My CPU runs very hot

It's an AMD A8-5500. Not great, I know. But it gets the job done for the more basic games out there.

Anyway, under load, the CPU reaches up to a staggering 90c. The CPU's average temperature, according to AMD, it around 70c. This computer is four years old, and hasn't been cleaned much. But since I am going to clean the thing, I am thinking that I should reapply thermal Compound. Would that help? If so, which one should I get?

Install AMD OverDrive and check the thermal margin. If the thermal margin is 0 or negative, that means your APU's temp is not at all safe.

Other programs tend to be inaccurate about AMD APU temps.

Interesting. Speccy says it runs at 90c, but on OverDrive, it's running at a cool 20c on Idle.

Cuz Speccy is wrong :)

It usually is for non-APUs too. HWiNFO is reliable (but not for AMD APUs).

(20C is good. Overdrive reports the delta, not the actual temperature.

Speecy might as well be pulling temperatures out of its *** as far as AMD CPU's are concerned. AMDOverdrive works on a scale of 70 - 0 with higher being cooler. At 20C you only have 20C of headroom before throttling or a thermal shutdown. At idle that is bad since the CPU is barely working, at load that is decent.

Okay. I assume I should go ahead and reapply the thermal paste when I get the chance?

I would reapply the thermal paste whenever possible.

Okay. Can you make an educated guess on how much temperatures would improve with a new thermal compound?

Start with Buddha's suggestion first.

As for the cleaning, it is always a good thing to clean about every other month to fight dust build ups (specially problematic in vents/fans). If you have been using the PC for 4 years and never cleaned it up, you could also reapply new thermal paste too. A good inexpensive pick is some Arctic MX4.

I don't clean it every monthe, admittedly. ( I should know better), but I have cleaned it several times over the four years of having this. I think I roughly clean this PC out six or seven times every year. But I will definitely do what Boda said, and reapply the Thermal Paste. I'll be getting a new PC sometime soon, but I still want to take good care of the one I have.
