leo how many sticks do you have ? if you have around 3 - 4 i suggest a nice 120mm fan
if only 1 stick i suggest finding a good small 20mm - 40mm fan ill look around my house and see if i can find one as i go to good will outlet where i find little fans alot in small electonics all the time and they run on 5v - 12 v
I actually do have 120mms in my house and it runs just fine but it's way too loud and I'd rather have a more useful usb fan that I can use elsewhere besides mining. I have just one Gekko stick.
