Will this provide good airflow? It will be a define r5 case and the drive bays I highlighted in yellow i will be removing. I will be using 4 140mm fans. These: http://www.newegg.com/Product/Product.aspx?Item=N82E16835553016
Some specs:
i7 4790k
g.skill ripjaws 2133mhz 16gb
strix 970
wd black
intel 730 ssd
asus maximus hero 7
seasonic 660w psu
asus wifi card
e.c.t
I would put one intake in the front and one on the side panel pointing at your graphics card. Two exhaust out the top or one out the rear and the other out the top closest to the rear. You want to go for a balance of cfm moving through the case. Creating positive or negative pressure tends to create more noise and turbulence. That, and my other rule is only put intakes on area's that have filters. Dust build up will kill your components before "bad" airflow will.
Ideally two front intakes, one side intake, and two top exhaust and one in the rear. However that would require two more fans. You will probably get lots of differing opinions. Dust will kill your components before bad airflow, so only use filtered areas for intake.
I completely forgot about balancing out the air pressure thank you! how about this then One pulling in from the front one pulling in from the side one pushing out the back and one pushing out the top or do you think that i should get the two extra fans and do what you suggested? If I go this route (the two extra fans one) how will that effect the noise levels with two more fans?
Thank's!
That configuration sounds like the best option with 4 fans. You should be OK with just the 4 fans. (you can always order two more later if you don't like the temps) If you have a pc running right now, you can download an app from Google Play. It's called sound meter. Use that to gauge the sound output of your current rig. Those fans are rated at 19.2 So with four of those fans, I am guessing it will idle around 40-50 dB (just a guess)
Thanks for the help man and if I find it's a bit too loud I can also switch to be quiet silent wings. Thank you, your the best!
well thats the idea, but
i don't like those cases anymore, they really fail to provide good airflow.
better solution would be
sorry for poor paint skillz ;)
point is, cold air is heavier than hot air. So you'll gather colder air lower to ground than higher.
Also you don't want to get air from top as you'll take some of your ottake.
also to explain why this is better solution:
You'll have much more heat to dissipate from memory, cpu, and gpu.
This is how I set up my airflow. It's probably a turn off for some of you, since the major intake is from the radiator, but it doesn't get as hot as you'd think. And my temps are great.
GPU never breaks 50c, CPU never breaks 65c, VRM heatsinks are cool to the touch, and RAM is the same way.
I don't like having intakes at the top, because heat rises.
thanks for the help guys, i suppose when i build my pc I will have a fiddle around with the fan layouts and see what works best and if the temps still are not comfortable I will buy a few more fans and see how that works. Thank you!
In regards to
This is true, however the stack effect isn't really as important in PC cooling as you would think. First off, the greater the difference in hot vs. cold, the greater the speed of air movement. When air cooling, the goal is to constantly remove and replace the air in the case before the air has a chance to heat up. Once the air heats up enough, the stack effect starts and in essence you have failed in cooling your case appropriately. Basically what I am saying is, if you have "good air flow" you don't need to worry about the stack effect because the air never heats up enough to make it happen at a rate greater than your fans can handle.
I finally understood this when I started building servers that were being stationed in the desert.
yeah, thats why its good to dump all that hot air somewhere else. (tubes 4 the win)
also its good to have it lying on cold floor tiles, as tiles will serve as a cooling heat-sink for air ;)
Speaking of "cold floor tiles" I know of a guy who laid 200 ft. of copper coil in his basement and poured a new slab of concrete over that. He hooked up is water pump to that and had a completely fanless earth mass cooler. I thought he was a complete genius!
;D i love your 'guy' who did it already, but did it actually work? (you wrote "I thought")
great!
but i myself would prefer to have it in river bed or lake bed. Still no resources no lake, no river, no private land to build :*(
one more question if I put 6 fans in my case with a maximum rpm of 1200 but I want to run them quietly would it be fine to run them at 800rpm (or less)?
thank's!
I really doubt you will have a problem with that much airflow, even at low rpms. I could be wrong. You will only know the answer to that by doing it and monitoring your case temps.
