SilverStone Permafrost PF240W-ARGB


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 MX500
– HDD: WD 1 TB Blue
– PSU: Seasonic Snow Silent 750W Platinum
– Case: Phanteks Enthoo Luxe White
– Thermal compound: Noctua NT-H2


Software used for testing the cooler:

– AIDA64 Extreme Version: 6.30.5500
– 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.


Final thoughts

The Silverstone Permafrost PF240W-ARGB is a good AIO CPU cooler. The performance is great and the same can be said for the build quality. The noise output is on the high end of the spectrum. However, it is to be expected as the included fans are spinning at a maximum of 2200RPM.
The mounting system is very good, in fact, it is only bested by Noctua’s Secu Firm mounting system. The backplate is made out of metal and all components are solid and made out of metal, except the plastic made spacers.

The cooling performance is very good, thanks not only to the two high speed 120mm fans used, but also, thanks to the pump. Speaking of which, while the pump does spin at 3400RPM, the sound it generates is manageable, however, there is no way to control the pump speed without an external voltage controller.

The tube length of 400mm is ok for most systems, however, it will increase the overall difficulty of the installation process. This is because 400mm is a size that is right in between “too long” and “too short”. Too short to have the radiator installed at the front of a decently sized ATX case, and too long to have the radiator mounted right above the motherboard.

In conclusion, the Silverstone Permafrost PF240W-ARGB is a great CPU cooler that will deliver a good performance, with an average noise output. The addressable RGB integration is done with taste, and it is enhanced by the all-white matte coating present on most components of the cooler.
