Posted September 6, 2021 So my pc currently is housed in a Lian Li O11 dynamic XL. My cooling configuration consists of 2 140mm fans on the bottom as intakes, 3 120mm fans on the rad which are also intakes and 3 120mm fans on the top as exhaust. I have been thinking of swapping out the 2 140mm fans on the bottom and putting 3 120mm fans there instead. The reason would be to make it look more filled out. I am also probably gonna put another 120mm fan on the rear as a exhaust. Would the 2 140mm fans be better then 3 120mm or vice versa?

Posted September 6, 2021 A 140mm fan is approximately equivalent in air flow to 1.5 120mm fans of similar build. There will be little if any difference. ¯\_(ツ)_/¯ Desktop: Intel Core i7-11700K | Noctua NH-D15S chromax.black | ASUS ROG Strix Z590-E Gaming WiFi | 32 GB G.SKILL TridentZ 3200 MHz | ASUS TUF Gaming RTX 3080 | 1TB Samsung 980 Pro M.2 PCIe 4.0 SSD | 2TB WD Blue M.2 SATA SSD | Seasonic Focus GX-850 | Fractal Design Meshify C | Windows 10 Pro Laptop: HP Omen 15 | AMD Ryzen 7 5800H | 16 GB 3200 MHz | Nvidia RTX 3060 | 1 TB WD Black PCIe 3.0 SSD | 512 GB Micron PCIe 3.0 SSD | Windows 11 Link to comment Share on other sites More sharing options...

Posted September 7, 2021 As others have mentioned, it will be mostly cosmetic, no real change in cooling performance. Link to comment Share on other sites More sharing options... Link to post Share on other sites More sharing options...
