    I swapped the two 24v 80mm fans (two wires) in my cdi 4/1200 bl with low-speed ones with great success.

    I recommend fans that spin at around 2200 rpm (about 27 dB) instead of the 1500 rpm (17 dB) that I bought since my channels are now running at around 68 degrees.

    It's dead easy to change the fans, so no worries.

    That is great that that worked for you! I have since swapped out my DCi amps for fanless, 400w Purifi modules (x6) and a BSS BLU-800. I swapped out the fans in the BSS unit as done by many others on this forum and am thrilled with the silence and performance.I couldnít have done it on my own, so Iíd like to send a shout out of thanks to one of our longtime members, Grumpy, for the help and encouragement to make this change.

    @tommytoa, Do you mind sharing product link to low noise 24v fans? I have problem finding them.
