How much HP does a clutch fan use?

If the fan is required the clutch kicks in and the fan uses maybe one or two HP to turn it. If you have electric fans, your engine must drive the alternator to provide the electric power for them. This might add up to one or two HP also. via

Are electric fans worth it?

Although they will place an additional draw on the electrical system, they are a more efficient alternative to mechanical fans and don't cause the dreaded parasitic horsepower loss. Here are a few other advantages of electric fans: Consistent cooling—they maintain their airflow at all times. Reduced water pump wear. via

Do electric fans cool better than mechanical?

We'll jump right into the heart of the matter: An electric fan is the better performance solution, freeing up maximum horsepower and mpg. But it's not always the better cooling solution. The full answer to this question is that both electric and belt-driven fans have their place. via

Does an electric fan have a clutch?

Mechanical Fans

Clutch Fans have fixed blades. They require a coupler to engage and disengage the fan. This coupler is called the Fan Clutch. Flex Fans do not need a clutch. via

Do electric radiator fans work?

A radiator only works if there is airflow through the radiator core. An electrical fan provides constant airflow even when the engine is idling, when your engine needs it the most and since they are electric, they do not affect engine horsepower or fuel economy. via

Can you run a fan 24 7?

Yes, for nearly all household electric fans you can run them 24 hours a day, 7 days a week. Electric fans are one of the most reliable (and affordable) electric appliances around. via

Is it expensive to leave fan on all day?

A fan costs around $0.02 to run. That means that it only costs around $0.25 to run a fan for a whole day. Running a fan is super cheap, especially compared to other appliances like air conditioners. via

What temp should electric fan turn on?

To check the temperature at which the fan comes on, turn the A/C off and keep the engine running until it reaches normal operating temperature. Most fans should come on when the coolant reaches about 200 to 230 degrees. via

Does the fan cool the engine or radiator?

The radiator fan (or fans) pulls cooling air through the car's radiator. Positioned between the radiator and engine, cooling fans are particularly helpful when the car is stationary or moving at speeds too slow to force air through the grille. via

Should a fan clutch spin when cold?

The fan clutch is responsible for transferring power from the drive belt or the water pump pulley to the fan, but should it be spinning freely when cold? The viscous fan clutch will, with some resistance, spin freely when cold. via

The EPA's Excessive Heat Events Guidebook warns against relying on fans when the heat index is above 99 degrees Fahrenheit. The World Health Organization's Regional Office for Europe similarly cautions that “at temperatures above 35 [degrees Celsius (95 degrees F)] fans may not prevent heat related illness.” via

How far can you drive a car with no radiator?

How much CFM do I need for a v8?

CFM Rating

Engine Size Minimum Fan CFM
4 cylinder 1,250 cfm
6 cylinder 2,000 cfm
Small 8 cylinder (under 302 c.i.d.) 2,500 cfm
Large 8 cylinder (302 c.i.d. +) 2,800 cfm +

Do 3 blade fans work as well as 5 blades?

The difference between performance and noise level between ceiling fans with any number of blades is negligible. via

How does a car works with two electric fan in front of the radiator?

Electric fans are found in the front part of the radiator and are also referred to as “pusher fans”. These pusher fans receive the air which comes through the grille area. Eventually, they push that cooler air over the radiator area. The fans which are found in the rear or at the back are referred to as “puller fans”. via

Should a radiator fan push or pull air?

Use an electric fan.

Preference should be given to a "pull" vs. a "push" fan. Mounted on the engine side of the radiator, a pull fan does not interfere with airflow at highway speeds. All shrouded fans should be on the engine side of the radiator. via
