I’ve had two of these 8” 12v Noctua computer fans running for six years 24/7 in the engine room. Even without a diesel leak it makes the rest of the boat smell much fresher. It’s rated at 5000 cubic ft per hour so it ‘s moving plenty of air. It draws 0.96 watts (that’s not a misprint) and is almost silent (18db regular speed and 10db on low speed). I made a little mounting bracket out of starboard to mate it to a standard exhaust hose. They have smaller ones that would fit a 4” hose.
It’s also cools the engine room down much faster at the end of the day making the cabin noticeably cooler.
