EK-Thermosphere is a high-performance universal GPU water block built off EK-Supremacy cooling engine, designed specifically for the use with EK-FC Terminal interconnects in multiple graphics card system.
The Thermosphere cooling engine uses similar, yet refined as per needs of modern microprocessors, fin design as its ancestor. The cooling liquid accelerates through jet plate's nozzle and turbulently continues its path through numerous very thin channels which provide extreme cooling surface area. EK-Thermosphere can also work flawlessly with reversed water flow which does not affect the cooling performance.

The base is made of nickel plated electrolytic copper, backbone is made from laser cut brushed stainless steel plate while the top is made of quality POM Acetal material. The sealing is ensured by quality rubber washers.
Screw-in brass standoffs are pre-installed in each exchangeable mounting plate and allow for safe, painless installation procedure. Block is mounted with enclosed M3x4 DIN7985 screws.
G1/4" threaded fittings can be used on both sides of the FC terminal. Up to four EK-Thermosphere water blocks can be used on a single ATX form factor motherboard by using EK-FC Terminal (DUAL, TRIPLE or QUAD type) system or other means of interconnectivity. Please note that EK-FC Bridge & Link system is not compatible with this water block.
GPU compatibility:
EK-Thermosphere series water blocks support the majority of modern nVidia® and AMD® high-end graphics cards via exchangeable mounting plates. The product comes factory pre-fitted with mounting plate G80 (mounting pattern 58x58mm) and ready for use on modern nVidia® GeForce® GTX graphics cards only. Please check compatibility at EK's CoolingConfigurator.
To use this product on AMD and other nVidia graphics cards it is mandatory to purchase additional mounting plates:
- G92: 53x53mm
- R600: 54x54mm
- GF560: 51x61mm
- G200: 61x61mm
Enclosed in the box:
- EK-Thermosphere series water block /w pre-installed G80 mounting plate
- Mounting mechanism
- Necessary mounting screws and washers
- Thermal grease (TIM) EK-Ectotherm (1g)
- 2x EK plug G1/4"
EK-Quantum Vector N+ RX 6800XT/6900XT is a 2nd generation Vector GPU water block from the EK® Quantum Line. It is made for SAPPHIRE NITRO+ 6800XT and 6900XT graphics cards based on the latest AMD® RDNA2™ architecture. For a precise compatibility match of this water block, we recommend you refer to the EK Cooling Configurator.

EK-Quantum Vector N+ RX 6800XT/6900XT water block is compatible with SAPPHIRE NITRO Radeon RX 6800XT, and 6900XT graphics cards. The Vector water block directly cools the GPU, VRAM, and the VRM (voltage regulation module) as a cooling liquid is channeled right over these critical areas. The water block is in contact with power stages as well as Inductor chokes to maximize cooling and minimize the chances of coil whine.

These newly developed water blocks feature optimized flow paths that reduce hydrodynamic instabilities and vortexing (dead spots) inside of them. The EK-Quantum Vector Series water blocks use an Open Split-Flow cooling engine design, which proved to be a superior solution for GPU water blocks. It is characterized by low hydraulic flow restriction, meaning it can be used with weaker water pumps or pumps running on low-speed settings, and still achieve top performance. The jet plate and fin structure geometry have been optimized to provide even flow distribution with minimal losses and optimal performance when used in any given coolant flow orientation.

The base of the block is CNC-machined out of high-grade nickel-plated electrolytic copper, while its top is CNC-machined out of durable black POM Acetal. These 2nd generation Vector GPU water blocks also feature acetal terminals. The watertight sealing is ensured by high-quality EPDM O-rings, while brass standoffs are already pre-installed and allow for a safe and easy installation procedure.
The aesthetic end-piece is housing the addressable D-RGB LED strip. These water blocks boast a total of 9 individually addressable RGB LEDs, and a LED-lit terminal. They are compatible with popular RGB sync technologies from all major motherboard manufacturers. The arrow marking on the 3-pin D-RGB LED connector is to be aligned with the +5V marking on the D-RGB (addressable) header.

EK recommends the purchase of a retention backplate, which improves the overall aesthetics of your graphics cards, and also provides additional passive cooling for the GPU core and backside of the printed circuit board VRM and VRAM sections.
