Hi Dude
Thank you for this post.. is helping me so much in deciding what to do..
i am planning to switch to the same MB+9900 k from z370 strix + delidded 8700 k, for the moment i have h115i pro on top and 2 140 on front, everything is good except for the gpu , a strix 1080, going to change it these days for an evga 2080 ftw3.. something that help me some is using 4 record player feet to increase the height.. and of course, removing the front dust filter...
