Best electric fans

Just looking for opinions and experience with electric cooling fans. I especially would like to hear from people who live in hot climates. I live in the phoenix area and It's tough to keep cars cool here especially when the're modified.

The radiator I'm using in the car I'm building is an aluminum single core with 1 3/8" wide tubes, and the core measures 31 1/2" X 18 1/2". I only have about 4" to 4 1/2" for fan width. Any suggestions on single or dual fans? Thanks.

I live in ohio and lately its been hovering around the 90's . I have that big black magic fan, its eiather 15" or 17" I believe. It works great even driving around middle of the day. I do have aluminum heads, so that sucks up some of the heat more than cast iron heads do. I use water wetter also, I've read and heard alot of people say it actually helps. If your converter has a high stall then that can add to the heat build up as you drive too.

I had a black magic fan and it didn't work for me. I live in lower Alabama and its very hot. I haven't got my car back on the road yet but I bought a flexalite 295 for my camaro. My radiator has the same width dimention as yours. I have a 454 with a 8-71 so mine is extra hard to cool. I also bought a eldelbrock water pump. The black magic moves 2800cfm and the 295 moves 4600cfm. If that turbo car is what its going on I would bite the bullet and get the 295. Idle is where I had the problem. It just could not move enough air.

Fan

Flex-A-Lite or Ford Taurus. Both pull around 2500 CFM air flow. I have used the Ford fan but am now using a Dual Flex-A-Lite setup because it's "Purdy". It cools my 350 in my S-10 just fine.

I have used Zirgo fans they are 1/2 the price of spal and pull more cfm. In fact the have a new fan 16" that pulls 3985 cfm. And they fit were most fans won't.

i use a fan off of a mustang motorcraft part# rf-86

it is a two speed fan, i trimmed the brackets molded on it off and mounted it in my stock shroud. no cooling issues on a 500 hp ford lightning idling in traffic with the a/c on full blast on 100+ degree days here in houston.

this guy sell them, and has a nice controller for it too:

My experience is that the fans with the flat motors just don't pull enough air to really do the job. Unfortunately, the ones with the motor that sticks out of the back of the fan are tougher to fit into cramped spaces but sometimes you can move the fan around on the radiator so that the motor fits under, over, or somewhere that the waterpump pulley isn't.

The other feature that seems to help are fans that have the curved blades rather than the straight ones.

And of course, the higher the CFM rating, the better job the fan will do.
