Testing a power supply without a motherboard

Submitted by Druss on Sun, 2007-12-09 04:26

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 was new, the power supplies weren't and I really had no way to isolate the issue between the two. Rather than messing with any of my working systems, I wanted to test the PSUs without having to connect them to a motherboard.

Setting up temperature sensors with Ksysguard

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.

Should processor fans blow out or in?

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.
