Sudden CPU Temperature rise.

I fitted a Q9650 to my system along with a new Corsair H80 cooler about a week ago and OC'd it to 3.6Ghz and got temps of around 49c when gaming and about 30c at idle.
When i turned my PC on this evening and did a bit of gaming i got the BSOD so restarted the PC and noticed that the Core Temp tool was showing temps of about 48c at idle and about 65c during gaming.

Why the sudden rise in temperatures? all the fans are working.

Thanks.
 
Could be the ambient temperature.

Could be the block was not seated properly (unlikely)

What setting are you running the H80? I mean what speed?
 
is the water pump connected to the correct port? I plugged my H70 into the cpu connector on motherboard and it didnt pump the water round enough, i needed to plug it direct into the 12v connector on power pack and use the motherboard ports for the fans
 
The water pump yes as it runs at full power as its supposed to , but if you plug the fans into the psu, then they will be running at full 24/7 so when your idling it will be noisy. I'd plug the fans into the CPU fan port on motherboard. You can set them to auto or manual in the bios. I used to see my CPU in the 50's and 60's under load but sine I've updated the bios it's always in the 30's
 
Cheers, i'll plug it into the psu then as it's the antec kuhler and it's just the one plug as the fan and pump connects together
 
Thanks everyone. I have connected the Molex connector and connected the fans to the pump block and set them for full speed.

The strange thing is now my idle temps are between 20c and 26c with no overclock which is about a 15c reduction compared to yesterdays temps also with no overclock.

Also what is the other connector for on the pump, it has a single wire with a 3 pin plug which i assume would go to the motherboard CPU fan connector but what would this do, ie would it show the fans RPM or the pump RPM.

BTW all the fans in my system are working.

Thanks.
 
Is the extra lead to monitor the fan speed? Them temps are correct now. As its high performance cooler. I think the stock cooler keeps it at 30degrees with no overclock
 
the pump RPM should be around 2000rpm with fluctuation -/+ at 10%
also is the pump seated the right way i.e pipes coming out the right side or left if been fitted the other way as if the pump another way and you bolt it down some boards have the caps right near the cpu socket and that lifts the pump i.e not seated correct. it is not completely square as well i think it is 50mmx65mm base.
 
How do i monitor the pump RPM? is that what the extra lead wit a single wire is for?

Here are my temps taken after heavy gaming before it had chance to cool down to idle temps.
Seems to have stabilised now. These temps are with the cpu running at 3.6Ghz.

there is a 3 pin plug (single wire) that is on the molex lead, plug that in the cpu 3 pin plug as that sensors the Pump rpm, or any convenient 3 pin header that sense's Rpm's.

use AIDA64 or something similar to monitor the Rpm's.
 
no problem , but i would leave the fans and put it on balanced , the performance of the supplied fans you will never replace just due to the static presser , what you can add to the H80 is a shroud or two as the middle of the fan is a dead spot.

you can buy a 31mm frame fesser xtender there dear but look good or cut out an old fan, around 30mm is the sweet spot but if not 25mm frame will do.
