i just received a 92mm tornado fan and i installed it in my computer. i hooked it up to a 4 pin molex, but it was way too loud. the other solution i came up with was to hook it up to the motherboard 3-pin fan thingy so i could control it with smart guardian. well basically i spliced that fan together with another regular 80mm fan into the 3pin fan thingy (individual wires for both). i booted up my computer and everything was fine and it worked, i installed the cat 7.5 drivers, rebooted and upon loading windows, my monitor would turn off (no signal). i rebooted in safe mode, uninstalled 7.5 and rebooted, and re-installed cat 7.4. it was during this time that my computer shut down out of no where. at first i thought i killed the power supply, because i might've been pushing it with the new fan. well nothing smelled burnt or anything so i basically disconnected everything except the cpu/hd/ram and tried to see if the computer would at least beep or something, but all i get is a red led lit up (bottom one) when the power supply is plugged in, and when i hit the power button, another led lights up on the motherboard (near the cpu) and that's it. the power supply fans don't turn on, system doesn't post, nothing. this leaves me to thinking that i did one of two things. fried the motherboard (maybe it was draining to much power from the fans) or i dunno if this is possible, but killed one of the rails on the power supply (hence why i get led's but no boot). fortunately my buddy has the same power supply and motherboard as myself. problem is, that one of the capactiors on his motherboard got ripped off during shipping. right now, my next steps for troubleshooting are to try his power supply, and if that doesn't work, to look over my motherboard more carefully, and then de-solder one of the capacitors from my board to replace his, and then try his motherboard. what do you guys think, any suggestions? i'm overseas right now, so i want to make sure i narrow down the problem as much as possible before i start ordering stuff. ps - power supply calculator says i'm using about 331w.
