Thermalright SI-128 SE Heatsink Review
 

Thermalright combines the best of their blow-down coolers with the unique design of the high-riser series to bring us the SI-128 SE. Instead of "Second Edition" as you might think, the "S" in SE is for Silent, something their HR line of coolers was quite good at.
