Scythe Infinity stock 46.5cfm vs TT 81cfm vs Delta 190cfm results

[eva2000]

I decided to use my power hungry 955XE cpu rated at 130 watts for testing some power supplies I have been sent. But since, i'm planning to take apart my water cooling setup for a clean etc, I will go back to air cooling for cpu for the time being.

I'm going to use a Scythe Infinity heatsink which arrived today. I'll play with 3 fan configurations

1. Stock 120x25mm 46.5cfm 0.13amp fan
2. Thermaltake 120x25mm 81cfm 0.40amp fan http://www.thermaltake.com/product/D...2003/a2003.asp
3. Delta 120x38mm 190cfm 3.0amp fan - http://www.xtremesystems.org/forums/...77#post1779677

Notes:
I noticed in most pics and reviews the fan is positioned dead center of the fins with part of the fan blowing up the top of heatsink as in pic at http://www.scythe-usa.com/product/cp...1000-main.html

I have the fan so it's situated with part of fan blowing at bottom of heatsink so it cools mosfets too http://i4memory.com/reviewimages/coo...rmaltake81cfm/





System:

• Pentium D 3.46Ghz 955XE Extreme Edition (130W)
• Scythe Infinity with stock 46cfm fan (change to 120x38mm Delta 190cfm 3AMP fan later)
• Intel D975XBX Bad Axe rev304 1334 bios
• 128MB Gainward FX5200 PCI card (initial tests - change to higher end cards later)
• 3x 320GB Seagate 7200.10 SATAII hdds
• Pioneer DVD-RW Burner
• 1.44MB FDD
• 850W special psu

Just doing initial temp tests since the Scythe Infinity only arrived today and first time using this heatsink.

For those Core 2 Duo folks wondering, a 955XE @ stock 3460Mhz at 1.275v rated at 130 watts theorectically has more heat output (in terms of wattage) than a Core 2 Duo E6600 @3809Mhz at 1.511v!
