CPU "overheating" at 80 degrees underload?

Open
JoshuaCrotts

Hey, I have an AMD FX 8320 @ 3.5 GHz CPU, and underload (Playing BF4) I am getting temps of 80 degrees. (WITH core temp measuring) What cooler should I get that's GOOD, cheap and has support for AM3+ socket to keep my CPU a lot cooler? (Preferably under 55 degrees celsius underload) Thanks!

Check your thermal paste. Even with the stock heat sink, it should not hit 80 degrees. In all likelihood, the thermal paste is not applied properly leading to improper heat dissipation. What temperature does the CPU idle at?

25-40 degrees celsius

What cooler you have? I have the similar CPU, FX-8350, my cooler is "Noctua NH-U9B SE2"

The Stock AMD one. Stock AMD paste too. Is there a way to check for the proper name of the cooler?

lol, then it should not surprise you....AMD stock cooler is shit, and thermal paste bad, buy this cooler "Cooler Master Hyper TX3 EVO" 20€ and very good.

Agree with sviat93 - the stock AMD stock cooler is bad, and the stock thermal paste is not great either. You should see way lower temps with a better cooler and paste. Good luck!

Are you sure it's seated correctly? Maybe dust buildup in the fans? Stock coolers aren't bad. They're designed to keep the CPU temperatures within spec and nothing more.

I didn't build it. (DONT KILL ME) I will most likely be resitting it with new thermal paste (Arctic Silver 5) this weekend. Will this lower temperatures slightly?

Possibly a small amount. If you have the option of a different paste, then don't use AS5; if not then go ahead.

I'd say it's more a combination of dust (if you haven't cleaned your computer recently), and poor airflow.

No, I don't really have another option. Also, the PC is BRAND NEW. I just got it July 10th! How can dust already be in it? lol

You should buy a new cooler, it comes with good thermal paste, this will be a lot better than buying Artic Silver 5 even if it's the best thermal paste but keeping the stock cooler.

Sounds like the same issue I have under heavy load. The reason might be different in your case but for I found a lot of dust in/under the fan of the CPU (after dismanteling it). Cleaning it (twice a year) fixes the over heating problem for me. Checking it before u spend money doesnt hurt :)

dont worry thats ok.....

i have a phenom x4 9950(i know thats old im currently looking for a replacement but couldnt find anything) till 3-4 month ago cpu temp under heavy load went around 100 degrees celsius .......(that was for somthing around 2 years )....

after that i re-apllied thermal paste and the temp goes down to 80 under heavy load ...after that i oc ed the cpu a little bit(from 2.6 to 2.91 ) and the cpu still works like a champ....i didnt measure the temp after oc....

anyway cpu is hard to kill....
