FX8320 with Hyper EVO 212 idles at 45 celsius

[guv8T6]

Hi all.

Recently completed a build with a Fx 8320 not over clocked at 3.5ghz and an Cooler master hyper EVO 212 attached. The temp on hwmonitor and cputemp shows at 40-45 idle and 80 when close to full load (BF4 on ultra) . Is this normal???

No, that is not normal. You should be seeing temps at under 20C at idle, maybe 40-45C at load. An FX CPU should never get above ~65C. Check your temperature with a different program (such as CoreTemp) to make sure the readings are accurate. If they display the same temperatures with a different program, then you need to reseat the cooler. Make sure to properly clean and re-apply all thermal paste, and install the cooler while checking to see if proper contact between the bottom of the cooler and the CPU is maintained.

What he said, except for the under 20C part (depends on your room temperature).

20c on a air cooler? That might be an overstatement. I would think 30c'ish but 20c I would think only on a liquid cooler.

not even on liquid, unless you have 10C in your room, best call it like a good liquid gets you 5-10C over ambient, a 212evo should get your 10-15C over ambient on idle

and around 30-40C over ambient on full load. this assuming good paste application and quality and a decent case airflow.

Idle temperatures are usually fantastic on air coolers, and sometimes better than water coolers, due to the fact that an air cooler also cools the VRM, which helps shave the temperature at idle. The reason you see more benefit from a water cooler at load is because the heat of the CPU is more important to cool than the VRM. But I digress. The FX series usually run VERY cool when properly cooled, and will likely sit in the high teens to mid 20s, as the poster after me mentions, depending on ambient temp. Given, the FX series also has a much lower thermal ceiling, and throttling can occur at temperatures as low as 60C, but is more common at 65C-70C.

I have NEVER seen a air cooler have cooler idle temps or load temps than a good water cooling system.....even closed loop like a h100i. Air coolers just wont beat a custom water cooling loop. Aint gonna happen.

If your motherboard OEM has a temp utility use it to compare with your other temps.

Then, there is always the finger test. Crank it up and lightly touch your finger to the sink-base. If you pull back a smoking nub you have a problem ... if not, there may be an issue with the sensor reading.

You guys have to keep in mind that there is a difference between the core temp and the socket temp. For AMD's FX series processors, they are notorious for misreporting the core temps at idle (mine currently says 13C, which is ~10C BELOW ambient, and is impossible) but my socket temp is 34C, which is correct. Under load the core temp becomes accurate at ~58C whereas my socket temp skyrockets to ~70C.

guv8T6, which program are you using to measure your temp, what does the temp name say, and what are your ambient temps?

 

[guv8T6]

The ambient is about 30 degrees c. I've used hwmonitor and core temp both coming up approximately the same. I've seen the idle at 20 to 25 then the second I open say Firefox up to 35 to 40

Ok those are correct if you're using core temp. Remember what I said about it reporting idle temps below ambient (which is impossible)? That is exactly what is happening. And whenever you put load on it, your core temp "jumps" so high, but is really only just above ambient, and is what it should actually be. There is nothing wrong with the current situation you just described.
