A Closer Look

The BTF92 uses Zerotherm's classic "Butterfly" design. The fins, the base and the heatpipes are all made out of copper. There are four sets of heatpipes that start at the base, go up, loop around and come back down to the base for an effective eight pipes all together.


When removed from the package, the BTF92 will have a plastic film over the base to protect it. Upon removing the film the base can be seen to have some minor rippling as a result of the milling process. The base is almost flat, with a slightly convex shape.


There are 46 copper fins on each side of the cooler, for a total of 92 fins. The fins are very thin and they are prone to bending. As seen in the second picture above, there are several bent fins along the tips at the front of the cooler. This is probably either a result of shipping or perhaps a slightly under-protective package. However, it is possible to bend all the fins back into shape if the user is willing to take the time.


The fan used on the BTF92 is a proprietary one that slides into a groove on the plastic separator for the fins. The fan includes a 3-pin connector for use with motherboard headers or the included fan controller. There are even a couple small blue LED lights to give the fan a cool glow.
