Heat difference between non-OC and OC systems?

[Drakodan]

Assuming that all other factors such as case, cooler, load and environment are equal, what sort of heat differences can one expect between a system that isn't overclocked VS one that is?

I'm curious to know how much extra heat I'd be looking at if I were to buy a pre-OC system, both on idle and under load. Let's assume I'm running the Noctua cooler, for argument's sake.

That will vary from CPU to CPU (as in, one i7 8700k may well run at different temps to the next). Also to some degree, temperature is just a number. A gaming PC with a CPU running at, say, 72 degrees rather than 68 degrees under load isn't likely to snuff it meaningfully faster.

A lot of people seem to have quoted temps in the 70s for an OCed i7 with the Noctua cooler under heavy gaming load. Which is more than fine.

The temps won't be all that high, not least because PCS's overclocks are reasonably tame. Enough that you can see a difference in some situations, but not enough that your PC melts

Google-fu is your friend here, if you know the components you're looking at and the approx. overclock values you expect you can get a good feel for the additional heat output by looking at the various reviews for similar components online.

+1 to the above.

Although do note that a lot of reviews will OC CPUs to, say, 5GHz, which is a lot more toasty than 4.8GHz.
