Hey my Cpu jumps to 255°C shortly after playing a game or anything that puts any sorta strain on my Cpu but its not running that high clearly :p i have reapplied thermal paste i changed from my stock fan to a H100 recently which made no difference. My Cpu idols at around 22°C and only gets to around 40°C running Crysis 2 Maxed but after a few minutes playing any game it just jumps to 255°C my Cpu is a AMD FX-8120 Overclocked to 4.2Ghz iv tried lowering it but it made 0 difference.

Any idea how i would go about fixing it? every temp program iv used has shown the same result CPU hits 255 and my CPU throttles itself down to 1.4Ghz only way to Reset it is to reset my computer.

if it's throttling, contact the company that you bought it from and get it RMA'd, sounds a bit like a bad sensor to me, i doubt it's actually idling at 22C unless your living in a real cold place

HWMonitor can sometimes act funky if that's what you're using. Here's an example of my brother's machine :lol:

Take a look at FANIN1 and the temperature of the Corsair Force 3 SSD. No way in heck that the SSD is running at 128C :lol: it's still cold to the touch as well.

Are u sure its "throttling" ?!! I really think the chip is fine, all BD chips idle at 1.4GHz when there's nothing to do, its an energy saving feature :D
I still think its either bad software, or faulty sensors, but i'll put gr8 emphasis on d first one . cheers :)

if the chip thinks it's running that hot, it will always throttle, you could try RMAing it and seeing what they can come up with

So i swapped my CPU out for a different one and so far it hasn't jumped to 255 Degree's but its running cold according to Core temp and CPUID HW its jumps between 16 and 25 degree's constantly, speed fan seems to be correct but why aren't the other 2?

Speed fan get the temperatures like the bios. The first is the System the second is Cpu temperature it screws a bit with the other onboard detectors and in some motherboards doesn’t work good but is very reliable.

I use it minimized in sys tray and I can see the system temperature always is more important to me.

hey i have a amd fx 6100 and the same thing happened to me a couple of times so i would not worry about it ,, because amd has only one sensor that is on its 1st core .. but its ma 2nd core thats goin upto 256 deg celcius .. i use core temp to monitor ma temperature and as u can see it takes the readin from 1 sensor and tries to depict the other 5 core readings,, at first i was shocked and thought of replacin ma processor,, i have gigabyte 78lmt-s2pt .. which has Easytune6 to monitor the temp and fan speed and stuff which shows cpu temp as 42 degrees.. happened while i was playin Dishonored.. its all cool and ur processor is just fine.. chilllaxxxx
