Cross FloW fan specs by Cooler master

45CFM rated at 38dBA

their own 120mm fan rated at 16dBA @ 1200rpm which is the same speed my Papst is running; the Papst 120mm pushes 40CFM

now I don't need to tell you how much a difference 16<>38dBA IS? both are rated by Coolermaster; in short; it's HELLA LOUD, and does not move a lot of air. 2 silent 120mm fans move DOUBLE the air

5°C off the chipset temperature is not quite worth the noise; does it decrease CPU temp?

you can put it at medium, so you hear it a bit, the biggest noise is that of my chipset
i am searching for some heatpipe solution for that like the new abit-boards

jmke, it sure feels like a lot more then 45CFM, it has a great impact on my ram/chipset cooling
altough it was quite expensive
but i like it, imo its worth the cost, mem doesnt get that hot anymore

i dont know about cpu-temp, will test it when i got the temp-sensors from piotke + big typhoon + new graphic card (i dont have one atm)

2*120mm aerocool :

RPM 1500rpm
Air Flow 59.12cfm
Noise Level 29.58dba

2*120mm papst 4412 FGL:

Vitesse de rotation : 1600 RPM
Ventilation : 55,3 CFM
Niveau Sonore : 26 db(A)

I don't think i've to worry about noise :)

a crossflow fn doesn't exhause rotating air, that might help giving a more direct airflow.

My keyboard

End of this week I should be getting the rest of my watersetup.
Still don't know if i am going to use silicone tubing or dangerden tubes.
Also ordered a x2 3800+, dfi ultra-d , 7800gt for a friend which i can test for a few days.

my keyboard:

Bit to expensive for me :)

Perhaps, we could compare OCing/performance with my newly yet to arrive Opteron 165;)

Your water cool versus my cheap air cooling.

Yes we could, got boxed aircooling and 2 watersetups.
But you got 2mb cache so you get better results on stock.
Got also a opteron 146 which i can compare with.

I test with regular Win XP pro + sp2. (superpi - 3d01-03-05 - sisoft and maybe some more)

let the games begin!

only CPU dependant benchmarks (of course) as you don't have the same video cards!
