in some other computer to make it quieter.
