Am I falling foul of a myth...?
I thought it would be better to share this here since it relates more to CPU performance. If moderators disagree, please relocate it to Cooling. I don’t want to risk their attention by posting it there either. My current processor is a Ryzen 7 series, and I’m curious whether my views on cooling being limited to top-tier CPUs are accurate. While I acknowledge my Dark Rock 4 Pro is powerful, the idea of AI-Optimized or closed-loop cooling has intrigued me for some time. What do you think?
The specific model you're referring to is likely the Arctic 280 RAD or DeepCool LT520 RAD. These are affordable options suitable for your needs.
Liquid cooling is like air cooling. You have a whole range of offerings that cover a variety of use cases, so no it isn't reserved for high end. For example, I recently transplanted a system into a micro-ATX cube. I always had problems with cooling in that case, as it was height restrictive and you simply can't put a big air cooler in it. In the latest build I went for a 120mm AIO. The performance of it isn't great, but it compares well to the air coolers I could fit. Personally I don't like running liquid nowadays. AIOs aren't bad but can fail after some years. Custom loops will be much higher cost and may require more maintenance. If space doesn't constrain, I'd rather just throw on a Noctua D15 and I'm done. The last bigger AIO I had was a CoolerMaster 240mm, and depending on the CPU it actually performed a little better than the D15, presuming because of contact area and on air, how the heatpipes were distributed. Trading off that you have pump vibration added into the mix, and the supplied fans were pretty noisy.
If you're considering this, keep in mind the initial price is higher and AIOs tend to wear out faster, usually needing replacement every 3-5 years. Making custom builds is a passion for some PC enthusiasts. It's often seen as a premium choice mainly because those extra $20-50 could have gone toward a better processor. You're not limited to high-end parts, but it's worth noting. Ultimately, just enjoy the process!
I've experienced both AIOs and premium air coolers before. It's clear to me that a basic or mid-range AIO falls short compared to high-end cooling solutions. If thermal performance matters, don't cut corners. In terms of durability, I've only encountered one AIO failure over ten years. While this is personal experience, modern CPU thermal protection and the substantial heat absorption even after damage mean you're unlikely to cause any issues. I haven't noticed any leaks with my 120mm models, though they can be useful in tight spaces. For top-tier CPUs, I usually suggest going for 280mm or larger, or better yet, 360mm or more.
You only need a contemporary heatsink. It works well with your 5600X, 5900X, and semi-passive setups across different speeds, and you won’t have to use a fan on the heatsinks. Still, for fairness, I’m using an airflow-focused chassis—though it can be in its standard setup with two fans.
You're looking for the source of the three-year figure and also checking if a 420mm AIO has comparable cooling options.
With a powerful CPU handling heavy tasks, you'd be fortunate to last three years.
The unit should operate at a consistent speed to maximize its lifespan. Power consumption and heat generation shouldn’t be a concern unless using an extremely inexpensive pump or small heater. Wrong installation can lead to significantly increased wear, especially on pumps—this is the main reason AIOs often fail, including my own experience. I’m not trying to persuade you otherwise; I’d appreciate seeing some data. For example, Arctic Freezer provides a six-year warranty on their AIOs, showing at least one maker values double that for reliability.
