Salvaged the fan from an expired PSU and back to 31c now
see article http://www.codinghorror.com/blog/archives/000748.htmlManufacturers measure off quite a modest range of operating temperatures for hard drives, from +5 to +55°C as a rule, and occasionally to +60°C. This operating range is much lower than processors, video cards, or chipsets. Moreover, hard drive reliability depends heavily on their operating temperatures. According to our research, increasing HDD temperature by 5°C has the same effect on reliability as switching from 10% to 100% HDD workload. Each one-degree drop of HDD temperature is equivalent to a 10% increase of HDD service life.
