My Raspberry Pi 4 b had an average temperature of 107 F before installing heatsinks. It's now an average of 114 Q. No new loads were added. The only change was the addition of radiators. Could be coincidence, I don't know exactly. Since the temp is still pretty low I just add a fan and some monitoring and move on. YMMVEdit: Looks like the temperature change could be due to the Pi orientation change. It was vertical before I installed the heatsinks, and after I installed the heatsinks I oriented the Pi to a horizontal position. After writing the review I put it back in the same vertical position as before and the temperature dropped again. So it looks like the heatsink has no effect, at least under this kind of compute load.
