The cooler a chip, the better it peforms?

From what I gather, that's the case. What would be an optimal temp for a cpu?

So a chip at 40 c performs no better than a chip at 100 c?

Of course not.
The colder you can get it, the better your ability to OC it becomes as long as the chip itself can handle it.
Extreme methods of cooling are used for a reason and that of course being for extreme overclocks.
If cooling didn't matter there would be no need to worry about using DICE, LN2 or other extreme methods in the first place.

As for simply getting it to run cooler, that's always a good idea no matter what you'll be doing with the chip or system as a whole.

For AMD? As close to absolute zero you can get to. The cooler they are, the less voltage they require, thus decreasing power draw and allowing much higher clocks.

All newer Intel CPUs have a cold bug, so they can only take like -50C.

a cpu under -25c would perform better than a cpu at 35c. if youre trying to overclock high, 35c would be too hot, as the higher you go on the frequency the more the transitors are unstable so if its too hot (35c would be too hot for example, 4.7ghz on a Q9550) the transistors wont perform properly. thats putting it simply.

now if your just going for normal OC's and want to perhaps have a higher 24/7 and are on air, then water would help. lets say i wanted 5ghz on my 2600k but 80c was too hot for it to be stable. and i bought an H80 to replace my megahalems which would lower the temp probably 10-15c..that would potentially be cool enough for 5ghz.

I love when people bring up this statistic. As if anyone using less then Liquid nitrogen to cool their CPUs would ever go below freezing.

The issue here is that conjecture is all too often substituted as data; I'll seek to deliver the latter.

You're running an i7-870, so for maximum life, and optimal performance, you just need to keep it ≤1.400v, and between 5 - 72.7°C (Tcase).

Outside the confines of extreme testing (which couldn't care less whether or not the CPU makes it to tomorrow), that would thoroughly debunk the notion of "the cooler a chip, the better it performs".

I think technically the cooler one would perform better... Home made die shrink lol
