today we're going to be looking at thermal paste spread and coverage on a thread Ripper IHS we have a cooler on here already so the plan is to walk through that this one's from the factory and so it has the factory installed thermal paste on it we also have silk screens to show you how the spread will be for different taste attack generation coolers which will cover most coolers on the market and then at the end of the video we'll be walking through installation of the cooler and the installation of the CP and the socket but first thing to go through is the compound spread and then we're also going to using our new prop that we've put together specifically for the purpose of scene where the dyes are covered and where the thermal mass covers versus something like a traditional die before we get into that this content is brought to you by the thermal take flow RGB closed-loop liquid cooler which is a three hundred sixty millimeter radiator plus three 120 fans that are RGB illuminated ether and we'll take it rain fans at that this is a 4.5 done a detect pump which is one of the faster pumps you can learn more at the link in the description below so the first thing we're going to do is dismount this cooler these install in a particular order they are numbered on the mounting bracket the mounting bracket comes from ASA packet is supplied with the thread Ripper CPUs and you can see that these two screws are closer together than these two and they are numbered one through four so two three one four and that order and orientation oh you know what before we just mount this let me show you something else I'm going to show you memory clearance because we have to go ahead to show all this stuff today and we can't can't show performance numbers I don't like unboxings I think they're useless so instead we're going to try and show you some useful things so here's a memory module I'm going to socket this over here in the closest possible spot there's a keep out zone on every motherboard and that means that the manufacturers need to make sure their products clear things so if you mount really any ace of that cooler of this size and form factor you'll clear even if we have the tubes more this way we would still clear I actually specifically change the bracket orientation on the cooler to make sure that the clearance was not an issue you have something like a kraken series or an EVGA CLC cooler they are a bit larger and they will start bumping into the larger heat spreaders on memory modules so be careful what you're using what motherboard you use how close it is between the memory socket and the CPU socket so that shows that it gets that out of the way so we're good on this particular unit but not everything will clear depending on the board and the CPU cooler they should they're supposed to it doesn't mean they will because some of this stuff is obviously maybe for thread Ripper let's let's remove this in reverse order so one two three four so that's the order we're going to go for removal I like to loosen these about 1/2 to 3/4 away and then I loosen them the rest of the way after that 2 1 and you are technically supposed to tighten them in the same order that you can probably do a bit better I'm just going to go opposite corners until it's loose alright so there we go let's go make sure I'm not going to impact what we see oh man that is this is my first time actually seeing that so you're seeing it with me ok so here's what we have this was installed from the factory this their own pace you can't get too much better than that normally for something like thread Ripper I'm thinking you might be able to get a bit better than that but we'll talk about that more in the review and we can I actually saw some data so here's our coverage now the question is and this is something we talked about a lot in the or at the event the question is how much does it matter that you're not covering the whole IHS clearly the cooler the thermal paste part is contacting there the rest the cooler we've got a little bit more space so let's see how much how much more we have exactly so out the edges we've got another just a rough quick measurement here got like another 10 millimeters you go so how much would that help us out here and I not get you most away cover that I'd get you like 3/4 covered if this whole thing had compound on it now it doesn't matter so here's what the inside of one of these looks like we've taken all of these apart that's important is to have the thermal paste contact and directly under your highest density of copper or your highest thermal mass and for this unit that's going to be right here this is the same coal plate you'll find in the EVG vga c LC coolers you'll find this in the NZXT cracking coolers in Corsairs h 100 IV 2 of course there's h 115 i and about 60% of the coolers on the market that are CL CS so this is what you'll find in all of those same thing it comes from the same supplier this is an older cold plate this one is from a much older cooler master sidon cooler and even with these although the copper circle of the bottom the cold plate is larger the actual density of microphones is about the same on that so these are good standings for what you can expect for where your thermal mass will be on a cooler you can look at it here we've got the again this is the exact same as the thermal take one for the most part that we've got so you kind of line them up this is what your contact area looks like depending on orientation of the cooler and either the fins are vertical or they're horizontal and there's actually an ideal way to do it ideally you have it this way now unfortunately there's not a great way to know if you're oriented that way or not without opening the thing although I guess actually for future reference let's see now they are actually they are a bit different on these on today okay well anyway theoretically this would be better than the inverse than that but yes that's our contact area not fantastic but what actually matters is as we'll see what this thing here and here's here's your unboxing a and B yes here is your media gift we actually put it to real work so this thing theoretically is a non-functional Rison cpu an engineering sample it's a little bit different for than the production samples we drew on it so this thing thanks to some measurements we found online hours video thanks to known information about Rison which is the same dyes just this is more of them we're able to trace things out and figure out where the dyes are through the IHS without deleting it and each dye is