No emergency here... I've just never noticed it running before... the cooling fan comes on and runs for about 30-45 seconds, as you would expect it to if the amp were hitting a thermal setpoint. But it seems to be cycling whether the amp is 'working' or not. By that I mean- the amp is powered-up, but not amplifying anything... just in the ON mode. Idling so-to-speak. My issue isn't about the fan noise... (which seems to be what every other thread on the entire planet is about) it's so quiet in fact, that I can't actually hear it, but by chance I happened to feel the breeze and upon investigation, found it was turning. Guess I'm concerned because it doesn't seem to be hot. There are no issues with operation either. I'm only running it at half it's capacity (channels 1 & 2 volume set at noon each) and not underloading it at 4 ohms each side. (should handle 2 ohm just fine) Just wondering if this is actually normal behavior and I've just never noticed before, or is it a sign the amp's cooling system is about to fritz. Anybody else had a similar experience? Thanks in advance... If you come up with something, I'll have Jeannie grant you a wish - just be VERY careful what you wish for.
