look better and you will notice lines like the following:
Thermalization: T ( 544.6K) reduced by -2.000
The temperature is free, not fixed, so it may go up and down, but
the overall trend will be down.

There is also the possibility to rescale the temperature by a fixed
factor ('rescale-T' and delta_t < 1). If you do not like how these
options work, you can easily modify them: "apply_thermostat"
routine in PW/dynamics_module.f90
