The latest cooler on our test bench is the Sigma L36 Pro, a high-end AIO with a 3.5-inch display from relative cooling newcomer Ocypus. This manufacturer is known for quirky design choices that help set it apart from its many competitors. I found the company\u2019s Iota C70 computer case<\/u><\/a> and A62 digital air cooler<\/u><\/a> especially interesting products when I tested them last year. <\/p>\n

Like many other AIOs we\u2019ve reviewed lately, the Sigma L36 Pro features a display \u2013 a large 3.5-inch detachable screen in this case, capable of displaying performance metrics and animated images and video. <\/p>\n

Screen aside, the technical specifications of the product are impressive. The static pressure exerted by the fans is nearly twice as strong as many competitors \u2013 rated for up to 5.8 mmH20. But even more impressive than this is the price of the liquid cooler: Despite having a relatively large display and extremely powerful fans, you can find this cooler selling for $135 or less.<\/p>\n

Let’s take a look at the specifications and features of this eye-catching AIO, then we\u2019ll go over thermal and noise benchmarks so you can decide if the Ocypus Sigma L36 Pro deserves to make our list of the best CPU coolers<\/u><\/a>.<\/p>\n

Features of Ocypus Sigma L36 Pro<\/h2>\n

\u25b6\ufe0f Detachable 3.5-inch 640×480 resolution IPS display<\/strong><\/p>\n

It seems like the biggest trend in liquid cooling recently is AIOs with fancy displays on top of the CPU block, and Ocypus rides this trend, including a 3.5-inch IPS screen here that some users might find reminiscent of older PCs due to it\u2019s VGA (640×480) resolution and 4:3 aspect ratio.<\/p>\n

\n

Many AIOs have the screen built into the CPU block, like Hyte\u2019s THICC Q60<\/u><\/a>. Other manufacturers offer the display and CPU block as separate components, and that\u2019s how the Ocypus Sigma L36 Pro is designed. <\/p>\n

When a display connects to the PC, but isn\u2019t actually built into the CPU block, this opens up customization options that you might not think of normally. As you can see in the photograph above, I\u2019ve got the display set up on a stool next to my computer desk, instead of inside my case. You\u2019ll have to obtain a 9-pin header to USB-A (or C) adapter to use the device externally, but these can usually be found for less than $10. <\/p>\n

To control and customize the display, you\u2019ll need to download the simply named Ocypus Display software. It\u2019s a surprisingly small download size of only 184 megabytes, and uses 493 MB when installed \u2013 and about the same amount of RAM when active.<\/p>\n

Multiple preset themes are available, but only three are installed by default. <\/p>\n

If you click the cloud icon shown in the picture above, a link to Ocypus’ \u201cDownload Center\u201d<\/u><\/a> is opened in your default browser, which offers more options. <\/p>\n

The software is extremely simple to use and easy to create your own customized theme with. In the example above, I uploaded an animated GIF file of a happy puppy and set the display to monitor CPU temperature, power consumption, and fan speeds metrics through text labels. I\u2019ve also set up monitoring of CPU utilization, both with a text label showing the current status and a line graph showing the changes in CPU utilization over time. <\/p>\n

\u25b6\ufe0f RAM Clearance<\/strong><\/p>\n

As with most liquid coolers, the design of this AIO is such that the CPU block as such that it doesn\u2019t overhang or interfere with the DIMM slots in any manner, ensuring that all sticks of compatible RAM, no matter how tall, will fit with this cooler.<\/p>\n

\u25b6\ufe0f Thick CPU cold plate<\/strong><\/p>\n

This AIO is designed for normal PC platforms like Intel\u2019s Arrow Lake and LGA1851 socket or AMD\u2019s Ryzen X3D CPUs and the AM5 socket, but you might wonder if it supports server products when you see the size of the coldplate \u2013 it has a larger surface area and greater thickness than most liquid coolers designed for consumer PCs. <\/p>\n

\u25b6\ufe0f 120mm fans<\/strong><\/p>\n

There\u2019s more to a cooler than just the radiator and liquid pump. The included fans have a direct impact on aesthetics, noise levels, and overall thermal performance. Conveniently, the fans here arrive pre-installed, saving a few moments of time when you put things together. The fans included in this model are white, but this cooler is also available with black fans. <\/p>\n

These fans seem to be overbuilt, more powerful than the rest of the AIO can properly take advantage of. They are rated for an unusually high 5.8 MMH20 of static pressure and 90 CFM at full speed.<\/p>\n

\u25b6\ufe0f Packaging<\/strong><\/p>\n

The outer packaging is a bit flashy, at least in comparison to your normal AIO box. It features a rendering of the cooler against a black background with streaks of purple hues \u2013 logos on all sides of the box for full marketing impact. <\/p>\n

The inner packaging is just as fresh as the outside, with each component of the cooling system well protected from the chaos that shipping can bring by using a combination of soft covers and individual cardboard walls for each component.<\/p>\n
