Replacing the heatsink isn't too bad. Rather than tilting or snatching, you could try gently twisting the cooler to get it free from the processor.
Yes, you could use any 92 mm fan (preferably with a 4-pin PWM connector), but you may have a hard time securing a standard 92x25 mm case fan to the heatsink (zip ties can do the trick).
