40mm fans
 

what fans are everyone using for the quark heatsink. i can't seem to find any larger than 30mm. i can't find a 40mm on any hobby page i know of.

I have two of these:

One is on my Dark Impact cooling the motor down, and the other will cool down the Mamba Max on my 1/8 buggy and Revo. Too bad they're sold out!

your best bet is an electronic parts store a computer parts store... they are really popular there...

the ones that metalman gave you a link to....I called them and they have been discontinued, and will not be carried any more, BUT...i did find them here

or

so they are not in fact 5-6v "novak like" fans for rc but 12v computor fans. correct?

They are 5v fans, so they are made as 5v computer fans. They will work just like the Novak 5v fans.

I just picked up two of these. They move more than twice the air of the 25mm novak fans.

This is what I have been using. Works great. Just put a servo plg on the end of the wires and plug it into the 3rd channel on the reviever. That way you have easy disconect for maintenace. Nice and ligthweight frame on these fans also.

Any of these listed in this thread will work fine.
