RJT,
Thanks for the info. Silenx has a 12-24dBA heatsink that is very
similar in design and price to the Zalman 7700Cu but there appears to be
some issues with RAM clearance. Did you have any difficulties?
Nope, fits nicely over my Corsair memory with heatsinks (Corsair TWINX
2048-3200C2), there's even a tiny bit of room left. I can even - with a
bit of jugling - get the mem modules out of the bay nearest the CPU and
move them about with the Zalman 7700 installed. It's not so much cooler
under load as it was with the standard fan - still about 60C at max load
with an ambient temp of about 22C - but it's so much more quiet.
As for the manual controls with the zalman: you get a controller you can
stick to the outside of the case, so you can control the fan without
opening the case. That said, I don't use it, as the automatic built-in
Q-fan controller on the board does a better job. It pumps up the rpm
when the temps go up, so I don't need to turn a nob all the time.
