The new 1900 rpm pwm SP120 used on the 2018 cooler hit 31db each. The older style used 2000rpm SP120L analog fans that'd hit 38db, each. Pretty much double what a Noctua NF-F12 will hit.
The original hyper212/plus used a 2000rpm analog fan that'd hit 32db.
The updated EVO uses a 2000rpm pwm fan that'll hit 36db.

The difference between the EVO fan and either of the H75 fans is the performance curve. The EVO fan has stronger cfm/sp at lower rpm, after @ 70% duty cycle there's little gains. The SP120 has a more relaxed performance curve, the higher the rpm, the stronger it gets.

Since you'll almost never be (or shouldn't be) running the cpu fans at 100% duty cycle, you'll get better performance from the EVO fan at moderate speed levels...

Corsair's older style AIO fans are miserable. They work well, for sure, but to get good performance out of them requires high rpm. And a set of ear muffs as they are also very loud. Those fans on the H75 are the same fans as used on the older H100i which will hit 45-50db (think refrigerator compressor).

Stick with just the stock hyper212 fan, it's quite a bit quieter and has better performance at lower rpm.

Are you talking about the old H75 or the 2018 version?

Also figure it like this. Corsair is all about performance per $. The fans cost Corsair roughly the same amount. If the H75 SP120/L got better performance on that heatsink than the BladeMaster did, that'd be a bonus freebie to Corsair, same cost (probably cheaper considering the bulk rates) for better performance = win-win

Would a ML120 do anything?

Yes and no. The ML as such is a far superior fan to the older SP/BladeMaster series, and almost dead silent at high speeds. So you'll get equitable performance at similar rpm, but you can adjust your fan curve to hit higher rpm a lot sooner, because they are that quiet. Higher rpm = better cfm/sp = better possible performance. But there is a marked difference between the standard ML series and the ML RGB. Once you add RGB to any fan, you'll lose out a little on performance as the motor is slightly smaller due to the requirements of the RGB controller circuitry inside the motor housing. Only so much alloted space.

And you could buy a new cooler, one that outperforms the hyper212 evo for what you'd pay for an ML series fan. So unless the fan were basically free, it's seriously not worth it.

I wasn’t going to put a ML fan on there anyway I was just curious.

Yeah, the ML's are really nice. They came on the original Pro versions of the Corsair H100i, H150i etc, but Corsair has since dropped those fans in response to overwhelming numbers of RGB fanatics buying the competition because of stock RGB fans. Pity, performance went into the toilet with that decision. Nice to look at, can really compliment a build, but don't perform near as well as their non-rgb version.
