Liquid cooling isn't saying anything. There's no difference in liquid or air in their respective ranges. A 120mm Corsair H60 gets near identical temps to a CM hyper212 evo for instance. So there's quite a variety of what liquid can mean. It's only real advantage is in the largest coolers, 280mm/360mm, which have a considerably higher capacity than any aircooler could possibly have.
So on a cpu like the 9900k, even at stock settings, you should have a minimum of a decent 240mm (@ 200w ish area) with better results from a 280mm/360mm rad. If you are using a 140mm that's OK, but a 120mm isn't, it's barely rated at what would be considered a stock cooler.
So that in itself can and will affect temps.
