im trying to figure out what a normal running temp for my FX-8320 should be when im cooling it with the H100i liquid cooling system by corsair.

at idle it hovers around 32 degrees C at first start up then goes up to about 38 at idle and proceeds to rise when playing games such as Vindictus (free MMO) and League of Legends.

after one game of league i check my cpu temp and its reading at 40-44 degrees C is this too hot? im currently waiting on the delivery of 4 more corsair air penetrators but i'm not sure how much these will help .

 

my full system build is as shown here

am i running too hot? is it ok? new to AMD processors so idk whats too hot my buddy's I5 is running at like 26 degrees C while at idle with the same cooler tho he has more fans currently then i do (but we have the same case)

i also just added new thermal compoud (Arctic Silver 5) in an attempt to lower the temps a little doesnt seem to have helped much.

help in figuring out the proper running temps would be appreciated

when you say you added Arctic Silver 5...  I hope you thoroughly cleaned off the old TIM first and applied the proper amount. (small drop in center of heatspreader about the size of a small lentil)

Also are you drawing air from the outside of the case? For reference, my slightly overclocked (4.6ghz) FX-8350 with a Corsair H60 using dual fans drawing warm air from inside the case peaks under Prime95 at 56°C.

The Max 24/7 temp per AMD Engineering is 61C so you're fine with anything below that temp when under maximum load. This is the same as the FX-8120/8150 CPUs. Idle temps do not mean anything. The max 24/7 temp is all you need to be concerned about under max load.

Don't try to compare Intel CPU temps to AMD. The typical temp software IMPROPERLY reads FX temps except in the 40C-70C range - per AMD Engineering. FX temps are way off at idle.

AMD has been very poor in listing the max temps for new CPUs online.

Arctic Silver 5 is a good TIM but any of the top 25+ TIMs will produce the same temp within ~2C.

Building a reliable PC involves more than just assembling the parts. You need to be able to configure all of the BIOS settings appropriately. This can be quite involved and frustrating as it can require a lot of trial and error with stress testing. It is however often the only means to get a 100% reliable PC.

Liquid cooling is much less sensitive to TIM than air cooling. As you can see from the chart, cheap thermal tape only performs 2°C worse than AS5.



Additional results are Here on TomsHardware charts

I use IC Diamond 24K, which is some of the best non liquid metal TIM you can get, but it is also horrendously expensive and it should not be used on an exposed core, such as a GPU, as it will etch it.

So the bottom line is ANY of the top 25+ TIMs will deliver the same CPU temp within ~2C - as originally posted. This has been confirmed by numerous reliable review sites.

There is no magic in TIM so pick the one that makes you happy. I suggest that enthusiasts not be a sucker and pay stupid prices for a couple degees C when it makes no diff in CPU performance.

Readers that live in an area of higher ambient temperatures and don't throw too much money at airconditioning may wish to spend extra for those (actually) 2-4 degrees!
