Temperatures
All temperature charts are sorted with lowest load temperatures at the top.
Testing results look pretty good with the Castle 240 RGB sitting above the Gamer Storm Captain 240 RGB EX, but just below the Arctic Liquid Freezer 240 and the Cryorig A80 which is unsurprising as the A80 has a slightly larger 280mm radiator.
When overclocked, it is nice to see a temperature drop from the older Gamer Storm Captain 240 RGB EX, so not only, in my opinion, a better-looking option but also better performing than the older Captain 240 RGB.
The Castle 240 did turn out to be slightly louder than the Captain 240, but only by one decibel or so, but during our testing the PWM fan controller included with the Castle 240 wasn’t put to use so there is the potential to set up a more silence-optimised fan profile through software, if this is your preference.
