Technical Fluid temperature
Hi and welcome 
Presumably engine coolant?
Probably thermostat failing.
No biggie, it's a routine consumable item and not a big job.
As they age the rubber seal starts to leak, causing it to run cool.
There's an easy way to check: start the engine from cold and feel the hose coming out of the top of the radiator. It should stay cool for a few minutes. If you feel the under side of the hose getting warm within a couple of minutes then the thermostat is leaking.
When replacing, make sure you get one with a metal pipe, not plastic.
