CPU temps all of a sudden rocketing

[pavlos94]

Hi all, 

 

I need some suggestions as to what might be the cause of my problem.

 

This is what I was rocking:

• Intel i7 930 (LGA 1366)
• Asus Rampage II Gene (X58)
• OCZ 6GB (3x2GB) 1600MHz DDR3
• Intel 520 120GB SSD (OS Drive)
• Seagate 1TB (contains all my documents, games, etc.)
• OCZ 600W PSU semi-modular (now replaced)
• CoolIT ECO A.L.C. CPU Cooler
• MSI HD 7970 Lighting Boosted Edition

 

I recently bought the Corsair Obsidian 350D case and EVGA Supernova G2 850W PSU (both look great!) and moved my kit over to the new case and hooked up the PSU. Once all was in, I booted it up and I was using it for 40 mins.

I then turned it back on 2 hours later and after 2 minutes the computer just switched off. I switched it back on and a BIOS warning message came up immediately saying my CPU over heated.

 

After work today I removed my cooler and reapplied new thermal paste and ensure the cooler was securely in place and booted it back up. I checked the temps as soon as I was in windows and they were at 100C so I switched my PC off straight away. When all had cooled down I checked the temps in the bios and my CPU was at ~58C and slowly rising.

 

Any ideas why? I connected a external power supply to the cooler's pump then fan and both work. I presume the pump is working as it is making some noise. 

Is my CPU bust? or could it be a faulty PSU spiking CPU voltages?

 

Please help as I don't want my PC to die!

btw there is no overclock

if you still have your stock cooler lying around, try it out

if you get more "normal" temps then it's the pump

i'll see if i can hunt it out

thanks for the reply

Yeah I found it and temperatures are relatively better now. I think my cooler had run out of water. I'm going to take it apart to have a look tonight.

 

In my new case the pump is higher up relative to the radiator so what little water was left was pooling in the radiator and not returning to the pump.
