Fun with testing

Going for a higher overclock and am running P95 right now. Got a bad OC so had to reset the CMOS, then started test with the side of the case open. Recorded temperatures after 15 minutes then added side back to case and recorded temps after another 15 minutes. Running two instances of P95 to really work the HT on my prescott. Currently overclocked to 3.9ghz on 1.4v with 5:4 fsb.

Got some interesting temperature results verifying my plan to add another intake fan.

Temperatures are taken from -

CPU and Chipset: SpeedFan
Case Temp: Cooldrive 6 - Sensor floating free above RAM.
GPU: nVidia control panel

Rig in sig.

Fans settings:
Zalman 7000b AlCu @ 2596rpm
Zalman vf700 Cu @ 1600rpm (lowwwwww)
1x80mm Vantec Stealth front @ 2130rpm
1x92mm Zalman FB123 rear @ 2010rpm

Case open:
45-46c chipset
56c cpu
45c gpu
35c case

Case closed:
44c chipset
60c cpu
50c gpu
32c case

This is a good example of:

a) The benefits of open air for active cooling: with a constant supply of fresh air, the components with fans stay much cooler.
b) The benefits of closed case for passive cooling: With focused airflow through the case, passive heatsinks receive more airflow over them creating better convection.

What this means for me is that I'm going to get a holesaw and add a side fan for another intake. I always knew I needed another intake but couldn't decide whether to add to front of case or side. Also I need better ram so I can overclock using 1:1 fsb.

Have a good day!
