Since no1 wanted to buy my old zalman model i decided to mess around with it and i found a way to attach a fan to the side. What makes this better is you can use any fan you want instead of that dinky optional zalman fan. It could even be a 120mm fan. What you do is use longer screws for the fan and zip tie those to the side of the top heatsink (side facing up) via the fins pointing out. So for those who have the A model and need some better cooling, this is a nice, easy, and pretty much fool proof mod to transform it into essentially the C model. For those who dont even have this cooler and dont care what i have to say
