The IS-55 is more recent low profile cooler from IDCOOLING. The cooler is 55mm tall and can be mounted in either orientation without affecting performance according to the manufacturer. The IS-55 comes in either white or black, and also RGB variants.
|DIMENSIONS||L: 120 x W: 120 x H: 55mm (including 15mm thick fan)|
|MATERIALS||5x 6mm copper heat-pipes, copper base (nickel plated), aluminium cooling fins|
|FANS||1x 120x15mm (2000RPM)|
Testing is carried out on BC1 Mini v2 (open testbench), using the following hardware, in 20°C ambient room temperature. We noise normalised the cooler fan speed to 35dBA at distance of 50cm. This helps eliminate brute force cooling from higher RPM fans.

We use Cinebench R23 multicore (stability test), for period of 30 minutes. This provides worse case scenario for a given CPU. CPU coolers are tested across range of CPU’s for data validation and to reduce risk of errors in testing. This also helps account for variables between CPU platforms.
The IS-55 has been designed with focus on LGA1700 & AM5. It has good build quality and a simple; effective mounting solution. In pursuit of performance, the IS-55 has some compatibility issues with some motherboards and is also limited to 33mm RAM clearance, this rules out mounting the cooler over the I/O shroud on majority of LGA1700 & AM5 motherboards.
