whats a little cheap fan controller i can use to control my vantec tornado?
i dont wanna spend over $10

would something like this work here them r Its the only prebuilt I saw under that price. You might look at making one all it would take is a potentimeter.
Yould have to find a guide to find the correct ohm rating. (Or ill post the rating on my thermal take controlers one that came with my fan when I get off work)

EDIT Heres a plan for one Here

i dont think it will work with a tornado will it?

Maybe not I wasnt sure about its rating. there is a plan for one though^

$20 is the cheapest one ive seen
