Watercool ANY Graphics Card! -- Testing the NZXT G12 Bracket

2017-05-15
what's up guys Eber here with hurricane axe and I've been using the gtx 1080i ever since launch and one of the concerns i mentioned in my review video was regarding the core temperatures during load as you may know the reference cooler design wasn't really doing its trick cooling the monster inside even though pascal architecture is efficient the GP 102 core is massive and input a lot of heat as you can see I ran the 3d mark 5 strike ultra on a loop for 15 minutes and the maximum I was able to achieve was around 83 C remember Nvidia's boost algorithms will start modulating core frequencies when the core reaches an operating temperature of around 84 C now this is why a lot of people end up leaning towards custom GPUs since both partners will add new PCBs RGB lighting premium back plates and other exclusive features that might attract gamers in my case I was a little uncomfortable with the temps on this reference card but most importantly sometimes I found its clock speeds to be wandering a bit and I decided to do something about it but before we move on a quick message from our sponsor you can only rely on the pros do the job with every keystroke satisfying like the millions before it call it fooled every key regardless of their state Kula master master keys bro they could live negative now I'm pretty sure most of you are aware of custom aftermarket GP brackets that can be used to mount an AI yo on top of the GPU core Corsair thermal tank and many others have launched them in the past some of them even include lower style fans for the V RMS but the downside to all of this is a it's going to cost you more especially when you include the cost of the EIU cooler and B it might be a little overwhelming for some of you to install this cooling solution now today we're taking a look at the new NZXT kraken g12 GPU bracket it's priced at $30 and you can pick it up either in black or white variants the installation procedure is also supposed to be a lot easier than its predecessor the g10 and it's compatible with more than 30 a i/o coolers on the market so not just n sixties models this is because like many other manufacturers NCHS uses ASA tech as an OEM so mounting compatibility remains identical across many different models compatibility with modern GPUs shouldn't be a problem since the g12 supports both Nvidia and AMD sklearn offerings including the Titan XP and the rx 580 now remember you have to purchase your own cooler of choice provided that you've checked the compatibility list on the website in my case I'm going to mount this hot new Kraken X 42 from NZXT it's priced at $130 so in total you're looking at an investment of $160 USD without any taxes just for the sake of better temperatures and perhaps higher frequencies that's a lot more than what you would pay for a custom GPU but without any further ado let's proceed with the teardown process a few moments later so I've run into a little bit of a problem here and via I have done a pretty interesting job well I guess a little bit more complicated and expected but you first need to remove the back plates in order to you know for the first initial turn on process which I did by removing these screws that are right here super tiny screws and unfortunately they're actually mounted on top of these hex screws for the cooler so I don't actually have a compatible hex screw remover and so I'm going to head out to the dollar store or the nearest hardware store and come back to tear down this whole thing because it's I need to do this today so yeah success so I did find a four millimeter driver it works so yeah I'm gonna get this kit and go back home let's do this guy's all right I have to mention a few things before revealing the results you see mounting a GPU with the a or cooler can be a little bit challenging especially inside compact cases mind you I'm using the X 4200 M NZXT that comes with a 140 millimeter radiator and take this s 340 case from NZXT for instance this chassis has a lot of restraints when it comes to mounting a radiator especially when you're using a 240 or 280 millimeter AIO for your processor I even tried mounting the radiator at the top and the rear but unfortunately the vrm heat sinks on the motherboard was getting the way so to provide an apples-to-apples comparison I chose the be quiet silent based 800 chassis to mount to liquid coolers one for the CPU and one for the GPU also make sure to reuse the thermal pants that come with your stock cooler as I ran into a lot of hiccups without installing them in the first place most of them were mostly bf Saudis but envy exceeds your taking notes please include extra pads in your next revision anyways enough of me complaining let's roll out those results and as you can see these numbers speak for themselves the X 42 does a killer job cooling the GP one or two core providing idle temps around 27 C and there is about an eighth degree difference between it and the stock cooler which might not be a lot but moving on to low temps I ran the Unigine value test on a loop for 15 minutes and once again the X 42 did a fantastic job giving us temps in the high 60s which is way better than 85 C on the stock cooler I also noticed that there wasn't a drastic difference with core frequencies in this case with the a i/o Lemax I was able to achieve without me tweaking was eighteen eighty five megahertz compared to 1873 with the reference cooler another interesting aspect that I noticed while testing both coolers was the internal temperatures as you can see the temps spiked up to about 50 C with the G 12 compared to 40 C with the reference cooler and I think I might have the justification for that you see I had the 140 millimeter radiator mounted at the front as an intake and given the thickness of the rad plus the intake times drawing hot air into the case it was just a matter of time for the temperatures to spike up inside the case come to set up where you don't have any radiators in the front and just a stock cooler from Nvidia once again these results may vary depending on where you decide to mount the radiator inside your case provided you have the room to mount one in the first place now let's take a listen to how they sound so guys the GPU is installed inside the salad days 800 at the side panels closed so it's a more real world scenario that we're looking at right now and the microphone is right above frames right here and let's take a listen to how it sounds during idle so guys I've swapped out the NTSC g12 bracket and have installed the founders edition cooler I've also reapplied thrown paste to give you a sort of an apples-to-apples comparison so in terms of air flow I did replace the radiator fans I did remove the radiator in the front and I replaced it with the NCHC and that came with the radiator so we have fun intake just like before so let's take a look at how the system sounds under aisle so conclusion time this was my first experience tearing down an entire GPU and sticking in an aftermarket cooling solution on top of the core in this case I used the crack in G 12 and the X 42 cooler it was definitely interesting I had a few hiccups obviously the first one was the case restrictions that I had I tried mounting this on the s340 it didn't work out so I had to choose the silent base 800 which is a much bigger case so make sure you have proper room to accommodate the radiator in fact this whole setup because it's definitely a little intriguing the next thing to consider is the cost associated when you try to approach the solution because I'll be it it is not cheap it's definitely expensive for me at least it would cost around $160 as an add-on so I would highly recommend picking up an aftermarket custom card from brands like EVGA ACX gigabyte you name it also there are other things to consider like cable management because pump connectors fan connectors they all require some sort of skills to make it look non-existent especially inside a case if you have a tempered glass or window I also had to sacrifice my front I Oh connectors because the MSI board that I tested this whole setup with came with two USB 2.0 headers inside the motherboard one was for the X 62 cooler the CPU and the other one was for the X 42 cooler for the GPU and so you need to keep in mind make sure you have proper USB 2.0 headers or enough USB 2.0 headers to incorporate Funai oh and two pumps especially when you're using the NZXT series I'm not really sure what the deal is with other AIO coolers but you need to seriously consider this as a challenge or find a workaround to this so there you have it I want to hear your thoughts about the NCC Kraken g12 and is it even worth spending $160 or even less depending on which AI of solution you choose to liquid cool your GPU if it's running superhot let me know in the comments down below I'm a bore with how it connects thank you so much for watching and we'll see you in the next one
