hey everyone so we're in the process of building a hybrid RX 480 the idea here is to somewhat replicate the approach that we took to our hybrid GT X 1080 and that is hopefully to stick liquid on here now we put one of these on the GTX 1080 around launch day this is an ASA tech cooler and it's got an extruded there's a brand new and obviously extruded piece of copper here that helps GP cool and I'll explain that more in a second before getting to this content all this is brought to you by Origin PC and a new origin Chronos gaming PC which is customizable upgradable and now shipping with the RX 480 okay so this copper extrusion on the cold plate this is actually very important and is part just part of why the EVGA version of hybrid cards performs sometimes 10 to 20 degrees Celsius cooler than competitors that use a flat cold plate and this is not a liquid cooler but the idea is the same when there's a flat cold plate like this one and not an extrusion liquid coolers are actually considerably worse with GPUs and we explain this in some of our content in the past a lot of it has to do with curvature of the surface and things like that but we won't go into that too much here so I put one of these on the 1080 it improved the thermals more than a hundred percent as a percent difference value down to something like 18 degrees Celsius delta T from we're at near 60 Celsius with the original cooler so it was a big deal and it allowed us to get about next 100 megahertz out of the clock but we were limited by V bios at that point and it was still worth doing so we're doing that here I've taken this apart part one shows the teardown if you're curious how this card pulls apart it goes back together something like this a very very simple design exceedingly trivial to take apart and that's pretty much all there is to it then there's a shroud somewhere the shroud just goes back on like that this is a completely new PCB the existing products out there do not necessarily work with it the mounting points these are the mounting points that we care about these are very similar to the r9 380 and the 370 cards and as you can see this goes on the back under the plate so the mounting points are similar but they're not the same and that means things might not work and also the Z height of this GP if you can get a angle of that the Z height vertically is only 1.5 millimeters and it used to be one point nine millimeters so I think we'll be good and hopefully won't need a shim but we'll find out very soon the holes are almost lining up so we might be able to make that work let's look at some of the other stuff here is this does it tiny thing yeah so you remember I was talking about flat plates versus extruded ones this is a this is what a flat one looks like that looks like it might might barely work with this one on the bottom left what do we need next I need to make sure this can mount to the thing thermal paste Adam Savage was just talking about this in one of their videos untested which is a channel I really like forget what he called it I maybe Nolan laying out all of your parts like this definitely helpful oh I see that's where the thermal pads go I guess let's make sure before I start sticking that on let's make sure it'll actually work attempted to remove this plate and put the EVGA one on there but don't worry about that later okay so I think all the screws will line up with the back plate so that's good too now we just have to see if the screws will line up with the pomp and if the pump will make contact to the surface okay all this effort was just to see if we could get the the pump to mount to the the mounting points on this rx 480 which are different from what it's technically specified for per the instructions I think we're okay I think we just have to install this properly now now that we know it fits so I'm going to take this all apart and get it together correctly let me just see out of curiosity if we wanted to connect these could we how many measures let me measure something this is just digital calipers 47.62 let's lock that where it is oh that looks very good any bolts this is the same same mounting then the question is do we want to go through the pain because I think it drains the liquid out let me make a phone call the ASA Tech client Rob teller hey I'm building an Rx for a dihybrid I have a question for you is it possible realistically to replace the cold plate on the the Arctic coin one with the EVGA one or will fluid come out that's fine some special oh my god I just kill the entire team I could we could have them make you a couple AMG like flat ones and then extrude one okay cool well for now we'll do this piece okay so after a quick call to a Rob teller today's attack we found out that even though these it probably you could actually put that on there realistically it's not feasible because liquid will leak and we have no good way to seal that and prevent any liquid from leaking out so that's no good we're not going to switch this this will not mount to the RX 480 because it's just not the right size so I'm just I'm going to get this out of the way we're not even going to come close to using that this time but we're going to try and do something with it in the future maybe adapt the adapt the cold plate or something because this cold plate is still built for GPUs not CPUs we should still see good performance and that's the main concern is those CPU CLC cold plates have a different curvature basically just because the way the CPU hotspots line up with the cold plate this will work so let's go ahead and put the thermal pads on here for vram modules like this lets get contact I like that this is well designed I don't think we want this on there this is a thermal pad from the original which thermal paste we want to use here these instructions are actually pretty damn good they do make recommendations for how much to use which is always nice they're recommending half the compound which seems like an awful lot but we'll see so half the compound would be about here that's about half and it is okay to bleed over some on the GPU it's not as sensitive as a CPU when it comes to that sort of stuff now which way do we need the tubes oriented I need to know that - that puts that in the top right which would have us like this okay that makes a lot of sense actually that won't collide with the vram be nice favorite catch on the other side other than the CLC assist yeah I was thinking about that there's a way to do that yeah put it uh so it's like on the corner but not going to fall off hold it there is it aligned with this screw time apply pressure so push it back yeah alright I think we're good right so I had to recruit Andrew to help get two of these on because and also a clamp because the thermal paste is slippery for one and also these Springs are very high tension and also it's difficult to align the screw with the liquid cooler so we're good now though these are all on and off I can remove this clamp now that thermal paste by the way the recommended amount of thermal paste was was good they recommended to half that tube turned out to be just about perfect because of the way it spread so easily it's a very is not very viscous there's some some thermal paste that's more viscous than others especially if it's diamond compound and that is not the issue we had here so because these are spring loaded or spring tensioned screws they will stop you pretty naturally once the screws are about as tight as they should be and that's it's it's a case of a monkey Titanic real tight once you start getting free spins like this check this