REASONS TO AVOID
1. The default fan settings result in louder operation than necessary.
Silverstone’s IceMyst AIOs demonstrate that there is still ample opportunity for innovation within the CPU cooling industry. In addition to effectively cooling the CPU, this cooler offers the unique capability of adding multiple fans ($16 additional cost per fan) around the CPU block’s base, allowing for targeted airflow over components such as VRMs, RAM, SSD, and more. This exceptional feature sets it apart from any other product currently available on the market. Furthermore, the IceMyst coolers are priced lower than numerous high-end AIO cooler alternatives.
During our CPU cooling evaluations, the IceMyst AIOs (we examined both the 360 and 240mm variants) exhibited exceptional performance, consistently ranking among the top-performing coolers in terms of their ability to effectively cool the chips. Moreover, when all the coolers’ fans were adjusted to the same low noise level of 38.2 dBA, Silverston’s IceMyst 360 outperformed any other cooler we tested by efficiently managing 237 watts. Similarly, the 240mm model also showcased commendable performance by effectively handling 228W.
1. The sole issue I have encountered is that the pre-installed radiator fans of IceMyst tend to run louder than necessary, but this can be resolved by setting up a personalized fan curve. In case fan noise is a concern for you, rest assured that the 360mm IcyMyst delivers exceptional noise normalized performance when configured to run quietly, surpassing any other cooler available in the market.

REASONS TO BUY
1. Exceptional cooling performance with Intel’s i9-13900K, capable of handling up to 325W.
2. Includes a comprehensive software suite for easy customization.
3. Features a high-quality 2.1-inch IPS display.
4. Fan curves are tied to coolant temperature, ensuring efficient cooling.
5. Designed to accommodate tall RAM modules without obstruction.
REASONS TO AVOID
1. The 420mm radiator may limit compatibility with certain cases.
2. Considered expensive compared to other options.
The iCUE H170i Elite LCD XT AIO from Corsair provides exceptional cooling performance when paired with Intel’s i9-13900K processor. It effortlessly handles over 325W in our rigorous thermal tests, making it the top performer in our evaluations. What sets the H170i Elite apart from other coolers is its ability to adjust the noise level based on the CPU coolant temperature. This results in a quieter operation during everyday tasks and eliminates the annoying fan bursts. However, it’s worth noting that under sustained heavy workloads, the cooler tends to produce more noise, which we observed during our testing procedures.
The Corsair iCUE H170i Elite LCD XT stands out as a top-notch cooler in both performance and features. However, may be considered steep for some. Alternatively, Corsair offers the iCUE H170i Elite Capellix XT, which lacks the visually appealing 2.1-inch display but retains the same radiator and pump, at a more affordable.
That is still a significant sum of money for a cooler. However, if your requirements are demanding enough to justify a 420 mm radiator, you likely have the means to invest a little more in ensuring optimal cooling for your high-performance CPU during heavy usage.
That’s still no small amount of money for a cooler. But if your needs are extreme enough to warrant a 420 mm radiator, you can probably afford to spend a bit extra on keeping your powerful CPU as cool as it can be under load
