My intel cpu fan recently broke so I ordered a new one to use. Although my intel cpu has some dried thermal paste on it. Will it be ok to use for the fan? Or do i need to scrape it off and apply new thermal paste

Scrape it off and re-apply. The bond wont be as good as new thermal paste. Failure to do so would result in terrible temperatures.

No, don't scrape anything. Use appropriate solvents.

Ah didn't mean it like that, just use a lint free paper towel or cotton swabs with a bit of isopropyl alcohol.

Take a jackhammer to pound that dried thermal paste off, then submerge the CPU into thermal paste for around 2 minutes and insert into the socket.

Or simply use alcohol and water to dissolve/wipe way the dried thermal paste from both CPU & heatsink. Then apply about a small pea size worth of thermal paste in the center of the CPU and spread it around before putting the heatsink on top.
