well ive got a pc case grow box ive got 1 cfl 100w for veg if i use to 100w bulbs dose that make it 200w? and i need to know how can i get a pc fan working without a pc power supply ?
If your fan is 12V, which most are, then it will be enough to power it... just not at full speed. I tried using a 5v cell charger and barely got half speed on a 12v fan, however, I'm now powering two 12v fans with a 15v transformer and they are running at full blast.this is the phone charger i found input 230v output 7.5v would this be fine?
