  A quantum absorption refrigerator driven by noise is studied with the purpose
of determining the limitations of cooling to absolute zero. The model consists
of a working medium coupled simultaneously to hot, cold and noise baths.
Explicit expressions for the cooling power are obtained for Gaussian and
Poisson white noise. The quantum model is consistent with the first and second
laws of thermodynamics. The third law is quantified, the cooling power J_c
vanishes as J_c proportional to T_c^{alpha}, when T_c approach 0, where alpha
=d+1 for dissipation by emission and absorption of quanta described by a linear
coupling to a thermal bosonic field, where d is the dimension of the bath.
