    I've got a GK 700RB/210 combo that has a fan vent on top of the amp. Is this vent for air intake or exhaust?

    I have a separate rackcase that I want to put on top of the GK, but this will leave only a few millimeters of space above the vent. How crucial is this vent? There are vents in the front of the amp as well.

    I believe it is an intake, and vents out the front of the amp. I have an 1001, and honestly it seldom ever kicks on. When it does, I am playing really hard for a long period of time, and don't pay much attention. Regardless, it needs to have some access to air around it. I would figure .5" would be good enough, maybe a little less. What I would probably go ahead and stack it, and keep an eye on when the fan kicks on vs when it used to. It will probably heat up more with the restricted airflow, so keep an eye on it.

    It's an exhaust fan. The heatsink is right underneath it in the middle of the amp.

    The fan on my GK700RB never comes on as far as I can tell, but personally I wouldn't put anything on top of it since that's where the heat from the heatsink comes out, fan or no fan.

    FWIW the fan on the GK1001RB that I used to have came on and off periodically, and the fan on the new GK1001rb-II that I just got seems to stay on at a slow speed most of the time (it's very quiet, you can only tell it's running by looking at it).
