Lianli Hydro Cooling Radiator (4.5 KW) is 4.5KW external water cooling radiator from Lianli for air cooled ASIC miners converted to water cooling via waterblock retrofit kits. Handles one converted miner up to approximately 3,500W thermal load (S19, T19, S19j Pro class). Integrated pump, 8 silent aluminum condenser fans at 500 to 4,500 RPM, 4 operating modes. 60 dB versus 80 dB air cooled noise. Universal 90 to 305V. 12mm inlet/outlet. CE certified. 15 kg. 1 year warranty. Not for factory hydro miners; those need the 12KW model.
Standalone heat dissipation for ~4 kW of hydro miner load, compatible with Antminer, Whatsminer, Avalon, Ipollo, Innosilicon.

The Lianli 4.5KW radiator converts the mining noise problem into a solvable engineering challenge. Stock air cooled ASICs run 75 to 80 dB, ruling out home offices, garages shared with living space, and most small commercial environments. Pair a Lianli waterblock retrofit kit (sold separately, model specific) with this radiator, and operating noise drops to approximately 60 dB while maintaining stable chip temperatures through consistent coolant circulation. The unit is self contained. Integrated water pump, exhaust system, and 8 fans behind an aluminum condenser all run from a single 90 to 305V power input via C14 socket. No separate pump, no external power supply. Connect 12mm silicone tubing from the waterblock on your miner to the radiator's 12mm inlet and outlet, fill with distilled water or coolant, power on. Exhaust air runs 35 to 65 degrees Celsius and can be redirected for space heating in cold climates. Four operating modes: manual (twist control, 500 to 4,500 RPM), low temperature for quiet nighttime operation, high temperature for summer, and water temperature maintenance for automatic fan adjustment to target coolant temperature. Front panel detaches for fan maintenance. Compatibility covers Antminer, Whatsminer, Avalon, Ipollo, and Innosilicon hardware converted via Lianli waterblock kits. Handles miners up to approximately 3,500W thermal load: S19, T19, S19j, S19j Pro, S19k Pro class. For the S21 XP at 3,645W, the 8KW model provides safer margin. For factory hydro miners (S21 Hydro, S23 Hydro, Whatsminer M53/M63 series), the 12KW model is required per Vipera documentation. Lianli's lineup spans three tiers: 4.5KW (this product, one converted miner), 8KW (one overclocked or higher power converted miner), 12KW (factory hydro miners or two converted miners below 25 degrees ambient). CE certified. 15 kg. Stainless steel fittings. 1 year manufacturer replacement parts warranty. Currently out of stock at MillionMiner. Free DDP delivery when available.
The 4.5KW is Lianli's entry tier radiator for operators converting air cooled ASICs to water cooling. Drop the 80 dB fan noise of a stock S19 or T19 down to approximately 60 dB through waterblock conversion, opening home and small commercial deployment that stock noise levels make impractical. All in one integrated design: built in water pump, exhaust, and 8 silent fans behind an aluminum condenser. Connect 12mm silicone tubing from your Lianli waterblock to the radiator, fill with distilled water or coolant, power on. Four operating modes handle different scenarios: manual fan control (500 to 4,500 RPM twist adjustment), low temp for quiet operation, high temp for summer, and auto water temperature maintenance for hands off cooling. Critical sizing note: the 4.5KW handles one converted miner up to 3,500W. Factory hydro miners (S21 Hydro, S23 Hydro, Whatsminer M53/M63) need the Lianli 12KW. Universal 90 to 305V. CE certified. 15 kg. 1 year warranty.

External water cooling for one air cooled ASIC miner converted via Lianli waterblock retrofit kit. 4.5KW thermal capacity covers miners up to 3,500W (S19, T19, S19j Pro class). Integrated pump and 8 aluminum condenser fans. 60 dB operation versus 80 dB air cooled. 4 modes: manual, low temp, high temp, auto water temperature maintenance. Universal 90 to 305V. 12mm connections. CE certified. 15 kg. Not for factory hydro miners like S21 Hydro or S23 Hydro; those require the Lianli 12KW model.
One miner up to 3,500W. Not for factory hydro ASICs. Those require the 12KW model from Lianli.
All in one design. No separate pump needed. 60 dB versus 80 dB air cooled noise. 90 to 305V universal.
Manual fan control, low temp, high temp, and auto water temperature maintenance. Front panel detaches for easy cleaning.
External water cooling for one air cooled ASIC miner converted to water cooling via a Lianli waterblock retrofit kit. Handles up to 3,500W thermal load. Compatible miner classes: Antminer S19, T19, S19j Pro, S19k Pro, and equivalent Whatsminer, Avalon, Ipollo, and Innosilicon hardware.
No. The 4.5KW model lacks capacity for factory hydro miners drawing 5,000W+. Per Vipera (certified reseller), factory hydro ASICs (S21 Hydro, S23 Hydro, Whatsminer M53/M63 series) require the Lianli 12KW model. Using the 4.5KW on those machines risks overheating and hardware damage.
Integrated water pump, exhaust system, and 8 silent aluminum condenser fans. Powers from a single 90 to 305V input. No separate pump or external power supply needed. Tubing and waterblock kit purchased separately.
Manual: twist control for direct 500 to 4,500 RPM fan speed. Low temperature: reduced fan speed for quiet operation. High temperature: maximum cooling for hot climates. Water temperature maintenance: automatic fan adjustment to maintain target coolant temperature.
12mm water inlet and outlet. Use standard silicone tubing with 12mm inner diameter. Stainless steel fittings included. Fill with distilled water or water glycol coolant. Avoid tap water due to mineral buildup.
niversal 90 to 305V via C14 socket. Works on 110V North American, 220V European, and everything in between. No voltage conversion or adapters needed.
Yes. The radiator handles external heat rejection only. You need a Lianli waterblock retrofit kit specific to your miner model to replace the stock air cooling inside the chassis. Radiator and waterblock are separate purchases.
The S21 XP draws 3,645W, approaching the 4.5KW limit. It would work under mild ambient conditions but leaves minimal thermal margin. The 8KW model is the safer choice for anything above 3,500W.
1 year manufacturer replacement parts warranty. Covers defects under normal operation within rated capacity. Does not cover damage from deploying on miners exceeding the 4.5KW thermal rating.
Three benefits: noise drops from 80 dB to 60 dB, chip temperatures run more consistently (potentially extending hardware life), and waste heat concentrates at the radiator exhaust rather than dispersing throughout the room. Tradeoff: upfront cost for waterblock kit plus radiator, and ongoing coolant maintenance.
