AMD Phenom 955 overheating?

Forum CPU & Components : CPUs AMD Phenom 955 overheating?

My phenom x4 955 keeps going at high temperatures and the fan is quite loud which is kinda creeping me out as my old pentium 4 would never go this loud.

System Specs:
Amd phenom 955
Ati radeon 6770 1gb
4gb DDR3 1333mhz ram
500gb Samsung spinpoint f3 hard drive
Corsair cx 430W v2 Builders series (1x 120mm in psu outtake)
Msi 870a-g54
DVD RW drive.
1x 80mm fan (rear outtake)
1x 120mm fan (front intake)

Here is the idle stats

and here is the stats when playing minecraft. Which is quite a light game. It goes very loud. Is this normal?

If you are using the stock cooler, the temps are normal. Maybe you can try to reduce the CPU voltage in BIOS for reduce the temps or get a better cooler.

ok it seemed i didnt put the lever down because i was scared of it breaking. But still the temperatures rise up to 50degree C, is this normal while playing minecraft on full?

Your temps look fine, some 955's get pretty warm.

If its noise you dislike then get a larger, quieter aftermarket cooler.

It will also reduce your temps.

I have a 955, and temps were approaching 61 degrees celsius under load. I reapplied Arctic Silver paste to the CPU and saw the temp drop about 4 degrees under load. After failing a Prime95 test after half an hour, I bumped the RAM voltage up .05, and now I rarely go above 53 degrees on the CPU temp. (This is using a Scythe Mugen 2 cooler, by the way).

I don't know if there's any scientific reasoning that suggests bumping up RAM voltage would result in the CPU running cooler, but that's what happened with me.

Probably just your paste bedding in.

This is a good guide for re-applying paste.

Drop the voltage to 1.25V in the BIOS, most mobos give too much juice on auto.

Reply to mosox

Looks like cool n quiet is on, wouldn't manually setting the voltage effect that?

hmm i dont know how to do that exactly. But i already reapplied thermal paste. Temperatures didnt drop much.

what i did is i had 2 alchoholic cloths and i cleaned the bottom of the heatsink and also i cleaned the top of the cpu.

I then added a pea size amount of akasa thermal paste as that was all i had (well my friend had) and i added a pea size. then i put the heatsink on the cpu and i twisted it a tiny bit to make sure it spread everywehre, dunno if it idid, i asume so though.

And then i fitted it on again. It seemed the first time i didnt put the latch on or the lever on properly because i was scared of it breaking...

but yes when im playing minecraft it goes at 52degree C after a while. Is this dangerouse?

At what temperature should i be worried at? Give me a range.

For example at this temperature you should be wary, and at this temperature close and shut down everything.

thanks, im just really worried, so noise is normal for the phenom 955 huh?

Also i think temperatures decreased after adding the thermal paste, but not too sure. But yes when i put the lever on, which i was scared of breaking at first, it definately decreased in temperature. Before where it would go to around 58 degree C it now stays at around 52 degree C.

You have a C3 revision that usually runs more cooler than a C2 and with low voltage, start with 1.3V in BIOS and test for stability if it's works, low the voltage again and test for stability.

ok can you give me a step by step on how to reduce voltage? thanks

and can someone tell me whats a safe temperature range, and whats a dangerouse temperature range please?

Reply to pkhamidar2com

55ºC or above is a problem for me.

Go to your BIOS, look for the CPU Voltage option and change it from "Auto" to 1.3V, press F10 to save "y" to accept, your rig reboot immediately, after that try too long on and test for stability with LinX or pime95

btw is 55 OC very bad? thats what it usually runs at when playing minecraft, i still need to see what happens with other games though.

Reply to pkhamidar2com

btw i will be doing that voltage thing though.

can someone, or you saint19, explain what voltage even does or is? i dont understand, what does it do?

Reply to pkhamidar2com

voltage is sort of electrical potential, on its own such as a battery not connected to anything it stays potential, but when current is added to the equation (circuit is completed, current is measured in amps) it allows this potential to flow. This is how VxA=power works. so the higher the votage say 1.4V with lets say 17 amps, you get an output of about 24W. put that voltage down to 1.1V you get 18.7W which is less power and therefore less heat. geddit now?

i know you dont have a high budget, and you want something that is quiet, while also easy to install and effective, and this would be a great option meeting all those criteria at only £13.40 with free P&P:

ok i will set it to 1.3 some time today, my little brother wont let me touch the computer right now, playing some silly flash games, and will probably throw a tantrum if i turn the pc off....

btw by setting it to 1.3, that means that the maximum it can reach is 1.3 right?

So does that potentially basically underclock my cpu or something?

are you sure its not dangerouse to my cpu?

yes, undervolting is not whats dangeorous, its overvolting that could potentially be dangeorous. Be sure to test for stability by stress testing after undervolting (prime95) as said above.

ok ill do it now

Reply to pkhamidar2com

ok i tried to change the voltage, its set to auto but the auto is greyed out and i cant change it. What should i do?

ok i also found out cool n quiet is set to auto. Should i enable it or leave it at auto?

Edit:

i also found out by taking the side pannel off my case, the temperatures when playinbg minecraft are only around 46-47 degree.

Also the case is in a confine little space where most of the case is in like a little boxy area, do you think that makes a difference or is it just a bad case?

I found out how to change the voltage of my cpu via bios, but when i try to go to 1.38Volts it goes red and says its not reccomended.

should i ignore this message and just go all the way to 1.3v like reccomended?

have you tried the 'Load Optimised defaults settings' from your BIOS, your mobo has great reviews partly thanks to that feature.

ok ill try that too, ill do it now

Reply to pkhamidar2com

ok i did it, pretty much the same, core voltage is at 1.4V, temperatures while playing minecraft on highest settings with case pannel shut is 50-53 degree C....

should i really go down to 1.3 even though the bios doesnt reccomend it... im worried it might mess up.

usually on 53 degrees though... i dont mind the noise.... but i would like to keep temperatures down. Noise is something i can live with.

is 53 degree dangerouse. Should i lower the voltage?

heres a recent thread on a phenom 965 running at 3.4Ghz, and that is running at 1.2V so im sure 1.3V @3.2Ghz is fine:

sounds ok, just a bit worried about messing up the cpu....

also thats a 965, so thats going to have better stability isnt it?

also that person is using a different cooler.

yes they are using a different cooler, the phenom 965 is the same as the 955, just clocked to 3.4Ghz instead of 3.2Ghz, so if a 965 can run @ 3.4Ghz at 1.2V a phenom 955 can definetely run @ 3.2Ghz at 1.3V.

I know of 955's that run at 70C under load and they are still going.

I'd say anything under 60C should be fine.

Try downloading and running OCCT to check stability and load temps.

try using RMclock for undervolting. use this to guide you.
