I have a brand new Triton. The first discharge I did was with a 6 cell NiMH pack at 1A. The fan turned on immediately and ran through the discharge. Since then the fan has not turned on in any discharge cycle all done on 6 and 7 cell Nicad and NiMH packs at 1A. The housing gets quite warm. I measured at least 113F at the fans. I called the factory and they told me that "theoretically" the fan was supposed to run any time it is in a discharge mode. Any comments would be appreciated. I am a real "newbie" at this. Thanks
