In all the videos I have seen the person installing the fan always makes it face the front of the PC but surely its best to make it face the back where the exhaust fan is so the heat can be blown out? im a bit confused
When the Fan is closer to the front of the case it will suck air in and push it through the cooler and exit out the back of the cooler towards the rear fan which then sucks it out of the case.
Look at the little arrow on the side of the fan which indicates airflow direction: http://www.cryorig.com/h7_us.php
Personally I would recommend the Cyrorig H7 Plus (which has 2 fans) instead of the single fan H7 if you can afford it.
