The huge size of the Alpha results from a big, slow moving fan. Like the Swiftech model it has a body put together of single aluminum pins. Therefore, it has a big surface that absorbs the heat effectively. Due to its cooling performance of 40 degrees Celsius in our test, this cooler is number 4. The installation is a bit difficult as the mounting brackets sit very firmly.
The powerful Alpha PEP66T needs a lot of space on the motherboard.
