In the market we can find a large number of heat sink manufacturers, but not all of them offer us the same confidence that they can offer us. ARCTICa German company with more than 20 years on the market and which focuses its main activity on cooling systems for PCs and servers.
The wide range of server heat sinks ARCTIC seeks to cover all needs, from users who get the most out of the power of all their equipment to those looking for as little noise as possible. To the more than extensive catalog of CPU heatsinks, this manufacturer has just added two new models: Freezer 4U-SP5 Yes Freezer 4U-M Rev 2which ones we are going to show you now.
ARCTIC Freezer 4U-SP5, a heat sink for two processors
If we talk about the Freezer 4U-SP5, we are talking about a heat sink designed specifically for the range of EPYC processors
Just think that a single AMD EPYC processor already generates an incredible amount of heat, so imagine how good and efficient this new ARCTIC heatsink must be to be able to cool two processors simultaneously without problem.
To do this, the heatsink mounts a huge block of aluminum sheets soldered to a total of 10 heat pipes which, as you can see in the images, are separated into two zones to divide five for each of the processors. It is important that the aluminum sheets are soldered to the heat pipes, because as you have already seen in the images, the Freezer 4U-SP5 has two fans in push-pull configuration, one introducing air and the other removing it to create a turbine effect which significantly increases cooling efficiency.
These two fans measure 120mm in diameter, feature double ball bearings and of course have PWM controlled operation. They are capable of operating from 300 to 3,300 rpm in speed, emitting a maximum of 40 dBA of noise, and have the distinction of being designed to operate 24/7 for years, unlike most standard PC fans.
Finally, it should be noted that the ARCTIC Freezer 4U-SP5 is designed, as the name suggests, for large 4U servers, since due to its dimensions it would not fit in smaller servers (of Plus, it weighs no less than 1,512 grams). It also benefits from a 6-year warranty, which is standard for all ARCTIC products.
ARCTIC Freezer 4U-M REV. 2, maximum performance without compromise
This heatsink is not really new, but rather a revised version of the Freezer 4U-M, which is characterized by offering excellent performance in cooling tasks in both server processors. Intel Xeon as in the EPYC from AMD. This model is also compatible with ARM series processors. Ampere Other
Specifically, the revised version of the Freezer 4U-M heatsink is compatible with sockets LGA4189 Yes LGA4677 from Intel and with SP6, sRT5, SP3 Yes TR4 from AMD. Like the Freezer 4U-SP5, this heatsink also integrates two 120 mm PWM fans which cool a tower-shaped block of aluminum sheets, welded in this case to eight copper heat pipes. As you can see in the image, in this case the eight heat pipes go to the center, since it is designed for a single processor and not two like the previous one.
Being a heatsink for a single processor, it is a little smaller and lighter (1,275 grams) than the previous one, but it is still a monster with 8 heat pipes which in this case is designed to offer maximum performance without compromise . Its fans generate a maximum noise of 40 dBA and move at a speed between 400 and 2,300 rpm, controlled by PWM. It also benefits from a 6-year warranty, like all products from this manufacturer.
He mounting kit To use this heat sink with ARM Ampere Alta and Ampere Altra Max processors, it has dimensions of 160 mm long, 110 mm wide and 25 mm high with a total weight of 56 grams which must be added to that of the heat sink.
