With their first foray into liquid cooling, Aerocool has gone all out with the P7-L240. It offers tremendous performance that is on par with the Alphacool Eisbaer 240 while being quieter. That said, it doesn't dominate the performance chart, but is still on the high-end with only the EKWB Predator 280 truly dominating it with an 8% lead. To put that into perspective: in the AIDA64 OC FPU test, the P7-L240 kept the test system's 6700k at 77°C. The Alphacool Eisbear 240 also kept the CPU at 77°C, while the Noctua NH-D15 hit 75°C, and the EKWB Predator 280 was the best performer at 72°C.

In terms of noise output, the P7-L240 hit 43 dBA at 100% PWM. That is 3 dBA quieter than the Alphacool and on par with the Noctua NH-D15. As such, overall performance is solid, and other than the custom-expandable all-in-one liquid coolers, the Aerocool P7-L240 is the quietest closed-loop cooler I have tested when delivering its maximum-possible performance. As such, this particular unit offers a nice blend of performance and low noise output, while also offering additional features.

In general, the unit is well built and very easy to install, which, when paired with its unique pump design kitted out with RGB LEDs, means that you end up with an attractive offering that can be tailored to match just about any build's theme. AMD Ryzen users will also be happy to know that the unit supports socket AM4 out of the box. Overall, there is a lot to like about the P7-L240, especially if you are a fan of RGB LEDs, but more on that in a moment.

A few issues are apparent. First, the unit is expensive. If you don't need RGB LED compatibility or prefer something a bit more subdued, better options are available. I myself feel RGB LEDs are the current fad to which all manufacturers are flocking. It will be around awhile, until the next big thing comes along, at which point it will be forgotten. Regardless, I have no issues with the RGB LEDs, but the problem is their proper support. The unit requires an expensive hub (P7-H1) or a motherboard with RGB functionality to utilize that feature. If your motherboard doesn't support it, you are looking at spending another $25 on top of the cooler's price just to use that feature. The hub itself is quite handy and does more than just allow for RGB functionality since it can power fans as well. Still, it adds to the cost of ownership, and its design has to be taken into account when used in a system build.

My only other thoughts on the P7-L240 stem from the RGB-lighting standpoint. It is a cool feature for those who want it, and Aerocool has made sure it can be turned off easily enough. The optional P7-H1 Hub offers the additional functionality of a fan hub and can be bought in a kit to add extra fans with the same RGB LED support. However, the cost of implementation means the P7-L240 is not going to appeal to users looking for a more subdued appearance when it comes to an AIO liquid cooler. As such, the P7-L240 is targeted at a specific market. However, considering their cases, fans, power supplies, and now coolers all support the RGB LED craze, Aerocool has an entire product range with that functionality in mind. This is something no other vendor is currently offering. So if you love the look of LED lighting in your PC, Aerocool definitely has you covered. If you like a more subdued rig, you may want to look elsewhere.

If you are in the market for an all-in-one liquid CPU cooler that not only performs well, but is also quiet while delivering a fully featured RGB LED experience, the Aerocool P7-L240 might just be what you are looking for.
