why it's 24V if it's powered via L7812?
Well I dont know which one you have, but mine says
AV-7525M12s
DC 12v
Brushless Made in China
on the back...not sure why yours is 24v ?
The newer version PCB's (I think 1.5.7 and higher) use 24V for the blower to ensure good cooling for the stepperdrivers and especially the MOSFET. Older versions use 12V.
where is it written on the board, which version it is and is there a performance difference between the latest board and say a 1 year old setup ?

I don't exactly know how I found that, and can't vouch for the vendor, etc.
