No issue at all, can refer to the photo below
Did you notice an uplift in performance or any difference in noise going from the stock fan to the A12x15?
That looks like the perfect solution for me - my L12 Ghost S1 has some wonkyness with its coldplate, and L12S cannot coexist in the same space with the VRM heatsink/power switch/Dell plug. Plenty of space and a 120mm fan to boot.
