"The Butterfly Effect" gets a whole new meaning here: The BTF90 from ZEROtherm is an elegant joining of form and function. The butterfly shaped fins provide more than 4400cm² of surface area for cooling. That combined with the 8 copper heatpipes provide over 150W of cooling power.

The included mounting brackets make this an almost universal cooling system for Intel and AMD CPUs. Intel CPUs using an LGA 775 socket and AMD processors using the 754, 939 and AM2 sockets will all get a cooling rush.

The 92mm fan runs between 750 and 2500rpm, usually staying under 1500rpm for an ultra quiet performance. The housing free design and mag-lev bearing also contribute to the silence. And the fan has 2 red LEDs to give it sinister glow.
