Big fan on hotbed might cool down the hotbed too much. Be careful with big fans.
I still prefer small fan on carriage, you don't need many air to cool a bit.
By the way, I had seen your posts and really liked them.
A greeting.
Thanks for your suggestion, fact is that the plastic cooling needs little if any, use the fan to cool over the top of estrusor and especially the engine, however was the only size available to him.
