In line 3" blowers.

There seems to be a big difference in price of computer cooling blowers {£6-15} and marine engine room blowers {£27-50} .
The only physical difference seems to be the casing.
Any views?

Ignition protection?

The difference is in performance! The engine room blower will typically move around 10 times as much air.

Was thinking the same question over the weekend - checking on various sites, seems the in-line blowers have a current draw of around 3 amps, with the radial type drawing a bit over 4 amps.

Interesting if a x10 air movement is achieved with only 30% more current draw?

You'll find that the OP was comparing computer cooling fans with proper engine room blowers. That's where the 10x performance difference is.

Lesson is - read the OP post properly!
