Hi, I'm just a new user of forum. I have 3 WRT54GL : firewall (shorewall ) with openwrt access point Hyperwrt testing I wish to overclock one of mine, to speed it up to 250Mhz, just to test it, and eventually to put into my firewall customization. I will put some heatsink on chipset,ram and CPU and after I've two choice: 1) take power from PCB (soldering the two fan wire directly behind the power connector, like other users do ) and installing ONLY one FAN 60x60x10mm to pull air OUT I'm not interested about pot, beacuse I'll put the router in a room dedicated to my servers 2) using an external power adaptor and use TWO fan , pushing air INTO wrt and another pushing air OUT I wish to take some advices form users that have done that in a safe way. What is better? And Where to put eventually the two fans? Thanks a lot and sorry for my bad english ( Italian user ) Tommy One fan is enough or not?
