What about temperature during intensive gaming sessions? GPU is not cooking SSD?..
It might be a bit different in the 550, but in the 580 I've got top and bottom fans all set to exhaust. My 1080ti gaming X actually runs cooler than it did in my Meshify-C and has next to no impact on the SSD temps. Playing Total Warhammer 2 for an extended period and the 660p only rose by 5 C.
