Replacement fan for ATI 5670

[coldmilk2]

I have a relatively old computer (5 years old) with a GPU ATI 5670.

The fan to the heat sink has been acting up recently. Sometimes it jam up and the GPU overheat. If it is jammed, a small push will get the fan going. Only happen during start-up.

How easy is it to buy a replacement fan? or the entire heatsink/fan assembly?

Is it better that I change the whole gpu card? If so, any suggestion for a good and cheap replacement gpu?

Thanks for any assistance.
