Since Thermal Radar showed the Assistant fan 1 slot as a top case fan, I tried plugging my Antec 1200 Top Case fan into it (as im waiting for fan splitters) It worked fine up to a limit of 750 RPM by Thermal Radar, the fan is rated 800 RPM. The manual states that these are for "assistant fans" only and I had no idea whether I really made a mistake as I didn't see any further documentation for the fan that would plug into Assistant Fan 1 as it isn't provided with the motherboard or mentioned beyond the power plug. I haven't been able to locate a discussion about this or any further information.
I say this because I did experience a few cases of the motherboard shutting off the computer due to power surges and I unplugged the top fan from the assistant fan slot and haven't had that happen since. I don't know for certain if that was what was causing the surges as it was working fine for a few days prior but like I stated it has been shut off free since. I thought I would put this information out there if anyone runs into a similar problem. I plan on contacting ASUS directly in the future about the Assistant Fan 1 and I will update this thread then.
