In this day and age, most of the CPU coolers on the market are almost identical. The introduction of the heatpipe really closed the gaps in the market for one company to have a superior cooler. So, what companies like ZEROtherm have done is to create some sort of flair with the shape of the actual cooler to attract the attention of the customer: in the case of the BTF90, which is a butterfly design. Don't let this shape fool you - every turn or notch actually creates a larger surface area, and we all know that a larger surface area cools an object more efficiently. Each wing of the butterfly is its own separate cooler with a plastic divider down the middle, thus giving you four heatpipes in each wing. Let's see how well this cooler flies and get on with the review.

Now it's time to get a closer look at the BTF90 CPU cooler itself. The BTF90 is constructed from copper. The fins, heatpipes, and base are all copper, and with the materials being the same, the heat transfer between them will be consistent. Although the fins of the BTF90 are shaped like butterfly wings, this weighs a ton - so don't drop it on your toe. Four heatpipes bent into a U shape create a total of eight pipes. These heatpipes are sandwiched between the copper base and an upper plate that is silver. Two sets of 46 fins make up the left and right half of the wings. A plastic fan bracket separates the two sides, thus giving you two separate cooling areas.

The fan on the BTF90 is a 6 bladed, clear acrylic fan, illuminated by two red LED's. Yes, I said red and not the run of the mill blue LED's. You will see that it is recessed into the fins of the cooler. The fan is designed with Silent UFO technology - which stands for Ultra maglev Forms Oil protection bearing fan - and Automatic PWM fan speed control, with speeds ranging from 750 to 2500 RPM with the average speed being under 1500 RPM.