eight point eight seven millimeters by 22 point oh one millimeters as I understand it today something like 195 squared I think so each of these is eight point eight seven by twenty two point oh one roughly and they are offset thanks to their bowers video we were able to figure this out we actually just superimposed the image on the computer with the CPU and we were able to trace things out so the offset is something like twelve point five millimeters inward this way for the dye so from the the long way it's twelve point five inward and then it's about 16 to sixteen point one five up or down in this case and that's where your four dyes are so what we care about is what's the coverage over these does it cover the dyes and this is what we've been saying the theory of but we haven't known in practice and we won't be able to show you the data until launch day but the theory is that as long as this cold plate covers where the dyes are you should be okay you don't need to contact the whole IHS to cool now will it be better probably you'll probably have a bit more efficient thermal transfer if you contact all this surface area that's spreading the heat hence the name IHS and conduct it through your cold plate but you don't have to what you really care about is the hot spots let's just take a look at that right now that is awfully close so there's your hot spots they are in fact covered so yeah if the theory is correct the theory being that all you need to do is cover the dyes then you are transferring heat into the cold plate and therefore into the cooler the part where it gets a little tricky is these outer edges and only two of these are active mind you these outer edges are not covered by the micro fins they're just covered by the cold blade so you're not going to be the most efficient transfer that means there's room for potential improvement if cooler manufacturers want to come in here and make a better cold plate and it looks like a few of them have but not all of them so two of these are active I have been informed by Andy and this is public information that we've already published that the same two dyes will be active on every thread Ripper CPU so let's just say it's these two those two will be the same it will always be those two on every CPU from what we've been told and these two are silicon substrate more or less spacers we'll call them that just help with mechanical mounting pressure so it does kind of start looking like epic at that point so two of them are contacted but yeah that's what it looks like next thing we can do is start showing different we've got over here actually a whole stack of silk screens so let's kind of bring that over here this is what we use to make sure our testing is consistent from one cooler cold plate to another so this is an EVGA c LC but it's the same it's a Gen 4.5 cold plate and then we've also got for example bag of EVGA s 4.5 cold plates these are silk screens by the way if that wasn't clear so to apply these video on it we lock this to the bottom of the cold plate do a syringe of thermal paste there and then use like a spudger to spread it and then you can you can get perfect contact just like it's out of the factory so four point five is there we have Gen 5 which is the current newest the Gen 6 is on the way and we have gen for Gen 4 bit older now Gen fives and stuff like the Kraken xxq stories execute to 40 to 50 to 60 to and the coolers where the pumps protrude straight out of the pump block as opposed to hanging off the side like these so when you see them the tubes rather not pumps the tube sticking straight out of the block like some of the coarser units the age 100 IV to I believe does it that's a Gen 5 so let's just go ahead and take a John 5 cold plate since we know that there's the most common and if you were to apply it's probably gonna be about the same spread is it yeah it's about the same spread so gen-5 will cover the same area as what we're seeing with thermal takes which is a gen four point five flow so let's look at this over here give you an idea of coverage without hopefully ruining our masterpiece I trying to get a cleaner one okay here's not useful we've not doing this so your coverage it's really not fantastic the Z is the Z dead center Z is dead center looking at our grid so let's just go ahead and orient with the Z somewhere around there you know work with me obviously actually this is a dry erase marker so I can't but somewhere around there so one thing to point out here is that the center of the thermal mass of the cold plate is actually situated over nothing so the normally hottest spot of the CPU is going to probably be around the middle of the cold plate but because this is for dyes that are segmented with nothing and dead center the coolers actually sitting over that dead center area and that's not even a hot spot so your most efficient point of thermal transfer and dissipation is not really going to be leveraged with these coolers on these CPUs it is not necessarily a fault of the cooler design or of the CPU design it's just a byproduct of the to not necessarily being ideal for each other so no one's really at fault here you could just do bit better though so the hotspots will be on the dies so top left bottom right or bottom left top right depending on the which ones are active those will be your two hotspots and those are at the perimeter or the periphery of the cooler the cold plate so they're actually going to be less efficiently cooled than if your cooling is on the dead center like a traditional single die CPU for desktop so that's something to point out how much it matters again we'll test it I keep saying that but it's important to say not to jump to any conclusions right now until we can test it and publish the data I mean again you're looking at the cold plate making contact and covering the dyes just barely just like a millimeter barely covering them the thermal compound won't make full contact you might want to go in there and add some more if you if you feel so inclined I might improve your thermal contact so get a Gen 4 is Gen 4 not a big difference between these in terms of the contact area so I'm thinking it's going to be about the same yeah got the same so if we can kind of get this on camera the silkscreen is imperfect but the circle for the dome place is pretty close to it it's roughly around there so what you're seeing is is this as a pointer you're seeing as the dye right here feeds out to this area so this is the border horizontally and vertically so we're not covering with the thermal compound but