Case Airflow - Any problem?

post #1 of 21
Thread Starter 
I'm currently using Lian Li Lancool Dragonlord PC-K58 Case

The below picture shows the current case setup:



I'm using:
- 2 x 120mm Noctua NF-P12 as H60 RAD fans (Push-Pull Intake)
- 2 x 140mm Yate Loon D14SH-12 (Top Exhaust)
- 1 x 140mm Lian Li 1000RPM Fan (Top Front Intake)
- 1 x 140mm Xigmatek CLF-F1455 (Bottom Front Intake)

As you can see from the above picture, H60 is taking in hot air coming out from the graphic card and PSU.

Is there any problem if I were to change my current fans setup to the following?

No but you'll get a lot more dust coming from the top.

That's funny, your first picture is EXACTLY how my air flow is. So because of this I'm interested to see if you get any temp change by switching the fans around. But I don't think you will.

Change the top fans to exhaust!

My top fans definitely have to be exhaust if I were to set my H60 as intake else it will be hot like oven with all the hot air trapped in my case.

What I'm thinking is to change my H60 as exhaust instead and my top fan to intake. There are two advantages which I can think up of in doing.

1) Hot air from H60 will not be blown into my case but out instead which will in turn help keep my components (e.g. Motherboard) cool and stable.

2) H60 will not be drawing warm (due to mixture of hot air from graphic card & PSU) air but cooler air directly from the top intake fans instead. Top intake fans are very close to the H60 RAD.

However, I'm not sure how will the airflow be at the bottom of the case.

I think I will try switching it around and post the result here later if I were to do so.

I would leave your top fans as exhaust and change the fan near the CPU (back top) to exhaust. This will keep the flow going from front to back as well as bottom to top.

If you have all that intake, that one H60 fan isn't going to be able to handle all the exhaust it's going to need to do and I would think it is just going to cause the hot air to be trapped in your case longer and/or cause your fans to run at a higher speed, at the very least increasing noise.

Do this and compare temps. You will probably be pleased. From what i understand the K62 does not have top grills, just plastic louvers. Correct? If so, just put some filters on those top fans. You get cooler air that way.
