Printing this today. Really do need a 120 fan on the SKR 1.3 with the TMC 2130's , they love to over heat on the y axis.

Glad you like the design. I use the TMC2208 and the 120mm fan is a little overkill for these drivers. But that was the only thing I had lying around. Optimal would be a 100mm fan to make the box a bit smaller. Unfortunately, the 100mm fans are not cheap and you have little variety. I couldn't test the TMC2130 yet. Do the TMC2130 run so much hotter?

They run pretty hot, mostly my y-axis has issues when the acceleration is higher. But the silent mode is so good that they were hard to pass up. Having the serialize the Z-axis motors worried me a bit, but they're doing better than the y-axis in terms of heat.
