I got a nice quite 80MM PC fan for my LG. I put in in and used a 12vdc pak to run it. Ive never seen it befor but the fan ran so hard I couldent get the temp below a 101*102* Even with the thermostat turned all the way down. Tried all night into this morning. Finally I rewired it to a 9vdc pak to slow down the fan and now its fine. Now the thermostat will reach 99*-100* at around one third up on the thermostat. Weird huh?
