Product review (4 stars): I'm Just Sayin', It Should Be 5 Stars
Man, this is tough. Does it work? Yes. Is it easy to install? Yes. Does it cool the tower and cut the foam problem? Yes. So Jeff, why only 4 and not 5 stars? Well, I wrote to the seller ( a really nice guy) and we discussed the one issue I have experienced. Because the keg is kept at 40 degrees we have a cold environment. The fan used is a CPU type fan. Very efficient and usually quiet. However, when put into a cold environment it is operating opposite what it was designed for. The design is to be in a hot enviroment and evacuate hot air. In a kegerator things are reversed. Cold environment moving cold air. The result for me was on start up the motor on the fan makes a loud squeal. This lasts for 2-5 minutes until the rpms warm the shaft and the bushings or bearings warm up. Then the unit goes very quiet and you can't hear it running. Some folks will want to only run the unit when they use the kegerator. They will hear starup noise ( maybe - remember, I'm an  n of 1). We looked at the specs and the MTBF is >20,000 hrs. So I just leave it on 24/7 when a keg is in. The Watt Minder I have says this thing will cost me almost $4.00 over 2 years running every day. If it croaks, you can disassemble it and put in a fan for, oh, maybe nothing if you have an old computer laying around.
