My c70 is blowing some serious hot air out the back of my rig and i'm looking to cool things down. What are some good 140MM options for case fans? would running positive pressure be affordable and good with this case to minimize dust or no?
Thanks for the suggestion! Further review of my case and the airflow situation I want to step up to make sure I'm fixing the right things. Also didn't realize why the front intake was so weak, apparently there is a spot for fans under the front plate. Budget is about $125 I can go over if needed if it keeps my hdds/video card adequately cooled.

Stock Case Fan Spec:
Air Flow - 44.1 CFM
Noise Level - 23 dBA
Operating Voltage - 12
Max Current Draw - 0.12 A
Static Pressure - 0.91 mm/H20
Fan Speed - 1200 RPM

Available Fan Mounts:
Front 2x 120mm intake
Drive Cage Mounts Behind Front 2x 120mm fan mounts
Rear 1x 120mm exhaust fan
Top 2x 120mm/140mm fan mounts
Side 2x 120mm/140mm fan mounts (1 is blocked by heatsink)
Bottom 2x 120mm/140mm fan mounts (1 is blocked by PSU

Current Fans:
Front Intake 2x None
Drive Cage: 2x Stock Fans
Rear 1x Stock Fan
Top 2x None
Side 1xUNF-S12A ULN , other blocked
Bottom 1x None 1x Blocked

Current Plan:
Fan Controller: http://www.frozencpu.com/products/8...annel_Rheobus_-_Black_FC-2.html?tl=g47c17s286 (looking for suggestions, want to daisy chain two fans per switch/knob for front and top)
Front Intake: Do I need something here with significant pressure to get through the filter?
Drive Cage: 2x Stock Fans
Rear:1x Stock Fan
Top: Not sure yet
Side: 1x http://www.frozencpu.com/products/2..._RPM_SY1425HB12M-P_120mm_Fan_Mount_Holes.html 1x blocked
Bottom: 1xUNF-S12A ULN

The stock fan's are pretty weak in general, but are they worth keeping to help pull air across the hdd's coming from the front intakes, as well as the rear? Or would it be worth replacing the rear with something stronger as most the heat is currently escaping this route.

Appreciate the help and guidance!
set up like this?

yes they suggest that you use SP fans against resistance and AF if no restrictions in front of them.

push with SP fans pull with AF fans is a standard suggestion.

The only thing not on that picture is the side panel which I can squeeze 1 120/140
what cpu are you using? depending on what your going to do with it will depend on how much you need to spend.

ive heard that making the top rear exhaust an intake below a radiator can improve temps :)

also how long have you had this pc maybe it just needs de-dusted lol
Ive got an i5 6600, probably wont be OC'ing this time around, and a r9 390.

My primary concern is making sure those HDD's stay at a decent temperature. It's brand new case, there just isn't much airflow in I think. It's also air cooled with an EVO212, so no radiator for me.

they might be out of stock but use that idea and check with your own retailer.
Thanks for the suggestion. So probably best if the noctua is placed on the rear or top then?

Also the frozencpu links you gave don't work for me.
those are your links :)

your not ocing so you need good airflow you dont need to spend lots just make sure all cables are hid and not haning loose in case making resistence and an intake from the front and bottom forcing air out the top and rear is the most common and effective method the fans have arrows denoting which direction the will blow air point them in for intake and out for exhaust with all that done you should have an improved temp with your new fans installed :) shop around for fans that you like and feel comfortable with make sure they have high static pressure for SP and good rpm for airflow AF fans the corsair dual pack are good but not the best
Went ahead and pulled the trigger on buying through amazon for everything. Let me know if I did anything dumb :)
Used the same case for my Full Metal Jacket build. Noticed that i couldnt mount top fans in push configuration because they mount to close to the mesh ,creating lots of noise. But u can over come that by using spacers to mount fans a lil farther from the mesh top, i think. Defenitely need two front fans for good air flow,combined with the two hdd cage fans should help a lot. I removed the front filter because it is pretty restrictive.
how have you got on? have the mesh created a problem for you? I did not for see that problem :( my apologies. SP fans should help with the resistance from the filters instead of AF if the filters arent removed.
Thanks for all the suggestions! New fans installed and the temps are way down. The positive case pressure is also very noticeable. Glad I got the fan controller because those sp120's are loud, especially the side one.
