heater..... the fans are making a lot of noise.. I want to oil the
fans, what type of lubricant should I use? silicon spray or wd40?

Neither. Use an oil designed for motors, such as regular 30 weight
non-detergent motor oil. Used to be 3 in 1 was good for that but I don't
know if it still is.

The fans may be noisy for other reasons too. Poor design, something hitting
the blades, etc.
