Is there a relationship between the Temperature of hardware and it's Performance?

Obviously when the hardware becomes higher than it's stable temperature it will crash, putting performance at 0, but I'm on about when it is running.

Would a GPU running at 70c be hindered by it's temperature compared to a GPU at 40c?

If not then I can run my fans a little slower to decrease the noise, and have a slight temperature increase.

What GPU do you have?

These days, you can expect normal operating temperatures between 70 - 90c and still being absolutely fine.

Depends on your GPU though :p

4850, which I have heard to be a hot card, yet I get temps of 50c max when OverClocked.

I'm looking to get a 5850 and mostly wondered whether Vapor X was viable or not, but it seems I'd be wasting my money.

I was also considering an after market CPU cooler as my CPU gets toasty when OCed, yet as my maximum temperature there is 70c (which you state as normal) I think I'd omce again be wasting money.

Thanks a lot.

Or to put it more bluntly : will the exact same CPU running at the exact same clocks/settings with all other things being equal perform any different in a 10 C environment as opposed to a 60 C one.

Put perfectly.
 
So are we on agreement that at 70c the Frame Rate would be the same as at 30c?

This applies to both CPU and GPU, sorry that I confused it with just GPU by using that as an example.
 
In conclusion, there will be no noticable short term effects to performance depending on temperature, only long term effects.

My reasoning is the extra gain from overclocking yields more performance than you could gain by spending on dropping the temperatures to try and gain similar performance.

Sorry if I'm getting the wrong end of the stick here, but if my CPU Overclock is at it's limit (because if it goes higher the voltage needed produces temperatures which crash my computer) does this even apply?

Last question of the day (maybe a new one tomorrow :) ) is it worth me getting Vapor-X or is the extra 35 Pounds not worth it? And just how good is the iCooler?
