Is a Kenlowe fan worth it?

[roamingyak]

I have a 200 tdi defender - with a large intercooler on the front which probably blocks some degree of air flow. On a hot 35 degrees day my temperature gauge does get a few notches higher on a long run.

My esteemed outfitter suggests doing the following:
"The Kenlowe fan fits on the inside of the radiator. I'd have to cut some small slots into your cowling to make some strong brackets to hold it. The standard Kenlowe method of attaching it to the radiator is not ideal.
You can have a switch if you want, but there is an adjustable thermostat that turns it on and off as needed. But it's no problem to add a switch in the cab if you want."

Would it make a noticeable difference on a hot day if I add a Kenlowe fan?
