ok yall check my math 06_f150 is running of the FAL 31163 that can handle 45 amp (info came from their site). It didnt run the fan, he had to run 2 of these, which means he was actually controlling 90 amps Correct? Which would cover it if you go by MGDs info (thanks for the info). So if I get one controller that covers at least 90 amps I should be ok.
Which means if i used the DCC fk-75 (75 amp) I would be cutting it close if i used the 8ga loom (85 amp).
But the Dcc fk 95 running 260amp would be over kill?
I think i can use fk 75 if i go by what snowboarder7710 said, this is followed up later by MGD again
So I think thanks to yall!! Im doing the rf269 fan w/ the DCC Fk-75
also hi-jacked from other thread

You no doubt are aware of an RF-269's spec:
Small fan
Diameter 14.5"
Hub diameter 5.5"
Current (no load) 24.83A
Current under load 26.24A
Starting current 69.64A
cfm (no load) 2797 cfm
Large fan
Diameter 15"
Hub diameter 5.75"
Current (no load) 27.64A
Current under load 36.35A
Starting current 69.64A
cfm (no load) 2964 cfm
Total
Current (no load ) 52.47
Current under load 62.59A
Starting current 139.3A
cfm (no load) 5761 cfm
.......
Note that the specs for a RF-269 are far more demanding that a FAL 270 dual efan assembly. Which is why I'm asking this. At full rpm, moving full rated airflow as installed against a rad (e.g. under load), an RF-269 draws almost 63 amps continuous, both fans running.
Second - For myself, I think for that (very similar) price a DCC constant temperature controller is more robust and a better 'fit' ( not ot mention a better controller). DCC has specifically tested it's controllers with Motorcraft fans, including the RF-269 model. Hence, if yer VSC ever fails, consider a DCC replacement. Their controllers can easily supply > 80 amps of continuos power. Just sayin'.
good luck

ive got the same set up that you installed and i will second MGD's suggestion on the DC Controls controller. ive got the fk75 model and it works perfectly with the set up. these fans take up a LOT of power when they turn on! Ive also got one of the older DC Controls set up for my Mark VIII fan on my expedition i use for offroading. Theyre extremely reliable!

I did the fans on my '08.
Lots of research.
Installed 2010 F150 efans.
(Both fans running 100% draws 66 amp)
First bought the F5 controller. Liked the wet probe included.
Installed the fan and controller, and the controller "fried"
Went right to Painless customer support.
Great support, very honest, said the controller needed redesign.
Gave me my $ back, but no redesigned controller.
That was almost 2 years ago.
I ordered my controller from Delta Current Control;
http://www.dccontrol.com
For the 2010 fans, I would order the FK 75 and the 8 gauge loom.
(my controller uses a dry probe)
Ordered and got my controller within a week.
I would suggest ordering more than a week in advance.

OP
Go with the 75 and the 8 gauge wire.
My fk 85 has a soft start so there is no current spike.
I can hardly even hear them run.
I had great and very timely support from Brian at Delta Current Control.
Good Luck, Happy Wrenching!
