Either that or the new heatsink that Noctua has. They did some benchmarks on it and it cools just as well as the TRUE does, PLUS it comes with the Noctua fan for the same price as the TRUE by itself. If you add an extra fan to the Noctua ( it can do push + pull ) it's even better than the TRUE.
I lapped my TRUE + 1 Noctua fan and I get around 31c core idle and around 45c core load ( core temps are about 4c higher than the CPU temps ) running prime on all 4 cores.
Funny thing is my computer gets real unstable beyond 2.8ghz. Vista just locks up randomly for no reason. It will run prime fine for hours but lock on stupid things like Firefox
