Zalman recently launched a new low-profile cooler by the name of
CNPS8000. Physically it looks to have a lot of potential; It's a great
looking product overall. Included is a fan speed controller for when you
feel the need for an extra punch. Sadly, in our testing we have found
even with that extra cooling ability, this cooler falls short.
