The Enermax ETS-F40-FS ARGB is not a high-end air cooler or even a performance-focused one. Instead, it offers decent performance with a focus on visual appeal for mainstream to mid-range systems. It even avoids being overly loud due to the fan's relatively low maximum RPM and attractive minimum RPM, as the cooler has an overall RPM range of 300–1200. This keeps noise levels in check. Compared to similarly priced coolers that brute force it with high RPM fans, performance doesn't hold up. The only place the cooler will really shine is in lower TDP scenarios, such as non-K Intel SKUs and stock mid-range Ryzen CPUs.

There is also that the ETS-F40-FS ARGB failed to keep either processor in check in our overclocking tests, outside of idle, be it the Intel i9-10900K or AMD Ryzen 9 3900X. Those looking to push their hardware will want to look at performance-focused alternatives that cost the same or less when it comes to keeping the processor cool. As you may have guessed, the Enermax offering is rather expensive for the performance on offer, especially considering it only ties the ID-Cooling SE-914-XT, a 92 mm tower cooler at roughly half the price. That said, given the cooler's tasteful all-white or all-black design depending on the version and ARGB lighting, it obviously is tailored around those wanting a visually appealing cooler, which is also up for debate depending on personal taste.

Keeping in mind that the cooler excels in a stock or low TDP situations, it's not all bad, but the limited one-year warranty and lackluster mounting hardware for AMD platforms hurt the cooler's appeal. That said, the mounting hardware issue is extremely common on AMD platforms, one I see with many manufacturers, not just Enermax. The issue boils down to the stock backplate, which is fine on its own. However, trying to hold the backplate in place along with plastic spacers and mounting arms while screwing it all together is and always will be a pain. A better design is possible and something all vendors should be looking into considering AMD's continued rise in popularity, especially in the enthusiast market. As for the Intel mainstream sockets, the mounting system was much easier to work with overall.

Overall, the bottom line is that the Enermax ETS-F40-FS ARGB is a cooler that looks pretty, and for the entry to mid-range, CPUs will perform just fine. Still, performance-wise, it falls behind its peers and instead becomes an option for those who care more about aesthetics than performance, especially on higher-core-count processors.
