we replaced one of the AMD Rison APU heat sinks the integrated heat spreader with a copper one from rocket coal technically the one I just held up the and the included one is also covered but it's a nickel plated copper and it has a bit less surface area than what we have here this is basically the same product as when we reviewed the Intel one from Rocket cool except obviously larger and custom-made for the risin AP use today we're going to look and see if the copper custom IHS actually does anything thermally and whether it's worth it or not before that this is brought to you by the correct pronunciation of Jif sponsored by Nvidia's GeForce experience and MSI's 1080 Jamie and X we use g4s experiences shadowplay to capture J and play footage of popular James like Grand Theft Auto 5 and pop G fun fact the G stands for jiff learn more at the link in the description below to grab shadowplay or the msi gtx 1080 Jamie necks the major difference with the Rocket cool intel heatsink that we tested previously was that it has slightly more surface area than the stock Intel IHS and that gave it a bit of an advantage for cooling this one isn't as much that way and the n' rise and IH asses are basically perfectly flat on the top they don't have the chamfered edges like the intel ones do and that's kind of where rocky cool is able to gain some of their service area with the Intel copper heatsink that they made again they're both copper heat sinks IHS is it's just that one is nickel plated and one's not not a huge difference other than a non nickel plated one is really hard to scrub liquid metal off of but if you're not doing what we do that's pretty much an irrelevant point when you are doing any kind of deleting what we've learned from Intel and now from AMD is that the thermal performance difference is not just from removing the stock Tim and replacing it with liquid metal we use thermal grisly conduct or not but also removing the silicone adhesive that sits between the IHS and the substrate that creates a bit of an air gap between the die and IHS and they fill it with their own pace so it's not like it's just air but having that much extra thrown pace means that you have that much more material to go through the transfer your heat to the copper which is the IHS and eventually to your actual heatsink that's mounted to it have any kind of interface is suboptimal ultimately we need them to fill imperfections and services to account for manufacturing tolerance issues like again with the air gaps that are created from silicone adhesive on both the AP US and Intel CPUs and so we needed a thermal interface but because we're individual users and we're willing to spend the while take the risk and spend a bit of time you can improve cooling overall by deleting this something we already showed with the our 320 200 G previously where we overclocked it kind of lightly the point of the overclock wasn't to push it far but was to generate a lot of heat which we did and then tested it and saw a significant improvement more than 10 degrees in a lot of cases this time we're doing the same thing except we're taking two new tests here one is with the copper IHS from rocket cool the raw copper we'll call IHS and the other one is with silicon adhesive removed completely versus not removed so that we can see how much of the difference is a result of the IHS change and how much is a difference as a result of the silicone adhesive removal so we're testing methodology as always go to the link in the description below for the article where we'll talk more about how this was tested what software was used all those questions you have questions go to the article what we're testing today is a few main things that you need to pay attention to one is stock CPU with silicone adhesive unmodified and with thermal paste from Andy complete factory stock the next one stock CPU with a stock IHS from AMD and with liquid metal thermal grizzly conductor not in this case the next one stock CB with stock IHS liquid metal and silicone adhesive removed and then finally the copper IHS from rocket cool without any silicone adhesive so it's that pretty much give us a full sweep of everything let's go through the performance tests so getting straight to it we see the rocket cool copper IHS is the highest performer on the chart exiting error margins and plotting a two degree improvement over the next best which is the stock IHS with the silicone adhesive completely removed that marked us at twenty eight point one degrees celsius over ambient forty died both of these tests used thermal grisly conduct or not which will link below and had the silicone adhesive completely cleaned off of the substrate and the IHS the next test is our deleted thermal result with silicone adhesive still present on the substrate but with liquid metal applied and obviously a deleted processor that had us @ 32.6 degrees over ambient showing a four degree improvement to 28.1 where we ran the same test but without the silicone adhesive with it completely cleaned off the reduction in the gap between the IHS and dye is responsible for this performance uplift note that this is outside of error margins for reference we previously measured the stock 2200 G with stock Tim and adhesive at 47 degrees Celsius over ambient although it was overclocked so not that