Just bought the CLC-280. Although I've built several PCs, this will be my first liquid cooler. Watched a few videos on it but still not sure on a few things.
1 - Is the USB really needed? Seen conflicting reports that it's just for RGB, others say you need it to control fans and pump. I'm not a RGB fan, so was planning to keep this off. Can't I just let the mobo control the fans and not worry about the USB?
2 - Seen some users install the fans directly to the block assembly while others plug into the mobo. This may be in relation to my first question. Was planning on plugging directly into the block. Any issues with this?
If it helps, I have a i7-8700K, MSI Z370 Gaming Pro Carbon mobo, and Fractal Define R6 case (don't plan to use the included fan control). I won't be OC'ing at this time. Thought process was to get way more cooler than I need, turn the fans down low and forget about the thing all while keeping the temps low.
