The RGB Case Fan (Powerspec G434) with Lian Li label on the back of the PC is going out.

The back case fan is going out. It is randomly slowing down, making noise as it slows down.

I tried finding a replacement fan on Amazon and struck out 2 times. It appears the case fans use all 4 pins for both power and the RGB function. The only ones I found online that specifically said they were PWM RGB LED 12V and FAN 12V only use 3 pins of the 4 for the LED. The 3rd pin is blocked, yet on my motherboard, all 4 male pins are present and the current fans show all 4 female pins open.

SO, where do I get actual replacements for these 2 fans used in this case?

Thanks for any help you can offer.

Thank you very much! I sent you the mailing address in the email reply.

Everything is working great. I did have to reinstall the ASRRGBLED utility to get it to work with both the ARGB and the RGB onboard connectors. Thank you so very much for your help.

You can use the 3 pin fan, the header is keyed. However, a 4 pin fan is a PWM fan. For the RGB the 4 pin is RGB, the 3 pin is ARGB. Link what you're looking at and I'll check it out.

The header on the motherboard is definitely the 4-pin RGB. The Power cable and RGB cables from the fan are both 4-pin. It appears from the 4-pin connector that is plugged into the RGB port (to the right of the open 3 pin ARGB header) that they used a combined connector that comes from both rear case fans. You can see from the video how the lower fan is really dragging. I pulled it out and used compressed air on it to see if dust was blocking the fan. After running at normal speed for about 5 minutes, it just slowed back down. I very much appreciate your help. If you need further information, please let me know.

It's RGB. The 4 pin RGB is just for the RGB functionality. There should be another fan power cable that's the 4 pin PWM. I doubt we'll have any of the old RGB fans, but I don't mind giving away some ARGB fans to replace them. Let me shoot you an email for your address.

Hello, I'm having similar issues with my 2 fans. Can I get the ARGB or provide an Amazon link to buy same? Thanks!

Sure, they're OEM. What color? Black or White?
