Well, I've had the NOSS head for a couple of months now, and I've seen a very big difference with it!!
I can almost touch the head for a bit without getting burned right on the spot... I did that a couple of times with the stock head and it smelled like roasted pig after that
Add to that the impeller, an inline cooler & some water-wetter and you'd be able to go roostin' on the sun and 'shee wouldn't overheat :wink:
