If you want an electric fan, you should take the engine-driven fan off and put the electric fan on the backside of the radiator.

Magnum is correct. The best combination would be a puller electric fan mounted on the engine side of the radiator with a shroud. You could leave the engine driven fan on if you want but all you will be doing is using horsepower to drive it. It won't help in cooling the motor with the setup I've described.

What have you done to figure out why it's running hot at high RPM's? What kind of motor? Is it Stock? Does it have a fan shroud now? Is it running lean which will cause it to run hot? Just some info we need to know...

There is a limit on how much air that can go thru a radiator. Also in my opinion, having a fan in front of the radiator, actually limits that amount of air that can pass to only what the fan can push.

Like was said, you need to look at the cause of the overheating problem. If you dont have a fan shroud, get one. Have the radiator checked for proper flow. Is the radiator the right one for that set-up? Check your spark plugs to make sure the engine isn't running lean. Is the thermostat the proper one for that engine/set-up? Was the engine bored out too far for that block? Is there too much grille blocking air getting to the radiator? Find the cause of the problem, then you can fix it.

Overheating is a symptom of another problem. Don't treat the symptom, fix the problem.
