System fan sometimes doesn't start, requires manual

Hello. I have a problem with my system fan in HP Pavilion G6-2260sw. It all started with 90b error on startup, telling that the fan is not operating correctly, but it was running. Then after some time it stopped running. Spraying compressed air helped, but only temporarily. Then I discovered that spraying compressed air while the laptop was on and fan stopped, caused to startup the fan. Like it needed some help to get started. But after a while it stopped working. I have a better method now. I have my keyboard detached, so when it doesn't start, I lift the keyboard and spin the fan with my fingers and it starts.
I took the laptop apart, no sign of dust. I updated the bios. But it still happens. I plan to replace the fan. What do you think, will it help? The fan doesn't spin freely when off, you would have to apply force constantly for it to spin. Is it normal for some fans, or should all fans make very little resistance to spinning?
