McGuinness Posted May 30, 2021 Share Posted May 30, 2021 I currently have my h150i 360mm on the front as it's the only place for it. I have one fan in the back of the case and none on the top. My video card runs pretty hot at stock settings 76-79 under load and I'm wondering what a good solution to getting that hot air out of the bottom of the case could be. The top of the 4000D Airflow has space for 3 fans. What would the optimal thermal solution? 3 fans all exhausting on the top, plus the exhaust fan in the back? Any suggestions on which fans to use (size / model)? I'd actually prefer non-RGB on the top. Thanks! Link to comment Share on other sites More sharing options...

c-attack Posted June 7, 2021 Share Posted June 7, 2021 Running any fans on top is going to be more impactful than none at all. Fan type or blade design isn’t going to matter much. The bulk of the gpu waste heat should be on top of the card as it radiates from the backplate and sides. The fans under the gpu should displace the air below.

Corsair Employee Corsair Johan Posted June 7, 2021 Corsair Employee Share Posted June 7, 2021 Me personally I would have the front fans for the AIO as intake and then have fans in the top and back as exhaust. If you dont want RGB I would recommend the ML fans for the top. Link to comment Share on other sites More sharing options...
McGuinness Posted June 10, 2021 Author Share Posted June 10, 2021 Thank you for the reply. Do you know how many fans and what size I could fit on the top of the 4000d airflow edition if I went with the ML? Link to comment Share on other sites More sharing options...
LeDoyen Posted June 10, 2021 Share Posted June 10, 2021 it's all in the case specs :) https://www.corsair.com/corsairmedia/sys_master/productcontent/WW_4000D_4000D_Airflow_QSG_AB.pdf 2x 120mm or 2X 140mm fans on the top, 1x120 on the back Link to comment Share on other sites More sharing options...
