Hi, first post and all that so here we go.......

I'm not that PC literate but have Googled for the last 2 days and have tried everything I could so I'm turning to you guys for any advice etc.

Basically got given a PC from my brother, its ok. Its from Mesh with an AMD Phenom II x4 955 Processor, Radeon 4800 HD Graphics card, 8gb ram and an Asus m4a78 - Pro motherboard!
So.....all is good but the fans are a little bit keen to blow all the time (one at the front, one at the rear, psu fan (new psu on the way due to coil whine) and a akasa big fan heatsink thing on the cpu).
Checked out the CPU temp (Bios, hw monitor, core temp etc) and it was 82c. Hot! So I cleaned the dust out of everything, no difference. Bought some Arctic Silver 5 plus the cleaning stuff, reseated the heatsink 3 times (first time I assumed I done it wrong, second and third Im 100% sure I done it right) and no change at all!
The 4 cores temps are all pretty consistant at 35c - 40c so thought Id do some little tests. Firstly, with speed fan I turned all the fans off (I know). The 4 core temps shot up about 10c but the cpu temp stayed exactly the same!
Next (and currently) I removed the PC side casing (inside is very cool, no escaping heat at all) and put a large desk fan blowing in. The 4 core temps dropped a little yet the cpu temp (yep, you guessed i) stayed exactly the same.
Motherboard Temp is 28c - 30c
Also done a couple of load tests and opened loads of programs etc! Core temp rose a bit but CPU stayed exactly the same

So I'm stuck. Kinda wondering and hoping that its a faulty temperature reading and all is good but I have no way of knowing. PC runs perfectly well

Any advice or just words of reassurance (yeah its all fine, dont worry) would be great

Thanks

James

It is probably a sensor. The max for AMD CPUs is 62. The CPU would have died long ago at 82 and the MB temps would be much higher. Also the core temps are usually higher than the CPU temps. I have an SSD that has shown a temp of 128 C since I bought it 2 years ago.So if the comp is working as it should I see no problem.

So your CPU core temps are 35 to 40 Celsius but your CPU temperature is being read as 82 Celsius?

Are you using the hardware monitoring software that came with the motherboard, or some 3rd party tool?

82C would not have killed that processor, it would 'survive' constant 90 Celsius temperatures for prolonged periods. Sure it may throttle back, etc. but 82C will not damage a processor! :pt1cable:

Hey, thanks for the replies.

Arrpee, yeah that what I kind of assumed. Everything seems pretty much spot on except for the cpu temp at 82c constantly!

TheLastDoomguy, yup, Core temps at 35 - 40c and CPU sticks at 82c no matter what (It did once flick to 84c but thats all) . Ive taken the CPU temp from Bios and also used core temp, real temp and HW monitor which all give the same readings for cors and cpu temp

82 degrees will not kill an Intel CPU, but will destroy an AMD processor. Do your research before you give bad advice
