EK vs Phanteks Cooling Parts
coolant type
EK offers the CryoFuel Premix Coolant, a 1000ml liquid designed for immediate use. This premix formula is ready to pour directly into your loop without additional preparation. It features low electrical conductivity to protect your components from short circuits. The formula is also non-toxic and eco-friendly, with 90% biodegradability within ten days. Phanteks does not provide a liquid coolant in this product. Their Glacier R220C is a hardware component, not a fluid. You will need to source coolant separately if you choose the Phanteks reservoir. For those who want a ready-to-use fluid, EK provides the necessary chemical solution.
reservoir capacity
The Phanteks Glacier R220C Acrylic Reservoir holds 200ml of coolant. This capacity is suitable for standard loops but limits the total fluid volume in larger builds. The EK product is a 1000ml bottle of coolant, not a reservoir. It does not store fluid in your loop; it supplies the fluid itself. If you are comparing storage volume, the Phanteks unit provides the physical tank space. The EK item provides the liquid medium. You cannot compare a tank to a bottle of fluid directly. However, the Phanteks reservoir defines how much coolant your loop can hold at once.
lighting
Phanteks integrates Digital-RGB lighting into the Glacier R220C reservoir. This lighting allows for immersive visual effects and can synchronize with compatible Phanteks cases or motherboards supporting a 3-pin drgb header. The EK CryoFuel Clear Premix Coolant has no lighting capabilities. It is a transparent fluid designed for thermal efficiency and vivid color when mixed with pigments. If you want visible illumination, the Phanteks unit provides the hardware for it. The EK product relies on the clarity of the fluid and the transparency of your fittings for visual appeal. Lighting is exclusive to the Phanteks component.
material compatibility
EK specifies that its coolant is compatible with Acrylic, PeTG, POM Acetal, and various rubbers like NBR, ePDM, and Norprene. This ensures safety for common loop materials. The Phanteks Glacier R220C is constructed from transparent acrylic with a Viton rubber O-Ring for sealing. The material of the reservoir itself is acrylic, which matches the compatible materials listed by EK. You can use EK coolant with the Phanteks acrylic reservoir without risk of degradation. Both products support standard acrylic construction. The EK coolant is formulated to protect these materials while maintaining thermal performance.
pump compatibility
The Phanteks Glacier R220C is explicitly designed as a combo reservoir for DDC pumps. It integrates the pump directly into the reservoir body. This simplifies loop planning by combining two essential components. EK does not offer a pump or pump/reservoir combo in this listing. The EK product is solely a coolant fluid. It has no mechanical interface for a pump. If you need a combined pump and reservoir unit, the Phanteks option provides this integration. The EK product requires you to source a separate pump and reservoir hardware. Pump compatibility is a feature of the Phanteks hardware.
