What Buyers Say
What really stands out is how many users report this cooler 'exceeded expectations' for its cooling capabilities, often noting significant temperature drops compared to previous AIOs, even with demanding CPUs like the i9-14900K. The integrated VRM fan is a recurring highlight, praised for keeping motherboard components cool, which isn't a standard feature on many AIOs. However, the thick 38mm radiator is a consistent point of caution, with builders frequently mentioning tight fits and the need to double-check case compatibility before buying. The pre-wired fans are a blessing for some, but others found the stiff, long tubes and final fan mounting still required careful manipulation.
“Dude, this thing cools my 14900K like a champ, temps dropped like crazy, but seriously, measure your case twice because that thick radiator is no joke, I almost couldn't close the side panel.”
Common Praise
- Achieves 'massive thermal improvement' (up to -15°C under load) compared to older AIOs.
- The integrated VRM fan effectively cools motherboard voltage regulators, a unique and appreciated feature.
- Considered 'one of the best AIO coolers at affordable price point' for its performance.
- P12 Pro fans are 'quieter at full speed' than previous models.
- No proprietary connectors; uses standard 4-pin and 3-pin headers, making it easy to integrate.
- Pre-installed, pre-wired fans and daisy-chained cables simplify the setup process for the radiator fans.

Buying Guide
When you're looking at an AIO CPU cooler like this, you're essentially buying a self-contained liquid cooling system for your processor. The main goal is to move heat away from your CPU more efficiently than air cooling, especially for high-performance chips. Pay close attention to the radiator size and thickness, as this dictates if it'll even fit in your PC case. Also, consider extra features like a VRM fan, which helps cool other critical motherboard components, not just the CPU.
Radiator Size (e.g., 360mm)
This refers to the length of the radiator and how many fans it can accommodate (360mm usually means three 120mm fans). A larger radiator generally means more surface area for heat dissipation, leading to better cooling, like having a bigger car radiator for a more powerful engine.
Radiator Thickness (e.g., 38mm)
This is how deep the radiator is. A thicker radiator, like this one's 38mm, holds more coolant and has more fins, allowing for even better heat exchange. Think of it as a thicker sponge absorbing more water; it can absorb and release more heat, but it also takes up more space in your case.
VRM Fan
VRMs (Voltage Regulator Modules) are components on your motherboard that deliver power to your CPU and can get very hot. A dedicated VRM fan, like the 60mm one here, actively cools these components, preventing throttling and extending the lifespan of your motherboard, especially important for overclocking or high-end CPUs.
Contact Frame (for Intel)
Intel's LGA1700/1851 sockets can cause the CPU to slightly bend under the stock mounting pressure, leading to uneven contact with the cooler. A contact frame replaces the stock mechanism, ensuring more even pressure distribution across the CPU's IHS (Integrated Heat Spreader) for better thermal transfer and potentially longer CPU life.
Alternatives
If this 360mm AIO is too bulky, look for 240mm or 280mm AIOs with standard 27mm radiator thicknesses, or consider high-end air coolers if you don't need the absolute peak liquid cooling performance.
