CONCLUSION

   I have to admit that the NITRO+ S240-A AIO by SAPPHIRE confused me a bit since nowhere does it mention the two clear plastic covers mounted on the radiator. On top of that even though the picture on the box clearly shows the fans on the exterior side of the radiator marketing pictures show the fans on the interior side. Because of that I ended up testing it with the fans on both areas (intake/exhaust - just in case these weren't covers in the end) and as you can clearly see from my charts there were differences both in terms of cooling efficiency and noise levels. Now in terms of cooling efficiency it didn’t matter much where I placed the fans, where it did matter was in terms of noise so again, I don’t see any obvious pros by having these clear plastic pieces on the radiator. As for looks well my motherboard doesn’t support RGB/ARGB lighting and none of the adapters I have here seemed to work but it’s clear from all the pictures that SAPPHIRE did a very good job in that area. The variable pump is also a good touch even though I’d rather they used a manual switch on the pump like for example Fractal with some of their past models (faster and easier, at least for me).

   SAPPHIRE is behind some of the best AMD graphics cards to date so obviously I had high expectations from their NITRO+ S240-A AIO liquid CPU cooler. Unfortunately, with a current price tag set at 163.57Euros inside the EU (Amazon.de) I can’t say it lived up to them, at least not the 240mm model (the 360mm I didn’t have the chance to test). Still even though noise levels are quite higher than other AIO models (especially with the funs on the outside) and it’s somewhat pricy the NITRO+ S240-A does deliver good cooling efficiency while at the same time looking great and for that I do recommend checking it out.
