Rbmods posted a review on the Evercool Serpent Northbridge Chip Cooler

One of the main problems with various motherboard's northbridge cooler is the small heatsink with little fan at 5000rpm. Fan at such speed makes high noise making use of computer very uncomfortable, not to mention the situation where the fan stops at all making the northbridge to overheat and possibly break due to it. Evercool was kind enough to provide us their newest northbridge cooler called Serpent.
