To anybody who's been in the market for a reliable HTPC CPU cooler that'll fit in a 2U case, I feel your pain. It's near impossible to find a quality heatsink that's less than 3.5" in height; this is where the AXP-140 steps in. Topping in at around 2.9", Thermalright has done a great job designing the heatsink for maximum heat dissipation with high volume restrictions.
