Frostytech has published a review of a new low profile heatsink that could be really great for SFF PCs or media center's without a lot of room to spare. Be sure to check out the thermolab micro silencer review.

"In this review Frostytech will be testing a low profile Intel socket 775 heatsink which could be ideal for 2U sized server chassis, small formfactor PCs and other media center microATX-style cases which are seriously height limited. The Thermolab Micro Silencer TLI-S heatsink uses a simple swagged aluminum fin and heatpipe construction, weighs a feathery 276 grams and comes with a pre-applied patch of 8 W/mK rated gray thermal interface material."
