<< Had a couple thoughts while digging around in there... >> The job of the small fan near the Peltier is to increase local air circulation around the CPU subsystem and to transfer the that heat into the 9150's general air circulation. The job of the PSU's fan is to withdraw all of the heat in the general air circulation by creating a negative pressure on the input side of the PSU's fan, and a positive pressure on the output side of the PSU's fan. This also accomplishes cooling the PSU itself. Reversing the PSU fan's direction would likely compromise every subsystem's cooling efficiency but most particularly the CPU subsystem ... which is the one that appears to be under-engineered. I'd try increasing the flow rate of the PSU's fan before I tried reversing its flow. -- Quadlist is sponsored by <http://lowendmac.com/> and...
