EK-FC780 GTX Lightning - Acetal+Nickel

EK-FC780 GTX Lightning is a high performance full-cover water block engineered specifically for MSI design GTX 780 Lightning series graphics cards. Please check our Cooling Configurator online compatibility system for detailed compatibility list!

This water block directly cools the GPU, RAM as well as VRM (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-FC780 GTX Lightning 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 ensured by quality rubber washers. Screw-in brass standoffs are pre-installed and allow for safe, painless installation procedure. Block is mounted with enclosed M3x4 DIN7985 screws. Original backplate can also be re-used with the use of enclosed M4x6 DIN7985 screws.

G1/4" threaded fittings can be used on both sides of the FC terminal. Flow orientation doesn't matter and is thus not prescribed.

Up to four EK-FC780 GTX Lightning 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.

Amazing Build Quality + Feel

Recently bought 2 of these for my SLI setup, and they have got to be one of the best quality waterblocks i have purchased for my videocards over the years. The VRAM thermal pads that come with this are precut and extremely easy to put install. Firstly the actual look of these blocks are really nice, they are solid and meety, and have a nice feel of quality behind them! They are really heavy too which helps with temps. After installing them my graphic cards sit at around 30C and my CPU at around 45, these blocks are that good that they are providing extra passive cooling as well!

On a side note: if anyone wants to use their original backplate with this they will need to re-drill the holes on their backplate. Backplate = M2.5 size hole, but requires M3 for EK waterblock screws. This is also mentioned on the install sheet :)


Amazing build quality & feel

Recently purchased 2 of these for my 780's and could not be more happy with these! The build quality and sturdiness of these waterblocks is insane! The pre-cut thermal pads fit perfectly and were such an ease to install. They are nice and heavy which is always a feel for quality to me. they also keep both my 780s at around 30C at idle and upto 50C on full load, 30C idle when my cpu is running at 45, means that these blocks are doing alot of passive cooling as well!!
