Can I run this 27mm edf on 3s?

I think I read someplace a while back that I shouldn't run it at 3s.

I own this exact 27mm EDF.

What will happen if I run it at 3s? I'm using a 30 amp ESC to run the fan.

Thanks.

30amp esc may be over-kill as this fan draws under 6amps max.

You should also take a look at the reviews, seems some may not be well assembled or balanced so wherever you read do not use on 3S was on the money...as far as what will happen, im betting the fan will grenade itself before the motor cooks.

I'm only drawing 2.2 amp full throttle at 8 volts with this fan. Why am I pulling so little amps compared to the specs at 5 amps?

Couple of possible reasons:
. Your batteries are not delivering?
. There is something faulty in the motor?
. Your ESC cannot manage the RPMs that 11,ooo kv motor 'could' generate
