As mentioned earlier, the current range of the Qube brand includes cases, coolers and monitors. And if we had a chance to get acquainted with one of their computer chassis earlier, now it is the turn of cooling systems. The cooler we are talking about now is called QB-OL2000GT, and it is an OEM version of Jonsbo CR-2000GT. You can learn about how this system works and what it is capable of from this review.

Packing and scope of delivery
The cooler is packaged in a decent-looking box with colorful glossy printing on the sides. Here you can look at the appearance of the product and learn about its main technical characteristics. Damage protection is provided by a pair of polyurethane foam dampers. Accessories are folded into a couple of small boxes and packaged in separate packages.
We found the following parts in the cooler package:
- universal metal reinforcement plate for Intel and AMD sockets;
- two mounting feet for Intel LGA 775, 115x/1200/1366/2066 sockets;
- four round fixing gaskets for studs;
- four screw studs;
- two mounting feet for sockets AM3 and AM4;
- four metal screw racks for Intel LGA 2066;
- four knurled nuts for fixing the mounting feet;
- four plastic spacers;
- double-sided adhesive tape for the controller;
- ARGB backlight controller with cap.
Installation instructions can be downloaded using the QR code on the package. The fact that the device was released with the direct participation of Jonsbo is hinted at by the packaging of the ARGB controller and the inscription on the tube of thermal paste.
Two splitters are attached to the cooler — for lighting and powering the fans. The first is an adapter from three two-pin connectors to two outputs of the + 5VDG type (“father” and “mother”). It can be connected directly to the motherboard if it supports backlight control. The second splitter is a standard Y-wire from one PWM fan connector to four pins to two separate ones. In case there is no extra CPU FAN output on the board.
Qube QB-OL2000GT is a rather compact tower cooler with two separate fin sections. In the front projection, the radiator is completely hidden behind a fan with translucent blades. The width here is 120 mm (not counting the slightly protruding mounting brackets). The height is declared at 159 mm, but in fact it does not exceed 156 mm.
The width of the cooler in profile with the front fan installed is 134 mm. Fan mounting brackets allow you to adjust its landing height up to 22 mm upwards relative to the optimal position, when the fans do not look beyond the top radiator linings. Useful if there is a headroom in the case and the RAM will be higher than expected.
At this angle, the user will see this cooler in their case most of the time. It is worth noting that the diagonal stripes and the three-beam symbol on the upper overlays are ARGB-backlit.
The cooler comes with two 120mm fans of the same configuration. The only difference between them is that the middle propeller is not illuminated (and this is logical, no one will see it there anyway), and the front propeller is equipped with ARGB LEDs located around the engine in the center. Accordingly, the impeller is translucent in front, and black in the middle. Otherwise, everything is similar — nine slightly curved blades, a hydraulic bearing, a frame with rubber gaskets on the side of the mounting brackets and a declared speed range from 700 to 1500 rpm, adjustable using PWM. In fact, we got from 900 to 1750 rpm, which is slightly higher than the permissible error of 10%. Fortunately, the minimum speed coincides with the conditionally silent operation at a level of 40 dB (A), and the maximum leads to an increase in noise up to 59 dB (A), which is already quite loud. Parasitic noises and vibrations during fan operation are present, but they cannot be called critical. The four-pin power connector is very short and obviously will not reach anywhere without a splitter. The backlight output for two pins is slightly longer, but it is also not intended for mounting without an adapter.
The backlight can be connected directly to the motherboard through a complete splitter from three connectors to two pins to two standard + 5VDG (such as «father» and «mother»), attach additional elements to it, or plug it into the ARGB controller, which is also included in the kit . The controller is powered by a SATA Power connector and is able to sequentially switch colors and backlight effects by pressing a key on its body. It is interesting that near the power output it is possible to connect to two contacts, for example, the Reset cable from the case and switch the backlight with the corresponding button on the outside. A simple and elegant solution to problems for owners of budget motherboards and chassis.
The Qube QB-OL2000GT heatsink is a standard dual-tower design where two separate symmetrical arrays of fins are connected by copper heatpipes. On the edges of the ribs there is a cut in the form of teeth, and the lower part of the plates is slightly trimmed to create less interference with the high levels of RAM. The ends of the heat pipes are hidden under plastic overlays in the built-in ARGB backlight. The backlight power cords are laid in special recesses on the front of the cooling sections.
The body of the radiator consists of six copper 6mm heat pipes and 40 fins in each of the two sections, located with a gap of 2.2mm. The total heat dissipation area is 7680 cm², which is not bad on average, but not enough for two-tower models. The heat pipes are U-shaped, three in each direction. If you look in profile, then in the body of the radiator they are evenly spaced in a row.
On the sides, the radiator plates are bent by two strips at 90 degrees, which strengthens the radiator as a whole and prevents the fins from sticking to each other.
The upper overlays are made of black (stylized with a metal texture) and translucent plastic. All transparent inserts are highlighted with any rainbow colors.
To fix the radiator on the central pressure plate, two spring-loaded screws with cutouts in caps for a Phillips screwdriver are installed on the sides.
The heat pipes are tightly pressed into the pressure plate.
The tubes are located end-to-end and the base of direct contact turned out to be quite even and without gaps. However, in the center there is a «stiffening rib» 2 mm wide. Probably, it was impossible to do it differently due to technological nuances.
Let’s move on to installing and testing the cooler.
