FAQ:

Q: What kind of power supply do I need for a fan?

A: The native cable is 5ft (1.5m), but can easily use any standard 3pin or 4pin extension or splitter. 100-240vAC switching input power and 12v 1A max output (12w). We recommend that you do not run any power supplies at more than 75% of max rated amp draw for extended periods of time.

Q: What kind of converter do I need for 12V fan?

A: The Dc Regulator or dc-dc Converter would be the best, but most costly methods. You can by ready made small buck converters for less than $10 on eBay that will do just fine. Check the current rating of the fan to determine the size of your converter.

Q: What kind of power supply does coolerguys use?

A: Coolerguys is proud to launch our most cost effective branded 1A power supply. We simplified to have a 2510 (3+1) fan connector to directly power either a 3pin and 4pin PWM fans with no adapter.

Q: Can a 12V fan be gated off by a capacitor?

A: Make a simple square wave oscillator with a 1:1 mark:space ratio. Use it to Gate on and off one or two masters. UT a reservoir capacitor across each fan, and they will see 12V. Get bone idle and use one, or two, monolithic voltage regulators to supply the fans. Plus heatsinks and capacitors.
