This is not true - moving air from a fan carries heat away more effectively than static air, so the processor can be several degrees below the ambient temperature, provided the fan and heatsink are reasonably clean. This is exactly why people use room fans in hot weather and we are given a "wind chill" factor in winter weather reports.
Wind alone just gets you to ambient faster.
I brew beer as a hobby. If ambient is a few degrees too hot, I put the fermentation bucket in larger be verage cooler bucket and fill that with water. I then setup a fan to blow across the surface of the water.
This guy didn't even use a fan, but he does use a towel to wick up the water and provide a bigger evaporation surface: http://samtierney.files.wordpress.com/2011/03/photo2.jpg
The result is evaporation of the water bath. The evaporation process sucks energy out of the bath and cools it below ambient. That in turn cools the fermentation bucket.

Thanks everybody for your input. What i like most is going from a high temperature of a cpu via wind chill to brewing beer. :) Got enough input to fine tune my machine. Cleaning of the inards and replacing the thermal compound was done on last saturday. A broken fan was replaced. There are two 8 cm fans (Noisy), one sucking air in and one at the other end of the unit blowing air out. I can live with the actual temp of 60 to 65 C. Will have to dig deeper into the details of my cpu for the max temperature. -- Linux User 183145 using KDE4 and LXDE on a Pentium IV , powered by openSUSE 13.1 (i586) Kernel: 3.13.2-14.gb59b809-default KDE Development Platform: 4.12.2 20:44pm up 9:35, 4 users, load average: 1.13, 1.17, 1.38 -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
