I have an AMD FX 8350 and I just installed an Noctua NH-U12S (was using amd stock before) because it was showing near 65C in HWMonitor while gaming and running a second screen. Immediately when I booted up after I installed my new Noctua I was getting idle temps at 33C which I was amazingly happy about. However now It's showing after some reboots I'm only getting 40-44 idle. I ran prime95 for over 25 minutes and my thermal margin stayed at 27 degrees Celsius throughout the entire time during stress. As you can see in the attached picture Hwmonitor shows my maximum temperature reached was 60C. Are these readings accurate from amd overdrive as it relates to my thermal margin or is Hwmonitor being that inaccurate? I couldn't have a thermal margin of nearly 30C when the max temperature for this socket is 70C.

^ prime95 is ideal for testing CPU temps - & yes those temps are good - ultimately trust overdrives thermal margin over any 3rd party software.

Ultimately during a prime test above 10c is decent ,above 20c is absolutely excellent.

Your temps are maybe 5c or so better than average for that noctua but ambient temp and/or case cooling most likely account for that.

prime 95 is a stability test not a test you use to see if the thermal solution you are using is okay. do some hard gaming or whatever it is that you do that is most punishing on your CPU and check your temps in that circumstance. I am sure everything is fine and hwmonitor has always served me well.

anyways both say that you have thermal headroom so I would think that everything is fine

Thank you for the response Matt, thank you for the information! I have a question for you, what is the more accurate temperature on HWMonitor. CPU Temperature under the temperatures tab or the "Package" Temperature under the AMD-FX8350 tab which shows a max under full stress testing load temperature of 45C which if you add the 27C thermal margin gives me exactly 72C which is the unofficial max temperature this cpu can handle (amd won't confirm). Is that the accurate temperature of what my cpu is? I can't figure out why it says cpu temperature 60C and the other says 45C

all I am saying is that you will never reach those temps while actually using your computer in a non stability testing manner.

CPU temp is socket - ignore - its unreliable anyway ,package temp is core (max of 72c on fx processors) - this is the important one & as you say coincides with the thermal margin result.

I dont use hwmonitor (hwinfo64 is more reliable IMO)

As fkr mentions above - a 27c margin under prime testing will mean a 30c+ margin even under heavy gaming - you are honestly all good on the temps front now with the noctua

Thank you for explaining the difference to me between socket temp and core temp on hwinfo. I can see now that on hwinfo64 those temperatures of 43C are coming from the motherboard, and that those temperatures from what little I know about sensors are not very accurate. This makes much more sense now. My core temp right now on hwinfo64 and hwinfo, as well as correlates with AMD's overdrive thermal margin is an amazing low of 25C and currently 33C. I ordered and installed all new fans on my NZXT Phantom White Steel Full size. Went all Noctua except one 200m that has to be NZXT.

I installed today 3x 120mm Noctua NF-S12A's (rear exhaust and two side intake), 1 Noctua 140mm NF-A14 (Front intake), 1 Noctua Noctua NH-U12 S CPU Cooler and 1 200m NZXT (TOP exhaust). I'm quite happy with the results I've gotten from my new fans, I was using all stock fans and a stock amd cooler before! I have the Ballistix Tactical ram which has heat spreaders that make it almost impossible to use an aftermarket air cooler, the U12 S barely even fits, there is barely a grain of sand separating the fan and my heat spreaders even with this cooler! I am definitely going to get better ram next time.
