ZEROtherm Butterfly (BTF) Series PWM Controlled CPU Coolers

ZEROtherm is a new supplier to Quiet PC but don't think ZEROtherm are young and just learning their trade. APACK, the parent company, have been supplying heatpipes and CPU coolers for the OEM market for many years. They have business relationships with many companies that will be familiar to you, Intel, Samsung and LG just to name a few.

ZEROtherm's flagship coolers the BTF90 and BTF80 are virtually identical with the only obvious difference being the material they are manufactured from. The BTF90 is full copper and the BTF80 is all aluminium. If you want the best performance then the full copper version would be ideal, but if you are concerned about the weight then the aluminium version would be recommended. Apart from weight, the difference in material also affects performance. The full copper heatsink can cope with CPU that generate up to 150W, whereas the aluminium version can handle up to 120W CPUs. This means both coolers will cope with the vast majority of CPUs available, especially Intel's Core 2 Duo CPUs.

As you can see from the image above the design of the coolers are based around the shape of a butterfly. The wings are two stacks of fins with two heatpipes that feed through each stack. Each heatpipe feed towards to the top of the cooler, is bent 180° and then feeds back through the fins. This means there are eight vertical heatpipes to help transfer the heat away from the CPU.

The supplied red LED PWM fan is attached to a red pillar that runs between the two stacks of pins. The pillar is secured in place using two screws at the top of the fins. As well as securing the fan the red pillar splits the airflow from the fan due to the triangular shape of pillar, which helps to utilise every bit of airflow produced. Apart from the also looks like the main body of a butterfly, along with two antennae!! What more do you want from a CPU Cooler?
