I'm sure that there are fanless PSUs out there, but because of the MOSFETs, they must have some kind of airflow. So if you don't have a PSU with a fan, then you are relying on the ventilation from within the case to keep it cool. (EDIT: unless it's an expensive PS designed that way)

If this PSU is indeed rated to 475 Watts, it will certainly require some ventilation. (EDIT: unless it's an expensive one designed that way)

Think about it this way: there's a reason why ATX PSUs have at least one fan now... Some even have three! (EDIT: some really don't have any, but cost more)


A 15'000 RPM HD does NOT require active cooling (i.e. Pelt), but does require normal case ventilation. a Seagate Cheetah's operating temperature will reach 55C. THIS IS NORMAL. (EDIT: requires ventilation such as is found in a server, since these are server drives)

So if you are not happy with simple rubber mounts, then go ahead and wrap it up in foam, and then you can incorporate a HD waterBlock. Just make sure that it cools the right side of the HD.
