I tested and posted somewhere earlier in this thread my Extreme with the waterblock (not hooked up) and big ugly cooler out the back, on versus off. My IOH "NB" temps were 55-56C max load without the big ugly cooler and WB and 54C load with the big ugly cooler and WB (no water). So it makes ~1-2C difference. Idle was 47-48C either way. Even sticking a 120mm fan up against the big ugly cooler only decreased temps another 1C.
Taking it all off and putting a tricool spot fan hitting IOH...IOH temp now load 47-48C max. But whether 48C, 54C, 56C, overclocking it makes no difference whatsoever.
