Is my CPU Defective

Hey guys well about a week ago i installed for the first time a after market cooler. It wasn't anything fancy it was the cooler master hyper 212 Evo. But my First CPU was the AMD FX 8320 and i use to get around 64c under heavy load (streaming) with the stock CPU cooler then AMD send me the AMD FX 8350 and i decide it to buy a hyper 212 evo. Now like i said 2 weeks ago i installed but i notice that when im gaming it gives me the warning of reaching 65c. But i thought that the 8320 and 8350 where suppose to produce the same amount heat since both of them use the same voltage. Besides i have the 212 Evo on the 8350 so do you guys think i should upgrade cooler or remount it. Also i am running the 8350 at stock which is 4 ghz and i used the included thermal paste since everybody said that cooler master included thermal paste was great. Do you guys think my CPU or heatsink are defective ?

Hi there,

No nothing is wrong with your cpu, 65 degrees is not that high.. it's about a normal limit for yours just don't get it above 70.
Based on what you're saying there could be a number of things you can do to further lower the temperature..

First of all you could get a better thermal compound, metal based ones usually work best (I use arctic silver 5). Even if you don't get a new one, make sure you didn't use too much. You should only have a very very thin layer of thermal paste (1mm is too thick already!) as both metal surfaces are completely flat and when they connect they actually conduct heat better than the paste.. the paste is for the small micro imperfections where the 2 surfaces actually aren't touching so yea about a...

Also be sure that you tightened the screws as much as possible.
And finally thermal compounds take some time to find their place and settle in the imperfections which is called a burn-in period so your temperatures might stabilize later on.
Hope this helps!
Cheers and good luck!

Thanks for the reply and i heard that 65c was the limit it should be and every time my CPU get near 65c it gives me a warning sign. And i was thinking about buyin MX-4 is that a good thermal paste?

That's weird, I've got the FX 4130 and even under heavy load it doesn't even get in the 50s. I have the hyper 212 plus with an extra fan but I don't think it would be that big of a difference.

Hi again :)
I don't think a new thermal paste would get you any further than you are right now. (just for the record it would give you a few degrees.. 3-4 maybe.. but you probably have other stuff you can do before that)
If you checked the tightness of the cooler and the amount of paste as I suggested earlier and they're all fine there could be other factors involved.
You're saying that you are running at stock speeds, but does your motherboard agree with that? Some motherboards (kinda many these days) have auto-overclocking features which only overclock stuff when needed.. also asus even has a software for this called ai suite which overclocks your cpu on the fly when under heavy load. Maybe you installed something similar since you got your new CPU (or the old one reacted better and remained cooler). It could be that when you installed the new cpu some cables were left in a different position and are somewhat blocking airflow.. or you repositioned your pc and something close to it (a desk maybe) is blocking the air.. and so on.
Either way if your temperatures peak at 65 and won't go any further then it's not such a big deal. I know AMD rates their processors for 65 degrees but that is the 'extreeme safe' value... most processors won't present any problems not even at 75 degrees.

Hope this helped and if you find out anything let us know!
Cheers!
