NZXT Technologies Kraken G10 Liquid Cooled GPU Bracket RL-KRG10-B1 Black

Kraken G10 x2 installed on 2x GTX 770 SuperClocked Dual Bios 4GB with Corsair H90 cooler.I would have gone full watercooling loop to cool my graphics cards but there was no "full block" available for my card. So this was the cheapest and most effective route and did not disappoint.Installation was as expected, not too hard. I left the metal front-plate/passive heat sink on, but had to modify the plate slightly with the dremel tool to cut back the 4 tabs around the GPU by about 1/8 inch each (this includes part of the aluminum nut, shaving off to just before the threads). This allowed the H90 block to sit with about 1/32" of clearance all around. I also installed copper VRAM-size heatsinks on top of the plate to assist with cooling, directly over the VRM chips.Performance has been excellent. About a 40% drop of temps as advertised. Was hitting 80 degrees in benchmarks and games, even with fan profile set to full RPM at 75c. Now I hit about 45-50 in the same situation, with absolute max around 60 degrees after a few hours. This is with the H90 with 2 silverstone generic 140 fans running about 50% speed (totally silent). I used the silverstones because the included H90 corsair fans were rattling and extremely noisy. If I up the speed of the fans, I get an additional 5-10c drop but to me I want silent, and temps are cool enough, so I keep them at 50%. This is also with a 50core+300memory overclock on both cards.All in all, highly recommend this product, it allowed me to finally +OC my graphics cards and keep them dead silent in the process... before, stock (factory OC) resulted in very noisy GPU fans all the time when under load and throttling of the card at 80c which hurt perf with fps spikes at times. But be sure to check out your VRM situation to make sure these get cooler by more than just fan air on direct chip. I used a temp probe and am getting max 70c on the back of the card above VRMs at max load, using the included passive heatsink plate that came with the card + the copper heatsinks added on the plate to help. I am guessing around 80c is the actual VRM max temp under load.

I purchased the blue version, mostly for the cost ($10-20 less than other colors) but it does match my G.Skill Ram & Blue LED lights so that is a plus. However it's just painted metal so I'm not sure why the price variations in colors.Pros+ Cheap+ EffectiveCons- Weakens the mounting for your GPU- 92mm Fan is loudInstallation:I was using this on a EVGA GTX 770 Reference Card with a Kraken X40 Liquid Cooler. The Kraken X40 does come with a locking ring to lock the pump in place, but that only works on the CPU bracket and not this GPU bracket. Since this is an NZXT product it would be nice if they included a locking ring that works with the G10 and it would work with other models as well. This way you aren't trying to manage multiple things at the same time during installation and it just makes life easy. For the record the locking ring that comes with the X40 will work on the G10, but the minute you move the radiator the ring pops off because the G10 has a thicker surface for it to snap in place. I ended up ditching the ring idea and managed to get it installed.Performance:I changed my setup from an Ibuypower Revolt case to a Coolermaster CosmosSE Case so that may have an impact on cooling performance. Max Temperatures in the Revolt case would hit 70-80c (70mhz OC). Inside the Cosmos with the G10 bracket and running Heaven with 120mhz OC, the temperatures aren't moving past 55-56cCase Fitment:This was an issue because I tried initially having everything neat and clean, ziptieing along the side of the fan as its designed to do. The X40 tubing, which is 16" had no where to mount inside my case. I ended up removing the zipties and letting the radiator/fan sit against the HD Cage and it shouldn't move or be interfered by anything.Conclusion:This will help degrease GPU temperatures and allow you to squeeze more out of your overclock. I would run a 70mhz OC on Aircooled and now able to run a 120mhz OC. The fan is noisy and the installation can be a little annoying but it works and works well.

I purchased this for use with my R9 290. I love the color choices for this bracket and the fact that it is very lightweight. For GPU cooling, this thing rocks, but it unfortunately leaves the VRM and VRAM exposed to the elements. This bracket requires extra purchases to complete proper cooling. A GLEID kit will fit under the bracket, however, even that doesn't come with enough heatsinks to cover all of the VRAM. To be fair, the VRAM is fairly well cooled by the fan, though I think the heatsinks are really a necessity. Why spend the money to watercool your GPU if you're going to let the card around it burn up?I think if the design was a shroud or possibly came with some sort of heatsinks to compensate, it would be a perfect design. Short of that, it's still a great bracket and a cheap, easy way to add watercooling to your GPU.
