CPU temperatures

Helmut · 09 Apr 2017

I have a Noctua NH-U12S on my desktop tower.
Noctua are good quality, decent cooling block and quiet fans, simple fixings, though rather too expensive in the UK.
Also use Intel CPUs rated up to 90°C use.

When adding after-market cpu coolers.
It's important to take into consideration,
the case dimensions and motherboard compatibility,
with the cooler you intend to install.
You don't want to spend your money on something,
that won't fit into the case,
or onto the motherboard and cpu.

Perhaps the thermal paste,
between the current heatsink and cpu has become degraded?

Have you changed/replaced the thermal paste,
to see if this might help?

Hi guys.

I got some amazing result today, and I'm happy with the PC how its running. I took apart the CPU cooler, and I found a ton of dust which had clogged it up from breathing, it looked awful. I had the impression that using air spay cans would have cleaned it up, but no!...

So after cleaning it up, and then applying arctic silver thermopaste on the cpu due it had been worn out, the temperature which on start up was 55c, now is 35c.

So last minute before ordering the CPU cooler, and fans, I believe I got lucky digging more into it.

Nice job, way to go!

Nice just keep in mind few things and quirks about that series of AMD processors. Idle temperature readings are notoriously unreliable and oft wrong by 10 or more degrees even reading them in BIOS. CPUID-HW Monitor and bunch of other programs don't get CPU temps right always, AOD (AMD OverDrive) is much more accurate and provides other utilities for testings and benchmarking.

Hi Mike, I installed the AMD overdrive and these were the results. thank for the AMD recommendation.

I don't know if you noticed but temperature is displayed as a margin to 62C when it should start throttling. So your actual temp is 28c. When you load CPU that number will start to get smaller as temps go up. Anything above 10c is excellent, 0 to 10 good enough.
You can also make use of Board Status pane as well as Logging which will give you temps and other data during use to view later and find minimum and max on all parameters. You can also run stability test while logging.
