## Summary description

Alphacool 18651 is a transparent coolant designed for computer cooling systems. It operates at a maximum temperature of 105°C and comes in a pack of 1. This coolant ensures efficient heat transfer and optimal performance for your cooling setup.

## Long description

Alphacool 18651 Transparent 105°C coolant is a clear fluid formulated for liquid-cooled computer systems. It is designed to provide efficient heat transfer while remaining visually neutral in transparent and windowed setups. Rated for operation up to 105°C, this coolant supports stable thermal performance across a wide range of workloads and system configurations.
Advantages
This transparent coolant offers low-viscosity flow for consistent circulation in pumps and radiators and resists clouding over time to maintain system clarity. Its thermal stability at temperatures up to 105°C helps prevent degradation under high-load conditions. The formulation reduces the risk of deposits and supports reliable heat exchange between components and the cooling loop.
Suitable for
Custom liquid-cooled desktop PCs with visible reservoirs and tubing
High-performance workstations and gaming systems requiring efficient heat dissipation
Test benches and open-loop cooling setups where visual neutrality is desired
Key specifications
Appearance: transparent, clear fluid
Maximum operating temperature: 105°C
Package quantity: 1 unit
Compatibility: intended for closed-loop and open-loop computer liquid cooling systems using standard coolant-compatible materials (metals, plastics, and rubber) when manufacturer guidelines are followed
How to use
Flush and clean the cooling loop according to the system manufacturer’s guidance before filling. Pour the coolant slowly into the reservoir while the pump is off, then run the pump briefly to purge air and top up as needed. Monitor the loop for leaks and allow the system to circulate for a short period, checking for clouding or unexpected residues. Follow standard safety precautions such as avoiding skin contact and keeping the fluid away from electrical components during filling.
Usage recommendations
Use this transparent coolant with compatible tubing and reservoir materials and perform periodic maintenance: inspect for particle buildup, replace coolant per your cooling system’s maintenance schedule, and avoid mixing with unknown additives or other colored coolants to maintain transparency and thermal performance.
