Overheating after transport

Hi Guys,
I recently moved house and had the self-built PC transported in a removal box.
The power supply was on its last legs and finally gave up after three starts of the system so I replaced the Antec True 380W one with a no name 400W power supply.
That new power supply doesn't has the connections for the CPU fan regulator so is now run faster than before, I think, I've no way of testing that.

I noticed that the system ran a lot hotter under load, quickly ramping up to 80ºC tripping the boards alarms. I noticed that the heat sink wasn't on properly, probably due to the transport. It has some clip on screws which I put in which improved things a bit but the system is still heating up a lot faster than it should.
I checked in the BIOS and it's actually not overclockled as it was before so it's actually running slower and should be cooler which is not the case.

After all this, here are finally my questions.

Could it be that the thermal grease has been damaged and do I need to replace it?

Do I need to worry about the voltage settings in the BIOS after changing the power supply, i.e. could that be the reason? Voltage Control is set to Default at the moment, it looks as if the system is slightly overclocked from 2400 to 2448Mhz.

Thanks for your help in advance!
 
no name PSU is probably a bad sign.... how much was it?

you could try reseating the CPU but id look at the PSU first
 
The power supply was £30, but it's a new one. I just mentioned it as it was a recent change to the system - would it cause overheating of the CPU?

I probably didn't express that properly, the CPU overheats, the rest of the system is OK.I'm measuring the temperature with CPUID Hardware monitor and while the CPU temp shoots up the rest of the system is OK.
 
hmm ok, it probably isnt the PSU causing it to over heat, it may have, as you said, got knocked in the move. i would try reseating the CPU and see if that helps.

going back to the PSU, what are the specs of your PC, would they be likely stressing the PSU?

personally i wouldnt run any system off a cheapo PSU, as if it blows (which it most likely will do if stressed) then it will take other things with it.....

let me know how you get on
 
Thanks for the reply.

Components first, I've got a Q6600 CPU on an Abit IP-35 motherboard, 2GB RAM. CPU cooler is a XIGMATEK not sure about the correct version but it might be a HDT-S1283.

I us a 2 year old graphics card, ATI 9x00 if I remember correctly (doing this from memory), DMX6Fire soundcard, wireless network card and PCI to SATA bridge card.
I'm also using an external audio interface connected through Firewire.

That's it, nothing else connected at the moment. I usually have a printer and a Midi USB HUB connected and the system usually coped fine without any problems.

Previously (before the PSU gave in and before the move) I could decode a DVD or run games and the CPU wouldn't run hotter than 60-65ºC. Now it goes to 80 degrees within 5-10 minutes but immediately goes back to 40 once the task is stopped.

I haven't taken off the CPU as the fan it hard to remove and put back in and because I'm afraid that if I take it off I actually break off one of the legs. If that's the way to go I'd do that as well though.
 
Get some new thermal compound and re-seat the heatsink for the cpu, make sure to clean off the old thermal grease or compound before applying the new stuff. Just sounds like the thermal compound has dirt inbetween it after the heatsink came loose during the move, also clean the heatsink under some warm running water and remove any dust inbetween the fins and leave to dry well before reappling the new thermal compound and make sure the base of the heatsink and cpu are clean then apply the thermal compound and apply even pressure when screwing the heatsink back down.
