Cryorig A40 for overclocked CPU?

Anybody here has experience with Cryorig aio coolers? I am planning to use a Cryorig A40 for an overclocked FX, and I heard they will be giving AM4 adapters so I might be able to use it when I upgrade to Ryzen later this year.
I am curious about that airflow fan in the middle, looks like it would help cool the vrm's but wouldn't it be too noisy?
Right now my pc is relatively quiet, I can only hear the hdd.

No idea about the AIOs. But the Cryorig air coolers seem to be at the top when it comes to performance (ok... a little louder than noctua but ever so slightly cooler in the benchmarks I've seen).

I use the A80 on a Xeon. Obviously not the most stressful situation, but it works great. I don't remember it really ever being loud, but I'll have to stress my CPU later to give a better answer.

Yep, according to benchmarks I've seen they have good coolers. I don't know how to quantify the decibels though, like how loud 40db vs 41db is.

Decibels are on a goofy logarithmic scale. An increase of 10 dB will sound twice as loud as the reference loudness level. So 30 dB will sound twice as loud as 20 dB, for example.

A 1 dB difference is about as small a change human hearing can perceive.

Tried running a CPU benchmark for 10 minutes, but my CPU never got above 34°C, so the fans never actually sped up too much. Quiet though.

And if you haven't seen it yet, or anyone else for that matter, OC3D did a pretty good test on current AIOs, including the A40, two months ago.

cryorig h7 here. i7 930 running 3.8ghz never goes over 70c (though mobo claims fan errors every boot)

Very nice!
Other benchmarks I read were running the fans at 100%, which didn't make sense to me because I assume that the temps will be low enough and fans would spin much slower. Thank you for the great link too!
