Meltdown at CFDEV

Updated on November 14, 2023

We just found out earlier this week that one of the CPU fans on our main web server which hosts cfdev (I no longer operate this site), this site, and a number of other sites had burnt out. We think that the fan has been out for a while, and had been causing some strange crashes on the weekends when the AC is not as cold in our building. Hopefully the CPU is not damaged - it appears that it still works but once the new fan arrives we will have to do some testing.

So we now run lm_sensors, and if your servers running linux I would recommend you do the same. Most modern motherboards provide CPU temperatures and fan speeds often found in the BIOS, but you can also get this info from OS.

Here's a good article on lm_sensors from the linux journal:

Our next step is to find or write some software to automate this monitoring process, and send out alerts. Anyone know of any?
