My graphics card is running hot and the fans are spinning at high speed. If I replace the case fans that bring air in and push air out, could that help solve the problem? When I opened the side panel, it immediately became much quieter, but the temperature stayed about the same.
Which fans should I look at if that is an option?
Kind regards,
Oscar R

That is correct.
Please mind you that 3-pin cooling fans use voltage regulation (DC) to control speed, which is simpler but less precise, often limited to higher minimum speeds. On the other hand, 4-pin fans feature Pulse Width Modulation (PWM), which provides better control, lower minimum RPM, quieter operation, and better responsiveness by using a dedicated wire for speed management.

Welcome to our HP Community forum!
Yes, you can almost always 'mod'/improve the airflow through your case.
I need to know what model PC you are referring to. Please type in: System Information in your lower Windows search bar, click on the System Information app, and look to the right of "System Model" and "System SKU" and provide that information.

Hello,
Thanks for the respond. I forgot to put the info -.-'
Here are the information:
Computermodell OMEN 30L Desktop GT13-1000a
System-SKU - 4K231EA#UUW
And I have ordered the Cooler Master MasterBox 600 Mid Tower in white for a chassiswap. What i understand my components will fit. I will do this for better airflow thru the chassi 🙂

Thank you for the additional information!
Here are two YouTube instructional videos of sorts to improve case airflow cooling in your OMEN 30L Desktop GT13-1xxx, which should be helpful: How to: Install and Setup All Fans in an HP Omen 25L / 30L! Tutorial & Guide! and: https://www.youtube.com/watch?v=XvIstFnl4Lk.

Thank you for the support and the links! However, in the video where he replaces the fans, his graphics card is about 50% shorter than mine. I’ll send a picture later. I’m going to change the case anyway and get a new, slightly larger graphics card that won’t fit in the Omen case.

I’ve started the chassis swap, and I can’t in any way mount the CPU cooler, so I’m going to have to buy a new one.
I also have a question about the RGB — HP has that little “RGB card” that I also can’t mount. Do I need it for the RGB to work in the new case?
The case is an Asus A23 RGB White.
I don't know if this is to any help or something or just raises other questions

You're welcome -and yes, given the case-size restrictions of an OMEN 30L Desktop GT13-1xxx, a smaller-sized (dual fan) graphics card model is recommended.
[EDIT:] The little “RGB card” as you called it, is specific for the HP RGB cooling fans. If you transferred those fans as well, you'll need this RGB controller too. However, many people switch (RGB) cooling fans and use a different RGB/ARGB controller such as the Corsair Commander Duo iCUE Link RGB Lighting and PWM ARGB Fan Controller.

understand, thank you!
I’ve run into a problem now. The fan connector on the motherboard is 4-pin, the new fans are 3-pin but in a 4-pin connector where the second-to-last pin is blocked. Can this be used as it is?

That is a new one for me: "3-pin but in a 4-pin connector where the second-to-last pin is blocked".
This sounds like you can't plug these fans into a 4-pin fan power connector.
I would go for standard edition 4-pin cooling fans.
