AMD CPU Running hot under load?

My motherboard died recently and I had to swap it out for a newer model one.

I cleaned the heatsink & removed the old thermite paste using 80% mix rubbing alcohol. Let it dry and was sure not to let my finger touch the clean surfice.

I put the CPU & Heatsink (stock) back into the new mobo using ANTEC 7 Diamond paste (it was pretty thick in my opinion...)

Now i'm getting some old temps.. i wish i monitored my old computer better so I could see just how abnormal these are but low 60's is about normal when i'm gaming now and i'm curious if that is too high.

CPU: Phenom II x4 945 Deneb 125w
1x 120mm's running max speed on front and back of case.

For stock heatsink that isn't too bad. You are good.

I've got a Phenom II x4 955 BE and with an aftermarket cooler I'm hitting about 55C while under stress. I think your max of 63C is normal for a stock cooler.

What I am a bit worried about is your Voltages. They seem a bit all over the place. Not sure if it's just false readings. How old is your PSU and did it get any damage when your old Motherboard died? (maybe your PSU was the reason for the MoBo to die in first place).

PSU is a OCZ 700w Fatality series. I was one of the lucky ducks who got the old 600w OCZ Stealth series PSU's 4 or 5 years ago and it caught fire. I got the 700w as the replacement.

PSU is about 2-3yrs old

I powered the PC up and let it sit for a minute. then started World of Tanks with Medium-High settings. the CPU fan pushes over 5,000 rpm's to keep it cool.

Everything is about 4-5 yrs old except:
Motherboard - Brandnew
SSD - Brand New
PSU - 3yrs


Found online the Normal Operating temps is between 55-62 with teh 95w version up to 70.

so long as i'm under 70 i shouldn't worry i think?

I don't know what to say. I really hope these are some false readings but you are getting 8V on the 12V and 3.3V on the 5V etc. It doesn't look good to me.

How to check? Is under a real problem? I could see going over being a issue.. I bought a corsair 500w psu.. but I had planned on returning it since my old one still worked. If it's not working right i would like to confirm someway before i open the package.

Yes under volting is a sign of a failing PSU. Though with 8V I don't think it should power on. Either way If you have a multi-meter go to your computer while it is on and find a molex connector (large 4 pin) Two of the wire are ground 0V and one is 12V the other 5V see what the actual voltages are if the match up with Hwmonitor shows it should be replaced if they aren't post it back here so we can tell you if it is alright with the actual voltages.

Yeah, this would indicate failing PSU but again, we can't be sure the readings are correct.

I was trying to find an alternative software to try and measure them. Aida 64 should be able to do that but the trial version don't seem to allow you to see the readings. Or at least not on my job PC. You could give it a try. But as you can imagine the only way to be absolutely sure would be to measure the voltage using some proper hardware gadgets I bet not everybody keeps at home - stuff like this

I'll have to look for a volt meter to see if I have one.. I restarted with Cupid showing same results.

I did restart a 2nd time and went into bios.. it showed different

12v was 12.012v
5v was 5.135v

so... either Gigabyte UFI Bios is wrong or Cupid is wrong.

Previously the computer had locked up and crashed a few times randomly, before the motherboard finally died.

Those temps are fine for stock cooler.. no worries
