Can I use a high speed 12,000 rpm 60mm x 60mm x 36mm computer fan blower in replacement for bilge marine blower

Is it a non sparking fan? You could always make some sort of housing to use it.
You could also use it as a pusher blower so you don’t have to worry if it sparks or not. I would look into how many CFM it can move before bothering with it.

It’s a non sparking fan.
I will be grateful with your support and the calculation for the CFM
How do I upload or attach the picture of the computer blower fan here

I’m not really sure on how to calculate it, but maybe you could find specs of a similar computer fan and see if they have it listed? Most cooling fans list the CFM or the metric equivalent.
Like for the 3" Seaflo brand bilge blower I know it can move 130~ CFM and the 4" moves about twice as much.
Also to upload a picture you can drag and drop the image on your computer to the text box when you start to type out a post, or on the phone there’s a little box to the bottom right shaped like a rectangle with an arrow pointing up.

I would guess that a 2"+ fan that spins at 12,000 rpm is going to be more than enough for most any gasifier. 12,000 rpm is not an ordinary pc power supply fan 
. I have some ~1.5" fans from server power supplies. My son uses them for propane forge blowers. They scream. Good pressure (or vacuum) too.
If you really want a cfm estimate, you might take a big plastic trash bag and lash it around the fan outlet. Turn it on and watch the clock. Google says 1 gallon/second = 8.02083333 cfm. I wouldn’t worry about most of those decimal places .
edit: An easier way is to look up fan, 60x60x32 mm, 12,000 rpm. Mouser Electronics has several, all just about 41 cfm Another question to ask is: how many cfm do you actually get with a particular blower or fan sucking on a gasifier?

Thank you so much for the info.
Do you know the speed of the bilge blower.
I can use a 3 inches pvc pipe as a casing for the computer fan and secure the blower at the middle, just like the bilge blower.
