Voltage, load type, program, and some LLC settings will impact your end CPU temperature. Certainly there is variation among samples as well. However, if you are trying to assess if the cooler is sufficient, you need to look at your coolant temperature delta. Each degree of coolant temp rise is in effect a +1C penalty to CPU temp. I would expect a normal average of around +6C for the 9900K with the H150. +3C is about as low as you can go for any cooler and hardware without resorting to external cooling tricks, so that gives you an idea of the small gains on offer. Most people will get more mileage out of a delid, but that is a debatable option for the 9900K. It sounds like you have plenty of headroom anyway, unless your intent is to hunt Mersenne Primes all day long.