out see how we're getting a spin now that would of course strip the screw if I kept doing that you can apply more force and torque it down get a couple more turns in there but that's not what you should be doing there's decent contact it looks like there needs looks like it may actually need to be pulled down a little on this side which I can do by tightening the screws some more can you see a it's on this side in there it looks like it's almost missing in contact so even if I apply more pressure here I don't contact a little better okay I could probably tighten the screws some more see how that is fully fastened let's try it contact looks okay over the center of the GPU I'm looking at the borders and I'm seeing it like a hair's width gap at the border between the copper and the silicon see if you can try and get that see if this board's flexing well that is definitely see it I see if this cracking kit has a copper shim know about this no shims though I call Rob again so there's like contact completely to the silicon but not completely to the top left edge of the substrate I mean as it should be the silicon should be a little bit fuller than the substrate okay cool I'll put the vrm heatsink on and we'll be able to plug it in tonight probably I was considering streaming earlier but maybe for the next one but a cooler I'm going to finish this up thanks for the info yep see it we're making full contact with the silicon with the cold place so the cold plate itself is touching the silicon completely we're good there the border of the substrate which is that got that sort of metal plate on top of it there's not 100% contact specifically in this corner but we think that's okay and I was speaking to Rob from ASA tech who thinks that's okay because it's not it's not the part that gets hot it's not the silicon so I think we're okay that is the one thing to note we may look at that for performance but otherwise everything looks decent I've backed off the tightness of the screws a little bit giving that information because we're still making 100% contact with the silicon so there's no reason to over stress the socket and cause the PCB to warp so at this point all we've got to do is figure out the VRM aspect of this so I've got vrm fans they've given me this is ooh that could actually fit but it'd be a bit silly okay so they're saying to put this like up here and then just tilt it so that it cools the vram or another vram the vrm these components I need a cooled I think we're going to use this stuff for the vram with that thermal adhesive see how those look oh cool that's already got adhesive on it I just have to peel it so can we stick this to these old man that is actually really neat I like that the same goes for these things as it will go for the vrm heat sinks that I'll apply in a moment which is make sure there's no contact to any electrical components or it or it could short something there's one module in there I'm not gonna be able to access that kind of sucks I'm not sure the best way to deal with that that one will get hot so these will go there this will mount on a pole up here and be positioned like that so this is super ghetto a version of a vrm cooler will pivot this on that pole to cool the BRM components and then we're going to put these on top of some of those vrm components now let's see what do we want it on here guess all yeah because the way the fins stick up the air that gets pushed down will go through there and dissipate the heat so these will go on each one of these that's a freaking lot of this eleven twelve all right let's try this let's get these applied is this yes this is actually a thermal pad that's pretty cool I like that this is what my what was this I think this is like six or seven dollars on Amazon these things and that's pretty that's pretty damico I like this this last one I'd love to get this on there but it's obviously just not going to happen now that's already cut it in half okay so next I'll shoot there's another one too it'd be kind of janky so the question is do we want to cover half of this with one of these yeah this will be fine what else were we cooling AMD really intense cooling in this area so that's the next most important we're going to have to use this stuff this is thermal adhesive it's basically glue we're going to use that to mount these these are VRM aluminum finned heat sinks we've got a lot of them with this generic kit for the the hybrid three Exelero cooler and on a mount one of these like this on every one of these hotter components that's okay so lesson learned that was a lot of adhesive we don't need that much for the next one we're going to do a lot of these this is a pretty freakin extreme mod to complaint a city builder gam City skylines nice okay all right so those are on now the next part of the process involves mounting a fan to a pole which we can stick through any one of these holes I'm going to attach these two yeah I think we have to let it cure we're going to let these BRM heatsinks cure overnight it takes about an hour for the thermal adhesive the cure I'm going to give it longer than that and we'll be good to go to test this thing all right so we let this cure overnight we're back now and I've made a few changes to the design while thinking about this letting this thing dry so first of all these are now cured they're good to go this is the the BRM cooling but I did have one thought and that is I would like to use both fans that were included with this actually two thoughts so I'm going to clamp this to the and this is a little a little crazy but we're going to clamp this to the expansion slot bar on our test bench and then this will be mounted like that and that'll push some extra air down to make sure we get the hot air we really don't want in there out of there and and get some more cool air into the VRM and to some of the components down here down the channel that do not have a heat sink on top of them so that's one change that will happen on the test bench and then the rest of this my thought here was we're going to mount this fan like that but I am NOT going to plug this into the GPU so we're not going to plug this into the video card we're actually going to plug it into the power supply and that'll give us an extra couple watts off the card when we're overclocking it so we'll talk about that more in part three but let's go ahead and install this then this pretty simple process we're going to just send the screw through here this goes on over the spot screw spot over here the hole all right cool so that's it that's what we got for the video card this will i'll pivot this based on how I feel about the thermals as is being tested we're not plugging into the GPU as I said so that means the VRM fan speeds will either not be reported or will be reported as astronomical numbers and the reality is it'll just be powered by the PSU so it should be a hundred percent power that'll help us with some of the overclocking attempts and then for acoustics I might I might plug it back in to the video card when we're taking acoustic measurements for the auto pre overclocked configuration but I'll let you guys know if we do that so that's it that's the RX for eighty hybrid check back for part three this thing will be in the bench and running soon if it still works and at that point we'll see we can overclock it further see if the thermals are better they certainly should be and I will look at acoustic properties and maybe throw an FPS chart in there with the new overclock settings so as always links the description below for more information thank you for
