HAF-X improving the Airflow *56k pictures*

post #1 of 13
Thread Starter 
Hi

today i cleaned my Tower from dust and asked myself if there is any way to improve the airflow or just to get some opinions about my current settings.

feel free to reply, any help or tip is appreciated.
thanks

intake fans:
  • front bottom: 230mm cm stock fan (~110cfm?)
  • front 5.25 area: prolimatech red vortex (~70cfm)
  • graphic card air duct behind the hdds: arctic F12 120mm (~70cfm)
  • top right: 200mm cm megaflow (~110cfm)
  • side panel: 200mm stock (~100cfm?)

exhaust fans:
  • top left: 200mm cm megaflow (~110cfm)
  • rear: prolimatech red vortex (~70cfm)

The air coming out of your top left is just getting sucked back in by the top right fan. Heat rises so just make both top fans exhaust fans. Other than that I don't see any issues. There's really not a whole lot of variations to do in a HAF X. They're designed with a specific airflow pattern from the start.

when i turn the top right intake fan to an exhaust fan then what happens to the the air sucked in from the upper front 140mm in the 5.25 area?
wouldnt it be useless cause it would suck the air from the front to the top without creating a "tunnel" in direction to the cpu fans?

He can also cover the top left fan slot wholetogether for positive pressure case.

Yea, there's not a lot you can do with it.

However: Hot air rises, that's true. But in a case like this, or any case with decent fans and low restriction air goes where you push it.

So I'd say:
1) Both top fans as intake
OR
2) Remove the left top fan (the one near the back of the case) and close it. Keep the rightt one as intake.

Pushing cold air in (especially near your cpu) will give better temps than pulling hot air out. Of course you do have to make sure you get enough air going out. But that's not really a problem because the case is pretty ventilated and that 140 at the back doesn't look like the stock one (which is horrible, threw that out as soon as I saw it and temporarily keep an 'old' 120 in).

EDIT: CBA to open up my case but if you run with 1 top intake you might want to try and place it towards the back a bit more so it blows directly at the front intake fan of the CPU cooler.

Nice cooler btw, have one lying around here too. Looks much better than those dual towers ^^

Please test and compare results. In the past, a user with your case got best results by having two top 200mm intakes - right and left, in your terminology.

If you can find a place that will let you rent a thermal camera, or a friend who has one. You can use that to determine the hot spots in the case to give you an idea. Or if someone has taken pictures of the case with thermals you can use that as a reference to get an idea of where the air is staying inside your case.

Hot air rises is not the statement you should be making. You should be saying air takes the path of less resistance. Your only short circuiting the air flow at the top of the case with the right fan set to intake. You want your exhaust at the top so air can be drawn from the lower areas to the top of the case. Don't worry about the 140mm fan. Your 200mm side panel fan will be more then enough to cover that.
