Are Flex fans any good?
For high rpm use, flex fans are considered an upgrade over clutch fans. They can be a good choice for modified vehicles turning 6,000 – 8,000 rpm. Advantages include: They move more air for better cooling.
How much HP does a flex fan use?
I’m sure a flex fan takes 5-10 horse but some large electric fans can pull 30 amps. Might be a horse or two just to make that. For the money you can’t go wrong with a standard thermal coupled mechanical fan and a proper shroud.
What is a flex fan?
Flex fans use a stainless steel frame and blades of either plastic or steel riveted to the frame. By design, their blades flatten out at a preset RPM to reduce power-robbing drag on the engine. This is particularly useful on engines running high compression ratios that are more difficult to cool. …
What is the difference between a flex fan and a clutch fan?
Flex fans don’t use a clutch and therefore operate at 100 percent of water pump speed, making them more efficient than clutch fans. Considered a step up from clutch fans, these fans are typically lighter than clutch fans and often feature blades that flatten out at higher rpms for greater efficiency.
Is a clutch fan better than a regular fan?
When compared to an electric fan, fan clutches are quite inefficient. The benefits of a Thermatic Fan lay in its ability to provide constant air flow, improved fuel economy, better air-conditioning performance, cooler engine running and increased engine power.
How much HP does electric fan add?
In a normal pickup situation, even in high ambient temperatures, the electric fan system will only draw a maximum of about 5 horsepower from the engine. This significant savings improves fuel economy, and, in turn, reduces emissions while improving vehicle performance.
How much HP does an electric fan free up?
Are electric fans worth it?
A key advantage of electric fans is increased engine cooling and improved air conditioning cooling at idle, when it is most needed. In addition, replacing an engine-driven fan can increase horsepower and improve fuel economy as the engine drag from turning the fan is eliminated.
What is better clutch fan or electric fan?
Do radiator fans push or pull air?
Electrical fans can either push air through the radiator or pull air through it. A pusher fan sits in front of the radiator. When a vehicle is moving, a pusher fan can obstruct airflow due to its positioning in front of the radiator. A puller fan on the other hand sits right behind the radiator.
What temperature does a fan clutch engage?
At what temperatures do fan clutches engage? Answer: Most fan clutches engage at about 170°F air temperature (about 180-190°F engine temperature). They reduce the temperature about 20°F before disengaging.
Does aircon use more electricity than fans?
Can ceiling fans save energy? Absolutely. Central Air Conditioning (AC) uses around 3500 watts of electricity per day, an AC window unit uses between 600 and 1500 watts and a ceiling fan uses between 30 and 50 watts, so it’s quite a savings!

How does a flex a Lite belt drive fan work?
Flex-A-Lite belt-driven Flex fans feature an aggressive pitch blade design to move the most air at idle. Plus the Flex blades will flatten out at high engine rpm to reduce drag–improving horsepower and gas mileage. What is the max RPM rating on this fan?
When to use electric or mechanical flex fans?
Mechanical Flex Fans. Electric cooling fans are a great option to an engine mounted fan to free up horsepower and better control engine temperature. Electric radiator cooling fans usually switch on when the engine coolant reaches a set teperature.
