Can you tell me how to adjust the turntables?
I have an NZXT H510 case without a control unit, inside there are 2 fans of the same company with 3 pin connectors. Connected to the motherboard. Also installed SVO with a radiator with two more turntables. For them, there was also a connector in the kit to which both fans were connected, and he, again, to the motherboard.

The temperature in everyday tasks is about 30 degrees now, but the turntables are spinning at about 900-1000 rpm., Sometimes it comes up to 1300. You can hear them loud enough. Moreover, the body is on the table.

I set the BIOS to quiet mode, but it doesn't look like quiet. Tried to set everything manually, same result. There is a PWM mode. But for him, it seems like you still need 4 pins on the connector. I tried to download SpeedFan but it doesn't show anything other than the GPU spinner.

Tell me what can be done, and is it possible to lower the speed of the turntables in my case at all? And it is desirable that everything be in automatic mode, so that under load the speed increases all the same

If the connection is three-pin, then it is impossible without a control module. You can put a resistor in front of the cooler, thus reducing the voltage and speed, but you will not be able to dynamically change the speed in this way.

Switch the speed control from PWM to DC for 3 pin turntables.

This is usually done by the motherboard, depending on temperatures, but there should be 4 pin connectors.

3 pin fans are not adjustable. Just the cooler with the 4th pin, the 4th pin is the control one.

What motherboard? What cooler settings are there in manual DC mode?
In modern boards, you can draw a graph of the dependence of speed on temperature, in older ones, the min / max temperature and min / max cooler speed are indicated, this combination sets the desired mode.
speedfan is too old, I recommend using https://github.com/Rem0o/FanControl.Releases

Think over the airflow, "debit and credit", the ventilation of critical places, the absence of stagnant zones, the installation of the PC itself, so that hot air does not return to the case.
In a powerful modern PC (well, let's say a home gaming PC), even with a 1st fan on the back wall, there may be enough purge so that there is no overheating. True, the choice of spare parts should have begun AFTER thinking about cooling, and not vice versa.
In my case, there is an RTX with a turbine, plus one 120 mm for blowing (not counting the power supply), and one inside for blowing the HDD. Everything is quiet and beautiful.
