But also, no, it shouldn't go anywhere near that high on the stock cooler.
Rotating it shouldn't be such an issue, unless it came off badly when you took it off. You did check that there wasn't any plastic film to remove first right? Did you plug in the fan power cable?
Use nail varnish remover (acetone/isopropyl alchohol) to clean off old paste. Any brand or even generic thermal paste/grease is fine.
