Case fans upgrade

[Ov3erclock3R]

Well like it says in the title, i have a coolermaster cm690 II and i recently turned my psu over so it sucks in air from inside of the case because its on a carpet so i dnt want it sucking in dust, so i want couple extra fans sucking in fresh air. in the front is the standard 140mm which ill probably put in the roof and i want to put 2 high airflow low db fans in the front and then ill mount the gpu bracket that came with the case so i can have another 80mm fan blowing just above the psu and right on to to the gfx card any ideas as to what fan i could use for that ?.

My front fan spec is 140mm, 1200 RPM, 60 CFM, 19 DBA preferably i would like 2 80mm fans that suck in more air and maybe around the the same db, can anyone give me any ideas of what fans to get because i have no idea as there are soo many fan out there,

Thanks.

Correct me if I'm wrong but isn't the front fan slots only able to fit 1 fan, with the ability to move it up and down.

EDIT: Do you want LED fans or regular ones?

I'm not 100%, but I THINK that the bracket for the graphics cards will only allow you to get an 80mm fan that's 15mm high due to clearance with the side panel. If that's the case than your forced to get a CoolerMaster 80mm Slim. But if you can mount a 25mm thick fan than go for a Noctua NF-R8 or an Arctic Cooling F8 if you're wanting to save some money.

EDIT: For the other fans just bolt on some Noctuas if you don't care about LEDs or UV.

Im pretty sure you can remove the front 140mm fan and put two 80mm, but i dnt have a clue what fans to get.

I find the enermax magma 120mm more cost effective
