In the process of upgrading a system from an E6600 to a Q6600-G0 I noticed that the stock HSFs for both are quite different. If you look at the pic you'll notice that the Q6600 is shorter but is equipped with a more powerful fan.

Now I've been running the E6600 at 3 Ghz without issues for months with the stock HSF and it's been a very quiet machine. Since the Q6600 fan is more powerful I assume it's also going to be more noisy. I have no immediate plans to oc the Q6600 (assuming it can handle the workload I throw at it) could I safely swap the HSFs? TIA for any opinions and suggestions.

I would try both out, starting with the e6600's HSF, test with prime for a bit, and just pick the best mix of cooling (at load) and noise for you.

Additionally (wasn't sure if this is what you meant by your post or not), you could just use the e6600's stock heatsink and swap out the fan with the one from the q6600 HSF.
