Testing:

I will be taking note of the HDD, CPU, GPU, and ambient case temps under both idle and load conditions. The cases I will be testing against each other will be the Guardian 921 mid tower, Thermaltake M9 Mid tower, and the NZXT Zero 2 Full Tower Case. The room temps will be regulated at 28 degrees in order to provide a fair testing grounds. Let's light these bad boys up and see which one blows (the best). In almost any other competition this would be a bad thing but not for high flow cases like these let's checkem out:

The Zero 2 did beat the Guardian in a number of the tests but what you need to remember is that the Zero 2 is a much larger case and has two massive exhaust fans and a lot more area for hot air to be dispersed. Let’s see the final thoughts:
