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. Other heat generating components (such as RAM and VRM integrated circuit) need alternative cooling method (fan and/or self adhesive heatsinks).

"We're pleased to introduce our new conceptually new universal GPU water block," said Niko Tivadar, EK-Thermosphere main designer and Product Manager of EKWB. "EK-Thermosphere is a new addition to our Clean CSQ industrial design line and features very slim construction, thanks to completely new architecture. Unmatched thermal performance and even more straight-forward installation procedure than before are key features of this product. Hooking up liquid cooling to four GPUs has never been easier."

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.

Base is made of electrolytic copper, backbone is made from laser cut brushed stainless steel plate while the top is made of quality POM Acetal material. Screw-in brass standoffs are pre-installed in each exchangeable mounting plate and allow for safe, painless installation procedure. 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. Additionally, plexi top variants also features two pre-drilled slots for use of 3 mm LED diodes.

GPU compatibility:
EK-Thermosphere series waterblocks supports majority of modern NVIDIA and AMD high-end graphics cards via exchangeable mounting plates. The product however comes factory pre-fitted with mounting plate G80 (mounting pattern 58x58 mm) and ready for use on modern NVIDIA GeForce GTX 500, -600 and -700 series 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: 53x53 mm
  • R600: 54x54 mm
  • GF560: 51x61 mm
  • G200: 61x61 mm

Enclosed in the box:
  • EK-Thermosphere series water block /w pre-installed G80 mounting plate
  • mounting mechanism
  • thermal grease (TIM) EK-Ectotherm (1g)

EK-Thermosphere water blocks are available in several different variants and are readily available for purchase through EK Webshop and Partner Reseller Network.

Would it really be so much work for them to allow you to order whichever plate you need rather than include one in the price that you mostly will have to throw away and then force you to pay again for the actual one you need?

Only if you don't know what you're doing when mounting a GPU-only block.
Exactly. It looks pretty great for a universal block, and if you don't mind mounting ram/vrm sinks, then it seems like a very viable option. Personally, I'm not that acquainted with it so I'll need to stick to full cover blocks. ;)

I wonder how these compare to watercools universals
I decide to go on Thermosphere instead full cover waterblock now at begin of June.
It's to much for me to pay 220-250e over reference models when I change graphic cards.
It's one excellent motherboard. And I will hard to sell waterblock, this I can use for next card and
need to pay 100e over reference model for custom design.
For me at this moment for people who wish every part to be similar style no better option than combination EK Sumpremacy Clean CSQ, EK D5 X-Top pump included and Thermosphere or full cover depend what customer want.
