[vdr] Recommendation for new hd vdr system.

For those looking for quiet fans, I have found the Nexus PWM series 
120mm to be the quietest fan for air flow yet. Moves more air then the 
Arctic fans with the same or lower noise level. I have one cooling an 
AMD x4 3ghz. I have it set to min speed of about 50% and it takes 100% 
load to get the cores up to the 40c level that it would take to trigger 
a higher speed. The fan is also clear with LED mount holes for those who 
want to fancy it up with lights.
