• Cooler?

  Replacing that 60mm rear fan by two stronger ones (effectively quadruplung air throughput there) helped a bit. With those, I now get the open-case temperatures now also with a closed case. But I a...

• Cooler?

  Thermal paste vs. pad doesn't make much of a difference for me. With the case closed, the CPU temperatur goes to 105°C. IMO, the current CPU cooler is not very well suited for a rack case: It...

• Cooler?

  I remember someone doing some experiments using IBM Power 9 CPUs. Basically, thermal paste was much better than common termal pads, and indium termal pads were slightly better than pastes. Personal...

• Cooler?

  My case is 3U, so a 4U coller wouldn't fit. Also, I don't know of any place to buy an air cooler that would fit here, so I can't really change the cooloer. For now, the case is open top sitting on ...

• Cooler?

  True, similar here, with "sensors". I also have one sensor per NVMe SSD, and also one for my NIC. Apparently, the "apm_xgene-isa-0000" is the CPU sensor. By high system load for a dozen minutes, f...

• Cooler?

  Surprisingly, the cooler is not as noisy, as I'd have expected given its size vs. the TDP. Sometimes is swithces on-an-off every few seconds, which is annoying, but otherwise the noise is fine. D...

• Usernames on the BMC

  In the web interface, one logs in as user "admin". Via ssh, as "sysadmin". Is it possible to change those usernames, maybe make them the same? Why are they different in the first place? Also, why ...

• How to install Debian GNU/Linux?

  That indeed works for me, but only if I do not encrypt the root filesystem - otherwise the kernel hangs on boot. Anyway, I got my AADK now running Debian GNU/LInux. Hope it survives future grub upd...

  I've tried to install Debian GNU/Linux 12.2.0 on the Ampere Altra Dev Kit I got today. However, for me each installation attempt fails when the installer tries to install grub (i.e. just ebfore th...

• Cooler?

  While I'm waiting for my Ampere Altra dev kit to arrive: The CPU cooler looks small. How well does it work for you? How loud is the fan? Are there any non-water alternatives? Are there any compat...
