DeepCool LS720 (LCS) review - Final words and conclusion

Final words and conclusion

The new DeepCool LS720 turns out to be a superb performer, yet probably will need a little tweaking on the acoustic side if you overclock your CPU a little. The fans are regulated by BIOS PWM and easily can be tweaked, we actually prefer it that way over all the software solutions other competing parties offer. The only way to tackle the nuisance of noise is to lower the fan speed; with a fan speed of 400-800 RPM, the product will become silent. Lowering the RPM, on the other hand, comes at the expense of cooling performance (we're talking 1-2 degrees C here). You'll still be able to keep your temps beautifully under control with a 360mm radiator and close to 350 Watts of cooling capacity even at low RPM, as cooling capacity is not an issue.

Acoustics

The acoustics are acceptable at default, but not 100% silent; if the processor is overclocked, the fans become audible. It's true that they are high static pressure fans that can spin and ramp-up to speeds of up to 3100 RPM, but that's simply too fast for anything that, in my opinion, needs to be silent. The solution is straightforward: lower fan RPM, establish a fan profile in your motherboard BIOS, or have your fans fixed at an RPM level that meets your needs and expectations. You'll have a lot of room to experiment with the cooling performance you get. We were can hear the pump softly if we give it 100% voltage, I'd say feed it half that.

Aesthetics 

The pump may appear big initially, but with the recommended installation method, it can really fit very well on motherboards with DIMM slots that are extremely close to the CPU socket yet offer some clearance around it. The tubing brackets and daisy-chain design are perhaps some of the nicest things you can expect from the LS720 to keep things tidy and organized because they are extremely beneficial features and are not featured on the majority of AIO liquid coolers nowadays.

Installation

Overall it is straightforward to install with the mounting system, prefilled... it's one of the easier and more comfortable kits on the market to use and install. We find the kit to have a bit too many screws and whistles and bells though, which after unpacking can be a little overwhelming. For example; the backplate bracket needs four screws and four washers before you can even insert it. Then on the CPU side, you secure it with two screws but not before you mounted two brackets to the CPU block. It's all no biggy, but we do wonder if that process cannot be simplified. Once you daisy chained all fans, the wiring can become confusing though. Taking your time and reading the manual is our advice.

Pricing

The LCS coolers are reasonably priced, at LS520 - $109 USD | LS720 - $139 USD, and comes with a 5-year warranty and support for anti-leak technology.

Final words

The LS720 receives high marks in the test because of its excellent performance. The RGB lighting is something we like as well. The AiO's cooling performance is excellent; the thing that may be improved is the relatively deficient acoustic performance from the fans. Tweak it a little and you can get a really silent setup here, you certainly have plenty of cooling capacity to play around with. You can apply the latest CPUs, LGA 1700, Intel's most recent socket. Socket AM5 also is already listed to be compatible, so you are pretty future-proof with this kit. We discovered that the entire procedure of installing the LS Series went off without any big snags. The procedure is uncomplicated and easy to follow. We would recommend pre-attaching the cords for daisy chaining before installing the fans/radiator because our initial approach resulted in the connectors on the fans facing the top edge of the case being difficult to access. Pre-attaching cables before putting everything inside the computer case will eliminate the need to re-install. The most confusing part however is cabling itself, take your time there. Other than that the new DeepCool LS720 is a well-designed and capable performer, and it is yet another alternative in a growing industry that is worth investigating further if the price suits your budget. This is a high-performance cooler and comes recommended by Guru3D.
