me too. i have a quite average cheap case with 3 5.25" and 5 3.5" bays, 
and put 8 drives here.

i needed 3.5=>5.25" mount kits for upper drives, and added small fan for 
these upper drives ONLY because these adapters are made from plastic not 
metal.

no noise, no overheating (i've checked with smartctl)

simplest method is to connect it to +12V and +5V instead of +12V and 0. at 
7V they are silent but still effective.
