I have never known RPM of a drive to affect its noise level. The fan(s) will be far more significant in noise level. Most drives run pretty quietly, though some can get noisy during I/O, like my HGST Ultrastar He6 drives.
Also, without knowing the model, I wouldn’t say they’re not made to run 24/7. But even on desktop drives, it’s rarely run time that kills them, it’s start-stop cycles. Everything will be fine, but one day you’ll shut it down and some drives won’t spin up. That’s why power outages can be deadly to an old server.

The “designed for 24/7” thing is a myth. Yes, some server/enterprise parts have a lower failure rate, but it has nothing to do with 8 hours a day vs 24.
Also, my setup is almost entirely the cheapest consumer drives available, and I’ve never had any significant failure rates outside of the one bad supplier. If you are seeing anything like that, you should examine your setup. I suspect you either have cooling issues or (more likely) vibration that’s causing premature failures.
