Judging a temperature by how it feels is always so unreliable. Half the time I touch the water in my tanks and think, "Oh my god, it's so hot the heater must be malfunctioning!" and when I check it's 78. Other times, I feel the water and it feels ice cold, but the temperature reads 80. It all depends on what your room temp is, how cold you feel (ie if your hands are cold, the water will feel warmer than it normally would), etc.
