Saturday night i was running my itech 8000 on 4 Jbl Vrx 932s (2 per side) and after 2 hours the fan didn't come on (the fan inside the power supply didn't come on either). I put my hand by the back of the amp and it was pretty warm. I have 2 Xti4002s and a lab gruppen 7000 and the fans were all running on those. I checked in the menu for thermal errors, there weren't any.
Has any experience this before? I wasn't clipping the amp but it was definitely getting pushed (4 ohm load per channel)
I am running the latest firmware.
