The side with the sticker/supports is the side the air will come out of.

Generally, there are arrows on the sides. Otherwise, look at the concave side of the blades, or where the bracing is. Most of the time air will be blown out that way.

It's for a heat sink so it doesn't have that

What is bracing

 

The bits that hold the fan and motor to the outer frame.

Can you post a picture of the fan? Even ones for heatsinks tend to be standard designs, and they'll have to have supports for the motor and fan.

So air will go towards the bracing or away?

I will when I get home in about an hour so look out for that

Toward the bracing. But even more important, there are usually arrows (2 of them) on the side, one showing rotation direction, the other showing airflow direction.
