Solo CPU block with integrated pump

The Alphacool Eisbaer Aurora Solo combines a nickel-plated copper cold plate with a built-in DC-LT 2 ceramic pump. It is sold as the core unit for builders who want to assemble a custom liquid-cooling loop rather than use a pre-filled AIO. Standard G1/4-inch threads accept any industry fittings, letting you choose tube size, coolant colour and radiator layout. The compact body measures 66 by 66 by 69 millimetres.

Quiet ceramic pump handles CPU and GPU loop

The integrated DC-LT 2 ceramic pump runs almost inaudibly at normal speeds while delivering enough flow for a circuit that includes a radiator, this CPU block and a graphics-card water block. Fine fin structures on the cold plate and optimised water channels keep thermal performance on par with larger DIY coolers. No fan or radiator is included, so system noise depends entirely on the external components you select.

Replaces pre-filled AIOs when you need full loop

This unit suits enthusiasts who want to pick every fitting, tube and coolant themselves instead of accepting a sealed all-in-one design. It is not for builders who need a ready-to-mount cooler with included radiator and fans, or for anyone unwilling to plan and assemble a custom loop. The jump is worth it when you want expandable cooling that can later cover a GPU without replacing the pump.

Questions about this item

How do I mount the Eisbaer Aurora Solo on my Intel or AMD socket, and which step do people skip?

Fasten the included mounting hardware for your specific socket, then connect the G1/4" fittings before filling the loop — skipping the fitting install leaves the block unconnected.

What part will need replacement first if I run this loop continuously?

The DC-LT 2 Ceramic pump is the only moving component; its ceramic bearing wears over time and will require a pump swap before the copper cold plate degrades.

At what point does the integrated pump become the bottleneck in a sustained loop?

The DC-LT 2 Ceramic pump is rated for a circuit with one radiator, this CPU block, and one GPU block — adding a second radiator or restrictive blocks exceeds its flow capacity.
