360° View - Thermaltake Venus 12 Heatsink Information on Frostytech's test methodology is available here.
	The Heatsink Fan: When this three-bladed impeller rotates at its full 5500RPM, it is the definition of a 'finger chopper.' Selling the Thermaltake Venus 12 without a fan grill of any kind is just dangerous... and bloody fingers everywhere will attest to that. Noise levels range from near silent to utterly obscene (~68 dBA). Power comes from a standard molex connector, and a single RPM signal cable supplies data to the motherboard fan header. The fan has a 2-pin thermistor sensor connector and a 2-pin connector for a fan rheostat which can both control rotational speed.
	Heatsink Top: The 73 stacked copper fins overhang the copper base they are soldered to along one side. Each 38mm wide fin connects to 27mm of surface at the base. The fan support has mounting holes for 80mm and 70mm fans so users have the option of installing different sized fans. The support also creates a 5mm plenum above the copper fins to promote more even airflow.
	Heatsink Side A: The copper base of the Thermaltake Venus 12 measures 5mm thick. The stacked copper fins are soldered to the copper base plate. Each fin measures ~0.1mm thick and spaced 1.0mm from the next.
	Heatsink Side B: A tool free clip mechanism used on this heatsink. Once all three metal tabs are locked into the K8 retention frame, rotating the cam arm applies the necessary force and locks in place.
	Heatsink Base: The 66x73mm copper base has a sanded finish which translates into a surface roughness of ~32 microinches. The base surface is pretty flat.
