Has anyone ever used heat pipes?  I've been looking around and see what look like PPC-sized heat-sinks to attach to heat pipes to pull the heat out to radiators which would easily fit in the case including a blower.  There are even some laptop assemblies which look like they'd fit in the 1200 case including working around components.


I've thought about it many times but I just can't bring myself to hack an Amiga case, even if it is something simple like vents or an opening. I have one from an old laptop that looks like it would fit my A1200, so I suppose I'll keep it forever until I change my mind one day or buy a Kickstarter case or something. I don't have a PPC but I do have overclocked cards which would benefit from such a mod.

I am considering that if I don't need to use the 1230 SCSI any more, I could run the heat pipe along the inside of the case without modifications, put the radiator and blower in a position which would exhaust out the back trap-door opening.

I could still use that configuration and just move the SCSI port to another location.  Yeah, I'm giving this some serious thought now.

it would be cool if someone made a metal A1200 case.
Better sorry than worry.

If I still had access to a laser cutter (my customer closed his shop), we could have banged something out...

I ran a Blizzard 060/PPC with BVision in my A1200's case by peppering the trapdoor with holes for ventilation and adding a small fan underneath the upper back vents. I didn't seem to have any overheating problems, but I may have been lucky in this. I also very carefully soldered some wires to the power socket input pins to connect to the pins on the Blizzard, although if anyone was going down that route I'd very strongly advise to check and double check the voltages before plugging it in...

Cheers,
Nigel.
