everyone today we're taking apart one of the most expensive r-tx 28 ET eyes on the market and that is the RT x 2080 TI f TW 3 by EVGA following up their long-standing FTW three lineup of about one generation but this one is particularly interesting because it's quite a bit different from the past FCW 3s the face plate has had a change for better or worse today on how you feel about that it's a lot fatter and the PCB space is pretty densely populated as you'll see when we take this apart separately we have another video coming up of a PCB analysis of this board by build Zoid so make sure you subscribe to catch that if you haven't already subscribed so then I think it's about 1,300 plus dollars for this card let's take it apart and see why it's so expensive before that this video is brought to you by thermal grizzly and their high-end thermal compounds thermal grizzly makes cryo not paste for high thermal performance and conductivity without being electrically conductive so you don't have to worry about shorting components Crona is particularly good for replacing stock GPU pastes as cryo knot is a non curing compound learn more at the link in the description below so for the board layout pretty straightforward three fan cooler I think there is an IC X version of one of these but I don't know if this is one of them will will find out though as we get into it and then it's got a BIOS which for a normal and OC mode it does default into normal mode and will just flip that over so you can read the text on it normal OC they even oriented it correctly so that in a normal case you can read it that's kind of small attention to detail this over here 12 volt GRB header so that corresponds to the pin out for obviously an RGB header so you plug this into a system right there and synchronize the LEDs with other strips of LEDs in your case if you wanted to if that's the kind of thing you're into and then also over there there's an auxiliary auxiliary fan plug which is right around there it's a four pin PWM plug so you can attach a fan to it and then slave that fan to the GPU if you wanted to increase or decrease the speed based on the video cards temperatures the cooler is obviously very fat in a large part of the cost of high-end cards like this there's about a 2.75 to three slits a full three slot this is yeah this is basically a full three slot card so it's 2.75 for the thickness of the shroud and the cooler and then once you look at the actual slot requirement it is a three slot card so a very large card some fat heat pipes in there as well we'll measure those once we get into it and tear it down so you can see five on this side and then there might be more and we'll look into that and then for the power there are two eight pin connectors so let's take it apart this one's an EVGA device it's pretty easy to take apart so first of all we can remove the screw that's near the tamper seal but it is not a warranty void if remove its sticker so EVGA uses that to figure out if they need to replace the paste or not on a card let's come back into be recertified or something like that but they don't void your warranty as they've told us anyway if you stab through that sticker and we've got four of the spring tension screws actually these ones I'm taking out now don't even need to come out yet the way ebj does their mounting now it's actually really simple so you can just remove these four okay that should do it yep so you remember those four on these EVGA cards now and you can free the entire cooler which is actually pretty nice from an ease of installation standpoint you see it's completely free right now the thing holding us back it's gonna be three cables there so three fan cables and then an LED cable on the other side so we need to disconnect those you have a piece of a throne pad here so that's how easy it is take those off these days four screws and once we're in there is your that piece of throne pad goes when we're ready to put that back let's start with the cooler and then we'll go to the base plate cuz that's pretty interesting to some of the cooler they are using several heat pipes of varying sizes which we can measure these are about ten millimeter pipes these flat ones right here there's larger ones are see ten millimeters up towards this side of the device and then that's gonna be ten that's an eight eight millimeter pipe on that one so eight and ten for the most part with a couple of smaller ones in here and if you look at them there's actually a lot of a lot going on so through the board left side of the heatsink where the vrm is situated we've got one heat pipe going straight through the cold plate this doesn't contact the GPU ever and I don't believe it comes into contact with the memory no definitely well I'm gonna go with them now on that doesn't come into contact with the memory there's actually kind of obvious because that pipe is situated under the two screw holes and those two screw holes are gonna be where it mounts to the no-go the keep out zone for SM DS so that doesn't cover anything it just kind of goes into the plate and might provide some additional sinking power what really matters is the coverage of heat pipes over the GPU itself and so for that they've got this fat one this ten mil goes through there that continues through the vrm side of the heatsink there's this smaller pipe which looks like it is this one so