I had an issue today where I was stuck with a non-functioning board and 3 power supplies. I couldn't get any response from the board regardless of which power supply unit I was using. However, while the board is new, the power supplies weren't and I really had no way to isolate the issue between the two. Rather than messing with my existing systems, I wanted to test the power supplies without having to connect them to the motherboard.

Following my recent adventures with my motherboard, I wanted to set up a temperature sensor on my Kubuntu desktop, so that I could keep an eye on my motherboard temperature. Searching the repository came up with a number of potential options including ksensors. However, when I installed ksensors I couldn't find a temperature option; just memory usage and stuff.

Earlier today, I found that one of my boxen had hung. I tried restarting it, but was met with a keening siren alarm from my motherboard. Giving it a rest and restarting was either producing the same siren or a hang after a few minutes along with some nifty monitor graffiti.

I had to clean everything inside my PC today due to heavy dust accumulation and in the process remove the processor fan to clean it and the heatsink below it. However, while I usually mark the "right side up" for the fan, I'd forgotten to do so this time. While it made sense to keep the AMD logo on top, I was still not confident to start the PC without being completely sure. Google spouted advice hither and thither, but the general consensus appeared to be as follows:

• CPU fans should blow air into the heatsink.
• Case fans should bring cool air into the cabinet.
