What way should my CPU fan(aftermarket) be facing?

I have a coolermaster Hyper 212 evo and I installed the heat sink, now I just have to clip on the fan. I have a picture, http://imgur.com/rAAcrhn Should the fan be on the left or right of the heat sink?

Normally on the right, blowing air to the left.

So would http://imgur.com/2JEZcQw be the correct orientation? The fan seems to be blowing air into my hardrives/ssd though so im not sure.

Usually fans have an arrow printed on the side - that's what way the air will go.
