New Q9550 - temp issues

I have left my q9550 stock for the time being as just upgraded from a 0 airflow case to the haf 932 so not began playing yet.

Under full load (prime95) cores highs have hit 58 53 57 56, while on idle i get 36 33 36 36 respectively - ambient was 20c. The heatsink+fan combo is thermalright hr-01 plus + noctua nf-p12 running at 12v. Update to this test, same ambient and using intel burn test with error detection and full test x 5 hit 68 63 63 68, so a full 10c hotter than prime95 could manage.

My vid is running below 1.25 and the processor drops down mhz when idle, ie multiplier goes from 8.5 to 6 (cannot remember which bios setting stop this )

I think its C1E you need to disable and any Intel Speed Step settings if you want your cpu to run at full speed all of the time.

With an ambient of 20 that seems hot (unsure if its OK) - I get less max temps in a hotter room on the burn in test and that is overclocked to 3.4 with 1.2 volts.

It does seem a bit hot however the heatsink has been in and out a few times so not redone the AS5 (ran out) and my coolermaster V8 should be here today or tom so will redo the temps with my new AS5 tube that I found last night

Could you post the temps when you have redone the HSF please?

No probs, will prob be at the weekend if our son goes to sleep

I have overclocked the cpu to 3.4 and it passes the intel burn in test. The max temp hits 67 (67, 67, 62, 61) degrees in a warm room but the system is stable.

My case is ancient though so airflow could be better. Antec 300 maybe?

I have the same OC and the Antec 300 case... it's a bit cramped in there really, and hence prob not the best for cooling. I'm looking to upgrade to something a bit bigger, maybe the Antec 902

i had an Antec 300 delivered today but am not happy with the quality.

V8 Results are in.....

Ambient of 20c

Idle - 36 33 32 34 (previous 36 33 36 36)

Load - 59 56 56 59 (previous 68 63 63 68)

So idle temps are about the same, if not a few c cooler on some cores, on full load with intel burn test made a 9c difference on cores 0 & 3 and a 7c difference on cores 1 & 2.

BTW all these test were carried out using the slowest fan speed of the v8, currently 1300rpm (ish)

Now this is where the comparison to the thermalright falls down, upon taking the old heatsink off found there to be no paste in the centre, eg you could read the chip markings, just paste around the edges - what was I thinking of when installing it :confused:

.

Install of the v8 was easy took about 45 mins including removing and cleaning the old one. Did not take the mobo out for the install just held the v8 in place while reaching round with the other hand to screw it down on the back bracket. Also did not use the AS5 but instead used the sample of ThermalFusion 400 paste that came with it - if I come to remove it for any reason then will try the AS5 instead.

Not bad highs and lows. My lowest core gets to 26 on idle and max is on 66 on intel burn in test.
