The first thing that will strike you about this cooler is its size. It stands 150mm tall, so make sure it will fit inside your system. For the record only the Scythe Infinity and the Thermalright IFX-14 stand taller than this cooler, but the Nirvana looks more compact than the two for mentioned CPU coolers due to the fact the 120mm fan is built into the body of the Nirvana.

Gone are the references to butterflies and in are references to bees! We say this because the heatsink features a Honeycomb Structure. This feature increases air pressure at the centre of the heatsink to aid cooling, and boy does it work! During our evaluation no matter what we tried we could not get our Intel QX6600 Quad Core CPU over 41° and this was with the fan speed on its absolute minimum. Not only does the Honeycomb Structure help but also the copper base and the four U-shaped copper heatsinks play a massive factor. They transfer the heat quickly and efficiently into the fins where everything is cooled by an extremely quiet fan. Compatibility and Installation

The Nirvana is compatible with Intel's LGA775 and AMD's 939, 940 and AM2 sockets. Installation is extremely easy. The images below show the two different brackets required to mount the cooler depending whether you have an Intel or AMD system. The AMD bracket will just attach to the supplied black retention module currently around the CPU. Unfortunately it is not that easy with the Intel socket. The motherboard requires the supplied backplate installing and once it is done the cooler simply screws through the motherboard and into the backplate.
