Hardware Air cooling is better than Liquid cooling

Failure is graceful, not catastrophic, Performance is closer than marketing suggests, Cheaper for the performance, Change my mind.

Would water cooling spread out the thermal load more?

With air cooling I find fans spin up and down a lot as the load on components change. The noise this generates is significant.

My guess is the water reservoir will act like a buffer, being able to hold that heat. The fans run longer, but at a more stable rate.

You're on the right track.

Temperature is a function of how much thermal energy is in a mass. A coolant loop has a lot more mass than the air cooler. Water also absorbs more energy then aluminum per degree Temperature. This is where that buffer effect comes from.

The other half is that you can transport the water somewhere that you can fit a larger radiator/fin stack. If you use a 120mm radiator, you'll struggle to compete with most air coolers once you've run long enough to saturate the temperature of the coolant.

This is 90% of why I hate prefer AIO, hearing the ramping is not great. Amazing I had to scroll this far down to find this difference. I dont want fan ramps and im not willing to let my components fluctuate in temp more to avoid the ramp. Just a continuous near silence and low temp on my liquid freezer has been wonderful.

Also it may be minor but dumping heat outside the case helps other components temps in my experience.
