IceRiver KS5L (9 TH/s)

Imagine I hand you the IceRiver KS5L and, in doing so, make you my accomplice: this desktop ASIC miner, built for Kaspa's KHeavyHash, arrives with an official rating of 9 TH/s yet can push toward 12 TH/s under optimal conditions while drawing 3400 W, an architecture tuned to steer power where it matters and to trim waste so efficiency sits near 283 J/TH - you feel its intent; compact at 370 x 195 x 290 mm and weighing 15 kg, it slips into racks and corners alike, its chassis a promise of quiet engineering that houses an efficient air-cooling system with four 120 x 120 x 38 mm fans, a smart cooling design that dissipates heat methodically to preserve stability and extend lifespan, rated to operate between 0 and 35°C and 10%–90% humidity so it survives diverse environments without asking for special favors; set up is simple and intimate via an intuitive web interface that hands you remote management, monitoring and firmware updates - you will watch temperatures, tweak settings, push hashes and sleep knowing the machine reports back - and because you are now complicit, you can use a profit calculator to estimate daily, monthly and yearly returns while factoring in electricity costs across varying rates and currencies, letting you weigh hashpower against power draw, space, noise and lifecycle considerations before you commit.

Like a dreaming city, the IceRiver KS5L concentrates purpose into compact steel and silicon. The unit is built for Kaspa's KHeavyHash and runs between a nominal 9 TH/s and peaks near 12 TH/s under ideal conditions. It consumes roughly 3400 watts and averages near 283 joules per terahash, a figure that favors operators who prioritize energy efficiency. The footprint is small at 370 x 195 x 290 mm and the weight is 15 kg, which simplifies rack placement and dense installations. Cooling combines a multilayer heatsink array with four 120 x 120 x 38 mm fans to hold temperatures steady and extend component life. Electrical design uses a highly optimized power delivery network and a reinforced PCB to reduce losses and suppress electromagnetic interference, maintaining consistent hash rates in crowded deployments. Firmware adds adaptive frequency tuning that shifts performance to match workload and ambient conditions without manual tuning. A proprietary control board and an easy web interface enable remote monitoring, management and firmware updates to lower hands-on maintenance. Rated to operate in 0–35°C and 10–90% relative humidity, the KS5L suits a wide range of environments. In short, it blends compact form, deliberate thermal management and power-tuned efficiency to reduce operational friction and support sustained uptime.

KHeavyHash is a cryptographic hash function that serves as the backbone of Kaspa proof-of-work consensus mechanism. This algorithm processes input data of any length and produces a fixed hash value, ensuring security and integrity in the mining process.
