Should I go with 2 140mm fans or 3 120mm?

3x 120s will likely push more air at the same noise level, or the same air at a lower noise level vs 2x 140s. They will also likely have a higher max airflow. I prefer 140mm fans in general, but in this case I'd go with 120s.

The Fractal Design Meshify C's front can accept either two 140mm fans or three 120mm fans. Assuming I want things to be as cool as possible in my case should I go with the two or three? I assume 140mm fans are more powerful, but the fact that you get 3 of the 120s makes me unsure of which to go with. Any thoughts on which would be better for a cooler PC?

 

Edit: Okay so turns out I should've googled this first because I'm definitely going 140mm. You have to take out the PSU shroud to go with three 120mms. My bad wish we could delete posts lol

I think most likely I"ll go with 140mms just because I like how much neater the shroud will make the case look, but I will factor this into my decision! Won't be building for awhile as I wait for Zen 3

A pair of 140s will do nicely so don't sweat it.

Before I switched motherboards I was running a Meshify C. Great case. I tried 2x140s and 3x120s and preferred the 120s.
