While looking for anew inter cooler I noticed a lot being offered with an electric fan attached.
Is it worth while having a fan on your IC ,just putting it out there ??

G'day Craig, I'd say it depends on the intended truck usage mate. If it were for highway use then I'd imagine the scoop would do all the work needed. I'm thinking for low down slow crawling applications a fan would near be essential to stop heat soak on top mount IC's.

I agree with what MB says here. In fact at highway speeds or even general road speeds, a fan is more of a hindrance than a help.
But offroad at speeds below 40kph then fan does help a fair bit then.
I have a fan on my cross country cooler wired to ignition so it is always running. I would forget to switch it on at low speeds if I had it on a switch, and I think it helps with heat soak when stopped at lights etc, it always has cooler outside air flowing through it so doesn't soak up as much heat from the engine.

In theory a fan should help at all speeds if set up properly as standard set up does allow air to flow through all the intercooler as can be seen from attached photo of mine. Back half is dirty from air and dust hitting top of intercooler but front half is as clean as a whistle. Standard scoop & intercooler.
At the end of the day, all you have is yourself and all you need is your friends (and in our case our Patrol)

If I saw your IC I would think only half is being used, be it the dirty side only saying that because with the ARE scoop
there are vanes underneath to direct a pecentage of the air to the front of the IC. With the OE scoop air is forced
only to the rear. Saying that I believe only the Dirty part of your IC is being used, so not very efficient it could be better
The ARE web site shows how efficient your IC can get,, what with a tigged IC to fitting an ARE scoop to even fitting a fan

there has been lots written on this topic have a search and see what you can find,
Depends what you use your Patrol for,,what motor /IC do you have

My cross country IC arrived with a fan fitted. I wired up a in-dash switch so i can manually turn it off or on. As MB said, general driving around town or on freeway it makes sweet f*** all difference with fan on or off. If the cross country intercooler is as good as they say it is, I don't know why it comes fitted with a fan.... But anyway I left my fan on and wired it up.
I haven't yet tested it under crawling conditions though.
However... I have a enormous ARE scoop which scoops up a lot of air movement while vehicle is at speed. So...
My guess is, (and this is only my guess) cars with standard size intercoolers and/or scoops will benefit much more with a fan, than the larger intercoolers and/or scoops. The fan will promote more air flow.

From the info I received when I brought my ARE scoop was the STD scoop
doesnt really do much till you hit 80KPH, with the ARE scoop fitted that drops down to 60KPH
Heat retention would be the enemy, Not sure which is the best way to wire one up.

Hi guys
Thanks for your feedback , I have seen them wired up to a thremocouple fitted to the outlet
of the IC so it comes on when the air temp reaches a certain point .
