I need to buy a fan for my computer case because this one died out. I measured it from mounting holes and it was about 6.8 - 7 inches (it was not very clear). I heard I would need a 170mm but I'm not sure and I just want to make sure that I buy the correct one!

If it's needed the case is a BCC Voyager Mid-Tower ATX
 
Solution
I can't find official specifications for that case model, but I'd say 180mm is the size you need. If you kept the manual, that might confirm the size.
180mm fans are more common than 170mm, but measure the outer plastic of the fan, not the mounting holes. If you don't have a ruler that shows millimeters, you should get one - most grocery and drug stores will have them in school/office supplies.

Outer plastic as in the circular shape?

I measured it and it is 7 inches which is about 177.8mm. What fan size should I buy?
