Best cooling solution for i9-9900K

Hello, I am looking for a new cooler as my cooler that I have right now is not doing the job. My cpu is OC @ 5GHZ @ 1.3 volts and temps when benchmarking are 95+ degrees. At idle it's anywhere from 55-60 degrees. The cooler that I have right now is the H115i pro platinum from Corsair. Will a 360mm AIO benefit this situation? I don't feel comfortable leaving it as is because the pc is on 24/7. I was hoping that someone could help me with this issue.
Thanks

What CPU do you have? Those temperatures seem rather high for a H115i Pro, though. For example, I have a i7-9700K that runs at stock with a H150i Pro and it does hit those kinds of temperature, even with a small FFT Prime95 torture test. At idle, it averages around 37 C. I'd personally strip everything down, reapply some decent thermal paste, clear dust out of the fans and radiators, before considering replacing the cooler.

Hello
So I have the i9-9900k and I have tried new thermal paste even swapped out for some Noctua fans no difference what so ever

Well Hardware Unboxed used the same cooler on a 9900K:


So while 95 degrees C is still pretty hot, it would seem for that cooler, it's perhaps not a huge surprise. Looks like a bigger AIO will be the best way forward, although there will be better people on the forums to advise you. What I can say is don't get the H150i: it's performance doesn't justify the price (although I got it mostly for noise reasons).

I was looking at the Arctic Cooling Liquid Freezer II it is a 360 mm aio is this cooler any better it comes with a 6-year warranty and claims to be a pretty quiet aio...

Quiet isn't good for cooling though - this is the problem with the H150i; it's very quiet under normal settings, but the cooling performance is nothing special for a 360mm radiator. It's only when you have the fans at full rpm, do you get a decent amount of heat being transferred from the CPU, but at a serious cost to noise levels.
