Corsair Obsidian 800D Question

[exposed]

I have the corsair 800D and i just bought 3 Silenx Red led fans 73 CFM and 2000RPM and instead of making them suck air out of the top i faced them all down blowing cool air into the case instead of sucking hot air out ? is that a good decision ?

Heat naturally rises. You are forcing air against this natural flow. This is not a good idea.

To get the best cooling you want intakes in the front and side of the case, and exhausts in the top and rear of the case.

Edit: This is true for any case.

oh dang , could it hurt anything?

No, it won't hurt anything. However, your temps will likely be higher than if the fans were set up correctly.
