Gpu fan super loud

[mongo21]

Hey guys and girls,
I have a hd 4870 gpu and it still works like a charm, but when I start my pc up, the gpu fan is SUPER loud. It doesn't seem like a sound when the fan is going super fast but it sounds as if the fan is hitting something or scraping.
In order for it to quiet down, I have to either adjust the fan by keep pressing on it or I have to stop the fan manually, then let it spin, then stop it again until it stops making the sound.

I don't have the money to replace my gpu.
If somebody can help me with this, I would appreciate it.

Thanks

if it sounds like its hitting something, then open it up and see if it is. look for scrape marks on the heatsink, on the fan etc. also if its running super hard, it may be overheating or maybe a temperature sensor is stuffed. perhaps try manually controlling the fan speed via a program

It's not overheating. The temperature stays in 50-70C while running a game such as CS:GO or Skyrim.
Could you tell me a program that controls fan speed?

Sounds like the fan bearing is going on the ole girl .... is the fan at all "wobbly" when still if you press on either end ?

I think its the fan bearing wearing out which on a card that old is fairly likely.

Sounds like the bearings are well past their best, prodding the fan will realign it but won't resolve the issue; the poor old thing is just plain worn out.
The usual resolution would be to replace the card.
Because that's not an option and it's so old, replacing the cooler with an new aftermarket one isn't really cost effective either but there is other options.
1: Do the old cable tie trick: Get a 90 m.m. case fan and simply cable tie it over the top of the old fan. Either disconnect the old fan by cutting its wires or pulling its tiny little plug out of the graphics card socket (you'll need tweezers). If you're a bit braver, take the fan out entirely but be aware, this will entail a fairly substantial stripdown of the cooler assembly.
2: Have a look through E-bay or similar, the HD4870 was a popular card and with a little luck you'll be able to source a replacement cooler for a few (fill in you local currency here). Again, this is a fairly substantial job and you'll need a good quality Phillips screwdriver (possibly two, some cards use REALLY tiny screws) some new thermal paste and some cleaning fluid.
