Results – 36 dBA
Today’s article serves as an introduction of a new player on our market, besides the usual review. This is Valkyrie, a company that offers mainly liquid AIO coolers, although you can also find one air cooler in their offer. The focus of today’s article, however, is the Dragonfang 360, which is a liquid AIO cooler that promises solid efficiency at a reasonable price, which of course I intend to rigorously test on my test rig.

In this category you will no longer find load test results at 210 W. The reason is the impossibility of achieving such low noise at very high load with any cooler I have had the opportunity to test, even with the best 360mm AIOs. However, the results at 125W load understandably remain, and if no value is listed for the cooler, it means that it could not be adjusted to such a low noise level.

Great analysis as usual guys
Question, do you take the pump noise levels into account as well?
Any way to test pump noise reliability (vibration or rattling during idle, like the typical zzzzzzz slightly audible if close to the case).
Im thinking about the LT720 DeepCool, but my current LE720 DeepCool produces a slight buzz noise that I want gone.
Thanks!
Hello and thanks for your comment.
Yes, I always take pump noise into consideration as it’s part of all those noise normalized testing. And it’s always an issue with AIO – they can never be whisper silent as air coolers due to pump noise. I have fully fledged custom liquid cooling loop in my PC and even it is not completely silent, my DDC at 20% (lowest possible setting) is still slightly audible.
LT720 is a great cooler, I used it as an interim cooler while waiting on some cooling parts after periodal upgrade of hardware. But you will still hear the pump, no matter what. You want complete silence? Go passive/semi-passive, no other way around it (which sucks a little for me as well, I’d love dead silent system, but I also need computing power which means higher power output and thus more cooling capacity which comes along with some noise as well).
An isolated evaluation of the pump would be nice to see, even if it’s only frequency analysis.
The question is how relevant in terms of accuracy it would be. I suppose that the technical level of deaeration, which is significantly reflected in the noise level of the pump, can be different within the same model. Especially for cheaper liquid coolers. I don’t think that this is something that manufacturers are concerned with in terms of quality standards. Of course, then it is possible to take more samples for analysis, but as you can see, we have different time frames for different tests. We can’t devote as much space to CPU cooler tests as we can to fan tests, for example.