that goes right through the core as well this smaller pipe goes through the proto of the core and this one does not and then for the rest that's small heat pipe actually that one continues where does this one go this one goes through the other edge of the core and that continues through most of the heat sink as well terminating right here whereas the others terminate over here so a bit of a difference on where those heat pipes end for the fin stack so this has done a few different ways EVGA has got three types of fins they're using primarily they have the l-shaped fins which are right here so you can find these on a lot of cards where typically you want to provide more surface area to something for example providing some surface area - the heat pipes so that allows these to contact the fins Foley they are typically soldered to the fins and that allows for better heat transfer into the fins so that as these heat pipes these if you don't know these use a capillary action and phase change so there's a liquid in there it goes through a phase change as it hits the hot area the core so phase change from liquid to a gas you lose a lot of energy there or you lose a lot of heat there in the form of energy in that phase change process and then as it phase changes into a gas it will sort of translate up this heat pipe to the end where it then reconned ences at the end and and will trickle back down through capillary action at which point it can be recycled so connecting the heat pipe to these l-shaped spins gives a bit more surface area and that heat can better dissipate into the large aluminum fin stack from the cabra heat pipe which makes better overall use of the materials on the surface there are also the flat 90-degree fins where there's no bend at all these are useful for allowing more airflow through the fins so you see those over on this side of the board primarily where really all that all it's doing is allowing the air to go through and hit the baseplate on the board which is aligned right there so it hits the baseplate provide some cooling over some of the MOSFETs over here or sorry the inductors over here and then the the primary inductor line and MOSFETs are contacting these sort of 45 degree angle fins and those allow air to get through while still providing some additional contact area once it squishes into a thermal pad so that's the strategy behind the three types of fins you see here and then the this stuff in the middle is just a brace where it's all connected there's sort of inter woven so they come together if you take it apart they almost count apart like a zipper and that's that covers those these are are color-coded primarily for internal use I think so they've got some markings on the sides of the fan headers not something you need to worry about and then there's your LED cable down there as for the fan so the fan down in there is a power logic fan we actually interviewed them previously or while we we spoke with them at Computex in Taiwan this year and the way I know it's parrot logic fan is because the sticker down there says para logic and whether or not the camera can see it it's a it's para logic fan it is a brushless DC motor of course and I don't know any of the other specs on it but if you were curious of what the model number is let me take this away from the camera the model number is C 12 volts is 0.55 amps so that's useful model is PLD 0 9 - 2 0 s 1 2 H if you wanted to look one up to buy or something like that I think that covers most of the cooler sort of disassembling it I guess there's one more thing talk about these these holes through here so this started with icx on EVGA cards following a CX and the idea is just to allow some more air to flow through the internals of the fin stack and escape out on this side of the card of the fin stack so a bit more air flow changes the surface area characteristics as well and presumably helps in theory it helps is just that a theory isn't always reality depending on how small of a change it is and then here's the base plate so for this one you've got the sort of what is this this aluminum that might be a steel might be a steel material but it is not a shiny material so that's good it's more of a matte finish so anyway this is a metal service that raises off of the aluminum it might be a steel we'll check with them for the review and update as necessary so anyway this comes into contact with the fin stack with those 45 degree angle fins you've got your inductor line here and then the MOSFETs are under this part of the plate so they've got good good thermal contact to the plate via thermal pad which then conducts into the fin stack and the capacitor banks not even really covered with any direct contact it's just getting pure airflow which is plenty for caps because they just need to stay under like 100 degrees or so 105 or 85 to the pound the cap spec but typically 105 C is definitely where you want to be below so those are fine with just airflow and the rest of the plate is smooth aluminum brushed aluminum finish so they do not have the pin fins as they call them on this they instead went with a fatter aluminum heatsink rather than taking up more area with the pin fins so at this point let's remove the base plate to look at the rest of this and to do that we need to take off those take out the screws in the back that I started on earlier okay that's a lot of