PEP66 from Alpha is what I like to call a different kind of cooler. The heatsink is made using the same technology like the PAL6035, but the fins are not hexagonal and the dimensions are also bigger. The same cooper base and high design quality. What makes this cooler special is the position of the fan, on one side of the heatsink.

Unfortunately we were not able to test the cooler keeping the fan in this position because this design didn't fit the K7T Limited Edition design. In fact this design doesn't fit a lot of motherboards, but we found a way to test the cooler, although a performance drop may apply. We took the cover from PAL6035 and inserted it in the cover of the heatsink. After this we screwed the same 7K Ys-Tech fan on the top. Not very hard we got a traditional high performance cooler.

The clip is the same used by PAL6035, so you won't have any problems because it's a very good one.

Although this cooler was not tested in the manufacturer conditions, we discovered that even with an on top fan it is a very powerful solution, in fact it succeeded to outperform PAL6035 with one degree in a lower ambient temperature. In normal conditions I expect for a performance with 2-3 degrees better due to the tunnel effect created by the on side fan. With the YS-Tech fan this was quite a noisy solution, but this is certainly a cooler for overclockers. The noise level was a little bit lower for PEP66, due to its taller design.

We have no word about the CPUs which can be used with Alpha coolers, but based on my experience with PAL6035 and PEP66 you can use all the AMD CPUs currently on the market, while overclocking.

A fully recommended cooler especially if you have a motherboard able to suit to its design. You have to pay, but the price / performance ratio is very good.
