Like the title what is better a normal noctua nh-l9i wit bigger 92x92x25 fan or LP53 that is better but with a Noctua 92x92x14 Fan.???? All inside Antec ISK-110. Many thanks.
I tested both and I believe that the LP53 will cool better because the L9i is pretty weak and is for like non-k varients eg the i5-8400.
The (copper) LP53 can cool my delidded 8700K no OC - with the L9i fan (3mm to spare) - idling 39c and I maxing at 62c with CSGO via iGPU.
While the Cryorig C7 (fan right on the case side panel) struggled to cool until I delidded it - within mid 80c both in a Skyreach 4 Mini.
It really depends on what CPU you were going to use it with.
What did you end up going with?
