As im gathering the information for the fan delete mod more and more questions keep on popping up. I found couple of aux fans with higher CFM and would like to know how they compare to the stock BMW aux fan. The fan i was looking into has following specs : 13Volt
10.0 -/+ 0.5 Amps, 250W input 117W output and it provides 3630CFM....now all these numbers look awfuly big to me. Especially the electricity consumption, what do you guys think ? Will this monster overload my generator really bad ? Stock BMW aux fan specs ?Also there is another fan but its far more expensive....13 Volt, 7.5 -/+ 0.5 Amps, 150W input 66W output, and it provides 3985 CFM.
here are the links:

Not sure why you want to do this.
I bought an M Coupe that had this mod, and replace everything. I just didn't think the mod was worth whatever hp might be gained Vs my engine over heating due to the fan not working for any reason.
With that said, I do live in a rather warm climate.

The only advice I can give on the subject is the fan you listed with straight blades I would not use the one with curved bladed I would use
I have instlalled the straight blade type on cars that were retrofitted to 134a and it made no change in head pressure, the curved blade spal type did make a big diff in head pressure

Thank you guys for advice, ill go with the curved blade fan then. And im sorry i didnt clarify this earlier im not doing this for the HP increase...i already had 2 fans that exploded and im pretty much angry at whoever/whatever might be at fault and i feel like i have to do something to change it, and this mod will be it, i believe. So 01Silber you think that this fan http://www.autotechalarms.com/inc/pdetail?v=1&pid=3600 is a better choice and you dont think it will overload my electrical system ? Thank You.
