  Decreasing the operation temperature of a Silicon Photo-Multiplier (SiPM)
leads to a drop in its dark noise. Some experiments consider cold temperatures
as an option for low noise applications of SiPM. One of those is the TAO
detector, which requires operation at $T\approx -50~^\circ$C. A significant
dependence of the Photon Detection Efficiency (PDE) of a SiPM on different
temperatures was reported with a drastic drop around this temperature. In this
paper, we present studies of performance for two samples of SiPMs from
Hamamatsu and AdvanSID(FBK) companies in a broad temperature range. No
significant difference for the PDE was observed.
