Clutch Fan Vs Electric Fan

Clutch Fan Vs Electric Fan. Clutch fan pulls well at idle, then clutches and floats/freewheels when road speed is high enough to provide the needed air flow or engine rpm goes higher than the fan's peak efficiency rpm. The electric would also give me the ability to control temp better.

After a couple of 220 temp readings i yanked them out and switched to a thermal fan clutch. Serpentine belts are another thing, that i'm not sure if its worth the hassle to change to. There are two main types of mechanical fans:

I had an electric fan on mine twice. I’m not in for that.

I've batted the idea of an electric fan around too, and still might, but haven't yet. These electric fans do a great job at pulling air through the radiator and do not tax the motor for horsepower and torque.

Disconnect the wiring harness from the fan clutch assembly. However, flex fans can be noisy and annoying for driving around town.

Go to electric fan (s) plus an electric mesiere 53 gal electric water pump. I would make sure you adjust the fan on/off temps in your tune to match the thermostat installed in the truck (good time to also.

The pros are better mileage, quieter operation, smoother feel, no more possibility of the clutch fan destroying your cooling system if it goes awol, and easier access to your cooling system in the engine bay. A clutch fan is belt driven by your vehicle's engine whereas an electric fan is powered by your vehicle's electrical system.

With the cluch fan there is always a minimal load even if the cluch is disengaged. There are two main types of mechanical fans:

With the cluch fan there is always a minimal load even if the cluch is disengaged. However, the fan’s clutch never fully disengages—it keeps always spinning at about 30 percent of the water pump speed.

The power consumed by a clutch fan is different when tested on a dyno with the car/engine stationary than it is if the car is actually in use, running on road, at speed. When my fan comes on though, i notice that my tensioner jumps due to the added load on the alternator.

When mind would kick on the headlights would dim and the motor shook alot more. The ultimate choice is the black magic electrical fan.

Just thinking a clutch could free up some performance, but if it’s only a couple of hp. Can be independently controlled of the engine, more reliable, and dont weigh down the water pump bearings.

Also, Flex Fans Tend To Make More Noise When The Engine Is At Low Rpm.

Your stock electric fan engages if you have the heater or ac on or the moment your temp goes above 210. Clutch fans are controlled by a thermostat and utilize a clutch to engage or disengage the fan at a specified engine speed or temperature. When compared to an electric fan, fan clutches are quite inefficient.

Z4M Uses An Electric Fan.

I don't have cfm numbers, but from much experience the 17 thermal clutch fan will pull the most air and eat the least amount of power for a mechanical fan. When mind would kick on the headlights would dim and the motor shook alot more. More headache than what it was worth.

At Significant Road Speed The Air Flow Flowing Thru The Radiator Actually Drives The Fan Blades Like A Wind Turbine And Adds Spinning Force To The Clutch Fan And Water Pump.

They move more air for better cooling. Electric fans cool faster and are more efficient. However, they pull more horsepower at high rpms than other fans.

Electric Fans Don't Consume Horsepower.

The power consumed by a clutch fan is different when tested on a dyno with the car/engine stationary than it is if the car is actually in use, running on road, at speed. A clutch fan is belt driven by your vehicle's engine whereas an electric fan is powered by your vehicle's electrical system. Unlike a clutch fan, they turn at 100% of the water pump speed.
