Simple Case Cooling Question:

[doomsdaydave11]

Would 2 of these super cheap 80mm case fans: http://www.newegg.com/Product/Product.aspx?Item=N82E16835150007
Outperform a single high performance 120MM fan? http://www.newegg.com/Product/Product.aspx?Item=N82E16835185060

Thanks.

The 120mm produces almost double the air flow of two of the 80mm. So, no IMO.

Is this some kind of test ?
The specs.
80's- 31.73cfm x2=63.46cfm
120-110.31cfm
uhhhhhh lets see...the 120 flows more.

I already noticed that... but what conditions are they using? Why should I trust something the company that makes it says? Instead of being an ******* just answer the question.

 

[Lord Gornak]

It's not about trusting what they say, it's the physics of surface area. Larger fans push and pull more air at lower speeds that smaller fans do at higher speeds.
The 120mm Scythe you used as an example outputs 110.31cfm.
This 90mm Scythe: http://www.newegg.com/Product/Product.aspx?Item=N82E16835185048&Tpk=scythe has a max output of 55.5cfm, half of what a fan that is 30% larger pushes.

The larger fan will push more air, and likely be quieter than having 2 smaller fans. So the 120mm is a win-win situation. Not to mention it could possibly draw less power too (not like that's a very sizeable draw anyhow).
