nPowerTek TTIC NPH-1 Heatpipe Heatsink Review
nPowerTek TTIC NPH-1 Heatpipe Heatsink Review
  95%   
Abstract: The heatsink looks fairly unremarkable from the outside, but at the center sits a 25mm diameter copper heatpipe which gives the NPH-1 some really serious kick.

Home > Reviews > Page Title: Acoustic Samples: Listen to this Heatsink!

The two fans generate a bit of noise under power, and would probably be noticeable from outside of the case. The whine isn't particularly high pitched however. To listen to this heatsink for yourself in operation, be sure to click on the little headphones icon below and download the Acoustic Sample MP3 file.

Sound Level Measurements:

Listening to the actual noise a heatsink makes allows you to hear what pure numbers alone cannot get across. To further emphasize FrostyTech's reliance on cold hard facts when evaluating a heatsink, we also take Decibel readings with a sound level meter. These results may be higher than the manufacturer's listed specs, but then again these are real world measurements. Measurements are made on the dB (A) scale.

The noise levels of the NPH-1 under power were measured to 52.3 dB. There are plenty of quieter heatsinks out there, but the pitch and whine of the fans isn't all that distracting. Plus as we're about to see, it is possible to run the nPowertek's fans at a lower RPM for near silent operation...
