Hi,
Only recently discovered these apps for controlling the fans in your computer. can be set to manual speed or set to a schedule or manually turn on full to cool down during a break etc.
Macs Fans Control... free version does most of what you need

For PC...
AngusMonitor... about $12/ £10 a year, or less for 3 years sub

Obviously be careful and keep an eye on the temp display. both apps have a temp display so keep checking especially when you start to use them and get an idea of what temps you're running!!!
