I need some advice about my PC setup. I have a Corsair mATX 2500x case with a TUF RTX 5090 GPU. My cooling setup includes three intake fans at the bottom beneath the GPU and two on the side. For exhaust, I have three fans at the top along with an AIO cooler and one at the rear. The problem is that the GPU is touching the frames of the bottom case fans, though the blades are not touching each other. My temperatures are fine, sitting between 60-70°C under load, but I've noticed some buzzing noises and vibrations. I've kept the bottom fans at a low RPM to manage noise. I'm worried about potential long-term damage due to the vibrations. Should I remove the fans or leave them as is? If I do remove them, would my temperatures increase?

Regular case fans are usually about 25mm thick, but you can find 15mm slim fans that could give you some extra space.
I wouldn't feel comfortable with the GPU and fans touching at all. Is there any chance to space them out somehow? You could use a sag bracket if the GPU is sagging. The buzzing might mean the fan blades are touching something, which isn’t great.
Unfortunately, there's no way to space them out, there's just no room in there.
I have Corsair ICUE link RX120mm fans that are daisy-chained. I thought about looking into AF120mm slim fans, but since this is my first PC build, can I still daisy-chain them? How would the wiring work?
