Need some help

At the begining of the year i got myself a nice new gaming rig:

Intel i5 2500k
Asus p8p67 pro ver B
Nvidia GTX 570
HAF X
Corsair H-70
4GB corsair XMS3 PC3-10666

It has worked great all year but recently it randomly seems to overheat, and by randomly i mean it will work great for say 5 days then for a few hours on the 6th day it will keep overheating and then go back to working great for a while.

Only thing i could imagin it being is the pump on the H-70 but would it really just fail at random like this? or maybe the sensers on the mobo are off i really don't know. Really just looking for some input on this or if anyone else has had this same problem. thanks

If it's a spontaneous as you are suggesting it does seem like the pump may be failing occasionally but it sounds more like a power issue rather than the pump as the pump would either work or not. Try connecting the pump to another power source and check the voltages to make sure they are stable on both idle and load conditions.

I originally had the pump connected to the CPU fan slot on the mobo but have now connected it to the PSU this morning but it's still happening.

one thing i missed from my op is that it only seems to occure after the system has been off, i am yet to have it happen while the system is crrently running.

using the Asus tools my idle temp is usually about 25 - 30 degrees c but at the moment it seems to be idling at about 60 and shoots up as soon as i do anything untill the system crashes.

Double check the PSU. You can use my guide here:

Check also the connector on the pump is sound and isn't shorting.

Lastly, can you revert to a standard air cooled HSF? If this sorts out the problem then it would confirm the pump has indeed failed.

the link doesn't work.

after having my pc off for about an hour it seems to be working now, current temp is 30 degrees C while playing Star Wars The Old Republic. it has been sujested to me that it could be the thermal compound thats the issue? would that cause such a random issue?

i should have the stock HSF somewere i could try that though i am currently out of thermal compund and don't really want to head to some poor local store to get some cheap stuff

Edit: i moved the pump from the PSU to the power fan socket on the mobo as i was told that always gives 12v and the asus tools are showing the pump as running at 1400-1500 rpm is this normal? earlier on when it was connected to the CPU 3pin it showed as running at 5000RPM not sure why they were so different.
