What a crappy weekend . . !!

I dont live where you live !

The fan is only really any use when your not moving and it will fit with the aftermarket cooler and pass air over it when you are stopped if the bike gets hot enough .
I've only had the fan come on when slow filtering or stopped on very hot days in Europe.
The southern warm climate of the Blackpool area might bit warmer than Scotland but not to much

Yeah Speedy, prob ok for your climate. Have a look at Tonys post 33 1/3, thats Brisbane, just a tad cooler than here. 49 degrees just 3 yrs ago, a fan a necessity.

It's an issue but it is not a big deal. With that cooler (or the HEL) the fan will act on the radiator like with the OEM. You may get a little less air flow on the cylinder head. If you feel you want that extra flow, you can modify the mounting brace quite easily.

Ordered the oil cooler Monday morning via the phone and it arrived Tuesday lunchtime.
In my view thats brilliant service..
I phoned them back to say thanks for posting when you said you would..
He seemed surprised someone had bothered to give a verbal pat on the back !

Sign of the times I suppose.

Looks like the same oil cooler I've run for about 50k since my 2nd genuine one burst.

The flange across the top is a good thing as it stiffens the structure of the cooler & blocking air to the fan there isn't a problem. The fan is to suck air through the cooler when you don't have enough airflow from a moving bike, air sucked over the top of the cooler won't do anything to prevent overheating.

My thoughts exactly Hooli re airflow.
Car rads and watercooled bike rads have the fans behind the rads as you say..

with the fan removed there is a lot more airflow over the top of the engine anyway.

The fan on a 14 is 3/4s behind the oil cooler, it can't be lowered as the cylinder head is in the way.

I've never had an issue since fitting one of those coolers anyway & I've done a few* mile since then.
