I am surprised the VRMs have so few bubbles. I would have expected them to be much hotter.
I was surprised as well. Not many bubbles at all coming off the VRMs.
I am uploading a video to youtube and I will link it as soon as it is done.
The VRMs shouldn't generate that much heat tbh so when you have a efficient way of cooling them they should run quite cool, a few watts can easily create a 100C hotspot if there's no efficient way for it to dissipate.
