The heatpipes in the base of the cooler are spaced out at 2.7mm from one another, which is quite a lot compared to Cobra cooler we have just discussed above. It may have some negative effect on the heat transfer. At the same time, the base is very even and covers the entire CPU heat-spreader:

XIGMATEK Nepartak is topped with exact same fan as Cobra: it has the same dimensions, number of blades, marking and even color. However, they claim that this fan has slightly different specs (see table below). The fan is installed onto the heatsink with shock-absorbent silicon spindles:

The XIGMATEK Nepartak installation procedure is very simple and intuitive. It installs almost the same way as Cobra cooler:

Unfortunately, the new cooler cannot be installed onto LGA1366 mainboards with the bundled retention kits.

We tested XIGMATEK Nepartak efficiency inside the system case and it proved barely dependent on the way you install it. 1-1.5°C is the most you could win by installing the cooler like this:

The interesting thing is that this cooler is priced even lower than Cobra. Its MSRP is set at $25.
