Included in the installation is precision installed performance thermal pads on all graphics card hot spots including the memory modules and VRM that will increase the thermal conductivity of the Graphics Card Block and allow maximum heat transfer from your performance hardware into your custom watercooling setup.

To install and run an Overclockers UK Tech Labs H2O Custom Graphics Cards in your system, you will need to use appropriate watercooling hardware to support the cooling potential of the block.
Overclockers UK recommends the following for optimised performance:

- A Thick 240mm Radiator for a loop including a single Overclockers UK Tech Labs H2O Custom Graphics Card
A 360mm Radiator for a loop including a single Overclockers UK Tech Labs H2O Custom Graphics Card and a high performance quad core CPU
- A Thick 360mm Radiator for a loop including a single Overclockers UK Tech Labs H2O Custom Graphics Card and an overclocked quad or hex core CPU
- A 480mm Radiator for a loop including two Overclockers UK Tech Labs H2O Custom Graphics Cards and a high performance quad core CPU

These figures should be used as a rough estimate and we suggest that if adding more items into your watercooling loop that you take appropriate measures to enhance your cooling system.
Overclockers UK Tech Labs H2O Custom Graphics Cards provide the perfect platform for GPU overclocking by giving your Graphics Card optimised running conditions to perform at its best and allow you to overclock your system to higher frequencies whilst keeping the Processor and power array on your Graphics Card at a lower operating temperatures.

The 980 operates at extremely low temperatures and has massive overclocking headroom out of the box, but the addition of a waterblock really allows the user to push the card to its limits easily and safely.

I have a pair of these in my new rig. They are truly AWESOME!! I got them with blue backs, so they match my colour scheme. I ordered them by phone and the support I got was really helpful and friendly. They also arrived several days sooner than I was expecting. Perfect!



Got the Acetal+Nickel version with backplate, temps at 29


Excellent cards, service could have been

I ordered two of these at the end of 2014 and have been pleased overall.


The cards are some random unbranded 980 reference variant (which surprised me), but despite this they are performing well. Having run them at stock levels for over 3 months I've had no problems. A MAJOR disappointment was that I did not receive the stock air coolers for either card (or connectors, sli bridge or anything just a card in a box), which will practically eliminate any 'sell-on' potential when they are eventually replaced.


Took over 10 days to build and ship which would have been even longer had I not chased to discover the hold-up (my chosen colour of backing plate was out of stock). It would have been nice to receive a call to inform me of the delay. After 3 days I phoned, found out about the delay, and I suggested swapping to a different colour of backing plate to speed things up (The cards actually look great with the new gold backplates as opposed to the black I had originally ordered). Obviously there is going to be some lead time with a custom card like this, but I felt that nearly two working weeks was a touch excessive.

Overall they seem to be great cards at a good price which I would recommend. The 2 year warranty is a big plus (which is the only reason I didn't do a diy build this time).


Great card

I am very happy with this card. The work done one it was excellent and the stock cooler was even included in addition. It performs like a dream (Have it at 35C with my loop). I plan to be getting a second one soon
