So that made me think the threshold for the car overheating and it running And it Overheating can’t be but a few degrees. I had the same experience. I did it 6-7 times in one week trying to debug it and then threw the dreaded code 66. I have no proof but it sure seems like I overheated or pushed it too hard causing it to blow some fets. Just letting people know to be cautious if you are running HV and fiddling with things. ---

@diymatt - we can fix the 66 code if you want - at least we have fixed one. ---

Hey Matt thanks for the Heads up on the -66. Maybe one to many -41’s result in a dreaded -66. perhaps your on to something?? A Ounce of prevention is worth a pound of pain. Hey I can’t find it on you tube any more but there was a guy who made a Heat sink for his D&D motor. He used U channel Aluminum and placed the U channel strips all around the motor and then used a large hose clamp to hold them to the motor I’ll try and make a diagram ---

I am now thinking about getting some 1/4" copper tubing and wrapping the motor in a tight spiral (think motor windings), then running that through a small radiator with a pump. I have looked up the parts and it’s under a 100.00 for everything. Might be a good winter project. ---

Great idea. I can see you milling those slots on your drill press. ---

David: Exactly you could drill threw the Aluminum with a drill doing both sides at once and either using a file or the drill press mill to smooth out the hose clamp slot. ---

Mike: I would think for $20 in Aluminum U channel and A few large hose clamps you would be good to go. No water circulating around your motor and nothing to Brake go wrong. Remember “K.I.S.S” (keep it simple stupid) I could see this being done much easier with the motor out of the car. ---

Grant - you caught me… I can get down the rabbit hole quick with these types of things. K.I.S.S is always the better route, I wish I would take that path more often!!! Yes, out of the car would be the way to go, like I said good winter project. It is already starting to cool off here so as the air temp drops the heat issues tend to drop as well. So I plan to be ready for spring with some type of setup. ---

Take the housing off the motor and rosette weld the channel, strip by strip, all the way around. All you have to do is drill 2-3 holes per channel this way. Not mill out 50 slots. I’m not sure how well the channel stuff would work though. You won’t be making full contact since they are flat and the motor is curved. That corrugated stuff Inwo posted looks interesting since it’s bendy. If anything it’s a fun new way to cut yourself when working on your GEM. I wonder if any of it’s really necessary though. These things are rated for super high heat and technically you are touching the heatsink when you touch the case. It’s going to be hotter than your hand will be happy with. ---

Good points. What if you took a piece of aluminum sheet and bent it in a semi circle to match the motor. That way it could or would have good contact on the motor. Then you could pop rivet or weld the aluminum strips to the bent piece of aluminum. Then use large hose clamps to hold it tight against the motor. ---

Looking back David’s Idea looks the quickest and most efficient ---

Would not have full contact either, but it could still have full air flow with a fan. ---

Back to MikeKC’s idea, tubing, radiators, fans, pumps batteries… Yeah… LOL Wrap that tubing tight around the motor… 🙂 ---

With a HarborFreight hydraulic press I bet the standard aluminum heatsinks we are already buying could be curved. Making a die to get the curve right is the biggest hurdle I can imagine. ---

You could use plywood to make a Die. A 1/2 sheet of 3/4 plywood and you would have all the wood you need. You could cut out a 1/2 moon shaped square pieces and glue and screw and layer them together to make a Die in a few hrs no problem. Wow see how easy it is to but and create stuff with your fingers in a keyboard. 🙂 simply type in what’s. Needs to be done and Shazam it’s done. LOL LOL But on a serious note I’m sure if someone here wanted to make a die and bend up some custom made motor heatsinks I’m sure you would sell what ever you made up. ---

I think I’d just rather buy a pmac with the fins already on it. [Previous page](https://community.electricforum.com/t/help-wiring-new-heat-sink-fans/16819.md?page=1) [Next page](https://community.electricforum.com/t/help-wiring-new-heat-sink-fans/16819.md?page=3)
