How's my airflow????

post #1 of 10
Thread Starter 
Hello everyone,
I am not very sure if this is the best way to for optimal air flow. If you have experience in this field, I'd like to hear what you have to say about it. All my fans are 120mm except my blower. Thanks

Oh, idle is 64℉ and full load is never over 108℉

looks like you just need to flip your one top fan to out

Hot air naturally rises, so I imagine that top fan blowing down/in might be fighting with/disrupting it a bit. I see why you did it that way. You were tring to directly feed the CPU cool air, right? I imagine it's still disturbing the rest, and the intake from the front should be enough. You can experiment and reverse it's flow, and if CPU temperatures don't go up much, it's not essential for cooling it.

Come to think of it, better than reversing it's flow, you might want to outright remove it instead. The reason being, hot air will rise anyway, but you don't want to steal from the pull the air directly going to the CPU. That's just a guess though. It might be different in practice. I'd say experiment around with that one fan, both switching it and reversing it. Go with what's best. If it works best as is, stick with it I suppose.

The rest looks good.

What he said.

But more important than the number of fans going in arbitrary directions, just be sure your input cfm is equal to your output cfm, and you can draw psuedo-streamlines from intake to exhaust.

You could also take out the rear-top exhaust and block off that area, and keep the front-top as intake. Many see temp drops, others don't. YMMV. Other than that, solid traditional airflow. If you're gonna use both top fans, make them both blow in the same direction, or you'll get some positive feedback.

Remove the rear top fan and block that space. It is compromising your top intake, which was an excellent choice on your part. People who have switched from top exhaust to top intake have seen 3 - 5c drops in cpu temp.

Remove your rear grill and fan. Let air exit naturally.

There. We have removed two fans and your rig will be quieter.

Here's my airflow:



You can see that we agree on the basics.

Interesting! This gives me some ideas for the airflow in my secondary PC that I'll have to do a thread on (I already did one for my primary PC so I may as well anyway). I was thinking of trying something similar enough to what your picture shows.
