Reddit reviews Corsair Air Series AF120 LED Quiet Edition High Airflow Fan Single Pack - Red

http://www.amazon.ca/gp/product/B00F6S10MI?psc=1&redirect=true&ref_=oh_aui_detailpage_o02_s00 The fan ran me $15, so your damn near right

Anyways, is there a difference between intake or exhaust fans? Or are all fans intake/exhaust depending on what direction you face them? And how many fans can you add to the bb931? I'm sure there is a limited amount of space to plug into?

And this was the one I was looking at buying https://www.amazon.com/gp/aw/d/B00F6S10MI/ref=mp_s_a_1_5?ie=UTF8&qid=1499312269&sr=8-5&pi=AC_SX236_SY340_FMwebp_QL65&keywords=pc+intake+fan&dpPl=1&dpID=511AmZVcPML&ref=plSrch

Thanks for the help!

I'm thinking about installing some extra case fans for more air flow. I have a couple questions:

-Are there specific places on the case where I should orient the fans to be intake or outtake?

-Are there places on the case where I should leave fanless for any reason?

-Is purchasing a fan controller a good idea? If so, any recommendations?

The fans I am going to buy (I was thinking of getting 2): http://www.amazon.com/dp/B00F6S10MI/?tag=pcpapi-20

Damn, that's sold out on the english newegg, on amazon as they're similar prices, which would you recommend? The cooler master one - http://www.amazon.co.uk/dp/B003VUN8GE/ref=twister_B00KMUJP9A?_encoding=UTF8&psc=1 or the corsair one? - http://www.amazon.co.uk/Corsair-Series-AF120-LED-Edition-Airflow/dp/B00F6S10MI/ref=sr_1_2?s=computers&ie=UTF8&qid=1419833707&sr=1-2&keywords=corsair+red+led
