Here are some pictures of a recent hardware addition to my PC. It is a massive heat pipe based Tuniq Tower 120 with a 12 cm fan hiding inside the heatsink. Due to a combination of its size and the mounting bracket the install was not the easiest I have ever done. It was well worth the minor hassle.
The Intel E6600 sitting below the behemoth has a default clock of 2.4 GHz. It now reaches 3.5 GHz. If I have some time to kill I will try and tweak it some more to get some extra Hz. For everyday usage it runs at 3 GHz with all my fans set to the slowest possible fan setting. This keeps my office from sounding like a wind tunnel.
