Welcome back, deep divers. Last week, we talked about air and liquid cooling options for your PC. This time we'll dig a little deeper into all-in-one liquid cooling loops, the middle ground between air coolers and fully custom liquid cooling loops.
I mentioned that a good liquid-cooling loop will have better performance than all but the best air coolers, but Tested member Sweetz brings up an excellent point:
The thing about the closed loop coolers is that they have smaller thermal range and nonlinear cooling performance as compared to air coolers. Meaning that at CPU idle, when not stressed, they'll generally produce higher temperatures than competitive air coolers. However, when stressed, they can produce lower temps than the same air coolers that outperformed them at idle - again because they have a different thermal performance curve vs air coolers. You have to get used to this quirk when comparing them to air coolers. Ultimately, I believe lower highs are better than lower lows.
Large radiators do allow lower fan speeds than the entry level models, but the entry level models already allow lower fan speeds than many air coolers in the same price range. Given that air coolers in the same price range is what they'll be shopped against, I'm not sure I see their noise levels vs larger, more expensive water cooling systems as an argument for not buying the entry level models.
Choosing a cooler has a lot to do with your specific case. The all-in-ones with the best performance also have the most radiator area, and they won't necessarily work with every case. If you're building a new computer, of course, you get to choose a case and cooler at the same time, so make sure they're compatible.
Let's dive even deeper into the world of all-in-one coolers and discuss the nuances of radiator placement and airflow.
