I just stripped one 5 chip down, removing all fans and heatsinks.  I then proceeded to start mining scrypt with it at 850.  I let it run for about 15 minutes, and using the touch test to see how hot the 5 chips get. 

They don't.  Basically warm to the touch.  I don't think these need cooling for scrypt only.  I'm definitely taking the fans off all of mine, and if it ever gets to the point where they take up too much space I'll take off the giant gold sink and put the little per chip heatsinks meant for asicminers/vram. 

I understand why gridseed has the cooling on them for the SHA side of it, I just wish there was a cheaper option for scrypt only with no fan and small sinks.

Maybe one of the resellers can convince gridseed to just sell the boards, I'd buy some that way.
