H220: confused on how to setup airflow

post #1 of 6
Thread Starter 
Hi everyone,

I'll be picking up an H220 later on this week. I have a few questions surrounding the installation and configuration of the cooler as it will be my first water cooler.

I use a Cooler Master HAF X, so keep that in mind. I will also be replacing the stock fans with the Noctuas NF-F12s


Please see attached picture of how I plan to setup my H220 airflow.

My issue with this is that heat rises and there wouldn't be enough exhaust to get the warm air out (just the small 140mm in the back; the 200mm on the side is somewhat low on the case, making it somewhat inefficient in sucking the air out). So if I were to make the top two fans connected to the H220 act as exhausts, this would seemingly fix my issue. However, I would then be forcing already warm air inside of the case to cool the radiator, again, making my cooling inefficient.

Lastly, specifically on the HAF X, would I want to keep my 200mm top fans installed WITH the H220 or would I remove them (the attached picture assumes I would remove them but if this is incorrect, please tell me)?

So can you guys or gals give me some advice as to how to setup my fans? Any help would be greatly appreciated.

P.S. I have had negative pressure in my case for the last 2 years. Would there be a way to keep negative pressure AND have the H220 running in the most efficient way in term of airflow?

Ok. Could you quickly explain why that would work? Like I mentioned in my OP, I'm worried that having the 120s as exhaust will make the radiator less efficient.

im quite sure 2-3 degrees wont matter much at all. why would you want negative pressure, especially pushing heat into the case? that heat and the rest of the air in the case would be stagnant as all get out. and any dust will settle in the case.
only h220 as exhaust and all other fans as intake. but gt ap-15 fans for that h220. cheaper, more airflow, quieter are 3 reasons its better.

My case runs 1 single 200mm intake in the front and 1 140mm exhaust in the back. I run my H220 with 2 fans pushing into the case also. I have seen zero temp changes trying both the H220 fans in either push or pull, intake or exhaust. Granted we have different cases, but don't over think things. Just install the H220 the easiest way. My case came with 2 200mm top fans also, they are not being used.

Fair enough. But wouldn't I want negative pressurce (exhaust CFM > intake CFM) to help expel the heat faster? Thanks in advance. I'm still constantly learning biggrin.gif
