Who We Recommend
EK-FC7990 is a high performance full-cover water block engineered specifically for PowerColor/VTX3D/Club3D Radeon HD 7990 series graphics cards. Please check our Cooling Configurator online compatibility system for detailed compatibility list!
This water block directly cools both GPUs, RAM as well as both VRMs (voltage regulation module) as water flows directly over these critical areas thus allowing the graphics card and it's VRM to remain stable under high overclocks. EK-FC7990 water block also features a very high flow design therefore it can be easily used in liquid cooling systems using weaker water pumps.
Base is made of nickel plated electrolytic copper while the top is made of quality POM acetal material. The sealing is performed by quality rubber washers. Screw-in brass standoffs are pre-installed and allow for safe, painless installation procedure.
EK also encloses the EK-FC7990 Backplate made of high precision CNC milled aluminium with black anodized finish. This backplate directly cools the memory IC on the backside of the circuit board as well as serves as an aesthetic add-on.
Two-slot I/O bracket which replaces the original three-slot, in order to make installation of mutliple graphics cards easier, is also enclosed.
Up to four EK-FC7990 water blocks can be interconnected using EK-FC Terminal system or other methods of interconnectivity. This water block does not align with any other FC water block. This water block is not compatible with EK-FC Bridge CSQ series interconnect!
We were able to get ONE MORE RUN made of these and expect delivery 2nd week of March.

Initially I was very disappointed to see EK discontinue this specific block for my powercolor 7990, and was contemplating selling the card for this reason. However when I was notified that frozecpu had one more batch made by EK, I was ecstatic. Purchased this block about 4 months ago. Temperatures dropped from 80C underload to 45C MAX. Excellent build design and everything is working as it should, very impressed. Great job to everyone at EK and thanks again FCPU.

Really controls temps. Under full load, overclocked to 1075/1500 from 900/1375, temps do not clear 55c. Only complaint: backplate for passive cooling of the RAM gets very hot. Opposite side of card is cool to the touch, but the back plate is nearly hot enough to begin to burn your hand. Wish there was a better way to cool this. Maybe a link to a very thin water block on this side?

Easy to install, dropped temps from stock 7990 cooler 50c+ idle to 41c idle and 70c+ load to low 60''s load with the EK-FC7990 block.
Excellent Fit and Perfromance03-10-2013

Fit is excellent, performance outstanding. Allowed 1250MHz Core and 1475Mhz Memory Overclock @ 1.17V. Using two (2) Powercolor AX-7990 in crossfire running 16 units of WCG 24/7 and the GPU temps stay below 41C on both cards. The performance of the EK-FC7990 is exceptional and I would recommend this water block to anyone running a 7990 video card. Air 42-44C idle, EK water block 40-41C full load. I have been using other guys blocks for years and the EK-FC7990 has the best RAM and VRM fittage of any of them. 9.5 out of 10. (the GPU surface could have been better)
