Ventilation - Exhaust Question On L3+?

I had read somewhere (can’t recall right off hand) that venting the exhaust of a single L3+ using 4" vent pipe would actually increase the temperatures on the board and chips.

What would I be intending to use? This Flange and a small run (less than 3’) of 4" flexible dryer type venting to a flush mounted (through the wall on my small shop) louvered vent.

Is this a mistake waiting to happen?
