Fan speed too fasssssttttt Help

[Captainlee]

Hi I have a 12 volt fan was on a car radiator I want to use it to suck the heat out of my ham shack, but it turns too fast what can I put in the 12 v circuit to adjust the speed? Thanks for responding and looking.. Cap

If a variable potentiometer will work what is the Resistance value for the pot?? and which leads do I use on the pot??

How many amps does the fan draw?? What ever it is ensure that the pot can take it or you'll have some other problems.

NAPA sells what you need.

For $20 you can get a window unit from Wallmart.
An auto fan is meant to run high speed and move enough air to be useful for that application.
Good luck.
