That's pretty impressive although it still makes quite a difference as to what type of HSF is being used along with the range of core temps that frequency produces.

It is possible to get an E8500 close to 4ghz with an extreme air cooling solution (like a Thermalright True copper ultra-120 with a Delta 120mm fan pushing 120CFM).

Although frankly, once you start pushing those types of CPU freqs, you're just being stubborn at that point by not switching to a decent water cooling solution.

Air cooling can get reasonably close to water cooling and you get the added advantage of the fan cooling the voltage regulation circuitry as well. You still have to deal with that heat and positioning the radiator can be a PITA. I looked into watercooling not too long ago.

Besides! Real men use phase change cooling!

 

Lol!

The best air cooling solutions can match and in many instances even beat a poorly designed liquid cooling system.

Unfortunately, most of the best liquid systems are assembled from hand picked components ($$$). Cost-wise, the returns are only there if you had the misfortune of buying an expensive ($600-1000+) CPU that was from a mediocre lot that required higher voltages to run the same clock speeds as a better sample and you had the ambition of pushing the 5ghz envelope.

But you can always supplement a liquid cooling system with additional fans and heatsinks, particularly on the NB and SB. Even with a liquid cooling system, you're still going to be putting it into a large enclosure with multiple intake and exhaust fans.

It all boils down to what type of OC performance you're pushing for to determine the best cooling solution, whether it be air or liquid.

I feel air is fine for all but the most extreme instances, which is why I'm not quite sure what's the point of some of the less efficient cooling kits I've seen on the market (they're inexpensive mainly I suppose).

But water cooling is definitely in my future, even if it's just for OC experimentation.
