Thermalright’s SI-100 is a 120mm class low profile CPU cooler, similar to the C14S. The SI-100 is 100mm in height vs. NH-C14S at 115mm.
SPECIFICATIONS
| MODEL | SI-100 |
| DIMENSIONS | L: 120 x W: 108 x H: 99.8mm (including 25mm thick fan) |
| MATERIALS | 6x 6mm copper heat-pipes, copper base (nickel coated), aluminium cooling fins |

TEST SYSTEM
Testing is carried out on BC1 Mini v2 (Open Testbench), using the following hardware in 20°C ambient room temperature.
| CASE | BC1 Mini v2 (Open Testbench) |
| MOTHERBOARD | Rog Strix B650E-I Gaming WiFi (paid link) |

| PSU | Extreme 850R (paid link) |
| RAM | 32GB Gskill DDR5, 6000MHz, CL30 (paid link) |
NOISE
At 70% fan speed, the SI-100’s included 120x25mm fan outputs around 35dBA noise at distance 50cm. It’s not as objectively quiet as an Noctua’s NF-A12x25 for instance, but still fairly quiet.
THERMAL BENCHMARKS
We use Cinebench R23 multicore (stability test), for CPU thermal testing. This provides worse case scenario for a given CPU.
CONCLUSIONS
Thermalright’s SI-100 is excellent performer, even outpacing the larger, heavier Noctua NH-C14S. It offers reasonable motherboard and RAM compatibility and is aggressively priced relatively to thermal performance.
