What size are ESC Fans?

[AC199]

I have a Hobbywing 120a Xerun and have lost a couple of blades off the fan, making it massively loud now, been trying to source a new one, and its proving difficult as I dont know the size. I realise that I can just measure it, but I'm at work and not at home, I'd like to get one when I'm on my way home if possible.

Any help appreciated.

25mmx25mmx7mm if i remember correctly ..... although you have to change it if using larger cell packs due to voltage or something.
