Is there any way to convert a DC 12v fan into a DC 5v fan? I can't find a 5v fan and it's getting highly annoying.
What's airflow about? I mean the numbers, compared to the price, theres a cheap 6$ 5v but 6.6CFM of airflow. Don't know what to expect from a tiny 5v fan.
CFM is cubic feet per minute. How many cubic feet of air will the fan move in a minute. Computer fans, for example, go everywhere. You can get a huge nasty loud fan that will sound like 3 or 4 rock grinders, a space shuttle launch, and nails on a chalkboard (all at the same time) that will move 100cfm. Or a really really quiet one that only moves about 5-15
well like 4cfm is a good airflow? It's going to be in a mouse (to cure sweaty palms). Would it have enough flow to be actualy felt?
well if you perhaps made the shell of the mouse, where your palm rests out of a metal such as aluminium, then had the fan blowing onto the aluminium, it would keep it pretty cool!
This type of project was up in a swedish forum recently, the general conclusion was that cooling your hand down is a really great way to get rheumatism (i hope it's called that in english too, pain in the skeletal joints) This kind of cronical disease is normally an age disease, but it is known for people as young as 20 to get it from for example driving mopeds without a jacket and gloves in the winter.
well no, I was gonna drill holes into the mouse, on the side for air intake, and on the top to blow the air onto the hand
ROFL I seriously doubt that as it's a fan curculating Florida air. Doesn't get much hotter then that lol
thats cause youre only supplying a fraction of the power it wants to run at full speed Why do you need a 5v fan anyways? if 12v creates too much noise, hook up the positive line to a 12v lead, and the ground to a 5v lead, thus creating a 7v fan. Quite, slow, better than 5v at least.
