Yamaha r125 2012 [Coolant/overheating] problem

Hi guys,
So week ago i was riding in city was stuck in traffic and the red light popped up but the traffic started moving so i moved aswell and was going [trying not to rev engine to much but kept going because there was no where to stop] and it went off and about 30 min later was riding and the light again showed so i stopped on side and turn the engine off but left ignition on and the fan was like working loud to cool down.
I went home after it cooled and i checked the coolant level and the coolant was 4/5 so it was under full but way above minimum, i checked the hose all the way to end and there was no leaks or so ever.
Today i gave it a go [to college] and i got to college about 30 min riding and there was no light or anything but when i stopped the fan worked for about 1 min and went of, going back to college i stopped on petrol station to fill it with petrol and when i stopped the fan was also working no light anything, and then i went home and there was no light and when i stopped at house there was no fan working on.
But for sure its overheating [or maybe not overheating because the light doesnt come up but its getting hot quicker than before, because during summer i was riding for up to 4 hours daily and nothing and now when its cold weather it gets hot quick.

Question : What should i do/ inspect to fix this heating issue ?
One thing i checked is coolant level and hose if it has any leaks but it doesn't. So what should i check maybe its something with this radiator/fan/air cooler that is in front above front wheel, it has like metal cap and warning not to open when hot and i read also that its under pressure or something so i dont wanna make it worse as i dont know much about this radiator how it works and that so i would rather ask you guys

[One quesiton off topic, what gloves would you recommend me? doesnt need to be winter gloves or anything just gloves so they protect and also keep a bit warm. i found '' Scorpion Talon Gloves Black '' they look pretty cool and good opinions what do you think Confused

Thanks for helping !

What light exactly? Bikes do not normally have an overheating light. To my knowledge a red led on the dash is normally oil pressure/level

The bike getting warm while slow moving and the fan coming on is normal. Fan staying on after you turn the engine off is also normal, however a bit odd in November. What does the temp gage say?

The red light means 'coolant temperature warning' i checked in manual book, yeah i know its normal but its cold and also before even after 2 hour ride the fan didnt turned on. and i think i dont have temp gage
