flash doesnt get the cpu to reach 70.. i will get in the 60s but it mostly stay in the 50s.. i get 70 fron a fractal benchmark that use 4 cores at 100% ... but still flash video.. will get the fans to speedup at around 2000+ rpms wich is kind of loud compared to my older g5 dp mac... i guess there is not much to do unless i try to dissemble the lcs for inspection..
