ARCTIC Freezer 4U-M (Rev. 2) for AMD: SP6, sTR5, SP3, TR4, sTRX4, sWRX8; Intel: LGA4189, LGA4710, LGA4677, 4U & UP, Server CPU Cooler, 2 x 120 mm fans, 400–2300 rpm, Rack Cooling Fan

Good. Great value for money. Very good cooling performance.

At max RPM it’s managed to keep the Epyc 7532 at a max of 43c in a 22c ambient room with poor airflow. At about 1000 RPM it maxes at 55c this test was done under full load. Attaching the cooler to the brackets isn’t like the usual consumer grade coolers, make sure you attach the brackets to the cooler first and the screws get screwed in from underneath to keep the bracket in place or at least for the AMD side of things. I tried attaching the brackets to the board and cooler after the fact and well, it was a lesson learned. Impressive cooler for impressive value. I was going to add my P12 Max fans to this but the fans that come with the cooler are more than adequate.

Using it to cool a 64 core Epyc socket SP3. The cooler is quiet and keeps the temperature of the CPU to a reasonable level. Fitting is releatively easy but you have to follow the instructions as everything needs to be positioned correctly depending on the exact setup you have. There is also an order required to tighten everything down to make sure that you get good, strong contact with the CPU, but everything is well shown in the instructions.

These heatsinks are massive and perform reasonably well, but oddly they don’t fully cover the CPU’s integrated heat spreader on an SP3 socket processor. I’m convinced they would cool far more effectively if they actually covered fully, just like every other heatsink I’ve installed over my 35 years as a computer engineer.

These are some fantastic coolers! The price might seems a bit high, but it's a right price for what it offers. I moved a Supermicro H11DSi-NT + 2 Epyc 7742 from a 2U rack server into a 4U/5U case and when running 100% these 2 keeps the CPUs around 65C. Yes, they both fit on this motherboard and yes you can still add/remove the RAM modules that are right under the heatsink. Even at full load these are incredibly quiet. The package includes thermal paste and the adapter for Xeon, which is a plus.

Kühlt hervorragend. Einbau ohne Anleitung schwierig. Habe meine KI gefragt.

Kyler riktigt bra, tysta fläktar.

fa il suo

Ciężki i duży, i dużo mniej solidnie i estetycznie wykonany niż Noctua ale tańszy i może być. Niestety wymaga dedykowanych, własnych wentylatorów.
