DIY fans seem to be doing something that causes poor performance when there are many of them in the map.
Steps to Reproduce
Place a bunch of DIY fans (preferably in a high item condo/map)
What I expected to happen
For fans to not affect performance as much as they do.
What happened
Extreme fps drops when many are in the map at once
Notes / Media
On my lower end pc, my 11k item map was dropping by up to 2-5 frames per fan.
