because you have the vents open on the bunsen burner the flame is getting more oxygen, making it hotter.

What happens when a Bunsen burner air hole is half open?
When the air hole is opened completely then the flame would turn blue indicating it is very hot. If you closed it the flame will be yellow indicating that it is not as hot (also called the safety flame). So if you half opened the hole then the flame would be hot but not as hot as the blue flame, due to the air flow mixing with the gas inside.
