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. So we popped in a Core i5 750 processor for a good reason, we had a peek at a selection of stages in overclocking and it's respective temperatures, have a look at the following results please.

Overclock results with one fan

We'll remain focused on this solution with one fan, that's what most of you guys will use.

With one fan taken into consideration, when we take this Core i5 processor from default towards 3800 MHz / 1.4v @ CPU we see that the temperatures are not at all an issue -- whatsoever. With the processors stressed we max out at less than 65 Degrees C

Mind you that we measure at a room temperature of 21 degrees C, in hot countries the ambient temperature obviously will also have a (negative) effect on overall cooling performance.

Typically we now take the processor to 4200 MHz with 1.5v on the CPU, however we did feel that the 65 degrees C are closing in on the maximum thermal dissipation so we forfeited with the well over one GHz overclock.

Please bare in mind that the 1.4 volts we used is already high for a 3800 MHz overclock. Typically 1.3v would be fine as well. We use a slightly higher voltage to show you the cooler can cope with the additional heat coming from the CPU.
