I'm tired of trying to fix the airflow in my case (noctis 450). After upgrading to 3080 fe, this problem became even more serious. When I remove the front panel and the filter, I get -10 degrees on GPU and comfortable noise from the fans. Therefore, I decided to take a new case and priority is the GPU cooling.
I choose between these two cases, I have not found a direct comparison anywhere. I also have two good fans (140mm Silent Wings 3), which I will transfer to the new case. My build is fully air cooled and I have no HDDs.
What I like in these cases:
Meshify 2
I like how it looks more
It is possible to install two fans at the bottom (But I am not sure that it makes sense. Some people say that this helps a lot to improve the GPU temps. Others say that fans useless there, because they interfere with PSU and cables, and the air almost does not reach the GPU and much better is just to put fans on the top of PSU shroud)
It is smaller
P600S
I like that the front panel can be opened and closed.
It seems that in the stock configurations this case cools the GPU better. But I have two 140mm Silent Wings 3, and perhaps with two additional fans the Meshify 2 will outperform the P600S.
It has better build quality. At least other people say so.
I was already ready to buy the Meshify 2 case, but then I found out about p600s. Their price is almost the same in my country and both cases seem great to me. And now I cannot decide which case to buy.
