Help with airflow please?

post #1 of 17
Thread Starter 
Here is my current config in the HAF-X:

My concern is, could the rear 140mm fan be extracting air away from the SP120's to push through the Rad?
Also, would by top rear 200mm fan be a cause for concern for the SP120's on the top of the rad which are trying to extract air away from the Rad?

Thanks for the help and support.

Yes, yes it can. Turn it around to make in an intake, could lower your temps quite a bit.

That airflow seems perfectly fine, you want a front/bottom to top/back flow ideally which is what you have. You could turn round the rear 140mm fan if you wanted to which may yield better CPU temps however it may also mess up the airflow and mean that other components will get hotter.
The top 200mm may be a problem, it could be restricting airflow more than it's helping. I'd remove the 200mm fan and move everything up one, if that makes sense.

^This

Try to remove the 220mm fan in the top and turn the 140mm back exhaust to make it into an intake.

Take a look at these two threads. They can teach you alot about airflow. I learned a ton and have great airflow now.

That sounds great. I will look into this.

Yes, you are right about airflow, but I don't mind a little bit of disruption as long as the temps reduce.

So these are more plans. Take your pick on the best please guy's. Thank you.

I'd go with 1 or 3 too. Just experiment and see which one yields better temperatures, airflow is a finicky thing and you can only find out what works best by trying it.

Is your H100i also set exactly like mine?

These links would then suggest to have the cool air coming from outside the case and into the Rad, but I don't think that would work too well with the design of the HAF-X as the right fan is slightly obstructed by the design style.

Looks good OP.

Thanks, I will test them out!

I will try smile.gif

Edit: I have a 10c diff between 2 of the cores on the CPU. Should I reseat the block? And is Thermalright CF-III as good as the TIM corsair used for my H100i?

+1 to all.
