So what's so different about the PCH075? Its looks and its design of course. The PCH075 includes 3 layers; the inner core has a copper layer at the base surrounded by a larger aluminium core. The copper base will be the key to the effectiveness of this cooler. Thereafter two more aluminium layers overlaps one after the other. Keeping the diameter of the lower part of the cooler as narrow as possible the PCH075 has no problem is fitting into any mainboard. (it's narrower than the Mini Orb by far). The cooler itself is fairly large spanning at 62x62.

What catches your eye the most of this cooler is the oversized cooling fan. Measuring at 70mm this is by far the largest cooling fan out of all the above coolers. Sadly however its size does not correlate to the fan's performance. Spinning at 5000RPM and producing a total of only 27CFM this isn't the ideal cooling fan for extreme overclocking. The fan doesn't look like the everyday cooling fans you come across. The fan blades are spanned in two rows giving the impression to two fans; only if it performed equally as well. Since its slow spinning speed the noise produced by the fan is quite low, in fact in contrast to those mighty Delta fans this could be considered a whisper.

Installation

In addition to the normal clip we see in most coolers the PCH075 also uses a special locking mechanism to lock the CPU in place. This makes installing the PCH075 an effortless procedure. Simply place the cooler over the CPU and turn the locking lever. There's absolutely no pressure on the CPU at all. It's in fact much better than the compression clips of the MC370-OA. Full marks to Powercooler for this special mechanism.

Testing 

Conclusion

Well the results aren't too bad considering the cooling fan pumps in only 27CFM. You could install a Delta fan if you wish, and I'm sure the results would be much better. Why should you go for the PCH075? Well for one it looks darn cool, and its performance isn't that bad either. In comparison to most of the coolers looked here the PCH075 could be considered only as a mediocre performer. Nevertheless taking all aspects of the cooler into consideration I'm quite satisfied with it. Lets hope Powercooler revises the PCH075 with a better cooling fan, which will no doubt give this cooler a force to recon with.
