Looking for High Performance fan Recommendations

I'm in a severe size constraint for a fan for my M120 powered 107.

The current fan I have is a Flex-A-Lite Low boy.

https://www.summitracing.com/parts/flx-118

The fan is 16" by 3-3/16" deep. This fan worked fine before I installed AC but now with the AC installed it still seems to work fine on 95F days but temperature is running noticeably higher and will climb to about 110C in traffic after coming off the highway. I have not done any testing in the mountains at this time but I'm not expecting the results to be good on hot days.

I found this thread, very informative but no dimensions.

124 electric fan

I also have a friend with a 2005 E55 AMG it uses a 540W fan and he measured it to be 3-1/8" depth. The best measurement he could get with it installed. Unfortunately the diameter is bigger so it would need to be mounted to the radiator core support rails rather than directly mounted to the core. That would loose me about 1/4" which I don't have the luxury of.

So I'm looking for really powerful an really thin fans. Does anyone have any suggestions with dimensions and power ratings.

I would consider the Lincoln Mark VIII fan. Very powerful, somewhat slim and inexpensive. I will be using one on my project-the shroud is almost exactly the same size as original. Got one at the Pick n Pull for $30. Moving lots of air takes lots of current. I think this fan draws 30A at full speed. I can measure mine for size if interested.

Also the controller. This is a well regarded, variable speed controller so you don't have full speed when you don't need it.
constant temperature controllers

Yes definitely could use dimensions. Anything over 16" cannot be more than 2-7/8" thick. 16" fans can be 3-3/16".

Also I have 60 Amps available to run a fan, since my alternator went from ~85 to 145Amps.

Tjts put a Prius dual electric unit on his car and says it works great.

Unfortunately the radiator is a little too narrow for duels

OK I can measure in the next few days. I will try to measure the depth at different points. I guess your engine is 4 cylinders longer now?

Thanks

I have also found that Flex-A-Lite now makes a 3000 CFM version of my 16" fan which is a help and real easy to install, But I don't think it will be the power I need for climbing mountains or driving through Arizona on a 110F day.

I do not have a shroud. I have found a solution with a shroud that has a 2.625 depth but it still only 2500 CFM. That would probably work for my low speed traffic situations.

I'm also concerned about a shroud reducing my radiator effectiveness at high speed as temperature does tend to climb above 70 MPH. In reality the rad appears to be too small so brute force with a fan is appropriate. If I could get a fan at 50 Amp fan and leave the sides open for high speed cooling I think that would be optimum. But a 50 amp fan with a shroud would probably also work fine. Or possibly install passive louvers on the shroud.

Here's the info: 18.5x22" Fan ring 18.5" Thickness at motor=5.5" Thickness at fan ring=3.75"
This fan came in a large luxury car so it should be ample for your needs if it fits. On this car the shroud covered the entire radiator.

It is too big, but that's the kind of info I'm looking for Thanks. One thing I need to look into is if the fan can be removed from the 2005 E55, That might make it thin enough.

There is already the standard 16" 107 aux fan there. Which I had to bend the bumper beam out to get it to fit. Nothing bigger than that will fit. but I may be able to play a little as to when it comes on. Right now I'm using the standard 560SL come on full at 115C or with AC 260PSI. As of now I'm not using low speed on the aux and without measuring the cars performance in motion I cant tell if it ever gets to 260PSI with AC on, but it should if the car AC is turned on with the car still. It is something I will be playing with.

First picture in this link shows the Aux fan installation on a mock up car.
