Hi to everyone I am new here although I have been reading Custom PC for over a year. Last month I bought a Warbird i750x upgraded to 1TB Samsung and xfx 5850. Everything has been working fine except for the dvd drive connector had come out during transport, which I found and replaced. But last night I decided to run a Prime95 stress test I let it run for just over 2 hours with no errors but core temp on the cores was between 86c and 92c. When the machine is idle it runs at 48c to 49c and in the mid 70c when playing Crysis is this ok for a machine yoyotech overclocked to 4ghz or should I be worried. I have had no problems with the machine what so ever.
