I completed installing an Infinity 40mm USB cooling fan to keep the Prime 2 operating cooler. I perform in many different environments that sometimes can get very hot such as a loft in a barn. This little fan keeps the air flow moving under and through the prime’s side and rear vents.
Hope this can be of help to other DJ’s who play in warm environments or just want your prime to run cooler and last longer. Please note I do not use the usb on the Prime to operate the fan. If you don’t have another available usb they sell an ac adapter to plug into instead.
