Testing Results, Low Fan Speed
Using a PWM voltage regulator, we reduced the speed of the fans manually down to their minimum rated speed, which is ≈500 RPM. The pump was also connected on the same power source, functioning properly at this low speed setting.
The thermal performance of the DEEPCOOL Captain EX 240 RGB with its pump and fans driven down to their minimum speed is mediocre, with an average thermal resistance of 0.1126 °C/W. Many similarly sized kits that we have previously tested were below 0.1 °C/W, albeit most are significantly louder implementations. As always, thermal performance only tells half the story when we are testing coolers, we need to have a look at the noise figures before jumping to conclusions.
| Core Temperature, Constant Thermal Load (Low Fan Speed) |
The sound pressure reading that the Captain EX 240 RGB gives under these operating conditions is only 32.4 dB(A), one of the lowest that we have ever seen. One needs to place an ear literally next to the radiator in order to discern the airflow noise, and the pump is entirely silent. Assuming a typical setup where the cooler will be installed inside a computer case sitting on or under a desk, it would be essentially impossible to discern any noise coming from the Captain EX 240 RGB while it operates under these speed settings. Most mechanical hard disk drives are louder.

It would be nice to see some common heatsinks within the same price bracket included in the comparison charts, even if it's only a handful. They're direct competition after all.HollyDOL - Thursday, December 14, 2017 - link
I have to agree, otherwise the results are quite relative.Put in at least a couple for reference (like Intel highend stock, AMD highend stock, and some elite one like Noctua NH-D15), it would make the info much more worthwhile for general public

not like stock coolers could hope to do anything except bbq with 340W load ofc...Dr. Swag - Thursday, December 14, 2017 - link
Awesome! A decent alternative to the S24 when it comes to quiet AIOs that also has rgb!sweetca - Thursday, December 14, 2017 - link

Sometimes I wonder... if some of these reviews are sponsored (either by one manufacturer or a group of manufacturers, to boost brand exposure and potentially sales)... and not necessarily direct monetary sponsorship. I also wonder... if the reason Anandtech didn't include a high-end air cooler (e.g., NH-D15)... is because it would make a strong case for the AIO solutions making a very poor value proposition... especially when considering noise/cooling ratios... and, in turn, rendering this entire review pointless.E.Fyll - Thursday, December 14, 2017 - link
Actually, the answer to your question is far less complicated than that. We only compare air coolers to air coolers and liquid coolers to liquid coolers because each represents a specific type of product. It's an "apples to apples" kind of thing. I also personally do not believe that these two actually compete with each other. Users are much more likely to go for an AIO cooler because they want easier access to their system, or because they just don't like a 2kg piece of metal hanging off their motherboard, or just because it "looks cool", than for the performance. If acceptable performance is all that a user needs, an average air cooler can do the job just fine, they do not even need a NH-D15 to begin with.Besides that, the magic of having and using professional equipment like ours is that everything is both repetitive and comparable. They were all tested on the exact same device and everything is in our methodology page that can be found in every cooler review. Long story short, you can easily go to our review of the NH-D15 cooler (or any cooler that you'd like to compare, regardless of its type and platform) and just compare any of its performance figures to any AIO cooler that you want to, taking into account your personal requirements too.

Sorry no.. it is green apples to red apples in most buyers considerations.. or dreams, and they really need to know what they are paying extra in case their dream comes true.rtfmx9 - Thursday, December 14, 2017 - link
I think that "apples to apples" does not hold here. After all, both liquid and air coolers serve the same purpose. It would be nice to be able to compare them without having to do research through Anandtech's archives. Is it possible that once comparison is made obvious liquid coolers don't make sense from the cost/performance point of view? I don't know since review does not try to inform me from that perspective. My guess is that there are many people who would like to inform themselves of whether upgrade to a liquid cooler would make sense or not but to do that you recommend that they dig though the past reviews instead of you offering that information in your review. All for the sake of keeping apples and oranges separated. I don't buy that reasoning.
