im totally clueless with electronics and need ventilation pronto can anyone help by telling me how to hook up computer fans to the mains power supply ?
There are two threads currently on the front page. Both explain ways to do what you want. One covers hooking them up to a DC adapter: http://forum.grasscity.com/grow-roo...w-connect-your-pc-axial-fans-12v-adapter.html And one explains how to convert a computer power supply for direct use: http://forum.grasscity.com/grow-roo...ply-run-your-entire-grow-box-fans-extras.html Good luck with either one you choose. If you choose a method and ask questions in that thread, they will benefit everyone and anyone who takes time to post a how to, I am sure will take the time to answer questions to help you get it done... (including me, which the power supply method is my thread)
