I am quite surprised by Cooler Master and their new retail products. Not only these products show the usual CM quality, but even more, they have a very nice package with everything you need. The PTK especially impressed me because it managed to stand against the AS3, and, although not perform as good, still holds some other advantages that are equally important, like no electrical conductivity. The PTK-001 doesn't need a burn-in period, you just put it on your CPU/GPU or whatever and that's it.
