The good guys at nPowertek were nice enough to send a sample of their NPH 775-140 HC heatsink. This features 104 aluminum fins with a 33 mm copper heatpipe core.

Key Features

  • Aluminum fin construction with copper core heatpipe
  • Dimension 92 x 75 mm
  • 92 mm Fan, speed 3000 rpm, four pin molex connector
  • Weight ~400 grams
  • Supports all Intel® Socket LGA 775 CPU

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

Mounting is very simple – the heatsink is secured to the motherboard with four push-pins. This system does not require removing the motherboard from the case.

Performance Test

The NPH 775-140 was tested on an Asus P5WD2 motherboard with a modified Pentium D 805 to read CPU case temps while running Prime 95.

¹On-die temperatures.
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 placed this heatsink in the lower range of heatsinks tested HERE; the noise level was moderate but not objectionable – just noticeable.

CONCLUSIONS

Overall not for aggressive cooling – an OK heatsink for an OEM CPU for 4 pin systems.

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