[SOLVED] How many case fans should I add and should they be 120 or 140mm?

[moonisahmed]

I intend to add more cooling to the case.

Below are my system specs:
CPU : Core i5-9400F upto 4.1 GHz
CPU-Cooler : Stock - Stock Cooler
Motherboard : Gigabyte - B360MDS3H (https://www.gigabyte.com/in/Motherboard/B360M-DS3H-rev-10#kf )
Graphics-Card : EVGA RTX2070
SMPS : Antec - HCG750
Case : ThermalTake H200 (https://www.thermaltake.com/h200-tg-rgb-2.html )

How many case fans should I add and what should be their size 120/140mm? The case supports 3x120/2x140 in the front and 2x120/2x140 on the top.

I'd do 2x140 front, 1x140 too and I assume the rear is 1x140?

Also, I would get a better CPU cooler such as an EVO 212 or Noctua

Agree with Solidjake, depends how important airflow is for you, personally i'd slap 3 120mm in the front and one 120mm on the top as an exhaust. Should be enough airflow

The top of those cases can fit 2 x 120mm fans or 1 x 140mm. They say 2 but if you have a MoBo with a decent heatsink and an exhaust fan it is very tight to get 2 140mm fans mounted beleive me. I have a TT L20 MT with 2 120mm Corsair Pro fans on top, 2 in the base, 3 infront, AIO on the side vent and an exhaust fan at the back and am really pleased with the airflow, my RTX 2080 idles at 32c....
