The base is the bottom of the heatpipe core and appears well finished:

Mounting requires removing the motherboard from the case to secure the heatsink to the back mounting plate.

Performance Test

The NPH 775-115 was tested on an Asus P5WD2 motherboard with a modified Pentium D 805 to read CPU case temps while running Prime 95.

²50 dBA measured 8″ from the fan intake corresponds to about 30 dBA measured 3 feet from the fan, a very quiet noise level.

Performance was quite good and ranked in the upper third of heatsinks tested to date HERE – it should be suitable for mildly aggressive cooling with low fan noise.

Thanks again to nPowertek for sending this our way to test out.
