I recently built an a10 6800k system for office computing. everything posted up fine, however i noticed the temps in uefi were running a little high (hovering around ~60c on idle) on the stock cooler with no overclock. i wasnt stilling well with those temps plus the noise of the stock cooler so i went ahead and grabbed the cooler master tx3 when i purchased windows. once i loaded windows i went straight for core temp. however, to my surprise it was reporting 0c. i rebooted system and it was still saying 0c. opened up asrock a-tuning and checked under system info where it was reporting cpu temps around 25-35c idle. i then proceeded to d/l AMD overdrive, HWmonitor, realtemp, and speecy. realtemp did not support the 6800k. AMD overdrive, which i would have thought would be the most accurate, is reading 70C on all cores. even on 100% load it says exactly 70C across the board. i'm no expert, but this almost certainly cant be correct. i dont know though. HWmonitor says 25-35 C idle according to CPUTIN, the same temps that a-tuning is giving me. on 100% load the highest CPUTIN came up to was 50C. however, cpu temp packages is around 45c on idle and up to 80C on 100% load. i put my hand up to the cpu and it does not feel anything like 80C. i barely feel any heat coming off the cpu. my lenovo y410p will get up to 80C when gaming and its like a space heater on my lap. this doesnt feel anything like that. speecy, interestingly enough, is claiming the same temps i'm geting from HWmonitor temp packages. around 45C on idle and up to 81C on 100% load. the temps im getting from CPUTIN and a-tuning seem like the most realistic of all the readings, but i don't know. ive read where programs were reporting false temps for the 6800k, i cant help but imagine thats the case here. but i'd also hate it to be a bad sensor that goes unnoticed. any help would be GREATLY appreciated. if its a bad mobo i want to go ahead and get the RMA process going! thanks!

I swear I answered this same question 10 times already today.

AMD Overdrive shows thermal margin. so that 70'C you see means you got a long ways to go before zero thermal margin when your CPU throttles anyway. The only physical sensor on these chips is on the socket and that's what your motherboard reports. Thermal margin is just a calculation but it is very precise, and it's what you want to worry about when you are 100% load.

All that 3rd party Core Temp, CPUID, ect doesn't interpret these signals right.

The temp in A-tuning is socket temp which is a good indicator when you are idle, but less accurate at load.

well, the outside temp of a desktop cpu is much lower, due to the build on heatsink as oposed to a laptop cpu. 80c is ok for that chip, and hwmonitor is accurate. turn up the fan a little if you can, or re apply thermal compound, try to stay under 70c but 80c is ok, but it might slowly age it a little more.

i used pea method on bone clean cpu with arctic silver. with the tx3 and no overclock i just dont feel right about temps that high. i'd really like to keep it under 70c under max load. i'll try resetting thermal paste/cooler. ive turned the fan all the way up and it didnt change anything. i also added a 92mm fractal fan to the rear for exhaust with no change in temps.

thanks for the info man! so what about temp packages? are those temps anywhere near accurate?

There are no temp packages, lol. There are only two temperatures for AMD CPUs as I already stated: socket temperature and thermal margin. The 3rd party software you are looking at is misinterpreting the data into something useless. Just drag those programs into the recycle bin.

damric, so for A10-6800k running 33-37 at idle via the ASUS bios, I'm good? HWMonitor/speccy shows 80-90 running prime95 but seems like these programs are useless for APU chips. Is there any other windows (8.1) base program I could use that reports the load temps correctly?
In my situation, everything works great, idle sits in the norm (viewing from bios) and even feeling around the chip, it feels like there's no heat what so ever as well.

33-37 from the BIOS is probably coming from the socket. It's a normal temperature, but not so accurate. Pretty much the only software I'm aware of that works for the FM2/FM2+ is AMD Overdrive.

"Only" 10 times lol! What topic has more repeated questions? CPU temps or how to apply thermal paste?

Good question. Everyone has an opinion on proper thermal grease application so I don't think that topic will ever go away.

The AMD temp question gets asked so much lately even though I wrote a FAQ, and a moderator stickied it.

I don't even watch my temps anymore. Either on my FX chips or my APU's. If I can run Prime95 for hours on end and compute like it isn't even running I am guessing things are ok.

Reading your sticky is too much work for most people. It actually takes some thinking.....
