Silverstone’s Permafrost AIOs pack ARGB, a new block/pump design and automotive grade radiators

As previously reported at Computex 2019, Silverstone, a manufacturer of PC cases, components and accessories, will be launching a new range of ‘Permafrost' all-in-one liquid coolers very soon. With launch fast approaching, we now have more details on specs.

The Permafrost AIOs are packed with features, including integrated ARGB lighting on the water block and fans, an addressable RGB controller with 10 lighting modes and PWM controlled fans. The permafrost range comes in three versions- the PF12-ARGB has a 120mm radiator, the PF24-ARGB jumps up to 240mm and the PF360-ARGB sits at the top with a 360mm radiator.

Silverstone is one of a small number of all-in-one liquid cooler manufacturers which chose not to use an Aestek patented design. In fact, the new Permafrost line up incorporates a new water block featuring a multi chamber design which Silverstone says isolates hot and cold liquid channels to prevent heat bleeding, thus making the water block more efficient at dissipating heat.


The pump motor uses a three phase, six pole design to offer smooth and quiet operation compared to most single phase, four pole motors. This change should also make the pump more efficient. A copper thermal transfer plate sits below the pump housing and is equipped with 0.2mm micro channels to evenly distribute heat which, in turn, improves dissipation.

The Silverstone Permafrost series use ‘automotive grade' radiators, which should have excellent anti-corrosion properties and durability. The included ARGB PWM fans have ribbed blade edges to suppress turbulent air, meaning maximum performance with lowest possible noise. Fitted to the four corners of the fans are rubber pads which help keep vibration noise to a minimum.

With standard ARGB 3 pin connectors on the cables, connecting to a motherboard and synchronising the RGB lighting with other components should be simple. However, if your motherboard does not support ARGB connections then you can use the provided controller to adjust RGB colours and patterns.

KitGuru says: Who is looking forward to the new AIO line-up from Silverstone? We will be getting our hands on a sample soon, so be sure to look out for the review.
