What customers say
Enthusiasts overwhelmingly praise the Alphacool Eisblock Aurora for its exceptional thermal performance and striking aesthetics. Users consistently report dramatic temperature reductions, keeping the RTX 4090 cool under heavy loads, which maximizes boost stability. The build quality is highly regarded, featuring robust materials and vibrant Aurora RGB lighting that enhances custom loops. The integrated backplate is a significant benefit for rear component cooling. While the initial mounting process demands patience due to the Aorus PCB size, the resulting fitment and minimal flow restriction are excellent. This block delivers extreme cooling performance, justifying its premium positioning for users prioritizing peak results and visual appeal.
Know before you buy
No, this specific model is engineered exclusively for the Gigabyte Aorus Master RTX 4090. Because the PCB layout is unique to the Aorus Master, it will not fit other RTX 4090 variants.
The included backplate is designed to provide structural support and passive thermal dissipation. It helps draw heat away from the rear of the PCB, but it does not feature active liquid cooling channels.
The block features standard G1/4" threads, making it compatible with the vast majority of custom liquid cooling fittings on the market. You can use either hard-tube or soft-tube fittings depending on your loop design.
The lighting uses a standard 5V 3-pin ARGB connector. You can connect it directly to your motherboard's ARGB header or a dedicated lighting controller to sync the effects with the rest of your system.
The Nickel-Plexi construction is durable, but it is important to use high-quality, non-conductive coolant to prevent potential staining or corrosion. Avoid using harsh cleaning agents on the plexi surface to maintain its clarity and structural integrity.
