Anyone know the CFM of the stock POS Fan on a Jonway YY250T?

Hey Todd,

I think that is classified on a "I don't know basis" and the fan designer may take this to his grave. Seriously, this fan really blows. It moves a lot of air as I found out when I was bench testing it, but it should as it pulls over 4 amps. Those Panaflo fans you posted about on another thread would probably do a good job if you use 4 mounted in a square configuration in place of the original. That would be moving over 270 CFM.

Ok I am wondering if replacing the stock fan with all new fans might be worth while. I have some 120mm and 80mm fans.

I dont know the dimensions of the radiator off hand so just threw some ideas together.

I was thinking of haveing either the 120mm's on all the time and 80mm's on when temp comes up or the other way around. Or maybe all of them on all the time. Either way will not draw as much current as the stock fan.

What do you all think?

Here are the arangements I am thinking about. I like the top arangments the most.

I believe the 10 to 11 inch dimension might be the max for a replacement. The three 80 mm and two 120 mm setup might work. I think using four 120 mm fans in a square setup might be the easiest way to go even if you have to buy a fan.

I will look at the Dims. I found a place on line to get at 1100 cfm fan that is only 3 amps draw. I may get that. But for now I think I will go with how ever many I can fit in front blowing into the radiator to keep the fan from kicking in until I get a lower draw hi output fan.

Thanks.
