Subject: 	Re: Small heat sinks for 128D

I should've been more specific, this is a metal case 128D aka 128DCR.   
I believe the plastic case 128D did ship with a fan.  There is a vent  
at the back of the chassis where the integrated power supply fan would  
have been were one included, and there are vents in the front allowing  
a front to back airflow.  There are even screw holes for where the fan  
would be mounted were it included.  I do not see a pin header or holes  
in the power supply PCB for where it would attach, so I was hoping  
someone else had done some reliability modifications along these lines  
and could recommend a fan and a minimally intrusive way of powering it.

I'd like to add heat sinks to the chips that get hot in combination  
with the fan given the age of the hardware and my intent to have it on  
a high duty cycle.
