Aussie Desert Cooler has a range of thermo fans to suit every application. Most V8's require approximately 2000 cfm (cubic feet per minute). 

If you keep this in mind when you are buying thermo fans you will not waste your money. 

In our range, the 16" thermo pumps out 2800 cfm, our 14" pumps 2000 cfm, and our 12" pumps 1000 cfm. 

So, if you cannot fit a 16" thermo, we recommend and fit two of our 1000cfm 12" fans - this gives you 2000 cfm in total!
