360° View - nPowerTek NPH 775-1 Heatsink Information on Frostytech's test methodology is available here.
	The Heatsink Fan: Looking at the top of the nPowertek NPH 775-1 heatsink the top of the 25mm diameter heat column is visible. The anodized aluminum fan shroud is constructed with 1mm thick aluminum sheet metal, it holds the 80mm fan in place and has space for a second too. The fan is powered by a standard 3-pin fan header which supports RPM monitoring.
	Heatsink Top: The 80mm fan blows it cool air across the copper fins and around the heat column which ranges from top to bottom of the nPowertek NPH 775-1 heatsink. Since the sides of the heatsink are left open, there is little problem with back pressure.
	Heatsink Side A: From this angle we can get a better view of how the 80mm fan is positioned with respect to the 25mm diameter heat column that extends the height of the cooler. Since the sides of the nPowertek NPH 775-1 heatsink are open, air can move in and out of the unit as pressure dictates. The bottom 25mm heat column has no cooling fins so there is adequate clearance for the clip and mounting hardware. The copper fins are 0.2mm thick and spaced about 1.5mm apart.
	Heatsink Side B: The nPowertek NPH 775-1 heatsink uses captive spring tensioned screws that mount to a rear motherboard support plate. For this you'll first have to remove the motherboard, add the rear plate, and then install the heatsink. The screws each have a compression spring which applies the correct amount of force under load, so the NPH 775-1 rests evenly upon the processor. Installation will require removing the motherboard from the chassis, and a phillips screwdriver.
	Heatsink Base: A 31mm copper base makes direct contact with the processor's integrated heatspreader. This disk of copper is the base of the heat column, so there are no other thermal joints between the CPU and component which transfers heat energy throughout the rest of the cooler. The base is machined flat, and very smooth. Surface roughness is equivalent to about 16 microinches, which is considered very good. An aluminum frame is used to attach the NPH 775-1 heatsink to a threaded socket 775 rear metal support bracket.
