1100MP Projector Fan Specs

I recently had one of the 2 front fans in my 1100mp projector burn out. Since it was out of warranty i found some friends that can fix it but we don't know what type of fan to replace it with and we cant find the specs anywhere. I was wondering what the specs for these fans are so i can find a replacement, more specifically the power rating for the fan but more information would also be helpful. Thanks
