gigabyte made this it's a heat sink you've probably never seen one before and this one has aluminum fins so they're breaking the trend of motherboard manufacturers we're very happy that gigabyte has decided to do that on the board it's on currently the gigabyte gaming 7x 470 board it's not actually necessary which will show you through thermal testing today we're gonna put in some probes on a couple of MOSFETs running it through various tests of the 2700 X and looking at the thermal results and then talking about why they are the way they are before that this video is brought to you by thermal takes view 37 case the vo 37 focuses on highlighting custom PC builds with its full panoramic window and tinted front acrylic and our thermal testing the view 37 performed reasonably well when considering its looks focused build which is partly thanks to the airflow design and the removal of a bottom power supply shroud for a balance of looks and performance check the link in the description below for the view 37 so as noted you'll see in a moment that this isn't entirely necessary on this motherboard but it's a good move in the right direction and if we can get manufacturers into the habit of making heat sinks with actual fins instead of just a giant block of aluminum with no surface area that would be a good thing overall because eventually these types of designs as simple as it seems do carry over to boards like the Intel boards for example where you're probably dealing with higher power consumption power throughput with a heavy overclock or two might carry over to boards even an export 70 line that just use weaker power stages and fewer of them for this board the gaming 7 we have a build Zoid analysis of it already which you should check out on the channel if you haven't but the short of the important features here is that gigabyte using a 10 plus 2 phase setup and they are using IR 3553 MOSFETs which are 40 amp power stages so not really that in need of cooling in the form of a heatsink with fins but it doesn't hurt the asus motherboard we have the crosshair 7 Hiro is kind of like the gigabyte vrm except even more extreme it uses 60 amp power stages on also a 10+2 design so it's even less in need of heat sinking but let's go over the numbers for what our K types said when we put them the the MOSFETs we had to on here primarily so we had one on the what would be the top side of the vrm and it was on the inner MOSFET so it's gonna be the warmer one which is adjacent to the SOC vrm and we had the SOC beer I'm running at 1.2 volts for the overclocked tests which would generate some neighboring heat and kind of warm that up we also had a probe on one of the central MOSFETs over here on the vertical part of the vrm the core vrm and it was in the center because that's where it'll get the hottest so we wanted to see what the hot spots looked like let's get the chart on the screen with the 2700 exit left to stock and XF are two configured to stock settings we measured a maximum v core vrm mosfet temperature of fifty two point four degrees celsius with a forty one degree measurement for the top mosfet measured TDI was fifty nine point five note that these are not deltas over ambient they're just straight temperatures ambient was twenty-eight degrees for every test and we did actively log it anyway just in case overclock into four point two gigahertz and one point 4 volts 1.41 pushed our MOSFET temperatures to sixty five degrees for the last V core MOSFET or 51 for the top MOSFET this is with extreme LLC four V core and high LLC for SOC voltage note that this is also with an SOC voltage at one point two so our neighboring SOC is providing some heat SOC vrm at these settings from pushing 139 Watson to the motherboard for blender at the EPS 12 volt rail in stock or about 186 watts when overclocked this is about a 30 minute test and we're measuring the average high temperatures after that steady state is reached removing the heatsink entirely the Left MOSFET operated at 56 degrees Celsius so about four degrees warmer than the complete stock configuration with the heatsink which was 52 degrees the top MOSFET operated at 56 degrees Celsius for a 15 degree increase over the 41 degree results with the heatsink there's clearly an actual advantage to having a heatsink and that's primarily realized at the top part of the vrm but it's ultimately not a make-or-break situation removing the heat sink and overclocking still keeps us within reason there is no real change for the left side and we're in variants of the original overclocked with heatsink results there's however a 16 degree increase for the top MOSFET even still that FET is still only hitting 65 point five degrees which is completely reasonable as we said in builds wideo part of the reason you're seeing the performance you are is because we think these vendors might be planning for a future higher core count CPU amphoras gonna be around for a while the board vendors might be trying to plan ahead so that their motherboards remain relevant and they don't have to keep refreshing them every time a CPU launches so that's probably part of why the VRMs are overkill on most of the x4 70 boards right now that we've looked at and also would explain of course why you have potentially more powerful heat sinks that are needed of course that's a good thing to do in general in terms of the temperatures you want these things to run at 4 capacitors you probably targeting under 105 degrees Celsius at 105 see a lot of caps on the market will last either 5 or 10,000 hours some bad ones are 2.5 thousand hours that's at 105 C and you start losing large portions of life for every 10 degrees Celsius you go up in capacitor temperature for the MOSFETs which are the parts that are actually getting warm that we're measuring you really don't want to go over 125 150 C depending on if you're talking about t KS or whatever its internal over temperature protection is if it has one that tends to be 150 degrees Celsius and at that point you might get some D rating you'll definitely get some inefficiency and if you really push it too hard it could pop but most of the MOSFETs on boards like this have over temperature protection that should prevent that scenario from happening clearly we're very far away from 150 degrees we're still far away from a hundred 25 degrees so either way they're number you pick you're well within safety margins even without a heatsink of course we'd recommend leaving it on because doesn't hurt it helps performance clearly if you put a Fender ectly over it it'll help even more we had no airflow for this test by design because we wanted to just do it without air flow and see how much difference we saw and I mean it's it's fine it helps to have it we're very happy to see gigabyte adding this but it's also not necessarily on this board and it's not gonna be necessary on the other board of this type with an actually really good vrm for rising to overclocking just because you're not gonna be pushing that much power in general unless you start doing things with L on to in which case you have different things to consider anyway as for the power going through these builds I'd has a video on our channel already talking about that he gives all the current ratings theoretical voltages watt draw stuff like that check the video for more information on that there is a bit of an exponential voltage curve as frequency increases so once you start hitting 4.2 gigahertz to get beyond that or even to four point two requires we've actually plotted it out for a future video but the curve basically goes like that so it's more of a straight line at some point so you do kind of run into voltage law walls before you run into cooling walls with a VR mm anyway and rise into is certainly power-hungry but it's got limits still so yeah well done on the vrm cooling and the vrm in general gigabyte the whole thing is good in our books the heatsink is completely unnecessary but we're not gonna be mad about it because this is what I've been asking for for a year now I'm happy to see it and I'm excited to see it for boards that actually do need it which will be coming out at some point this year as for the rest BIOS is somewhat barren on the gigabyte gaming 7 we would like to see more memory some timing options we'd like to see better tuning for memory sub timings with various kits there are some kits that work better than others in this board the gigabyte board needs some work in automatic memory timings in general for anything below that kind of primary six or so timings and also more power limit options would be nice to see so BIOS is definitely gigabytes weakest aspect of their motherboards but the vrm is is doing quite well so overall we could recommend the board if you needed something in this price range there's not a lot to be mad about if you really need something heavy-duty for overclocking a su still has the Best Buy us right now for Rison mm just kind of a question of whether you're really going to need all of those options and a lot of people don't and you do pay for those options so if it's not something that you know you're going to use then you could save some money so then the next board that we'll be looking at is the crosshair 7 hero we use this for some of our review as well we're using it and a lot of other testing for feature tests with Verizon to check back for that subscribe for more always there's a lot more coming out soon go to patreon.com slash cameras nexus tell us that directly stored on cameras nexus dotnet to pick up a mod matte like this one which is on backorder now we'll have more in and a couple of probably let's call it five to six weeks to be safe they'll be shipping out and i'll see you all next time
