Hey 'sup,
Well a couple things...
One, that's not a cfl... just a tube flouro... you'd get much better light with a swirly-bulb type flourescent (which is what everyone on here refers to as a CFL) and that tube there may not be enough light for your plant.
The other is that the thermometer's probe will read more accurately if it hangs free in the air. Dark soil absorbs light and therefore heat... it might be reading high.
You want 'cool white' type lights right now in the seedling and then veg stage and you also need lots of ventilation. A fan blowing on the plant is a start, but you need a true exhaust to get you temps under control.
