I suspect NH-L9i is going to have a tough time to handle 8700K. It is a hot CPU. Delidding will help, and possibly undervolting.You might want to go to the thread below and see what other people will say:-https://smallformfactor.net/forum/threads/8700k-noctua-nh-l9i-what-are-your-temps.6811/#post-86861NH-L9i, according to Noctua, is designed for 65W TDP CPU only. 8700K is 95W and is listed with a red 'X' as not recommended.https://noctua.at/en/nh_l9i_tdp_guidelinesTwo alternatives to consider:-a) Silverstone AR06It has four 6mm heatpipes (vs two of the NH-L9i) and is rated at 95W TDP. It runs a 92mm thin fan.b) ID Cooling IS-60This has six 6mm heatpipes and runs a 120mm thin fan. This is probably a better guy to handle an 8700K, after changing the stock fan to a more powerful Noctua fan.
