Extended overclock sessions versus temperatures

Extended overclock sessions versus temperatures

Since we have such high-end cooling in the house we definitely should have better tweakability on the processor.

As such I was wondering where I'd end up with a quick overclock session. We had a peek at a selection of stages in overclocking and their respective temperatures, have a look at the following results please.

Temperatures in Degrees Celsius

Okay so these are the tested stages, above the Core i7 870 @ default / 3.2 (1.3V) / 3.8 (1.4V) /4.2 (1.5V) GHz. So even at 3800 MHz with 1.4 volts we can use the processor with this cooler, though we are rapidly closing in on maximum temperatures.

For the sake of it we also used two fans in push-pull mode offering better temperatures (at the cost of more noise). It does improve the overall cooling performance quite a bit.

What we can conclude here is that the thermal dissipation, or even better stated, the cooling capacity under high stress, is reasonable at best. This cooler has only  decent capacity for the most stringent overclock setups.

We are borderline with temperatures at 4200 MHz / 1.5 Volts alright.