screws there are three movies three more screws to take out hiding in here so for this thing you can see that the base plate here has this metal sheet that comes up and that connects to the expansion slot right there and then three screws in there from the backside and that holds down the plate onto the PCB so we still need to take those out so this is where it gets a little interesting this one I already took apart for photos for build Zoid so we already have that on the way and that means I was prepared for what you're gonna see it's a bit funny a bit different we've done some baseline thermals on this already but need to attach thermocouples to the MOSFETs like normally for more in-depth testing that becomes a bit tricky with this one but fortunately I already know what this compound is so I can get more of it easily and replace it as necessary because what you're seeing here rather than the usual thermal pad for a connection between the plate and the inductors EVGA is using this stuff this is a you can see it's kind of sticky but not not liquidy like thermal paste this is called thermal putty it's a little under it's like 1.5 watts per meter Kelvin something like that we have the datasheet for it it's all in Chinese but we have the datasheet for it like understand the numbers on it so we're gonna try and get some of the stuff just for future a be testing cause it'd be kind of interesting so that's a bit different and then also interesting is although not that interesting these days is the use of a heat pipe under this thermal pad not that uncommon but there you go just not a copper heat pipe there and that connects with the MOSFETs so that provides some additional cooling capabilities in theory to allow the MOSFETs to communicate their energy into the fin stack more efficiently so we have some of the thermal putty spill over here I already have baseline thermals and then we'll run more with our thermocouples attached later and replace as necessary for the MOSFETs we're ready we're setting all this information have already sent all this information to build Zoid so I'm going to save that for him but we do have our actually kind of sweet new magnifying glass that Intel sent for their architecture event we've been making real use of it this is the most useful media clips we've gotten in a while and some of the parts on here that builds I will be walking you through the significance of and again subscribe if you want to catch that if you already know that what they do we have a up9 5 1 2 P over here and on semi four five four nine one the MOSFETs are also on semi those are 31 70s looks like everywhere and these MOSFETs over here on the left side of the VR I'm kind of unique these are 31 70s as well there's the memory VR M so this they made this really easy for us you can see on this one that these are 22 inductors these all correspond with V core v RM so you can almost draw a line here at the screwdriver for the memory v RM where you've got another three phases up there and then you have if we're just counting inductors you've got it two four six eight ten and then there's more over here so another two four six in addition to that and build Zoids gonna walk through the layout of this somewhat complex and interesting vrm so I'm gonna leave that part to him but on the back side we have a couple more components as well and the very least it allows this the CRM design allows for spreading out the vrm heat over a very large area basically the entire PCB which ultimately means more efficiency and getting rid of that heat all right so an EVGA style throne pads all over the back and actually putting the backplate to use so if you have EVGA cards you know the back plates get pretty hot it's actually good thing because it means it's doing what it's supposed to do you want metal things to get hot because it means it's pulling heat away from things that you don't want to be hot so those have their old pads for back of the socket for the memory right there and then for the whole back of the primary v core v RM + vm v RM and then there are a couple more components on here I'll walk you through that again build Zords gonna talk in detail on but another you p95 12p u p7 five six one zero another one of them and another one of them it's like three of those something like that or more and that covers most of the board components so we'll leave the rest of that analysis to build Zoids end well I took the cooler analysis for you so that's EVGA is FCW 3 card couple more things on here there is a 1 million ountry sister over here near the RGB cables or pin out there's a 5,000,000 unresisted down here and then there's a another 5 million ohms shunt resistor over here and then one more 5 milli ohm shunt resistor on the back and that one is over here which those positions are important if you wanted to do a shunt mod on this and short them as for higher power limits and overclocking or something one of those will correspond to the PCIe slot just take a DMM and do a resistance a continuity check like the 8-pin 12-volt lines to see which shunt resistors correspond to the 12-volt pins because that's what you want to pull in you want to pull in more power through the PCU slot that's bad so that'd be how you do that but that covers EVGA FTW three we'll have a full review at some point we have built joins analysis coming up as well so again subscribe for
