Here's my h100i results after nearly 24hr of prime95 blend with 7 threads (it hit 73C in the first hour though, look at Real Temp's readouts) @ 4.6 Ghz and 1.376V (fluctuated due to offset voltage):
it really was only doing 7 threads for some reason. I posted a question regarding it way back when.
Here's my h220 results after 1 hour of prime95 blend @ 4.5 and 1.368V (fluctuated due to offset) w/ 8 Threads:
I can re-test again at 4.6 later just for testing sake.
with this particular mobo and temp sensor readout, sub 70C overclocked at load is impressive. My friend who sold me this rig and used it with an h100(non i) always got above 70.
