Yes, but the thing about overclocking is that you always want more .... I'm running mine at the total limit - 75c under load and i'm still not happy. The next step for me however is a £200 watercooling setup. The TT is like £30, which is a small price to pay for a solid overclock. I guess it depends on how serious you are, but i would rather just buy something good and get it over with.
and that cools your northbridge and graphics card as well. A bargain at that price IMO
