Question Front RGB case fans constant red after restart

Hello everyone.

I was uninstalling and re-installing a software that required restart so I restarted PC 3 times in a 5 minutes maybe and while the last restart was doing it’s thing, it was slower than the first 2 restarts. It kind of stalled for a second or two and then continued. First 2 times restart was “lightning” fast as it should be with the NVMe m2 ssd I guess. After the last restart, 3 rgb fans on the front side of the case became red, constant red. MBO is Gigabyte B550 GAMING X V2 (AM4) and it doesn’t have RGB on it, or at least, I am not aware of. Generally speaking I keep RGB fans turned off. Other than that I did not notice anything strange or misbehaving of the windows loading or in general use while fans are red 2 days later. I’ve started Gigabyte control center software and because the profile is set to RGB off, the software turned off red fans but after turning the PC off and on they are red again. I’ve used Hwinfo software and one line of data is red and was red already before, like months ago. PC is not underclocked or overclocked. I’ve taken several screenshots of the “red data” and to me it looks serious (percentages is significantly different) but I am not an expert so I am asking you.

Is „red data” important? Do I need to check something specific that could cause fans to be red? How do I turn them off? It doesn't bother me that they are red as long as there are no problems in the background I am not aware of. Thanks in advance for your help.

That's not the BIOS version for your motherboard. Use CPU-Z to tell you on the Mainboard's tab what BIOS version you're currently on.

Your board comes in different revisions, which one do you have? You can identify the PCB revision number on the bottom left hand corner of your motherboard, near where the front panel audio header is located.

To add, your board does have RGB and ARGB headers, which leads me to ask what the make and model of your case is(if the fans came bundled with the case)? If the fans were purchased standalone, then simply stating the make and models of the fans will help us two fold.

Speaking of which, what are you using to cool your processor? You forgot to mention the make, model and age of your PSU.

Are there causes of concern? Not really, as long as your CPU temps are within reason during load.

For further reading, lately there was another person in TH forums who asked the same thing about Power Reporting Deviation and where i answered their concerns,

As far as your fan LEDs go, what exactly are you looking to solve?
The red color they display, so that no red color ever shined (LEDs turned off)?
Or are you looking for ways to restore the (A)RGB function, where the fans shift through different colors?

Since Power Reporting Deviation and your fans shining red color are two completely different issues and not connected to each other in any way, shape or form.

Thanks for the quick response. Here is an update. Mother board is rev 1.4. PC case is Thermaltake Midi Tower S200 TG ARGB, glass window, Black, CA-1X2-00M1WN-00, 3 RGB fans are in the front side and one on the back side. CPU Cooler is Xilence M705D. PC is still under 2 year warranty and I can't see any info about the PSU since it is closed in but it should be Corsair 750W RM750X Black, 2021, 80 PLUS Gold, CP-9020199-EU. Is there a way to find out info about PSU type, manufacturer via software just like we can see info about MBO or GPU? I've tried but couldn't find the solution.

As I wrote in the initial post, after the restart which wasn’t typical front case RGB’s started to shine constant red color. If I turn it off via Gigabyte center software it shines constant red again after next reboot. This kind of confused me in a way that something maybe wrong. Red color usually means a warning. Also, since I’ve noticed that deviation about voltage percentage so I thought that might be connected. I am not an expert in details about PC’s and that’s why I sent a post here. My concern is that there is some kind of problem that causes fans to be red every time system is booted. This has never happened before.

I’ve tried to control other RGB lights on the MBO via Gigabyte control center but nothing happened. The only lights I can change, turn on/off are 3 front ones on a case. So it seems those who were connecting PC parts didn’t connect MBO RGB since I can’t do anything with it or MBO RGB and from fans can’r work at the same time?

If red fans are result of the temporary glitch which has no other negative impact on PC performance I am ok with them being on. Still, I would like to have an option to turn them off.

Thank you very much for the help.
 
PC is still under 2 year warranty
So, it is a prebuilt? Rather than DIY build (where you assemble the components by yourself)?

If it is prebuilt, you should contact the store from where you bought the whole thing, since they are obligated to provide you customer support for your PC and any issues/questions you have with your build. But if build is DIY, then you, yourself, are customer support.

Is there a way to find out info about PSU type, manufacturer via software just like we can see info about MBO or GPU?
No. Not at least for your analog PSU.

There are digital PSUs out there, that do have dedicated software to see what they are up to and to control them to an extent. But such PSUs are rare and expensive. Once such unit is Corsair AX1600i (1600W). Another one is NZXT C1500 (1500W).
Then, there is "semi-digital" PSUs, like Asus ROG Thor 850P (850W), where you can control it's ARGB and OLED panel via software, but otherwise have no say about PSU's working.

Though, huge amount of PSUs out there are analog PSUs and other than actually looking the label on the PSU, there is no other way to know the PSU's make and model (or part number).

If I turn it off via Gigabyte center software
Well, if your case has the stock Thermaltake ARGB fans,
case specs: https://www.thermaltake.com/s200-tg-argb-mid-tower-chassis.html

And you've seen fans changing color, then your fans need to be connected to your MoBo 3-pin +5V ARGB header. Else-ways, none of the LEDs would ever light up. And as you said, you can change the LED color (turn them off) from the software. So, there is software control still.

As of why fans shine in red, difficult to tell, but my guess is that something has gone wrong with the fans themselves, for them to revert and get stuck with red color.
To permanently shut off fan LEDs, just unplug the 3-pin +5V ARGB cable from your MoBo.

The cable looks like so:

Male ends go to the fans while the female end goes to the MoBo.

The LEDs for the fan are purely for eyecandy and doesn't impact the fans cooling in any way, when LEDs are disconnected.

Still, I would like to have an option to turn them off.
Well, you can, from Gigabyte software, right?
