I have this idea for a cooling option on my phat box. I was going to mount a self powered usb hub internal to my box. The purpose of this is to run fans. Due to the low draw of usb 5V i was going to use a 12v step up circuit on each port. Reason I think this might be a good idea is because i don't want to add additional heat by running off the boxes usb and I would be afraid of shorting them out. Also in case I f*ck something up i just toasted by usb hub not my box. I know I can solder in the 12V front fan connect but I don't want to pull to much power from it with multiple fans. I also figured i could run some other stuff like leds. I just think the option of having additional power inside that isn't powered by the psu is a good idea. What do you guys think?
I do of course realize I will have another cord coming from my box and will have to manualy turn off and on...unless i solder in a wireless on/off switch
