I have a Radeon 9800 where the fan fell off? Is this something I can fix or replace? I still have the fan rotor.

No, but I do see fans for that card being sold on Ebay often. Some of them are the trapezoid heatsink, some of them are aftermarket ones that are a lot bigger. Check it out.

i remember i had a 9800pro back in the day
the cooler started to give weird sounds, so i wasted a shitload of money on the card, plus a shitload of money on a vga silencer cooler.

5 months later, i woke up...the pc looked like it turned off...
tried to power on..dead

if i were you i would replace the cooler with the best you can find, and add memory heatsinks too. Plus a 80cm cooler sending air directly to that card.

Try Zalman’s compatible cooler, if anyone still carries the old stock. It’s what I got for my Radeon 9800 years ago, back when I was still using that machine. The damn OEM cooler only lasted a year before vibration city.

In case you have to replace the entire cooler, the radeon 9800 has a metal "frame" on the substrate. The problem is, it is thicker than the actual die. You probably have to carefully remove that to get good contact between die and cooler.

If you want to replace just the fan not the whole heatsink/fan assembly, often 30 or 35mm fans will work. Look for the caseless type on ebay (just the fan rotor without a surrounding frame), they are usually meant to be glued on in the empty space left after removing a failed fan. I have repaired several video cards with this type of fan, mostly Geforce2 and Geforce3. They usually come with a piece of sticky tape at the bottom but I find that is not secure enough; I usually remove it and apply a drop of cyanoacrylate instead. It's stronger, and if/when the replacement fan fails it still won't be much of a problem to remove (heat gently with a hair dryer, that softens the glue enough to remove it without damaging the card). Been using cards repaired this way for several years with no issues.
