I'm having trouble controlling the speed of the new fans I installed in my PC. I added five new fans, and while I could control their speeds at first, that functionality suddenly stopped. I'm using an Asus Prime B650M-R motherboard, an RTX 4070 Super graphics card, a Ryzen 5 8500G processor, and 32GB of RAM. The BIOS doesn't recognize the fans anymore; it just shows 'CHA FAN N/A.' Any advice?

If you're using a fan hub, remember that some hubs only support 3-pin fans, and they might not allow speed control at all. If you want precise speed control, it could be worth switching to PWM fans. Also, double-check all your connections and ensure everything's plugged in properly!
First off, are your fans PWM fans with a 4-pin connector? That could be essential for speed control. If you're using a fan hub, make sure it's compatible with PWM. Sometimes, if fans are 3-pin, they won't allow for speed adjustment in the BIOS. Check if your hub supports the type of fans you have.
