ASUS m5a78l-m lx3, FX-6300 CPU, GTX 970, SPC Zephyr 120mm Fan: Addressing High RPM and Vibrations

Hey!
I have an ASUS m5a78l-m lx3 motherboard with an FX-6300 BOX processor.
My problem is that the computer is very loud and transmits vibrations to the floor even at rest.

I downloaded the HWiNFO program and noticed that at rest the temperatures are ok, max 40 degrees on the CPU and 47 on the GTX 970, except that the graphics fan accelerates to more than the minimum at 60 degrees so it is definitely not the cause of the noise.
The RPM of the CPU and GPU do not exceed 1500RPM at rest, but my eye was caught by the RPM value of the chassis fan (Chassis). At rest, a minimum of 3700RPM, almost 7000RPM under load.
The computer vibrates really hard, you can hear it in the room below it on the ground floor.

Is such rotation possible at all on the SPC Zephyr 120mm fan? According to the manufacturer, it has a maximum of 1100 RPM. Is it a read error or what? I have one more fan in the front, connected via MOLEX, it's a NoName, but I don't have any readings from it.

My housing is SPC Regnum RG1, the airflow is weak in it, that's why the fan is so tired?

Unplug the case fans from the power supply and check. Why is the case fan controlled from the motherboard? Both should be molex. I have five 3-air and 2 exhaust fans in the housing and neither is attached to the board.

The fan was on 3pin so I had to connect it to the board, I didn't have a molex adapter. I'm about to check how the computer works without a fan enough

EDIT: I unplugged the fan from the housing, I did not notice the difference in volume, still the same, but the temperature is a failure, 65 degrees on the processor at rest. I fired HWiNFO, the CPU fan disappeared and the Chassis stayed and still has 6000 RPM. I am 100% sure that I have connected everything well on the board, you cannot confuse the 4pin connector with the 3pin connector and the white CPU tip with the black valve. It turns out that the Chassis is confused with the CPU in HWiNFO and this BOX is so loud.
Well, thanks for your help.

Why can't it be connected to the board? The fan connected to MOLEX works at 100% and there is no adjustment option.

I have assembled several dozen computers. None of them had case fans plugged into the board. The CPU fan and the Northbridge fan are plugged into the board, if one can be installed, because as a rule the boards are designed in such a way that the bridge cooling is connected with the CPU cooling with heat pipe and it cools the CPU fan.
If you can, please give me an example where the housing fan is plugged into the board.

So maybe you can tell me why motherboards sometimes have 4-5 connectors for 3 and 4 vertical fans, depending on what you need. Currently, molexes are hardly used anymore and I have not seen a fan for SATA yet Here you shouldn't brag about what you did wrong

I am so sorry, my colleague.
I didn't mention the fan on the SATA.
What friend has a desktop computer case at the moment?

Gladius X60, it has 5 3pin fans connected to the controller. I do not use connectors on the motherboard because I prefer to have fan regulation at hand. But that's not the topic for me.

Neither do I. I have three blowing fans and two exhaust fans attached to the Molexs. The entire casing is kept at a low overpressure so that no dust can penetrate. There are electrostatic filters on the blow-in filters to trap dust.
Are your case fans powered from the motherboard?

No, I wrote that they are connected to the controller that is in the housing.

So they are not connected to the motherboard? It would be correct because I have never connected the case fans to the motherboard only to the power supply. And what kind of board has power outputs for case fans? And they are not powered from the power supply, but from the board.

They are not because of what I wrote. Everything that is in the computer is powered from the power supply, connecting the fans to the board or the controller has the advantage that it is possible to adjust them. Connected directly to the power supply, they work non-stop at 100%. End of OT.

good luck mate in cooling.
Best regards.

These fans are selected with speed and efficiency so that they are supposed to run at 100%. Not with regulation. Adjusting their speed will disrupt the airflow in the housing.

If we have all the fans of the case connected to molex, what if we buy a case with one or two fans with 3pin connectors? We are not supposed to start the computer until we get a 3pin to molex adapter? When the temperatures increase 3pin, it will not raise the revolutions because there is no OWN, and the molex will be at 100%, the temperatures will be the same, the noise too. 3pin can only be controlled by changing the voltage, i.e. the controller. It will raise the speed, depending on the temperature, only 4pin PWN, just like CPU FAN.

So there is no difference if I have a 3pin on the board or a valve on the Molex.

HWiNFO confuses the sensor readings. The CPU valve had 6000 RPM and the case was 1500RPM, which is as much as the maximum. I think I am going to replace the processor cooling with some better ones

And where does it say that there is no speed control on the 3-pin connector? Not all discs allow it, but that doesn't mean you can't.

Of course, it is possible only with the PWM signal, but with the V control (but not every board supports this solution).

As for PWN: http://www.pwn.pl/ (I know a typo).
