Overview of the CPU cooler MSI Core Frozr L

Equipment
The MSI Core Frozr L package, apart from a radiator and a fan, includes the following:
- • Installation guide;
- • Syringe with thermal interface;
- • Black upper cooler pad to change;
- • Two additional fan brackets;
- • Four rubber damper for the second fan;
- • Universal reinforcement plate;
- • Mounting bracket for the cooler;
- • Universal mounting frame for all socket types;
- • Four threaded metal stands with rubber pads;
- • Four long screws;
- • Four threaded stands with thumbscrews for the Intel LGA2011 socket;
- • Four short screws;
- • Four large plastic pads;
- • Four small plastic pads;
- • Two fixing screws for the Intel sockets;
- • Two mounting screws for the AMD sockets.

Specifications
The MSI Core Frozr L outside is pretty standard. It is made according to the classic U-shaped heatpipes’ allocation scheme and has average dimensions. Radiator symmetry axis is shifted aside in order to eliminate a possible conflict with the PCI-E socket when mounted on small-sized motherboards.

The fan is secured to the radiator using wire clips of quite a specific form. In size, the fan never exceeds the radiator body.
The top panel is has an attractive strip of gray color (it can be changed to black) with the illuminated Gaming-series logo – a dragon.

The fan has standard dimensions: 120x120x25 mm. Its corners have built-in red rubber vibration dampers. 14 of the impeller blades have an unusual shape and feature a sharp bend in the profile middle which should create a better airflow at a lower noise level. The rotor center is also pasted with the dragon-shaped logo. The power cord has a four-pin connector, short length and has no braid.
The propeller manufacturer is Power Logic. The use of a hydraulic type bearing (HDB) is stated, which should not be confused with a hydrodynamic (FDB) one. The latter may excel the first one in both quality and the duration of work to failure. However, it is still much better than the conventional sliding sleeve or noisy ball bearings. The impeller operating speed ranges from 500 to 1800 rev/min. It is relatively quiet on the segment from the start to 800 rev/min and 40 dB (A). When ranged 900-1,000 rev/min the blades’ noise becomes audible. Up to 1,300 rev/min the noise level can be described as average, and in the range from 1,400 to 1,800 rev/min the noise becomes strong and irritating. Fan speed is controlled by the PWM.
A splitter needed to connect a glowing MSI logo on the top panel of the cooler is supplied with the fan. And if the propeller power can be removed with no problems, then disconnecting the logo power supply without cable damage can be problematic. Unfortunately, a splitter to enable the second fan is not supplied.

The heatpipes are separated by staggered sides which ensure a good heat distribution at optimal air flow permeability. However, the ribs are located sufficiently close, with a total gap of just 1.8 mm, which deteriorates the radiator blowing at the fan low speed. The total heat dissipation is about 8,000 cm², and it is quite a good indicator for middle-class tower coolers.
The total height of the cooler, even with the plastic pad on the top does not exceed 155 mm, which means that it is definitely compatible in height with the vast majority of standard and even budget cases, in addition, there is enough space to connect any motherboard sockets.
Even if the fan covers the RAM slots on any small-sized motherboard, it will not interfere with the standard height sticks.
Cooler logo backlight on the cooler undoubtedly pleases: it looks good and does not blind eyes.

Conclusions
MSI Core Frozr L is a debut cooler from the reputable manufacturer of computer components. Though being the very first one, the model is very good. Of the merits the following should be definitely noted:

• attractive looks and interesting backlighting
• wide compatibility with different processor sockets types (including the pending AM4 one)
• small size allowing to place it even in budget-class cases
• adequate cooling efficiency for up-to-date processors.
The only drawback is a reduction in the cooling capacity at low fan speeds, caused probably by the radiator design features.
Core Frozr L is a good CPU cooler, which will please all the MSI fans with an opportunity to assemble the system of one’s own using the components designed in the Gaming-series unified style.
