Performance Analysis

We still have limited results from sub-£40 coolers with the closest option being Cooler Master's £60 MasterAir MA410M. However, despite the latter using two 120mm fans, it was only 1°C cooler with a delta T of 52°C in our LGA1151 system dealing with our overclocked Core i5-7600K. This equated to a Core Temp reading of just over 80°C, which isn't actually too shabby for a fully-loaded, overclocked Intel quad-core running at 4.8GHz across all cores.

As expected, the Freezer 33 eSports One isn't a good option for an overclocked HEDT CPU and it quickly reached its limit dealing with our overclocked Core i9-7980XE. This isn't surprising, though, given the TDP recommendation, and if we were dealing with a stock-speed Core i9-7900X, or similar, things would probably be perfectly reasonable in terms of temperatures. 

Finally, there's our AM4 test system, which uses a Ryzen 7 1800X. Here the Freezer 33 eSports One was just one degree behind the MasterAir MA410M with a delta T of 60°C, which bettered several all-in-one liquid coolers on their silent profile settings. Again, you'll see much better performance by opting for an all-in-one liquid cooler, but even the Be Quiet! Dark Rock 4 could only manage a delta T 2°C lower. Noise-wise, the Freezer 33 eSports One did spin up to audible levels at maximum speed, but it was simply airflow noise and nothing whiny - we'd be happy sitting next to it during a video-rendering session.


Our graphs lean heavily in favour of AIO liquid coolers at the moment as they're the ones occupying most results, but while they obviously outperform the Freezer 33 eSports One in all our test systems, it's only when it comes to dealing with overclocked HEDT CPUs that the performance is unacceptable. An overclocked CPU temperature of around 80°C is perfectly fine, especially for a £30 cooler, and that's full load, too - it will be much cooler than this in games and less-demanding tasks. 

As a result, it gets a thumbs-up for LGA115X systems, while for AM4, it's perhaps a little better suited to AMD's quad-core and hexa-core Ryzen CPUs if you want to dabble in overclocking, seeing as our overclocked Ryzen 7 1800X got fairly toasty. Again, though, at stock speed or outside 100 per cent load levels it will be fine, so if you're after a cooler costing around £30 for your Intel or AMD mainstream system, we can definitely recommend the Freezer 33 eSports One.
