Popular Post PotatoInside Posted June 9, 2018 Popular Post Share Posted June 9, 2018 (edited) So today i was bored and had some slight OCD about the charger being so hot when in use i Gathered a bunch of garbage together... 12v Power supply from who knows what... Some crappy 92mm Fans I simultaneously have no idea and some clue as to what im doing, no plans, no sketches I have a feeling this really ghetto cooler will actually be quite good, 1 fan is intake (300mA) and 1 fan is exhaust (250mA), slight positive pressure in the box i used some breadboard wires to keep the charger elevated in the box so air can pass over all the sides this is how i normally charge my KS16S but the PSU is ridiculously hot 50°C hot! and the temp was still climbing after 15 mins I threw the charger in the Ghetto Cooler and it dropped to 1°C above ambient after 10 mins (Today is 25°C in Calgary, the charger is only 26°C) Edited June 9, 2018 by PotatoInside 7 2 Quote Link to comment Share on other sites More sharing options...
Popular Post Hunka Hunka Burning Love Posted June 10, 2018 Popular Post Share Posted June 10, 2018 (edited) Nice idea and well executed! But ever watch "Survivor," and see how they blow on the burning embers that are surrounded by tinder all around? Maybe a plastic box might be better. Calgary? Where the heck is that? Sounds like a weird name for a city. Edited June 10, 2018 by Hunka Hunka Burning Love 2 2 Quote Link to comment Share on other sites More sharing options...

I have heard that boredom is the mother of invention; or was that necessity. 1 1 Quote Link to comment Share on other sites More sharing options...
mrelwood Posted June 10, 2018 Share Posted June 10, 2018 50•C is actually on the lower end of the spectrum on the fanless charging bricks. But inventing is always cool! 1 Quote Link to comment Share on other sites More sharing options...

ir_fuel Posted June 10, 2018 Share Posted June 10, 2018 Actually that intake fan is not needed at all, and could even be counter productive. If my memory serves me right, what you need is: - exhaust fan on one side - holes about twice the size of the exhaust side on the other side.

Im pretty sure you know where Calgary is, if you look out your window you should be able to see it! its because Calgary is the center of North America, and North America being the greatest, is the center of the Earth, Earth is the center of our solar system and everyone wishes they could be here.

ir_fuel Posted June 11, 2018 Share Posted June 11, 2018 I'm not saying it needs to be made more efficient, but chances are you would get the same result by simply removing the intake fan and leaving the hole open. Quote Link to comment Share on other sites More sharing options...
