Product Details

Lianli 8KW Hydro Cooling Radiator for S21 XP, S21 Pro, and High Power Converted ASIC Miners: Specifications and Sizing Guide

The Lianli 8KW radiator exists because the 4.5KW model tops out at approximately 3,500W thermal capacity, which excludes most current generation Bitcoin miners. The S21 XP draws 3,645W. The S21+ draws 3,876W. The S21 Pro draws 3,510W. Overclocked S19k Pro units push beyond 3,500W. All of these need more cooling headroom than the 4.5KW provides but do not need the 12KW model built for factory hydro ASICs. The 8KW handles one converted miner in the 3,500W to 7,000W thermal range with comfortable margin. That covers every current gen Bitmain air cooled miner, every MicroBT Whatsminer M70 series air cooled variant, and most Canaan Avalon current gen hardware when paired with the appropriate Lianli waterblock retrofit kit. Same integrated architecture as the 4.5KW: built in water pump, exhaust, aluminum condenser fans adjustable from 500 to 4,500 RPM, single 90 to 305V power input via C14 socket. Four operating modes: manual twist control, low temperature for quiet nighttime operation, high temperature for summer, and auto water temperature maintenance for hands off cooling. Exhaust air runs 35 to 65 degrees Celsius and can be redirected for space heating. The noise case is the primary purchase driver at this tier. An Antminer S21 XP at 75 dB is industrial hardware that requires a dedicated facility. The same S21 XP converted to water cooling with this 8KW radiator at ~60 dB becomes deployable in residential garages, insulated basements, and dedicated home mining rooms. That 15 to 20 dB reduction represents roughly 75 percent less perceived loudness, which is the difference between "needs a warehouse" and "works in my garage." Critical limitation per Vipera (certified Lianli reseller): the 8KW model is only for waterblock retrofit conversions of air cooled ASICs. Factory hydro miners (Antminer S21 Hydro, S21 XP Hydro, S23 Hydro, Whatsminer M33S+, M53, M53S, M63, M63S) require the Lianli 12KW model. The factory hydro units draw 5,000W+ thermal load with different coolant flow requirements. 12mm water inlet and outlet. Standard silicone tubing with 12mm inner diameter. Stainless steel fittings. Fill with distilled water or water glycol coolant. CE certified. 16 kg per Zeus Mining. 1 year manufacturer replacement parts warranty. Currently out of stock at MillionMiner. Free DDP delivery when available.

Lianli 8KW Hydro Radiator: The Mid Tier for S21 XP and S21 Pro Class Waterblock Conversions

The 8KW fills the gap between Lianli's 4.5KW entry tier and 12KW factory hydro tier. Operators converting current gen hardware like the Antminer S21 XP (3,645W), S21 Pro (3,510W), or S21+ (3,876W) to water cooling need more thermal headroom than the 4.5KW provides but do not need the 12KW model designed for factory hydro ASICs. Same integrated all in one design as the 4.5KW: built in water pump, exhaust, aluminum condenser fans, single 90 to 305V power input. Connect 12mm silicone tubing from your Lianli waterblock to the radiator, fill with distilled water or coolant, select one of four modes (manual, low temp, high temp, auto water temperature maintenance), power on. The noise reduction argument is strongest at this power tier. An S21 XP running stock air cooling at 75 dB makes home deployment impractical. Converted to water cooling with this radiator at ~60 dB, the same hardware becomes viable in garages, basements, and dedicated home mining rooms. CE certified. 16 kg. 1 year warranty. Currently out of stock at MillionMiner.

Frequently Asked Questions

One air cooled ASIC miner converted to water cooling via Lianli waterblock kit, drawing 3,500W to 7,000W. Covers: Antminer S21 XP (3,645W), S21 Pro (3,510W), S21+ (3,876W), overclocked S19k Pro, MicroBT Whatsminer M70/M70S/M70S+ (3,140W to 3,500W with overclock headroom), and equivalent Canaan, Ipollo, Innosilicon hardware. Basically every current gen air cooled Bitcoin miner.

The S21 XP draws 3,645W, exceeding the 4.5KW radiator's comfortable operating range of ~3,500W. Running at capacity with zero thermal margin means the radiator cannot handle ambient temperature spikes, overclocked operation, or sustained summer heat. The 8KW gives genuine headroom for reliable year round operation on current gen hardware.

No. Per Vipera (certified reseller), the 8KW is only for waterblock retrofit conversions of air cooled ASICs. Factory hydro miners (S21 Hydro, S21 XP Hydro, S23 Hydro, Whatsminer M53/M63 series) draw 5,000W+ with different coolant flow requirements and need the Lianli 12KW model.

Integrated water pump, exhaust system, and aluminum condenser fans. Single 90 to 305V power input via C14 socket. No separate pump or external power supply needed. Tubing and Lianli waterblock kit are separate purchases specific to your miner model.

tock air cooled S21 XP or S21 Pro runs 75 dB. Converted to water cooling with this radiator: approximately 60 dB. That 15 dB reduction is roughly 70 percent less perceived loudness. The difference between needing a dedicated facility and being deployable in a residential garage or insulated basement.

Manual: twist control for 500 to 4,500 RPM direct fan adjustment. Low temperature: reduced fan speed for quiet nighttime or winter operation. High temperature: maximum cooling for summer or hot climate deployment. Water temperature maintenance: automatic fan adjustment to hold target coolant temperature without manual intervention.

Universal 90 to 305V via C14 socket. 110V North American, 220V European, Middle Eastern 220 to 240V, all work without adapters or voltage conversion.

Only if both combined draw under 7,000W thermal and ambient stays below 25 degrees Celsius. Two S19j units at 3,050W each total 6,100W, which fits. Two S21 XP units at 3,645W each total 7,290W, which exceeds capacity. For two current gen miners, the 12KW model is the correct choice.

1 year manufacturer replacement parts warranty. Covers defects under normal operation within rated capacity. Does not cover damage from deploying on miners exceeding 8KW thermal load or coolant quality neglect.

Depends on what hardware you already own. If you have a working S21 XP or S21 Pro generating 75 dB noise that prevents home deployment, converting to water cooling with a waterblock kit plus 8KW radiator costs significantly less than purchasing a new factory hydro miner. If buying new hardware from scratch, factory hydro models ship ready to deploy without conversion complexity.
