PC Meltdown

The good – Disaster averted

The bad – Relying on cheap fans to cool PC components

The ugly – I feared the worst

 

I had two fans fail, virtually simultaneously (I believe), in my Windows PC. One was the primary (rear) case fan, an Antec TriCool 120mm. The other was the cheap manufacturer-installed 40mm fan designed to cool the Northbridge chip on my MSI K8N Neo4 Platinum/SLI motherboard. Both fans had been performing without issue since I built this PC in 2005.

Instant failure without warning
I don’t know exactly when these fans actually quit functioning. My first, and only, warning was noise coming from the PC. I traced it to the primary case fan, and noticed that it was not running at its normal constant speed. I then looked at the temperature readings provided by sensors built into the PC’s components, and two others provided with the PC case, an Antec P160. I saw the temperatures rising and immediately tried to save the data file I was working on, before shutting down the PC, but the system shut itself down before I could do so.
