Watercooling newbie and some help
Yup, The front and PSU intake of the Corsair 760t has a built-in removable dust filter, I already have a dust filter for the 120mm bottom intake fan. They say never block/ put dust filters on the exhaust, so I left the top and rear clear. So yeah, my plan is front 2x140mm(stock fans) + bottom 120mm. then 3x120mm pull for the top and im going to change the rear exhaust.
So, If I understood it correctly. I should still follow the CFM of the fans regardless on how high/low it's static pressure is. If I remember correctly, +/- 20 CFM was the sweet spot for the Positive air pressure, AFAIK.
Intake total = 184.99 CFM
front 2 x 140mm (Corsair AF 140L Stock fans @ 66.4 CFM) = 132.8
bottom 120mm (Corsair AF 120 @ 52.19 CFM ) = 52.19
Exhaust total = 224.78 CFM
Top 3 x 120mm ( Akasa Apache 120 @ 57.53 CFM ) = 172.59
Rear 120mm ( Corsair AF 120 @ 52.19 CFM ) = 52.19
Well, that ruined my plan for positive air pressure lol. Should I get a stronger front intake? Or should I opt for a smaller rad?
OK, so I measured the case for the fitting of the Black Ice GTX Lite 360 + akasa apache in pull. Unfortunately it will be in the way of the motherboard so I really need to get a thinner Rad. From the ones I listed above, which would you recommend? As for the Alphacool, It was overpriced here. more than 1/3 of the original price. The Alphacool ST30 was priced 'ok' but by the looks of it, it's thickness would not be enough to have a decent cooling, Am I right? So the ones I listed were the ones at the top of my list at the moment.
CFM is nothing without static pressure, for example, if two fans can produce the same CFM say 70CFM but one fan has static pressure of 2.7 and the other has static pressure of 1.4 then the fan with the higher static pressure will be able to carry the CFM further into the case and over the components thus giving great cooling performance and pressure.
You are correct in saying you should never have a filter on the exhaust fans but you need them for the intake fans or otherwise the dust will still get in your case..
Don't do a thinner radiator than 34mm and yes, the ST30 is not my first choice for cooling but it has gotten good reviews. XSPC is my company for radiators as i find their radiators are priced right and perform as well as the more expensive radiators and i am sure you could do a XSPC ex360 radiator on top or maybe even a XT45 360mm radiator with three fans in either push or pull as i think the mounting holes are offset to allow for motherboard connectors such as the auxiliary eight pin power.
This is what i would do, 3xAkasa Apaches 140mm, 2 in front and one on the bottom all with filters and 4xAkasa Apaches, 3 on your radiator on top in pull or push and one in the back sending air out the back without filters.
So your pressure would be this.....
Intake
2xAkasa Apaches 140mm @ 89.55CFM = 179.10 CFM
1xAkasa Apache 120mm @ 57.53CFM = 57.53 CFM
Total CFM = 236.63 CFM
Exhaust
3x Akasa Apache 120mm @57.53CFM = 172.59CFM
1x Stock Corsair 120mm fan @ 52.19CFM
Total CFM = 224.78 CFM
