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 cast acrylic material. The sealing is ensured by quality rubber washers.
The top also features two pre-drilled slots for 3mm LED diodes.
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 EK-TIM Ectotherm (1g)
- 2x EK plug G1/4"
EK-MOSFET MSI X99 XPower is a water block for water cooling of the power regulation (VRM / MOSFETs) module on MSI X99S XPOWER AC motherboard. It features a high flow design allowing the water block to be easily used with systems using weaker water pumps.

Base is made of nickel-plated electrolytic copper while the top is made of quality acrylic glass material. The sealing is ensured by the use of quality rubber gasket.
This product features preinstalled nickel-plated brass standoffs. Enclosed is also a EK engineered backplate, made from black anodized aluminium, which improves heat transfer by cooling the back side of the circuit board as well.
Enclosed:
- EK-MOSFET MSI X99 XPower series water block
- thermal pads
- mounting mechanism
Fittings are not enclosed! Two fittings are needed to complete the installation!
