Hi, So I just picked up this DB750 and it sounds great. The fan noise (IMHO) is another story. I can see this being no big deal when playing live with a band - and indeed that seems to be the consensus on here. Unfortunately, I'm usually playing in the living room semi-quietly these days. Just out of curiosity I looked into replacing the fans. I haven't cracked the case open yet but I read in another thread here that this is the culprit: 3110KL-05W-B30-D00 31.8 CFM (0.890m³/min) 0.106 in H2O (26.4 Pa) 2700 RPM 28.0dB I looked around on Mouser and Digi-Key and found some comparable fans; several of them are quieter (down to 17-ish dB) but of course with lower CFM and static pressure. My question is - is it safe to replace these fans with something that's in the 23 CFM, 1850 RPM range? There are some Sanyo Denki fans with those specs rated for 20dB - like this guy. Seems like a pair of these would be substantially quieter, but will I cook the amp using these lower-volume fans? Edit: I should add that I am definitely not going to ever be driving a 2 Ohm stack of speakers at arena volumes. Might be powering a modest 8 or 4 Ohm load at quiet suburban levels, though. Thanks!
