RV fan upgrade - modification

Well, I grew tired of the noisy range hood fan in our RV and decided to replace it with a PC fan. We shall see how well it holds up to moisture, but actual air output appears to be similar to what our old one was and I lowered the decibels from 85 to 62 (measured with my meter).

If you decide to do this, be sure to get the dual ball bearing type as those are the only style that will last if installed horizontally. I got mine from Amazon for $16.

I looked at the fan you installed and like the idea. A couple of questions come to mind.
  • The specs state you can select the speed. Which did you select?
  • Does it still have hi/lo operation via the microwave speed selector?

I selected the high speed for those low decibel readings on my post and desired airflow. My RV fan switch does not have a high/low setting; I could add a toggle switch and bypass the one built into the fan if I wanted to lower the speed or add a 2 speed switch.

I've used it for the past several days and even cooked the real test: bacon. Plenty of hot air exhausts from the RV from the stove and it seems to be working just fine so far. Still doesn't stop the smoke alarm from going off.

Our current hood is a ventline which is 100 CFM. Upgrading the fan increased it to 171 CFM and less noise. The PC fan is designed to range in speed from 40-171 CFM so it certainly would support being variable with the right controller or perhaps the toggle switch as I mention above for 2 speeds. The lower speed might be wise to run for general air circulation like what many newer homes have. I'm just content for it to be running at high speed and dramatically quieter.

No warranties, expressed or implied. . I kept tie other fan parts in case it fails and I need to swap it back.
