So to add something other than comedy/stupidity, I bought a SPAL fan whick is pretty silent and feels strong. I don't have anything to compare it too.

Just check YouTube reviews of SPAL vs Chinese generic fans, the difference speaks for itself.

Not particularly scientific but...

wow, that's a big difference :shock: , thanks.

I wouldn't trust the cooling of my precious rotary to a 'love you long time' far eastern ripoff fan, Spal it is then th:

I think most aftermarket fans are reversible.

I'm surprised at the eBay flowing same as the Honda fan. Problem with the eBay fans is, are they all equal?

When the Spal fan diidn't work the naturally air flow through the engine room will be reduced so you can get heat peaks iin the rear engine housings.
Test airflow visc vs Spal are more interesting. Any numbers ?

Gents,

It's worth look at Revotec fans and fan controllers.

I've fitted their stuff to the rally car and it works well.

I can certainly understand your logic here. The viscous clutch fan is constantly moving air so the temperature of the coolant at the bottom radiator outlet should be lower than would be the case for an e-fan, which only comes on when above a certain temperature.

HOWEVER

This would only apply at temperatures well below the e-fan set point, and only while the vehicle is stationary or at low speed (since when the e-fan is off, there is still airing moving through the car). Under these conditions slightly higher rear engine housings aren't going to materialise, because the engine won't be under load.

AND

None of this actually happens with a properly functioning bypass thermostat. The factory thermostats all being to open at 82'C. At that point, the radiator inlet is fully closed and the bypass is fully open, meaning ZERO coolant is entering the engine from the bottom radiator hose - it is only being recirculated throughout the block. The thermostat gradually opens from 82'C to fully open at 95'C. At the same time, the bypass gradually closes. In doing so, it meters the proportion of cold water coming from the bottom radiator hose and the proportion of hot water being recirculated, so you end up with a nice even temperature distribution.
