The Spire Fourier IV is a new approach for CPU coolers. At first, it looks and feels big with a rather unusual design. The four copper pipelines, promise to do an excellent job transferring the heat away from the CPU, which was confirmed by our tests. In general, the Spire Fourier IV (at full speed) managed to keep the CPU's temperature almost 10°C lower than Intel's stock fan. Under full load, the difference was even greater, and reached 17.5°C. Very impressive.

The installation procedure is a little tricky, but shouldn't worry most users. It's simply different to what you been used to with Intel's stock fans. It uses four screws to mount, so you think twice before removing it, but at a retail price of US$42, the package delivers good performance. You can now overclock your system to new heights with the Spire Fourier IV air cooler...
