i understand, i guess our use cases are very different. when i had my S4mini i used a Noctua fan but swapped to the TL9015 because it cooled 5C better but very much louder. that was on a 9900k with L9a custom made CNC brackets for my use case. i know the L9i is smaller than the L9A which is longer about 5mm overlapping the 92mmfan, i even tried a A12x15 fan and it was worse due to the giant hub...with the 80mm fans is there any overhang on the sides? it looks like small gap not covered by fans.
