CPU Thermal compound - Odd voltages/temps?

Unicorn · 28 Apr 2013 at 17:33

Been noticing high temps on my CPU Idle on my Phenom X3 8650 (Its running stock with an Freezer 7 Pro rev 2 with MX2 Compound i was getting 48 degrees C idle. Odd so i pulled it apart today like i had planned to and found this..

Note the HS did have abit of paste on but the circle in the middle again was bare :S

This isnt good considering the cold plate on the HS only covers the middle of the chip fully. Could i of caused any damage?

Also the voltages are all wrong its meant to run on 1.25 stock and its currently pushing 1.38 through my chip which i know wasnt helping the temps. Chips never been clocked though which is worrying me most :S The board/chip/ram was pre-build by an OCUK competitor and i chose a none overclocked bundle. Why would they push 1.38v through a stock chip :S

Note this is about 4 years old now the board/ram/chip so whatever damage this voltage has caused its been doing it for 4 years.

Some advice needed really? Will it of caused any damage except a lot of heat unnecessarily. Should i drop the voltage down to standard voltage of 1.25 and test it?

re paste and drop to stock voltage and test

it shouldn't have done any damage

I have pasted it and spread using a card this time as i don't like the pea method, Attached HS and its gone on okay. Still rebuilding the system at the moment as i took it all apart to tidy the mess of cables and merge my drives into a bigger one.

Im on an ASUS M3N78 Motherboard i do wonder how accurate the voltages are sometimes. My 5v shows at 6.35v which i know is wrong as i tested with a multimeter. Checked using CPU-Z and Speedfan they both confirm the voltages along with the BIOS so ill try drop it and see what happens

I have used these in the past .... No mess or having to work out if you have full coverage

Yeah i hear good things about liquid metal but its a mess

Maybe when i do my ITX build as lower temps will be essential then

CPU's are generally pretty hardy, while it can't have done any good I doubt it's done any major damage. For future reference, it appears you're quite generous with the thermal compound! I'd say a pea sized blob is too much, it's more of a grain of rice sized blob.

Yeah i did that :') I did a pea size blob i kinda went by the markings on the mx-2 tube which don't appear to be accurate

Just an update, 30 degrees now idle with dropping the voltage to 1.25, Updating the bios and properly applying Thermal compound

More than happy! Off she goes back under my desk again
