Side Fan

post #1 of 10
Thread Starter 
Wouldn't a side fan mess up your airflow? Because you want it to go from front to back, would the side fan be causing it to mess up your air flow?

Hi.

Yes. There is an added turbulence factor.

But, sometimes one has to weight the benefits against the cons. For some systems that are air-cooled and overclocked a side intake over the CPU and/or GPU can help.

See im looking into getting a new case, the TT Armor, the one without side fan is $150, with is $160, but im going to go for good airflow, and trying to get my air from front to rear, and some escaping from top, the side fan seems that it would mess it up. ATM i got a 120mm in my drive bays, pushing air to my cpu, and my cpu is pushing hot air to the rear, and it blows it out. But when i set a side fan on it, it didnt get any air going to the cpu, and temps went up about 4c, not a big issue, but trying to find a way that i could get good airflow with a side fan

What CPU cooler are you using?

Do you want airflow directed at your CPU or your GPU... or both?

If adding a side fans increases your temps, then do you really need it?

...sorry... perhaps I am not understanding your question.

I guess the bottom line is: if it ain't broke, don't fix it.

No offense intended, but I know that many peeps here (myself included) get caught up in the obssessive/compulsive nature of our hobby and sometimes it needs another member to clear the air.

In that case: Yes. It will add turbulence to the case as the airflow is perpendicular to the main flow that you already have setup.

It will depend on the airflow of the fans and if you have the side fans as intake or exhaust. There is no simple yes or no answer.
That being said, generally having just a front to rear flow (and up) works very well in most cases

That's a great answer. I have the Armor case, and from practical experience adding the 25cm side fan dropped my temps significantly (I now water cool, though). I believe the benefits outweigh any detriments.

Add a side fan that doesnt have too much of a high CFM. Since the air flow would not be directly opposing eachother, the air would still get to the back of the case, while cooling the front part of the cooler more. Also, the top exhause will help alot to get the air the side fan blows out. Side fan should also lower SB and NB temps as well.
