Equipped with only a single 120mm fan, we weren't expecting a lot from the Core G21 TG in terms of thermal performance. The fan also proved to be quite slow spinning even at full speed (this at least means it's rather quiet), and even with the ventilated front and roof, it only managed a relatively warm delta T of 57°C with our test hardware. Nonetheless, we're confident this could easily be improved upon given the expansion options – what's important to note at this price is that it does an adequate job even with overclocked hardware.
Things were similar on the GPU front, with the delta T of 53°C again placing it in the lower half of the graphs. Again, though, there's heaps of room to use a GPU with a better cooler than ours, and the front and lower intake mounts can easily be used to boost airflow.
