Best method for cooling stepper drivers

Hi,

I've recently made the transition to silent stepstick drivers and also the BLtouch for autobed leveling. The silent stepsticks tend to be hotter, especially on the Z axis, as it is constantly moving now due to bed leveling. I have encountred some erratic movements like shifting layers or missed steps in X , E and Z axis and I can't touch some of the steppers. I have tried lowering stepper voltage but they don't generate enough torque if I do so. I am trying to find the best method to cool stepper drivers. Right now they have their heatsinks and also there is a 40 mm fan but the flow of air is very weak and it can't cool all of the steppers at the same time. Do you have a recommendation for a cooling solution? Gadet3d seems to sell a fan mounting kit with a fan splitter for adding dual fans but their website isn't working right now.

Thanks

Water or liquid cooling would be the best method. I can't tell you if it's been invented for silent stepstick drivers

For the controller and stepper drivers you can use a 60-80mm/12V fan directly fed by the power supply. No need to feed it from a controller port.

I use 40x40x20mm fans. Plenty of cooling.

You can often run 12v fans on 5v to reduce noise and volume of air, I use only one 12v fan running on 5v to cool all 5 stepper drivers which are housed in an enclosure.
