It almost drowns out the sound of my exhaust which, granted, isn't super loud to begin with. I've been "planning" to get an electric fan for all the right reasons including it being more quiet, but before I do that I need to upgrade my electrical, which means I need to finish my interior, etc. So, in the mean time, is there some flex fan I could use which is not so darn loud? It cools just fine but the noise is making me nuts. Ideas?
Go with a clutch fan.Quiet and its an easy swap.My flexfan was very noisy as well(sounded like a schoolbus)From the front of the car I found my electric fan almost as noisy although you couldn't hear it in the car.A thermostatic clutch fan only takes power when its above a certain temperature.I liked the electric but it didn't cool the car very well and it was embarrassing driving around with the fan belt squealing like crazy

the reason flexfans are loud is because the blades are equally spaced. the factory fans(non clutch fans) are much quieter because the unequal spacing eliminates certain harmonics set up in an equal spaced fan blade system.

I'll add another vote for the clutch fan. I also had a flex fan that was very loud and annoying. I picked up a clutch fan from the local junk yard cheap. It works great. It is quiet and my temperature also dropped. Very easy swap.
One of the very first changes I made to Queenie's 67 Camaro was to eliminte the "Flex Fan" (it sounded like driving in a wind tunnel) ...
Changing to a factory style clutch fan improved the driving experience 100% on that count.
The 55 Effie 460 is equipt with a factory style clutch fan as well.
Even the Mach1 351C has a ridgid steel blade fan (unclutched), but it also has unevenly spaced blades and I don't notice any fan noise there. However, the Mach1 is very loud and obnoxious at it's best anyway
I too would like to know what a suitable donor would be. I can't fit a shroud on my 65 Comet (302) because it has a 15+ inch fan. It sounds like a clutched style fan and a shround may fix my cooling problems. TIA.

I also had a flex fan and I'm glad I changed it for a clutch fan instead. The flex fan create a complete storm under the hood. I used to park it in a very dusty place (mud floor) and it was blowing dust everywhere. With the clutch fan, it warms up quicker too. Too hot isn't good, but neither is too cold.
I wish I knew of a clutch style fan that can withstand some higher rpm. I like everyone else don't have a lot of room. I have tried several different electric setups, none have cooled the car, the flex direct drive mechanical keeps it nice and cool, but it's super loud. Did mavericks come with clutch fans? I'm gonna have to try something soon.
Yes I have tried the plastic flex fan, it's real loud, so loud that I ended up sawing some of the blade off to quiet it up a bit. I have tried a cheap 18inch electric fan, an 18 inch permacool fan that was suppose to move 3000 cfm of air, and a fan out of a 3.8 sable that was suppose to move a ton of air, and it has a fan shroud built in that covered my radiator nicely, still nothing worked for me except the mechanical fan. Hmmm
