Liquid cooling can be great for keeping temps low, especially if you're running a powerful build or overclocking. As for maintenance, it’s not too bad—just make sure to check the coolant levels every so often, but you might not need to top it up yearly. Leaks are a concern, but as long as you go with a reliable brand and install it properly, the risk is minimal. It can perform better than air cooling in certain situations, but for most users, air cooling is usually enough and way less hassle.
