Questions about this item

Will the 2-pin FS1240-A1042A fit the 4010 mounting holes on my older graphics card?

Yes, the fan is made for 4010 hole spacing and uses a standard 2-pin connector compatible with legacy GPU headers.

How can I confirm the FS1240-A1042A is running correctly after installing it on the 20 mm isosceles mount?

Power the system and verify the fan spins smoothly; the 2-pin design runs at constant speed so steady rotation means it is working as intended.
