It is unwise getting higher rpm fans and expect logical modo control, when this controller it is designed for lower rpm fans.
Gelid Silent 14 is 1000 rpm.
14 PWM is 750-1200 rpm.
I am not aware of Gelid selling these in ball bearins variant even if they did exist over 10 years ago.
The Silent 14 used to be an OK cheapo case fan for no obstructions use if you could get it and get it cheap.
For some time though I think Arctic replaced most cheap fan options with their F series and later with P series especially P series with PWM.
I still have those Gelids and they are no match to the Arctic P PWM.

That's just it.
Well, sometimes it is an issue. For example, after midnight when you need to reboot several times, but your wife is sleeping near. These two 140 mm fans at 1500 rpm sound really like a drill.
That's not how motors are supposed to be started. And the starting voltage when increasing from zero smoothly is higher than simply kicking a voltage right away. Such as going smoothly from 0 the starting voltage to get any spinning could be 7 V even though the fan my start spinning at 5 V if you don't do it smoothly from 0 but abruptly. If the fan isn't spinning then the power has to dissipate somewhere as heat.
It's a technical thing to start motors at a higher impulse.
If it bother someone on PWM fans... well run them at lower voltage or get smarter fan control. For me it really spins the fans from PC powered off on max speed for a few seconds only enough for the fans to start spinning well and then immediately quiet down as POST shows up. Aka during initial start up of the machine when there likely isn't any fan control signal the fan controller ICs spin the fans at max, when they are finally told the desired speed/PWM they slow down.
In case of failure, it's better to have fans spinning at max than not at all.
Again technical details even safety.

Only way to make it run quiet is to set it so fans don't spin at all until temps reach 55c. This way case fans rarely run.
Luckily CPU fan headers will idle down to lower speeds and a mate is sending me a Phanteks PWM controlled variable voltage fan hub. I'll plug case fans into hub and hub to 2nd CPU fan header. Hopefully this will solve problem.
I've often wondered if the engineers designing things have any idea how things work in real world. All of them should have to spend 1 month a year in the field working on the things they design. That would be a real eye opener for many of them.
That's some weird controller, bet it's one of those that tries to detect fan speeds and give you control of that instead of doing it good old dumb way, here is the PWM % you can adjust, do what ever you want. Some of these "smarter" controls try to offer RPM selection or RPM range % instead of true PWM %.
It's a typical management failure, here make us this, so it gets made and no one much cares who and why will use it, what the true needs are.

Last free version of aquasuite was 2016 release, and it can still be DL'ed free from aquacomputer website (see below).
New aquacomputer controllers come with latest version and 1 year subscription of free updates (might be good idea to update before 1 year subscription expires).
After subscription expires if you want to update to newer version you have to buy a new subscription (cost about $10/ year)
You can download last free version of aquasuite software by clicking on link below:

Is that a pure hardware solution or does it rely on software control. As in can it accept PWM signal or does it need software running on top of an OS to be able to read out CPU/GPU/... temperature. Because if it needs software running then well may as well use a free Speedfan etc. to control fans based on anything on any port. Temperature probe fan control is very old, can work in some cases but attaching the probes is usually the same old pain to do.
