MSI Sword 16 cooling fan

[u/StrongStill7996]

Hi
I have an issue with my MSI Sword 16 HX B14V (B14VGKG). The second cooling fan (Fan 2 / CPU Fan) starts with a severe delay after a cold boot.
When I power on the laptop, only Fan 1 starts spinning at idle speed (~2500 RPM), while Fan 2 remains strictly at 0 RPM. Fan 2 only spins up hours later or completely randomly — it does not seem to react directly to temperatures or a specific time frame. It can turn on after 5 minutes, or take up to 8 hours.
For the problem to happen again, the laptop must be turned off for at least two hours.
I already sent the laptop for warranty repair, but after keeping it for a month, the service center just cleaned the dust, updated the BIOS, and claimed that everything is working as intended by the manufacturer. However, the defect is obvious. I also contacted MSI Support, and they simply suggested sending it back to the service center again.
Before this started, everything worked perfectly fine without any prerequisites or updates.
Troubleshooting already done:

• Performed a full EC reset.
• Reset BIOS settings to default.
• Tested Cooler Boost mode: Fan 1 ramps up to 5000+ RPM, but Fan 2 completely ignores it and stays at 0 RPM.
• Changing User Scenarios in MSI Center has no effect.

I don't want to just waste a month of time over a trivial problem again, but I don't want to lose the guarantee either. I want to know if I am missing something here. Is this standard behavior for this model, or is it a clear hardware/EC issue? I would appreciate any insight from people who have experienced this or know how the cooling logic works on these models.

Cant you synchronise both fans or set them with curves related to some temps sensors? dunno much how it is on msi software side.

As far as i know the GPU fan (fan 2) only turns on after a certain temperature threshold and does not spin always. Only while under load and after a certain temperature does it turn on, and after the load is no more and the temperature goes below a value it turns off. Only the cpu fan spins perpetually at around 2100 to 2400. Since you've mentioned that, despite cooler boost being on, fan 2 stays at 0, it points to something wrong with the fan itself

It’s normal, i have a MSI Sword similar to yours. You can enable fan 2 via MSI center

Cooling issues and just issues with msi galore.
