One last question, If I were to buy Corsair ML140 and replace stock fans, would it really make a difference, or improvements would be minimal (3-4C)?

ML140 non RGB should help a decent margin (expect at least 5C drop), RGB variant wont help as they are limited to 1200RPM.

 

But with non RGB radiator fans, I'd rather use other models like the Noctua NF-A14 or Arctic P14. Corsiar use MLs on high end AIOs not because they are that good on heatsinks or radiators, but they dont have anything better. The SP are rather loud, AF lack pressure, HD and LL dont perform well in general, focusing on lighting above all else.

Hello everyone. 
I've build my first rig about one month ago and have been trying to find optimal overclocking settings for 9900k (using Corsair H115i PRO for cooling) since then. It seems my luck isn't as much good as I thought it'd be, and was able to reach stable 4.9GHz at 1.29V with LLC Turbo, 5GHz is possible but temps get unreasonable. However, I'm concerned about temperatures running such benchmarks as Cinebench R15, R20, Intel XTU stress test (max 86C), Aida64 (it reaches 94C after 15 minutes of running). I've resitted the AIO several times and even applied aftermarket thermal paste, which helped a little, but isn't enough. I checked the airflow inside the case, too.
Reviews say that others could reach lower temps at higher voltages using the same CPU cooler. What could be the reason of this? Also, is it safe to have those temperatures?

Yes, the settings are at "Extreme" in ICUE, it helps to lower temps only by 2-3C.

The 9900K is a pretty hot CPU, especially when overclocked

I cant find data on the H115i Pro, but only those for H115i Platinum and other similar 280mm rad coolers. Thing is the H118i Pro has the lowest fan RPM (1200RPM), comparing to the Platinum's 2000RPM and EVGA's CLC 280 with 2800RPM fans. Slower fans = worse performance, that seems reasonable.

The 9900K is a very hot CPU, you would be better with a top end Noctua air cooler or a biger AIO.

Well, it seems reasonable, but I can't understand how other users with the same cooler could achieve lower temps at higher voltages. That seems unreasonable.
Anyway, are these temps safe or it may cause problems at some future time?

1.3v is quite high usually you could get like 5.2GHz with that voltage. Try drop your volts for 1.2v you can get 4.9GHz with that.

I've already done this, but with no luck and 1.29V is the only stable voltage. 5.0GHz requires 1.330V but I haven't fully tested it since temps are so high.  As I said, silicon lottery wasn't at my side unfortunately. Btw, can high temps be due to cpu itself (bad silicon lottery?

Just don't stress test it, near 90C is high but at below 1.3V I doubt you'll see any degradation anytime soon.

5.2GHz 1.3V? That's for the top bin of 9900K if not the KS. You should not expect that out from every 9900k.
