I have been through 3 or 4 different ones now, and this is the best one I have used so far:
You can get the 50mm blower for a couple bucks on Amazon or eBay.
Printing can be tricky if you don’t have excellent bed adhesion. My first print fell over about 75% of the way through, but adding supports to the areas overhanging the build plate did the trick. In my experience, the green 3M automotive masking tape provides the best adhesion, and the purple glue stick is almost as good. I generally use the glue stick now except for really challenging prints.
Also, definitely do the PID tuning and set your heater algorithm to PID. It works flawlessly with this cooler once it’s tuned.
