Freezer 4U SP3

Compact 4U Server Cooler

Technical specifications & manual

Designed for EPYC processors

The Freezer 4U SP3 is specially designed for Socket SP3 EPYC processors, but due to its design it is also compatible with Threadripper CPUs of the Naples, Rom and Milan families on TR4/sTRX4/sWRX8 sockets. With a maximum power consumption of only 2.88 W, the Freezer 4U cools even the most powerful AMD processors with 64 cores and 280 W TDP extremely efficiently.

Compact design - optimal compatibility

With its compact dimensions of just 156 x 124 mm, the Freezer 4U does not protrude above the memory banks or components in the socket area, making it suitable for dual-socket motherboards. The installation height of the Freezer 4U SP3 is only 152 mm, which means that it fits into classic 4U server racks as well as into most consumer 4U cases available on the market.

Powerful fans in push-pull configuration

The installed PWM fans benefit from all the advantages of the award-winning P series. Designed for static pressure, the fans are ideal for the Freezer 4U SP3's high fin density and provide efficient heat dissipation in push-pull mode, even in power-hungry applications. Especially office workstations benefit from the quiet fans. The dual configuration also allows for inherent redundancy and protects the system from total shutdown caused by heat.

Designed for continuous operation

Both fans of the Freezer 4U SP3 are equipped with dual ball bearings, which allows for 24/7 continuous operation without the slightest compromise in performance. This type of bearing is much more resistant to contamination and wear caused by high temperatures than conventional sleeve or ball bearings and is therefore the perfect choice if you want to ensure fault-free continuous operation.

Premium thermal paste included

The Freezer 4U SP3 comes with MX-5 thermal paste. Thanks to its low viscosity and particle size, ARCTIC's Ultimate Performance thermal paste enables a very thin layer thickness and significantly reduces the heat build-up between the heat spreader of the CPU and the cooler. The thermal paste is neither conductive nor capacitive and is therefore absolutely safe to use.
