how to fix a noisy fan.

step 1, unplug and let it cool down.
step 2, carefully remove the fan by unscrewing the 2 screws and unplugging the power
step 3, using tweezers or something, carefully remove the silver sticker on the back
step 4, place ONE drop of light machine oil in the center hole.. i used the oil that came with my electric beard trimmer
step 5, let the oil sink in
step 6, put it all back together. you don't need to tighten the screws really tight.

plug it in and enjoy your silent moonlander.

This seems the best suggestion!! Yesterday I removed all the stockfans (I have 11MLDs, some running at 832Mhz, some at 900Mhz, all on 1 hub). But then I felt that the units were getting too warm, it just became a mess. I tried one more external fan (from 3 to 4) but that didn't help much, so then I oiled the fans, put them back on, and now it is much and much better, I would say 6dB down (halve the noiselevel). So I will stick with this solution in the end, for a long time to come. I was not able to put the sticker back on, it didn't want to stick anymore.
