Don't Forget to Vacuum Out Your Servers

This weekend, I powered down my HA server to install a new disk and do my periodic server vacuuming. I have two 120mm fans in the case to keep things cool, so it pulls in a ton of dust that ends up resting on drives, cards and in the CPU heat sink. The CPU heat sink was especially caked and I had to blow it out using a can of compressed air. The clean heat sink makes a huge difference in the CPU temps - about a 10 degree difference as you can see in the graph below:
