I did look into it but it requires a backplate for LGA775 mounting
which is not an option
You didn't mention the push pin mount in OP... This is one of the better push pin mounted coolers that are low and quiet, the stock fan is pretty loud though(shouldn't get to full RPM though, comes with a PWM fan so only speeds up when needed).
