My Quark Heatsink - RC-Monster Forums

Hey dudes... why do you think 12v fans are bad or can move some good air???

I have run both 5v and 12v. Some fans are definitely better than others... some are duds and some work great.

I have always run 12v fans on whatever the pack is. So a 4s lipo would really make a 12v fan boogey I would think.

BTW, when I get a 125b I think I will try to stick it to the alum chassis and see how that does as a heat sink... no added weight, clutter, etc... it's a free built-in sink with lots of airflow under the vehicle. Anyone try that with a Quark? (buggy/truggy)

On 5s or 6s lipo, you will boogy the blades right off of the fan.:005:

Not to mention the fan motor will burn up in no time. On 5V off the BEC you can run whatever battery you want and it doesn't matter.

12V fans are fine if you are running only 12 cells.

Hi, I am running a 12 volts 6x6 fan with 5S lipo without problems since a month or
two.

I hope you mean 60x60mm - 6x6 would make a hovercraft...

I am running 2 12v fans on my quark heatsink - I got 35 mins of solid run time and its still holding - but boy does she sing when i plug her into the 5S....
