Its snowing here so i thought this would be a nice time to start my cooling similar to @sat_be s Build: [Daniels (un)geared inflatable (slowly built) - #72 by sat\_be](https://foil.zone/t/daniels-un-geared-inflatable-slowly-built/8069/72)  
This solution is much more easy because a water tube could disconnect when the radius is getting to small. The Summer gonna show if the aircooling is enogh 😅 .

So i bought the biggest cooler i could find, around 300_100_20 and cut it down to 200_100_20.  
After that I trimmed ~8 - 10 mm flat plane around.

Then I made a hole of the size of the cooling fins in the box.  
The direction of the fins is going to be in the direction of surf. This should lead to a maximum air cooling.

The heatsink got several screws to hold it in place. Its seals with Silicon all around.

I Placed the VESC directly on the Heatsink with some heatpaste and two screws.  
The screws are also seald with silicone.

It looks like its all Waterproof 😁

Made some Isolation with some rubber from a bike tube. And placed all the components and made some nice cabeling. The placement of the components is pretty nice. If water comes in they stay dry a long time. But the batterys gonna melt 😇.

The edges of the heatsink are really sharp. If i fall i directly fall over it. So i Made some PETG protection frame around it. There will come an aditional one for the screw of the VESC.

So next steps gonna be:

1. Test it 😃
2. replace bearings
3. replace the old mastmount with the new hydrodynamic improved version.
