Does heat always rise

[atwon23]

Im goin to OC my AMD Phenom II X6 2.8 GHz Processor. Ive seen other people post that they could reach 3.4 GHz with out raising
the voltage. If that is the case will there still be a big increase in heat? And how much of a difference would going to 3.4 make for gaming.

GPU: NVIDIA GeForce GTX 560 Ti 1GB

Yes it always rises!
As long as you have a decent case and a good aftermarket cooler like a 212+ you won't have temp issues with that oc.

I bet there's a scientist out there that could dispute that. Water doesn't always flow south you know.

I think in this case the question should be translated to "does heat always increase;" the answer is if you increase the power used by the chip, e.g. by overclocking it, I cannot imagine how it wouldn't. If you are able to LOWER the voltage and still maintain a stable overclock, there may be no increase in heat.

Water doesn't always flow South, but barring the application of centripetal force (e.g. in a moving container), it does always flow down hill.

With no outside influences hot air rises above cooler air. But there is airflow in the pc case so the air will flow with the current. It's simple fluid dynamics and convection.

But more important is before the heat gets to the air, your heatsink needs to be good enough to dissipate the heat off the cpu, and this is conduction through the heatpipes and fins; which can be in any direction depending on the shape of the solids.

But to answer your question, no there isn't much more heat without touching the voltage but there is still more. Temps is dependent on ambient temps, case airflow, and heatsink (and of course how high the OC is). How much it affects games is dependent on the game and res.

Thanks. I think there was a fairly recent SBM where they got a nice OC on lowered voltages, which helped keep the temps under control very well.
