lower rpms = lower temps?
Last night before bed, I went to turn down my 80mm SF2 using Abit's FanEQ thing. At full blast (5000+ rpm) my cpu temp was at 36C. I turned down the fan to about 3700rpm and my cpu dropped to 34C.
So faster (more cfm) is not better? It seems like everything I thought I knew, I don't. Would a 60mm low rpm fan cool even better?
What is the ideal fan size, rpm, cfm for a slk-948u? My cpu is a p4 2.8 @ 3.2.
Oh yeah and this isn't an april fool's joke to get all of you to turn down your hs fans and melt your cpu's! I just want to know what some other people's temps are with similar systems. Thanks.

Maybe at the higher speed it was generating turbulence and backpressure, resulting in lower airflow.
SLK-947U w/ Tt SF2
EDIT: Forgot the temps.
CPU idling
55 degrees @ 3700 RPM
51 degrees @ 5000 RPM
The reason i haven't is b/c i have 4 hdds at the front of my kingwin kt-404 case, and 2 80mm front intake fans blowing directly on them. If i switch intake/outake, i don't think my hdd's will keep cool.
But if i get motivated, i will switch it around just for a quick test run. Any body have dramitic results from reversing airflow?