stock and that marked minimally a 14 degree reduction to our D lid with liquid metal deleting and painstakingly removing all of the adhesive got us another couple of degrees the rocket cool IHS does offer benefits that exit error margins and are measurable and it's to the tune of about 2 degrees Celsius not world rending but certainly measurable so going back to the coffee lake 1 then if you didn't see it we put this on the 8700 K and it was 20 bucks our conclusion with this was that we observed about a four to five degree improvement with the custom rocket cool IHS and for that side of things we said basically it's 20 bucks this isn't going to change the game a lot for you in terms of overclocking but for a piece of copper it's pretty damn impressive performance uplift to have an extra 4 degrees of headroom when this is what you're changing you'd be hard-pressed to find 4 degree differences between a lot of the liquid coolers on the market so that alone was impressive but again it's not something that you purchase looking to increase your overclock in significant ways it's really it's a it's a way to give yourself an excuse to have something fun to do with computers for an afternoon that was our conclusion it was this is a really fun Saturday project for an impulse purchase price of 20 bucks so you can't go to wrong with it and as long as you're not expecting a ton it's a fun project it makes your CPU more unique and yes you do get a couple of extra degrees which if you were to try and stretch out the argument you could say that that allows you to run your fans a couple of percentage points slower therefore lower in here noise marginally so there are some potential real benefits but ultimately it's about having a project to do and the conclusion is more or less the same with AP use but the difference between in our testing the rocking cool IHS for the our 320 200 G and the stock IHS for the our 322 energy is much smaller it's it's about two degrees as opposed to four to five with the Intel one there are a few reasons for that one of them is that the our 322 energy comparatively is a lot lower heat flux than something like an 8700 K you're dealing with less heat you're dealing with way less power and there's a lot less to dissipate so any differences are going to be smaller another reason that we don't see the big changes is because the design of the AMD ia jazz there's a lot of different form Intel's its first of all it's a pretty big IHS and secondly Intel again has these chamfered edges around it on the outside where rocky cool had some design liberties they could eliminate a couple of those and modify it so that there's a bit of extra surface area for dissipating the heat which helped out a bit obviously so at the end of the day same kind of thing with the AMD one as the in Taiwan just the thermal difference is objectively less in terms of measurable gains or improvements than the Intel option because again of the design differences and the power output differences ultimately we still think it's definitely worth deleting the APS if you feel like it if you're comfortable with it though the copper IHS isn't necessary deleting isn't either to be fair you don't need to do it but if you're using it in a living room HTPC and you demand silence for example deleting drops the thermals enough that you could then drop fan speeds significantly we're not talking four degrees here we're talking more than 10 that ultimately meets the original littered results if you were to lower your fan speeds with more thermal Headroom so you'd be able to have significantly quieter fans overall rocket cools D later works great for this and is something that we can recommend we've got a couple of them so we'll show that in b-roll as well but the rocket cool D later for the AP use we've used it a couple of times now and have had no problems at all in terms of safety quick recommendation on it if you're going to use their deal we'd recommend that when you put the CPU into the socket and start the delayed process with it which is turning a screw we recommend that you flip it over so if the IHS is down that would be the AMD included IHS at this point facing down that way when the lid the seal breaks on the lid comes off you have gravity working with you not against you so the lid should fall away from the SMDs there are a lot of surface mount devices on these ap use that means there is some more risk of damaging them but because rocket cools D litter is an actual tool meant for this you're way safer than the way we did it originally which was a vise and a razor blade so pretty safe overall and in the very least again you don't need to do it you definitely don't need the copper heatsink neither of these things are necessary to use the processor as it is but if you want some extra Headroom it's definitely worth it the heatsink less so than deleting deleting is not difficult with this though just throw some liquid metal on it when you're done reseal it and you're good to go and the IHS if you want to just have something more unique I guess throw it on there while you're at it it's 20 bucks no big loss if it's only a couple degrees better so that's it for this one subscribe for more as always go to patreon.com/scishow stoop ick up one of our mod mats currently on backorder or one of the Gion crystals
