LED fan power consumption?

[Monkey_feces]

I just got an Antec 900 from comp usa and the one thing i can say about it is FSCK WATER COOLING! Anyway, i plan on leaving my computer on 24-7 stealing from directors and game companies. Would the LED lights from the 2 fans increase power consumption by much?

Not really. Alot of LED fans use the power generated by the spinning of the fan to light them up.

Well, if that's the case, then those LED's would require more input to the fan hub... Energy isn't free... So the kinetic energy required to spin the fan would increase, if it was being leeched to light the LEDs

As a "safe" count... You can assume that there are 4 LEDs on the fan, each operating at 3v. Since 12 / 4 = 3 there's probably no resistors in the LED wiring...

THerefore, since they're (probably) in series, you can expect a current draw of about 40ma @ 12v giving you a power consumption of .48w. The fan it's self would have power draw too, because of the motor (probably about 1-2w for the fan)

If they're (for some reason, or it's just a better designed fan) in parallel (i've only seen this once I believe) then the draw would be significantly higher, but still under 2w for the LEDs and 3w for the fan (as a maximum).

Don't worry about it.
