Cooling in the Corsair Obsidian Series 1000D

[Frederique]

Hi!

I bought the Corsair Obsidian Series 1000D which can hold 13 fans (which I wanne use to the fullest)
Description said this:
Front: 8 x 120mm fan
Rear: 2 x 120mm / 140mm fan
Top: 3 x 140mm fan

Now, a friend told me I should just put in 13 120mm fans. Can I do that (considering it says "Top 140mm")

Is there a reason I shouldn't do this? I intend on using 13x CORSAIR QL Series, iCUE QL120 RGB, 120mm RGB LED Fan.

 

Is this a good idea?

That many fans will get rather expensive. You don't need that many fans unless you're putting watercooling radiators in all available spots (For most air cooled setups you want airflow in the front -> out the back and that's it). It'll look fuckin goofy. 

 

What are you actually cooling? CPU/CPU cooler and GPU?

For the $600 you're looking to spend on fans, why not spend it on something useful for your PC?
