Viscous coupling fan clutch

In this era of FWD cars, I ended with three RWD's with me

Two of them have a fan clutch voscous clutch mechanism in the cooling system that is powered mechanical ventilator with a clutch mechanism to engage or disengage, based on temperature and cooling requirements.

In Pakistan, most people weld the clutch and the fan works at all times. It has two main drawbacks are:

* Excessive fan noise
* Increased fuel consuming motion

I was looking Aroun the Web to find information about maintenance and care of these mechanisms fan. Stumbled on these two very good DIY's

I just wanted to discuss them and see if there is anyone here done this?

Problem I am facing my Corolla is that the fan is doing most of the time .. can be adjusted.

Wow, pretty useful information I would have given anything for the years before. :-)

But I would still side with the elimination of the viscous coupling and go for a temperature controlled electric fan.
In 2001 I used a very nice Toyota Corolla 1980 (which still dominates my memory) with the Turbo-3C-automatic supply of power (enough power). Although a heavy AC compressor was still there (and functional), my theme was to remove all consuming power all the time. So there was no power steering (hence the pump) and the second to go was the viscous coupling.
Before I used to have two slim fans 2.0D, one mounted on the cooler and the other on the engine side of the radiator channel 4. Both were run at 78 degrees Celsius, or the AC compressor.
The thing ran like a beauty
