after several months of rattling and sleepless nights becasue i was to lazy to find the noise i thought it was the fan on top of the CPU but realized it was the fan in the power box. is there a way to fix this i saw a warning that its dangerous to open the box becasue you can still be shocked with the power off. would it still be dangerous if i unplug it all the way?

Please help this rattling is p!ssing me off!!

Several months? Lucky you, take it out and have a look, its only a few screws to remove the p/s, needed to re-route all the attached wires anyways, right? On mine the 80mm fan is easily removed, not so sure of voltage being retained as some components can, im sure someone can assist...(then ill know also) http://sysopt.earthweb.com/forum/smile.gif

There is still power left in the power supply, even once it is off and unplugged - parts called capacitors store energy; some can hold quite a charge. But I have replaced dying fans in 2 power supplies already. A few simple rules - use one hand at a time - if you do touch anything, the power will more likely go through just your hand, rather than risking going through your heart, which could be a fairly big problem. Also, don't touch anything metal other than the casing of the power supply.

And 80mm fan? Lucky you - mine had a 92mm fan - pretty tough to find, let alone getting a ball bearing one. I did manage though - the computer's several degrees cooler now too.

Take the main power cord off (duh) and then take the plug that connects to the motherboard off. Wait a while (there are some capacitors on the circuit board that *may* hold some charge for a while..but not long). Then, just swap out the fan. You have have to do some wire cutting or splicing or something to get the job done--but its not too bad. If you want to skip that and got for an external solution, www.pcpowercooling.com (http://www.pcpowercooling.com) has a fan that connects to the outside of the power supply that is supposed to work quite well.

na you will be safe. i dont think youd get a big enough buz from the capacitors in your power supply, there only baby ones.

Luckily, if you do get a shock it will be DC (assuming that you have unplugged the power cord). DC is much less dangerous than AC as alternating current is more likely to cause heart fibrilation.

DC current is a worse shock becuase it doesn't push you away. It holds onto you. AC shock will more likely push your body away from the current http://sysopt.earthweb.com/forum/smile.gif Learned that from working on cars (DC current)
