Windows 10: Case fans speed randomly goes up and goes down

I got a tower case and 4 case fans installed. One in the front to suck in air, one one the floor to push air up, one large one on the side to pull in air and one on the back to push out hot air. I recently did a clean install and had a few freezing problems that was fixed by doing the solutions and bios update but I realized soon after that my case fans speed speeds up randomly and goes back to normal a right after. It's not causing any problems for me other than annoying me, but I'm worried it will damage the fans if this keeps up.I tried setting the fan speed in BIOS but not sure what to do.

You might not want to gloss over the problem that way. They shouldn't be doing something like that in the first place really and there's another issue that your fix is simply masking.

The fan speed is supposed to ramp up. I don't know if its a driver, physical issue with the GPU, issue with that GPU's firmware, or a heat or airflow issue with your computer.

But, something isn't right. Whatever is happening, there's going to still be something going on in some code, in the case, with the GPU, or whatever despite forcing the speeds by another means.

The only thing that tells you is that the speeds are drastically changing and its involving the GPU fan speed. You could watch the GPU temperature and see if it spikes when the fan speed increases, talk to the manufacturer, etc.

 

Windows 10 Randomly goes to hibernation

Hello,

I am writing about my Lenovo W530 with Windows 10 64 bit. All of my drivers are up to date, it has optimus Nvidia Quadro 2000m + Intel HD 4000 GPU and it is a triple-boot with linux systems and the following only happens on the Windows 10 side.

It only started doing this since Yesterday with no significant update.

While connected to charger and hooked up to my TV through mini-Diplay port, the laptop once a while randomly decides to go for hibernation. It is sitting on a chill matt and no thermal issues, everything hardware wise is perfect.

I checked the reliability log, nothing suspicious, the sleep study shows that the laptop randomly goes into hibernate mode. Power settings basically tells the computer to never sleep or hibernate in any case.

The computer goes into hibernate even while in use, I was quite annoyed when it did that during a Zoom meeting, my Zoom guest told me that he got a warning that my computer is about to disconnect due to low power.

My battery is fine, and it is fully charged!

Any suggestions? For now I swapped out the battery to see if that helps, I will try the CMOS battery next but I don't think it's a hardware issue since everything checks out fine on the linux side.
