here are some comparison pictures . first two are from the stock cooler and the next two are from my upgrade cooler. the last two pictures the stock is on the left and the upgrade is on the right.
here is a pla alternative to the stock metal cooler on the wanhao i3.
its lined up with the extruder . its lighter and works way better than stock.
( will post comparison pics tomorrow.) (pics are of my test cooler.1st version working great..)
one is 30mm for people that want to run the stock fan.
others are for a upgraded 40mm fan.
