cirrus7 nimbus – Extended and Extreme-Edition are now available!

While the Standard Edition of the cirrus⁷ nimbus offers good cooling performance for everyday desktop work – there are still application scenarios that require better cooling performance.

The Extended Edition and Extreme Edition are especially suitable for this. The former is designed to handle CPU-demanding applications that generate a permanent load. This includes, for instance, the permanent operation of several virtual machines and 3D rendering.

The latter goes one step further and offers cooling even for synthetic loads and number-crunching tasks that permanently require all units of the CPU.

Due to the modular design of the cirrus ⁷ nimbus , the cooling capacity can be increased simply by adding additional cooling layers. This principle is already used in the standard edition demonstrated on CPUs with 45W TDP , in which we use one more layer to compensate for the extra waste heat compared to the 35W TDP CPUs. Depending on the configured CPU, the standard edition is 51mm or 63mm high.

Extended Edition and Extreme Edition in Comparison

In the Extended Edition we install 3 additional layers, in the Extreme Edition there are 5.
But that’s not the only way to improve cooling performance. In addition, improved heat spreaders are also used. (With the heat spreader, the heat is transferred from the CPU directly to the cooling fins.) In the standard edition, the heat spreader consists of 3-layer 6mm thick aluminum. In the Extended and Extreme Edition, the Heat Spreader is milled from solid material . This ensures improved heat transport. The Extreme Edition uses solid copper instead of aluminum to maximize heat conduction. The copper heat spreader has a weight of 1.2Kg.
