What can I do short of replacing the PSU? I don't feel like cracking open the PSU to replace the fan...the PSU itself is roughly 4-5 years old and it came with my Dell when I bought it. 330w for a Dimension 8100....

Is it kosher to try and get a few drops of anything on the fan to stop the squealing?

I was thinking wd40 but know it's flammable....

Any thoughts are welcomed...

You don't want to crack the P/S or replace it? I'm afraid nothing else is going to get the job done. :confused:

LOL, Yeah Jet powered PC. You either replace the fan or the PSU. Johnwill covered it.

Just as an aside...don't use WD-40 as a lubricant for moving parts. Especially not where they get warm or hot. When the solvents evaporate from WD-40 it gets "Gummy" over time. Adding another drop or two fixes the problem, but not for long. I found this out with a fish tank filter motor. It became 'addicted' to WD-40.

Good ole WD stands for "Water Displacement". It was designed to fight off oxidation on rocket skins in the space program. Liquidized gases as fuels (cold) caused condensation on the rockets in the humid Florida air. Mixed with everything else around it caused a problem with the skins.

It works great to loosen rusty parts, AND to dry out wet automotive wiring.

The "40" is supposedly because it was the 40th formulation that was successfully used.

winbob is 100% correct, WD40 is not a lubricant, and should never be used as one.

Okay, let me restate my intensions then...I don't know why I said I didn't want to crack open the PSU...I have no problems with this...it's not hard to get a part...

Is there any type of lubrication I can use if I take out the fan, shy of replacing the fan as I don't want to be soldering wires in a PSU...

If none of this seems an option, can anyone recommend good 400w PSUs?

Thank you...

I use tri-flow as a spray lubricant. You can get it at most auto supply stores or some hardware stores. It is not cheap, it runs around $10-$11 per can.

BTW when you open your ps, do this first. Disconnect the cord from the ps and then press the "On" button on the computer. This will discharge the caps in the ps. Be careful opening a ps.

If you're going to open the P/S, my advice is to install a new fan. It's easy to do, I just splice the wires to the old one, takes 5 minutes.
