Cool64 - 'Breadbin' Commodore 64 cooler

The chips on the old-timer C64s and 128s run hot, Hot is a recipe for IC failure. With the original MOS chips getting more and more rare/expensive especially the SID, PLA, 6510 CPU, Roms..).I thought id look at how to keep things cool. #1 seems to be heatsinking the chips. But to go extra-cool lets also get some airflow going in that enclosure!

This design uses a fan that draws air through the enclosure and out of the the top vents.

The fan is a 50mm ultra-quiet one from overclockers. I powered it directly from the 12v LDO. A bit of soldering required but the pads are quite big and the chip is tolerant to some heat. Seemed like a safe bet. I added a bit of hot glue to the leads as not to put too much load on the joins when fitting etc.

I attached the cooler t the casing using carpet tape as shown in the pics and a little dab of hot clue at the edges.

The cable uses a connector from an RC battery connector (cant remember exactly which none .Most will work fine. Connector i
