Yeah, just connect them up so they are always on. I'm surprised you bothered with fans as a decent lump of finned heatsink does the job very well. Here's a picture of mine, with the software modified to give over 600A and I've yet to see the heat spreader (mine's Cu) temperature go over 45 deg C even on a warm day (air temp 28 deg C)
The 4 bolts you can see are the ones through the heat spreader and there are 4 more, short ones, that simply clamp the heat sink to the case. Lots of thermal grease between spreader/case and case/heatsink.
You might note that my case is upside down to the original design as I didn't want the mounting flange on the same side as the heatsink - for obvious reasons.

Sometimes I sits and thinks and sometimes I just sits.
