1. A method for testing a closed cooling loop for leaks, the method comprising:
causing air to be pumped into the cooling loop;
measuring an initial internal temperature and an initial internal pressure of the cooling loop to identify an initial internal temperature value and an initial internal pressure value of the cooling loop;
in response to a predetermined amount of time passing since the air was pumped into the cooling loop, measuring an updated internal temperature reading and an updated internal pressure of the cooling loop to identify an updated internal temperature value and an updated internal pressure value of the cooling loop;
using (i) the initial internal temperature value, (ii) the initial internal pressure value, (iii) the updated internal temperature, and (iv) the updated internal pressure value to determine if the cooling loop has a leak; and
in response to determining that the cooling loop has a leak, issuing a warning;
wherein using (i) the initial internal temperature value, (ii) the initial internal pressure value, (iii) the updated internal temperature value, and (iv) the updated internal pressure value, to determine if the cooling loop has a leak includes:
determining whether the initial internal temperature value is about equal to the updated internal temperature value;
in response to determining that the initial internal temperature value is about equal to the updated internal temperature value, determining whether the initial internal pressure value is about equal to the updated internal pressure value; and
in response to determining that the initial internal pressure value is not about equal to the updated internal pressure value, identifying that the cooling loop has a leak.
