Ditto: with an old IBM Thinktank. With a 386 CPU - gives you an idea of the vintage - and I just took the CPU cooler out of that. It's similar in most ways to the one you photographed (but it doesn't have the additional graphics CPU cooler). And I notice that the direction of the fan exhaust is down - i.e. towards the heat source (the CPU in these instances but the cold source in the cooler design) which means the cold breeze we want to use seems to be pointing 180 degrees away from the thing we want cooled. Doesn't matter if you reverse the polarity of the motor either. Whether its pushing or sucking air, it seems to be doing so the wrong way.
