Do I have enough exhaust-ing power?

Hello all,

I am wondering if I have "proper" ventilation in my case.

Basically, I have 3 CoolerMaster SickleFlow 120mm fans (rated 69CFM) acting as air intakes from front, side and rear. This leaves me with only a single Thermaltake 200mm fan on top to act as an exhaust. According to their website, this 200mm fan does not move a lot of air (65.3 CFM).

I am wondering, is this a huge problem for my airflow and case temperatures? or should I purchase and more powerful 200mm fan like the CoolerMaster Megaflow (110CFM)? If I did such a thing, would there be a drastic decrease in case temperatures? or only something small like 1-2 degrees?

Thank you,

  1. Why do you have the rear fan acting as an intake instead of exhaust? That seems a bit of an odd configuration for the Thermaltake Armor A90 case.

    Check the article, it should answer your question, also check out part 2.
  3. I will remove one from the front or side and move it to the back.
  4. Oh, I forgot to mention. I'm planning to get a Corsair Hydro Series H60. In order to cool the radiator as best as possible, I would like to intake air from the outside.. since the air inside my case is quite warm from the 9800GT SLI!

    Thanks
  5. And the question remains... do I need a better 200mm fan at the top?

    Also... does any know if the Megaflow will even fit the Armor A90? I did some measurements and it seems like it's 200mm. So I'm hoping so. Just looking for confirmation.

    I bought that Megaflow 200mm and it did not fit. The thermaltake one that was removed said 172 on the label, which I'm guessing is specific to that model fan. Did I overlook a different installment procedure?
