Review on Enhance PC Cooling with uphere 120mm White Case Fan - Long Life 3-Pack (12WT3-3) by Joel Gumbiner

I have used them in my refrigerated trailer by connecting them to my constant power supply so they work when the fridge is on. They circulate the air and cool the entire fridge from top to bottom, making my refrigerated trailer economical to run and cooler. I took the steak out of the freezer the night before and 12 hours later it's still more than half frozen; before things are thawed overnight.
