Description

My previous shot at this[1] didn't manage to blow too much air onto the nozzle. Some people were even beginning to try dangerous things to get it to blow harder, like blocking the air path through the radiator fins.

A better solution is, of course, a beefier fan! The standard Mk7 fan is rather wimpy, but you can get 4mm fans which will blow much harder (see the second picture for a comparison). Since there's more flow all around, we can even divert a larger portion of it towards the nozzle, so I changed the duct to do just that.

With this setup, I get quite a strong air flow around the nozzle.
