Is it ok to drive with a bad fan clutch?

What’s the difference between standard and heavy duty fan clutches?
Standard-Duty Thermal Fan Clutch: This design turns the fan at 60-70 percent of the water pump shaft speed when engaged, and 20-30 percent when disengaged. It’s made for fans with a lighter pitch. Heavy-Duty Thermal Fan Clutch: This fan style turns the fan at 70-90 percent of the shaft speed when engaged for increased cooling.
Are there different types of thermal fan clutches?
We manufacture four different types of thermal fan clutches: standard duty, heavy duty, severe duty and truck fan drives. Each type is engineered to simulate the performance, fit and appearance of the original equipment clutch that it replaces. All fan clutches are for specific applications and should only be applied for which they are cataloged.
