cpu fan runs at 1800 rpm all the time

[GM2533]

Hello,

I am the owner of the OMEN by HP 25L GT15-0000i gaming PC and I have just noticed that the CPU fan is now always running at a speed of 1800 rpm: is this normal on this model or is the motherboard no longer able to detect this speed and therefore this figure does not correspond to anything real ?

I would like to point out that there is never any overheating, I am attaching a screenshot below.

Or HP has simplified the cooling on this type of PC, allowing the speeds of the input and output fans to vary and considering that this was sufficient (I should point out that the PC remains at very reasonable temperatures even when I use, for example, Handbrake or Lightroom).

I thank you in advance for any feedback regarding this issue.

Best regards

Hi @GM2533 

I do not think it is necessary to go faster fan if the temperature is as I see in the image of 27 degrees, the fans generally go faster with the temperature above 50 degrees.

Hello Resistantia,

First of all, thank you for your reply, but I'm not really worried about temperatures between 25 and 30°C.

I just wanted to know if other users have CPU fan speed sensors to help me assess whether or not I have a problem with my PC.

And does your CPU fan speed vary or stay fixed like mine, at 1800 rpm or something else ?

there is a sensor but if the temperature is not higher than 50 degrees you will not see the rpm increase.

The problem is that I don't have a sensor or I have a technical issue with my PC: I have the HWMonitor program (PS: I chose the portable version of this program) and it does detect the fan on my Nvidia card, but nothing for the CPU fan.

So I have confirmation that my motherboard isn't detecting this fan.

If I'm not exaggerating, may I ask what speed is listed for the CPU fan in the Omen Gaming Hub program in rpm for you? You have to go to the performance monitoring section.

That would help me a lot for the future.

Have a good day.

The sensor works, the OMEN Gaming is visible, not all programs can be compatible with the fan sensor.

[GM2533 · Accepted solution]

and Omen Gaming Hub gives you what rpm speed for the CPU fan?

Is this number variable for you or fixed like mine?

Until I get this information from another HP Omen user, I still don't know more 😭

It would be very nice if you could clarify this for me and I could mark my topic as resolved

Hello,

I'm going to mark the problem as solved, even though it isn't: I tried to find out how fast the CPU fan was running, as mine was between 1700 and 1800 rpm (I checked), and unfortunately no one gave me a concrete answer to that question.

Obviously, it started as a separate question, which evolved based on the answers I very kindly received from Resistencia, whom I thank.

I'm taking my PC in for repair at HP.

Sincerely,
