Modding Nikon supercoolscan external PSU

I've got a nikon supercoolscan 8000 and 9000.

The PSU inside the 8000 gets hotter than the one inside the 9000. They look different, but are interchangeable. Perhaps more temperature limiting measures were taken with the 9000.

Regardless, after scanning for a while the temperature inside the unit rises and this causes the film to increasingly bend. This is especially annoying with the 35mm holder, that can't hold a piece of 35mm film flat to save its life. Same for the MF holder.

So I've been thinking about a non-destructive mod to remedy this problem... quite simply by taking the entire PSU out.

The PSU will be put into its own external box. The PSU connects to the scanner mobo via a simple 8-pin micro jst connector.

This mod should be non-destructive and thus reversible if you ever want to sell the scanner again, because you can just connect your own female micro JST connector to the main board and solder from there.

From here on it should be simple. To the JST connector I solder a 8-pin DIN socket. Then a 0.5 or 1m 8-pin din cable can be used to connect to a socket on the new PSU box. The socket is then soldered to an other 8pin micro jst connector and finally plugged into the PSU.

The box can be made from simple plexiglass I suppose, with ventilaton holes and a hole to press the on/off button.

Have nothing else to do anyways since quarantine.

Your opinions? Is this madness?

Any other unit or carrier mods for the supercoolscans that you have tried?

Is there a fan? If so, has it got dusty or slow? Is there a thick coating of dust on the heatsinks that the converter transistors are bolted to?

If there's no cooling fan; is it possible to fit one? Giving due regard to any vibration it might cause.

To the JST connector I solder a 8-pin DIN socket.

Nooooo!

DIN sockets and plugs are among the crappiest connectors ever invented - 2nd only to a SCART connector.

Splash out a bit more and use a Cannon connector, or anything other than a DIN plug.
