If I were you, look at my temps, with that HOT 8700k I'd recommend you go all out in terms of cooling, go with the LP53 and get the NF-A9x14 PWM.
Just make sure you get temps from before and after your delid using the same conditions, since once you delid you can never go back and compare.
And i recommend the Prime25 v26.6 8K FFT's in place temp test for 10 minutes be your go-to for hottest-core temps. It's what I used in my build thread to guage pre and post delid temps and temps across different coolers and fans.
