I recently upgraded from an i7-7700K with an EVGA cooler to a new i7-14700K using a Cooler Master 240L AIO cooler on an MSI Z790 motherboard. My old setup was super quiet, but now my PC sounds like a jet engine even when I consider it to be at 'idle'—I'm just browsing with about 60 Chrome tabs open. The old 7700K handled this without making a sound, but now the AIO fans are constantly spinning up. I've tried enabling 'Silent' mode in the MSI Center, adjusted fan curves, and confirmed that my case has good airflow, but the fan speeds are still around 1420 RPM just for everyday activities. Is this normal behavior for the 14700K? Should I reconsider using a 240mm AIO, or is there something specific I should check out?

Your i7-14700K is known for its aggressive boost behavior; it can pull a lot of power even during light tasks, which might explain the noise. You could also look into updating your BIOS and turning off any CPU boost features. If it's still warm, take a peek at your thermal paste to ensure it's applied correctly, but a steady temp of 45-55°C for idle isn't terrible.
Seriously, how do you manage to have 60 Chrome tabs open? That's a lot of resource usage! If you've got 32GB of RAM, why not, right? Just be careful with performance impacts.
It sounds like you just need to fine-tune your fan curves. With my AIO, my fans usually only spin at 500-600 RPM at idle, making them practically silent. If yours are revving up too much, you could check out some tutorials on how to adjust those. When set correctly, the fans shouldn't sound like a jet engine while you're just browsing.
First off, check your CPU temperatures. They might be higher than you think, causing the fans to ramp up. Also, consider disabling multicore enhancement in the BIOS; it can cause the CPU to draw excess voltage for minor boosts, leading to higher temperatures. If temps are okay, lowering the voltage or enabling Intel Baseline Profile might help with fan noise too, but remember a 240mm cooler may be on the smaller side for a chip like the 14700K.
