Iceberg Thermal IceSLEET X5


The following system was used to test the cooler:
– Processor: Intel i9 9900K @ 5GHz
– Motherboard: ASRock Z390 Phantom Gaming X
– GPU: MSI GeForce RTX 2070 Super Gaming X Trio
– SSD: Crucial p5 500GB
– PSU: Seasonic Snow Silent 750W Platinum
– Case: be quiet! Silent Base 802 White
– Thermal compound: Noctua NT-H2


Software used for testing the cooler:

– AIDA64 Extreme Version: 6.32.5600
– Intel Burn Test v2.54
– Prime95 29.1

The cooler was tested with the CPU at the default turbo frequency of 4.9 GHz and overclocked to 5 GHz with a core voltage of 1.261 V.
Also, the included fans have been used at their maximum speed.
The room temperature was approximately 26°C (78°F), with 2°C margin of error.
The idle test consists of the CPU sitting idle at the desktop for 30 minutes, the temperature was measured at the end of the test.


The settings of the software used are the following:
Intel Burn Test v2.54 – Stress level: Maximum
Prime95 29.1- small FFT
AIDA64 Extreme Version – FPU Benchmark & Temperature monitoring.
Each test was conducted for 40 minutes.




Full Load – IntelBurnTestV2


Full Load – AIDA64 CPU, FPU & Cache


The noise level was measured at three different distances from the fans (10cm, 20cm, 30cm.) the noise was measured with a margin of error of ± 2 db.


The IceSLEET X5 has a good clearance for the RAM slots, thanks to its offset design. This pushes the whole fan and cooler assembly away from the RAM slots.


The PCIe expansion slot clearance is average at best, with around 20mm of space between the graphics card and the side of the cooler. This would have been good for a large heatsink, however the IceSLEET X5 is not a large cooler.


Final thoughts

The IceSLEET X5 is a unique CPU cooler, and that is thanks to its different color and the shape of the shroud. The main purpose of this CPU cooler is to offer an adequate cooling performance while looking different. This CPU cooler, while it can handle an i9 9900K processor, it is not recommended for such a high TDP. The IceSLEET X5 would be best suited on a mid-range gaming system that has as its focus gaming performance and looks.

The IceSLEET X5 is priced at around 55 USD or EUR, it should have been around 40 USD or EUR to be competitive. The main issues with this CPU cooler are down to the fan, its impeller design is not the best for delivering a good static pressure. However, the biggest drawback of this fan is that it cannot be replaced and the only thing holding it attached to the heatsink are four small plastic clips

The cooling performance is adequate, the CPU reached a maximum temperature of 94°C while being overclocked to 5GHz. This makes the IceSLEET X5 around 1°C warmer than the IceSLEET X6. In addition, the noise performance is not the best either, as the maximum noise output of this CPU cooler is 43 db.

In contrast, the build quality is very good, almost on the same level as the high-end air CPU coolers from the main manufacturers. The baseplate has a smooth surface, and the cooling fins have a good finish on the edges.

The installation process is very simple and the mounting system is very good. It uses a minimum of plastic in its construction and all components are well made.

The IceSLEET X5 much like the rest of the IceSLEET series is a good concept that needs more work. The main issue that needs addressing is the fan, it is not good enough to be competitive especially for the asked price.

The fan and heatsink shroud while well made, do not aid with the cooling of the CPU, not only that, but the panel gap between these two plastic pieces is uneven.

In conclusion, the IceSLEET X5 is a good-looking CPU cooler that offers a good cooling performance on a mid-range CPU. Overclocking on a high TDP CPU is not recommended, as the cooler is unable to dissipate that level of heat. The mounting system is very good and solid and the user manual is well made. The main purpose of this CPU cooler is to offer an adequate cooling while having a different design with a unique color.
