What’s new with DeepCool LE AIOs? Quieter pumps and lower prices

DeepCool LE720 and LE520

At first glance, DeepCool’s latest liquid coolers don’t seem to be any different from the older LT SE models, but there is one significant difference, and that’s in the pump speed. The latter is slower, quieter and yet should not cause a significant drop in cooling performance. And then there’s the attractive price, a model with a 360 mm radiator fits into a hundred euros.

In the last period DeepCool has released several AIO coolers, but it is only now that it comes with a lower class at an affordable price for this type of cooler. As usual, the LE (Lite Edition?) series includes a larger (LE720) and a smaller (LE520) and model with 120 mm fans.

These coolers seem to look exactly like the more expensive DeepCool LS SE coolers, which are more expensive. The water block cover is indeed very similar, but if you focus on the details, you’ll find slightly different dimensions (91 × 80 × 52 mm). They are adapted to a different pump with a lower speed. Instead of the latest 4th generation DeepCool pump, an older 2nd generation model is used. The latter (at 2550 rpm) is 550 rpm slower at top speed and, according to the specifications, 1.2 dBA quieter. But it also has a lower flow rate (we don’t know by how much) and the cooling performance of the liquid cooler will probably be lower than the faster pump variants. What the difference will be in comparable noise levels we won’t find out now, but we can assume that manually slowing down the pump will allow the LE coolers to get to a lower minimum noise level.

The fans used are the same as those used on the DeepCool LS SE – the lighted FC120, which we tested in the slightly slower variant. Models on the LE coolers have a more powerful motor with 750 rpm higher top speed (2550 rpm). Fan speed is above standard, higher than most competing solutions, which can possibly outperform the LE520 and LE720 coolers with higher airflow, albeit at the cost of higher noise levels.

However, the minimum speed should be the same as for fans sold separately – 500 rpm. So most likely it will be possible to slow the fans down to very quiet operation. At lower speeds, even the rumbling sound frequencies that accompany this fan due to the more flexible blades with some vibration will subside.

The radiators are fairly “standard”, both in terms of dimensions (282 × 120 × 27 mm and 402 × 120 × 27 mm) with 27-millimeter thickness as well as fin density (FPI) and aluminium design. Meanwhile, the tubes are 410 mm long and are traditionally fixed to the block via swivel fittings for better adjustment.

All current AMD (AM5 and AM4) and Intel (LGA 1700, 1200 and 115x) platforms for mainstream processors are supported. TDP of the coolers is listed at 220 (LE520) and 240 W (LE720). They are due to start appearing in stores from mid-July 2023. The manufacturer’s suggested retail price is 100 EUR for the 360mm variant and 80 EUR for the 240mm one.
