Which side of the Thermalright TL-C12B-S fan is the airflow intake?

I'm looking for clarification on the airflow direction of the Thermalright TL-C12B-S fan. Unlike many fan manufacturers, Thermalright doesn't have airflow direction indicators on the fan housing. Can anyone tell me whether the air intake is on the shiny side or the other side with the model number? I'm replacing the chassis fans in my wife's computer, and I'm a bit confused about this.

From what I can see on Thermalright's site, the front of the fan is the side without the supports, while the back has the support struts. So, the airflow goes from the front (the shiny side) to the back (the ugly side). That's where the air is pulled in and pushed out.

TechyNinja42: Thank you! I've assembled a ton of systems, but these little details can trip me up sometimes.
