My GPU fan has been weird for the past few months. Its new because I just replaced my old one with a dead fan. Its not the best GPU but I thought it would get the job done and last me a long time.
Here's the deal:
Past few months, if I bumped my computer or my desk which my computer sits on, the GPU fan would start making a grinding noise. After the computer booted up, it would be fine unless I bumped it again and it would make the grinding noise again.
Today, I turned the computer on and it immediately started making the grinding noise but at random intervals it seemed. A few seconds would go by with the fan turning as normal and then it would start grinding for a few seconds (I looked in the computer and the fan got slower during the grinding)
What do I do facepunch? Do I need a new Fan (I'd rather get a new GPU) is the GPU incompatible with my PSU voltage?
(Incoming computer illiteracy)
Is it possible I just need to "oil" the fan? I'm not sure how to aid to computer problems so please help with any info you may have.
Shifted housing or broken bearing.
Just open it up and see if something is touching the fan.
Nothing is touching the fan. I'll ask my dad about the other stuff though. Hes the one who installed it since I haven't taken my Computer Service and Support class yet.

You have classes for that?
Well the fan itself doesnt make noise so it must be touching something somewhere.
What GPU is it annyway?
ATI Raedon 4300/4500 series
hmm. I was looking earlier and couldn't find any wires touching it. I may have not looked close enough though.
From what you described, it sounds exactly like the fans bearings are shot, it's gonna die completely soon.
Happened to my Nvidia 9600gt just like you described it, I replaced it with a case fan.

That looks ridiculous to me, but if it works... Well, before you go and attach a case fan to your GPU, why don't you try peeling off the sticker and oiling up the bearing a bit? Just make sure you put the sticker back on right.
When this first happened to me I paniced and thought my fan was going to die, I wasted $50 on an aftermarket cooler and installed it, thought everything was going to be fine and the superior reference cooler was now useless, the piece of shit heatsinks fell off the voltage regulators, and pop went the weasel.
-$280.00
I used to be running dual crossfired 5850s, now I only have one. It hurt a lot, it was like losing a testicle. Don't lose your testicle man, oil it up a bit.

Yes the fan does look a bit silly but along with proper cooling paste, the new fan gets it down to about 45C idle which is down from 60C idle with the stock cooling.
Wow, my dad just wants to buy another GPU all together.
well I don't mind him upgrading it... but I did feel morally inclined to tell him the other cheaper option.
Just go on newegg and buy a new cooler.
99% of computer fans don't use ball bearings anymore, and haven't since the end of the 90s. Most all fans these days use sleeve bearings due to their simplicity (just a shaft with a usually one piece sleeve around it and grease.) They start making the WRRRR sound when the friction from the rotating shaft burns all of the grease away. If left unchecked, the burnt grease eventually turns into gritty carbon and will start scoring the shaft and walls of the sleeve, making repairing them very difficult.
You can't use oil to re-lubricate the sleeve since the friction will burn up the oil in a matter of hours. You need something like lithium grease, or gear lube to re-lubricate the shaft.

If only I had known this before my first 5850 started churning....
do any of you know what kind of grease I need to buy in order to fix this grinding?
also, I haven't heard it do it in 2 days now.
White Lithium Grease or gear lube. Lithium grease is much cheaper and you don't have to buy a huge quantity of it for just using a few drops of it.
Make sure it's the stuff in the squeeze tube (home depot has it) and not the aerosol can, since the aerosol has other stuff in it and it usually doesn't work as well.
My dad found some Hobby Lube Dry Graphite lubricant in the garage.
would this work? It said hobby lube so I really worried out when I saw it.
actually never mind. Graphite + Electronics = a big NO NO
Graphite would score the shit out of the sleeve bearing.
