All temperature charts are sorted with lowest load temperatures at the top.
Starting at our stock 4GHz, unfortunately the GAMMAXX L240 is nestled in with a number of air coolers toward the bottom of our rankings. It still sits quite close to both the Gamer Storm Captain 240 Pro and Captain 240 RGB EX, but its closest competitor in terms of price – the £60 SilverStone TD02-RGB – does perform a little better at this frequency.
At 4.5GHz, the L240’s fans basically ramped all the way up to full speed and stayed there, making it suddenly much more audible. This did lead to some more impressive temperatures, though, and sees the GAMMAXX L240 actually overtake the TD02-RGB.
With our 5GHz testing, there wasn’t any real audible difference in fan noise moving up from 4.5GHz, with the fans spinning at essentially the same speed. Even at this higher overclock, the GAMMAXX L240 still sat in a similar position, just above the TD02-RGB.
As we mentioned, the L240 is fairly loud – though not quite as loud as the TD02-RGB. It wouldn’t be for anyone looking for a dead-silent CPU cooler, but at this price you expect some sacrifices – and it is still quieter than the TD02-RGB, despite outperforming it at 4.5GHz and 5GHz.
