There are quite a few variations for the SAMA L70, which include the white L70 240WH and L70 360WH, as well as the black L70 240BK and L70 360BK. The one we have is the white L70 360WH. The cooler's design is quite standard with the white ARGB LED fans attached to a white radiator. Two tubes braided with a white fabric run from the radiator to the pump block. The pump block is covered with an acrylic frame and split into two sections. The left contains the SAMA logo printed on a solid white background, while the right contains a square pattern on an infinity mirror. When the LEDs are off, the cooler feels quite flat and dull, but once the LEDs are turned on, the colors add life and vibrancy to the overall feel for an aesthetically pleasing product.
The radiator measures 397mm in length, 120mm in width, and 27mm in height, which are standard dimensions for closed-loop 360mm AIO coolers. The two important design considerations for thermal performance of the radiator are the material used and the effective surface area. The SAMA L70 360WH radiator is made using aluminum, which does not conduct heat as well as materials like copper. However, it has the advantage of being lighter and cheaper. The overall build quality of the SAMA L70 360WH is solid, with no visible advantages or disadvantages compared to other AIO coolers.
The fins on the radiator for the SAMA L70 360WH have a standard layout. The fins are bent in a wavy pattern to maximize the total area available for the air to contact and transfer heat by convection. Radiators are usually split into two, down the long end, to form a sideways "U" path for the liquid. The liquid enters and exits the radiator through two 400mm long FEP, or fluorinated ethylene propylene, tubes. This length should be adequate for most mid-sized cases. The tubes can be bent to form large curves, but it would be difficult to form tight bends as it is quite sturdy due to the material used. SAMA has also included clips already attached to the tubes.
The pump block on the SAMA L70 360WH measures 73mm in length, 73mm in width, and 66mm in height. The contact plate is made of copper and has a smooth finish. The mounting arms are preinstalled onto the sides to simplify the installation process. The pump operates at 2000RPM to 3000RPM through a 12V 4-pin PWM connector. Neither the mean time to failture or noise was listed on the SAMA website.
The SAMA L70 360WH comes with three fans installed on the radiator, which are daisy-chained together through a non-conventional 7-pin connector. The cables coming out of the last fan are the standard 4-pin PWM and 3-pin ARGB connectors. The exact model of the fan cannot be found on SAMA's website, but the specifications are listed on the SAMA L70 page. These are three 120mm fans that can operate at a maximum speed of 2200RPM with a noise level of 28dBA. It produces a maximum airflow of 72.3CFM and air pressure of 2.85mmH₂O. The bearing used is a hydraulic bearing, which tends to have a long life span. However, the approximate mean time to failure is not listed in the specifications. The overall visual design of the fans is simple but clean. The SAMA logo is printed at the center, while each of the side walls on the frame has a singular "V" shaped engraving. As for the ARGB LEDs on the fans, the LEDs shine brightly with a great amount of vibrancy to the colors.
