SP94 performance idle temp question ...

I think there may be cooling issue with my sp94. Please help with any suggestions/comments .

Am running a p2.8 on an IC7-G mobo. Case temp in both scenarios below ~ 30C

Previous setup: intel stock hsf with thermal pad
idle temp: 45C
under load (prime95 torture): 64/65C

Replaced today with: SP94, 92mm acoustifan with arctic silver 5.
idle temp: 45C - Exactly the same as my stock HSF
Under load (prime95 torture): 59C

I expected to see my cpu idle and load temps to be lower than the results show.

Please help with any suggestions you might have.

What's the CFM rating on that fan of yours?

-AMD Athlon64 3200+@2300mhz -GAK8N -3x512 Hynix PC3200 ram@192mhz 2.5-3-3-7 -Albatron 5900PV @ 560/1000 -SB Audigy -Adaptec 1210SA Raid -2x120G Seagate SATA150 7200.7 Raid0 -Enermax 460watt psu

~42CFM at 12V at 2K rpm - currently set to receive 12V

Does the orientation of this particular heatsink make a difference? It only mounts in one direction - horizontal.

It is currently mounted with the heatpipe on the left (ie: closer to the peripheral adapters - mouse, keyboard etc)

You're using MBM5 right?

Is your fan pointing down? I know its a silly question, but it should be. Also, I'd try a higher-cfm'ed fan - the Thermalright heatsinks are great with high cfm fans and not so great with lower ones (seems like your fan pushing 42cfm at 2k rpm is going to be quite low on air pressure, which is important when cooling the fins of such a restrictive design heatsink).

Most of what im going to say Duh stuff but you never know.Try taking the heatsink off and clean off all thermal paste or tape that might left on.Make sure its totally clean and make sure that you removed the plastic flim that comes on the heatsink.Basicly just make sure you installed it right. 3d game man has a video guide on how to install it heres a link.<A HREF="http://www.3dgameman.com/vr/thermalright/sp94_heatsink/..." target="_new">http://www.3dgameman.com/vr/thermalright/sp94_heatsink/...;/A>

Go to the Abit website, and go to the forums. The IC7 series of mobos read temps really high, usually in the range of 7 to 10C high.
