Do they make any nice 120mm LED fans with CFMs around 80 or higher? I have not seen any more than 70 myself. That's a shame

I don't even know of any clear 120mm fans (w/o leds) with good cfms.

Well if you are looking for just high cfms there are plenty of options over 70cfm. Here is one that pushes 131cfm:

Here is a quieter one that is 108cfm:

As for fans with leds well yeah I never see high cfms fans with leds either.

There are plenty of 120mm fans without leds available that push way over 70cfm, of course. I think the issue with the combination of those two is that led fans are typically catered to the 'shiny looks' people, rather than the performance enthousiasts.

Yeah Right now I'll settle for even just a clear 120mm fan with high cfms. They really should make led fans with higher cfms. Just because you want performance doesn't mean you can't make it look good at the same time

they cant make fans with really high cfm with led cause the led get there power from the rotation of the fan blades to much and u will kill the leds just take an led fan and hit it with a can of air for a few seconds you will see the leds light up

Well voltage to the fan is going to be 12V (unless you do a 7V mod or use some fan controller). I don't think the voltage is dependent on how quickly the blades are spinning. At least that's what I've always assumed.

It wouldn't be too hard to design a fan which got led power from the 12V line directly instead of based on the fan speed.

Thanks Hookem, but like all the one's I've seen, they are just under 70 CFM max. I have yet to find any that are high CFMs > 80

How can this be the case when i can stop the fan with my finger and the led's are still lit up? The fan blades spinning do not provide power....and ive never heard of that compressed air or anything. Led's take a very small amount of power....much less than a fan requires....so even if the led was still taking power away from the motor....it wouldn't case a drastic reduction in speed.
