just did a bit of test earlier..
after going for a good drive.. nothing like stop n go or spirited driving.. just plain/normal A to B drive..
I reverse parked the car, left the engine running and had the a/c on full ON and looked at the gauge thoroughly.. at this time the gauge was sitting on its normal position as it normally does..
kept the engine and a/c on for a good 10 minutes, what do you know the gauge started climbing... not dramatically just slightly higher than the normal position..
I'll have another think about my fan setup.. i might make proper shrouds to cover between the a/c condenser and the radiator.. this will be installed to assist the push configured fan..
as for the pull type.. i'll probably make a proper shroud for it. when time and $$ permits.. but so far i dont think this 14" fan is not moving air through properly..
I remember him installing 2x 12" in pull configuration, but never thought he had issues with them.. I'll keep a close watch on my temp gauge.. Im actually thinking of getting a stock radiator..
fans are definitely pushing air where they're supposed to as i tested them individually after installation..
no shrouds, just installed on the rad.. im cheap at the moment..
according to davies craig site the 10" flows a around 650cfm and the 14" does around 1500cfm
and they do move alot of air when installed..
not saying you're wrong.. my thoughts on this, why would toyota do the same setup on their cars? for example those damn camry's

Carsten has the same problem with his, though he is running both fans in push + full alloy radiator.
One possibility is that at low engine speed with the bigger radiator there also isn't enough turbulence (water speed) through the core to get optimal heat transfer, also contributing to a slightly high temperature.
Carsten has been running his like that for ages, I wouldn't be overly concerned. If you are, get a electric booster pump to improve your idle water flow.

Hi Christian, Have you checked that both fans are moving the air in the correct direction, that is from the front to the rear. They are DC motors and its easy to plug them in with the polarity
incorrect. With one in front and one on the back of the radiator they need to be connected with opposite polarity so that one pushes and one pulls the air through.
fans are definitely pushing air where they're supposed to as i tested them individually after installation..
I have a40mm radiator and it works fine.... These fans, do they floe more but against less static pressure perhaps? Do they move lots of air though the radiator out just out in the open? Also, what are the shrouds like?

U need to have both fans pressurising your radiator or she won't work 2 blowing one way or 2 pulling either or
