My ARM fleet

[Dirk Broer]

Today the Raspberry Pi CM4 was handed to the active fleet by the Fleet's experimental branch, but grudgingly. The experimental department is not happy with the speed -stock @1500 MHz- and the chosen cooling solution, a 140mm Noctua Redux

blowing over the CPU, but in this case helped by a Xigmatek Porter N881 chipset cooler on top of the CPU. But just not fastened as the experimental department would have had it.
There are plans to mount a Noctua NC-U6 or a PCCooler HB-802, but the experimental department is still looking for a way to securely fasten the cooler to the module/IO board combo. Soon as that happens, 2300 MHz is the very least the Fleet hopes for.

Next launch will be the Rock Pi 4B, in its metal passive cooling case:

The experimental branch is planning an old Pentium Pro cooler as footing, aided by a 40mm Noctua @5V blowing through it. On top they are thinking of a 80mm Noctua @3.3V, to suck hot air out.

All this will mean the end of active service for the old LeMaker Banana Pro, and now the Raspberry Pi 2s and the Banana Pi M2 come in the danger zone. The Raspberries get a chance with Ice Tower coolers to crank up their daily score and their maximum MHz limit, but the Banana Pi M2 already has an even better cooler and has to try to get overclocked to somewhere in the 1200 MHz.
