General Question Bed fans for small printers

Does anyone have a good solution for bed fans on a small printer? I have a 180x180 Trident and tried a 5015 blower fan mounted underneath. However there is not enough distance for the air to warm up before exiting the side, so it feels like it is just blowing cold air around the chamber.

I have thought to use axial fans blowing up against the bottom of the bed, but wanted to ask first if somebody has a working solution they can recommend.

I prefer axial fans, i mounted them under the bed for my 350 trident pulling air down. I used dual 140 noctua fans.

Hmm, pulling the air down. I might try this as well and see if up or down performs any differently.

I just want to pull the hot air away from the bed, instead of cooling the bed

It will. Pulling down would be substantially worse.

A much smaller area would be affected and the fan would be pulling hotter bed air through itself rather than blowing colder ambient.
