I'm looking for a better (and more effective) method of cooling my prints on my Powerspec 3D Pro.

I bought a 12v fan, thinking it would be powerful enough to power this. I realized that there are 24v fans too, but I am unsure if those are powerful enough for cooling prints. I am already set for a power supply; I use unneeded AC-DC laptop chargers to power my projects.

I might consider connecting a fan to my board if that is a better solution, so please, tell me what works for you Replicator (and clones) owners! Thanks in advance.
