the case fan makes like Turbine noise

[gaz2210]

Hello

sometimes when i turn my computer on, the case fan makes the noise like if it was an turbine, my friend told me that it is ok as there is no Software to control the fan and when OS is starting in my occasion Windows 10, it takes control of it and change the fan speed to the normal after a while, maybe because the heat after night play is still in the case and other components as it just have few hours of cooldown, playing games that really kills the GPU and CPU, but i let it go for i think 2Minutes but then i realised that nothing was changing, as if it wasnt the OS fault, i checked the cabling if everything is plagged and nothing is touching to Hardware, but everything which is necessary to make PC run is plagged and nothing is touching, i checked that it is the Case Fan i spin it by hand when PC is turned off and saw that sometimes is it moving Forward Backward when spinning, is it the natural thing that the fan is doing this, or thing that is attached to it has loss and have to be put in place? also i changed the Thermal Glue ( or whatever it is called, i just like calling this Thermal Glue as it is easy to remember, and keep CPU and temperature in place like glue ) and i clean the PC out of Dust and other things with Compressed Air, ( i think in American Eng this is spelled differently but i live in UK so i use UK eng so please try use UK eng as i can get confused ),

Thanks for help,suggestions and explanation, and dont be shy if i made mistakes, we all make mistakes and learn from them, i will not judge you from mistakes, more likely i made some mistake with the OS controlling fan.

Try adjusting fan speed in the BIOS instead of in OS.

i rrestared the settings on my UEFI but still sometimes when turning the PC On i can hear it

That's normal, it does take few seconds to stabilize speed.

That's normal, it does take few seconds to stabilize speed.

i gave it 2minutes after the Logon screen, but still there was that Turbine noise, few minutes ago i gave 5minutes for it and it didnt go afterall,

This is true for Asrock b350 boards on power up the fans will startup high and after a few seconds it will normalized according to the fan setting in your bios. It seems your fan control settings in the bios is set to high speed or performance mode. you can adjust this in the bios settings.

Are your fans connected to your mobo fan headers ? or to your PSU ?

The explanation here may be one of three things, OP, so check these and you can figure it out better.

1. This MAY be the first signs of the fan wearing out. The symptoms of this go like this. When the system is cooled down from not operating for a while and you first turn it on, the fan is very noisy, and this continues for one to several minutes. But eventually it gets quiet and stays that way. In more severe cases where the fan is badly worn, it may never get quiet (see below). If that is the symptom pattern here's the explanation. As a fan is used its bearings slowly wear, making the tiny gap between shaft and bearing hole bigger. When the system is cold and started up, the shaft is too small and so it rattles around in the bearing, making noise and causing the fan to run slowly. But within a few minutes the system heats up and the shaft expands, making the gap smaller and the rattling (and noise) stop. Over more time, the symptom will become worse until the fan fails. So this is a clue that you will need to replace the fan sometime soon. In severe cases when the bearings already are badly worn, the noise may never stop. To test for this, shut down your system and unplug from power. Open the case. With your finger, reach in and try to spin the fan. If it spins freely and coasts to a stop gently, then it is OK. But if the fan is very stiff, or if it stops very quickly when you stop pushing it, then it is badly worn.

2. This second situation will happen can matter whether the system is cold or warm or hot. With power off, open your case so that you can see the fans easily. Now start the system and watch them all carefully to see their speeds. The NORMAL way is this: when first turned on, ALL fans will start up at full speed to be sure they do get started. In a few seconds (3 to 10, typically) each will slow down when the system finishes its initial POST routines and starts to exercise actual control of fan speeds.. After that the fans all will change their speeds up and down according to the workload (and heat generation). If that is what you are seeing, there is nothing wrong at all, so stop worrying.

3. If you observe, instead, that some or all of your fans start up at full speed and never slow down, then the fans are NOT being controlled. There are three possible reasons for this, and each has a different solution.
(a) the fans that do not slow down are connected directly to the PSU and get full 12 VDC power all the time, with no mechanism for control. To change that, you need to change how the fans are powered.
(b) The fans that do not slow down are connected to mobo fan headers that are configured NOT to control them. One common version of this is if your fans are of the 3-pin design but are connected to a fan header that is using the newer PWM Mode to control them. 3-pin fans have three wires (Black, Red and Yellow) from the motors that end in a female connector with 3 small holes in a row. 4-pin fans have four wires, and the end connector has 4 holes. If this is the case, you may be able to go into BIOS Setup and find the place where each of those mobo fan headers is configured. If it is available, change the setting so that the header uses Voltage Control Mode (aka DC Mode) instead of PWM Mode. After making your changes, be sure to use the SAVE and EXIT commands to save the new settings and reboot.
(c) The troubled 3-pin fans are connected to mobo headers that CANNOT be set to Voltage Control Mode, so there is no way for you to change this behaviour in BIOS Setup. In this case there are a few other options possible.

OP, check these points, Post back here with what you find. If you need more help, post two pieces of info:
A. Exact maker name and model number of your mobo. Where on the mobo are the fans plugged in?
B. What is the maker and model number of each of your fans? How many wires (and pins) does each have?
