Two 40mm fans, expected temp decrease?

Hello,

 

I am considering to purchase two 40mm fan (NF-A4x20 or NF-Ax10 FLX) to place on top of my Node 202 to increase the airflow in the small motherboard chamber.

The plan was to place one fimageproxy.php?img=&key=17c10421afdc6db8an as intake where the green square is, so that air goes near the heatsink and MOSFETs, and one to blow air out of the case where the blue square is.

Theoretically, the air would flow like this (kinda?):

Do you think I am wasting my money by doing this? (each fan is $10)

The airflow setup most likely won't work. You are better off having both as exhaust.

Yeah, I was thinking that as well but didn't post again as I went to sleep. 

 

The CPU fan is going to draw air in anyway. 

 

Do you know if I can use a SATA adapter > Low Noise Adapter > Splitter > 2 fans combo?

 

I wanted to use the second LNA that came with the fans for a chassis 120mm Corsair fan I have... As I cannot set a custom fan curve in the BIOS and there is no mid way between Silent and Turbo.

It's better if you use LNA per fan.
