New Fan for a Phanteks case (6700K OC in mind)

[foxslink]

Hola Amigos,

it’s been 5 months since i built a new PC thanks to your help and now is the perfect time to add a second intake fan, i got a discount code from a company that ships amazon products from USA to Chile , the Phanteks case i bought from them only came with one exhaust fan and i think adding a second one is a good idea, considering i live in a warm city and the CPU is OCable, havnt done OC yet but i would love to try it sooner than later.
I think i should get one of these 140 mm fans or something similar:
Noctua SSO

Phanteks 140m

or maybe a 120 like this

This is the case i have right now: https://www.amazon.com/Phanteks-Ent...r=1-3&keywords=Phanteks+Phanteks+Enthoo+PRO+M


what do you think is best? i cant spend more than 20 usd because i have to include the shipping.

Any suggestions? i think ill go for the PH-140SP, there's the option to get the white blades one , its a bit more pricey though, would match more with the other fan but other than that i dont see much difference/advantages

there is another black version that was available a few hours ago and not anymore, seems similar to the one below, i think they are almost the same

so far this is the most promising

Can't go wrong with Noctua's, its all I have in my Coolermaster MC5 Pro. I had some white Phanteks fans in my Phanteks Enthoo Evolv case, they seemed pretty decent also. Go with the best you can afford. Also, don't get buyers remorse if your 6700K runs a little warm for your liking, they run warm by design, have mine at 4.5 right now and it hits 68-70 on air sometimes. Not what I had hoped for but at least its quiet.
