Now, let’s compare the products with each other and with an open testbed.
The Lian-Li looks better than the others in idle mode. The Corsair at the minimum fan speed is the worst case here due to the densely populated rack with HDDs that call for more cooling.
The standings do not change when there is a high load on the disk subsystem.
When there is a high CPU load, the Cooler Master Cosmos 1000 is the loser. It is inferior to its opponents in terms of CPU, mainboard and graphics card temperatures.
The three cases are similar when it comes to high gaming load. The Lian-Li looks somewhat better than the others, but its advantage is not considerable. Every case passes this test easily as all of them are obviously meant for hotter configurations.