we'll cover it with the cold bleed once again how much that matters we'll find out soon but we don't know today or can't tell you today so as you can see the only point of concern here well aside from not having full IHS contacts which may or may not be irrelevant as we'll learn in the review hopefully the main point of concern is where these screw holes are you're going to have some hot spots because contact is not perfect these are indented a bit so you're not getting copper contact you'll get a screw contact and if you go through it and add more thermal paste you'll at least have a thermal interface there otherwise this is actually indented and there will be a small pocket of air and a hot spot on the particular part of the dye that corresponds to the hole so we can kind of lift this up a bit and you'll see we can see down to part of the dye so it is imperfect there will be some slight hot spots we would encourage at least adding some thermal paste where the screw holes are so that you can get transfer up somewhat to the cold plate but just be aware of that and we can't really comment on how performances is until Waze tested it properly so all that in mind may be an issue may not be an issue and then Jen 4.5 we've kind of ready showdown will take cooler so that's what we're looking at for coverage let's um let's take the threader for CPU out of the motherboard and walk you through that process without dropping the media sample off the table so for this again let me just kind of wrap this up we'll talk more about this coverage in the future it's coming but not today in the very least you have an idea of what to expect for a Sutekh cooler coverage on these they will clearly not cover the entire area and actually let's just go ahead and kind of line this up to show you good enough it's not being tested right now okay good enough so yeah let's let's like just go ahead and do this one more time there you go there's your coverage plain and simple within spare ly centered more or less so there's a lot of room here for cooler manufacturers to do something interesting with thread Ripper in all theory this should be fine oh do the air quotes there it should be acceptable that doesn't mean it'll be the best doesn't mean it'll be optimal but it should work because you are in fact covering the dyes so we should be good in that regard but it doesn't mean it's optimal so to release this thing I said we'd show how this works there are three Torx screws I think they are TR 22 one point 5 Newton meter torque Torx wrench included torque wrench that is torques to be clear to remove the thing you go three to one to add it there to close it rather you go one two three and these are they've won two three vrm oriented up one two three and because it's a torque wrench that means when you close it how this demo it for you when we completely bottomed out the Tork will get it click it comes as I'll fight you so once you hit that you can't go any further this is actually really good on AMD's part I am appreciative that they have made it plain and simple exactly how much force you can apply to these things so if you do lose this wrench that comes with it it's 1 point 5 Newton meters or if you prefer that's 13.3 inch pounds and I think a TR 20 double-check me but I think that's what it is so we remove that you get blue latches under here make some room it's a blue latches apply light upward force same process we're adding the thin Springs forward pull the orange tab comes out there's your socket this orange housing is meant to stay on the CPU do not remove it do not throw it away you'll need it so that exposes the pins and more or less gives us an idea of how everything goes together now if you want to install it to you basically would well where's our socket cover I can show you exactly how it goes so here's how its ships ships with one of these covering the LGA socket something like that just make sure alot pinching pins ok you should keep that in case you ever need to close it up again to protect it and for RMA purposes you will need it and then this slides in or out through there so when you get the thin it will look like this and then you loosen them three-two-one Springs forward it'll be like that you release this and then this do not push on the back you'll break something pull this tab up here slide it out and then at that point you can insert and socket the thread Ripper CPU like this it just it slides right in orange tabs should meet the black at the bottom and then you remove your socket cover very last to protect it till the last moment push down if your socket correctly which we are and it sockets and then you go one two three and close it so that's what it looks like that's the thread Ripper CPU rapid installation but more focus again was on this aspect of things and if we were to mount a bunch of coolers to this all the attack ones will look the same so what you're interested in this is what does it look like when you get some special like knock to a cooler they've got those new air coolers coming and you mount one of those two here with the larger coldplay well it should look like the whole thing is covered and theoretically that's better in practice we'll try to find out a be testing with coolers like that you need two different cold blades we'll try to get something arranged but the very least we know that a stack coolers will cover that die area you will not get full IHS contact you don't necessarily need it but it's probably nice to have stay tuned for our review that will show you how much if at all it actually matters compared to something with fuller contact and I think we have some plans on how to simulate that in a way that is realistic enough to give you an idea of what one of these would look like if it had full contact because we've worked with these enough tone them down enough to have the resource to do so so that is the CPU installation and walkthrough of the cold plate cooler installation all that stuff if you want to install a cooler it's got the four screws just like I said a moment ago you just socket it down one two three four and you're done make sure the closer ones are at the top near the prm's and for today this is all we can show you so Andy has approved that we can show you the CPU installation and we can show you cooler installation and as an addendum of cooler installation we showed you cooler coverage and contact area so thank you for watching as always you can go to patreon.com/scishow and excellence comes out directly subscribe for more to make sure you don't miss our
