Hi Rokas, Unfortunately you cannot get the fan replacement in a shop if you want to get the original cooler. Your alternative is to get an aftermarket cooler. Artic Cooling, NZXT are some known brands you can get.
That is what i was thinking. However looking through those coolers i never once saw specifically club3d r9 270x listed as compatible card. Can i trust cooler will be compatible if it lists r9 270x of other vendor as compatible card? What i am really asking if there is some standard of mounting holes all vendors follow or if every vendor does his own things making coolers incompatible across vendors?
