<p>Hey Nick,</p><p> After seeing you purchased the 5V variant I went ahead and threw a set of 3 on my Kossel. Running them directly from a 12v source caused the first test fan to smell pretty bad and get too hot for my taste so I wired the next one to my Azteeg X5 controllers 12V fan output(should function the same on a Ramps board). If you stay under 70-75% output the 5V fans actually produce more air volume and so far have served me well for at least 40 hours of printing without getting too hot. </p><p> I'm currently running 3 5V fans all wired to a single output on my Azteeg X5 without issue. </p>

I jumped the gun, but I'm sure I'll find a use for the 5v fans ;) Thanks for the link to a 12v.

<p>Nick, be careful buying those. They were originally shipping 12v fans but all of the new ones are 5v and overheat at continuous 12v. I'm able to run them at 50% output from my Azteeg X5 controller but they don't put out nearly the air as a true 12v plus they get twice as hot.</p><p>I just picked up one of these and it was 12v as the picture shows: </p><p><a rel="nofollow" target="_blank" href="http://www.amazon.com/Black-Brushless-Cooling-Blower-5015S/dp/B008P72QYS/ref=pd_sim_pc_8?ie=UTF8&refRID=1FJXZD1EWXKJ9WRT0V7F">http://www.amazon.com/Black-Brushless-Cooling-Blower-5015S/dp/B008P72QYS/ref=pd_sim_pc_8?ie=UTF8&...</a><br></p><p>Forgot to mention I'm now running 3 of these fans in a 120 degree layout with great success. Two would probably suffice but I print at 20-40mm second so the weight doesn't affect my quality and helps with ledges and bridging. </p>

I like this concept, going to try it out.
I'm guessing you picked up these? http://www.amazon.com/Vktech-Brushless-Cooling-0-1-0-3A-50x15mm/dp/B00EL938E6

<p>Works perfect with my 5015S fans. Picked up 5 for $11 shipped second day air from amazon.com (they are listed as 5v but actual fan indicates 12v). </p>
