No no no, I bought a WW for myself , when it was $65 no less, and it was as I described in my previous post. I then built a water cooled system for my cousin and decided I'd give them a second chance, big mistake. The TC-4 they sent me leaked like faucet, I had to pull both the fittings out and seal the threads with RTV to make it stop leaking. Then, I had also bought the rad and shroud from them too, when I went to test it, it leaked around the fittings on it too. Not to mention the fins were all bent up on it. So, as you can see, I haven't had a real good track record with DTEK. I know the newer blocks are supposed to be much better, but I think we all know the quality of Cathar's work is second to none. Even if there is little or no difference in performance, I'd still take an original LRWW any day.
