I don't use case fans anymore, they just add unnecessary noise. The 11400 is only $15-20 more expensive on amazon and gives a decent +20% single core performance over the 10400. You can probably skip all the case fans and put a $17 Thermalright Assasin X 120 on the cpu. Here's the RGB version for $2 more: https://www.amazon.com/Thermalright-AssassinX120-SE-AX120-TL-C12C-S/dp/B09S31J64R/
