NO.
You can use many fans that are SIMILAR such as case fans, but for optimal cooling you need one optimized for "static pressure" due to the way it shapes the air and forces it through the radiator.
A great case fan is not a good radiator fan and vice versa (though some are fine at both).
*If you use a different fan and it's fairly quiet, and cools well enough then fine. Otherwise look for a proper fan.
