Review on NTRA Aquarium Cooling Fan Adjustable Fish Tank Supplies 2 3 4 Heads Quiet Cold Wind Durable Mini Temperature Control Clip-On Chiller Energy Saving Fresh Marine (FS 602) by Brittany Moore

This is a nice compact little fan that produces quite a bit of air. It's quiet, as performance isn't impressive, but it's a nice "breeze" that should keep things that require airflow cool. My only issue is that there was some debris in my particular fan and you could hear the rumble inside the case. Six small screws and the whole fan falls apart and after a few shakes it's ready to use. It works, so it's not known where the debris came from. For the money it will work but I don't expect it to last long although I could be wrong and will update my review when I use it.
