all right listen up everyone because class is in session I've got an important video for you today this is you might recognize is the FLIR one I picked this up at CES and this allows me to do something that my eyes cannot and this is see keep seeing he is a huge deal because believe it or not when it comes to the temperatures inside of your system some things are happening that you may not realize which is why today's video is extremely important we are going to check a couple of different things today we're going to look at an air-cooled system like the one you see behind me and we're going to be taking a look at a water-cooled system to see what some of the differences are and the way heat behaves both an air-cooled and water-cooled environments this should be good this is my 7700 K system that I built take a look at it with the naked eye right here you can see other than some LEDs on the motherboard you can't really tell that it's turned on but the moment we put infrared in front of it you can see there's actually quite a bit of heat already on the motherboard just from simply being powered on let me look at that that in itself should be pretty eye-opening on what's going on with your system when it's plugged in and not even doing anything but what about when you turn it on and there's no load on this system let's do a little time lapse to see what happens it's pretty interesting how the VRMs are already pretty warm even though the system is sitting here idle it's not under any sort of load and you can see the chipset there is looking pretty warm as well on a teeth spreader something else putting off a little bit of heat here that you can see is the actual built-in sound card so that's kind of interesting you know I just loaded up an overclock profile here at 5 gigahertz on the 7700 K and as you can see immediately the upper vrm heatsink started to get kind of well you can see the temperatures of change in there went from kind of a yellow to an orange immediately during booting what I'm going to do next here is I'm going to do an 8 o 64 stress test on the CPU and the memory so keep an eye on the memory going up and down right here I don't know how much that's going to actually increase on temperatures but the bright red area right there is V RM and the top right there is also V RM and this is chipset so keep an eye on this area these are the tubes right here for the H 100 that's keeping the system cool and let's see what happens over time when we put this thing under a little bit of load you can see the tubes have warmed up a little bit the VRMs are pretty damn smokin and the chips that didn't change to too much but yeah you can see right there though that we've got some pretty intense loads that take place on the cpu especially when they're overclocked and like right now overclocked to 5 gigahertz at one point 4 volts yeah in fact this h100 can't even really keep this cooled like it needs to so I'm going to go and stop the test before it before I blow it up ok so next up is graphics cards side note my skin is actually cooler than the temperature of the chipset there you go so that's what my hand looks so yellow and not red anyway we're going to go and do graphics card testing here one of the things I want to check for here on this test is I want to see what's actually happening with the heat pipes the heat pipe design is what so many of these companies actually tout as being you know what makes them so good so I figure let's check let's test that let's just let it time lapse once again see what happens over time with an MSI 1080 gaming X all factory fan control but it is overclocked to 2050 and the voltage is at 100% so let's see what happens and interestingly enough the pipes are pretty dang hot when I touch them but they are still cooler than the PCB is which is why they look cool on camera but the PCB is the hottest point remember this is showing us a range of temperature not a color as a representation of temperature so red does not necessarily mean red hot it just means that's the hottest thing on the image this could be negative 20 degrees Celsius and still be red if we were comparing it to something that was negative 50 degrees Celsius if that makes sense now back plates are one of those things that's always been a question is actually doing any good or is it causing harm some people believe back plates cause an insulation issue where heat can get trapped between the back of the graphics card PCB and the back plate causing more damage than good now we'll need more testing in the future to determine if that's true and there's a lot of variables and a lot of different backplate designs so there's no way to really give you a definitive answer on that one what I want you to take a look at here is a couple of things once you see the way the heat kind of spreads across the back plate as a graphics card gets hotter and I also want you to pay attention what's going on on the motherboard and around the graphics card I want you to see how the graphics card is actually affecting the temperatures of things next to it that's the whole point of this also to is I do have the span currently locked so that it's not going to allow the range of temperature to change as your graphics cards getting hotter so that's what I have it pointing at right now I want you to see the graphics card temperatures change in relation to the environment you know around it as a whole and you're going to see it probably jumped twice maybe once or twice on the temperature range where once the graphics card turns white it resets internet starts to turn white again so that's why you're going to see that all right enough talking let's go ahead and get the test going look at that look how hot that is the actual backplate is about as hot as the VRMs up there so that's why further testing on back plate designs is going to be a big deal for a lot of manufacturers to make sure they're doing it right and you see it just reset range again because it couldn't go any warmer than white so you can see we are now at 55 C on the back plate where it's touching right there and it's actually now hotter than the vrm you see how there's more white here in the graphics card than there is on the V RMS right up there yet the graphics card is now warmer than the surface temperatures of the vrm pretty amazing but check this out do you see how much heat is actually affecting the motherboard do you see how those three dots right there above the graphics card are just as warm as well some of the parts of the PCB here on the graphics card well that's where your m2 would be that's why case flow and air flow is hugely important when it comes to your case we'll talk a little bit about that in a second but yeah your graphics card especially air cooled cards blowing down on the motherboard are creating an issue where it is warming up parts around it well I wouldn't really call it an issue but something definitely keep in mind and why m2 placement is huge when it comes to motherboards it's also why putting them on the back of the motherboard tray sandwich between a back panel with zero airflow it's not necessarily a good idea so what about water cooling builds obviously that's going to be better well guys what we're looking at here is my water-cooled ITX build I did for fractal this is the define nano s it is a single loop incorporating both a gtx970 from gigabyte this is the g1 gaming and of course a 4790k i7 and an ITX EVGA stinger motherboard so the hotter part on the screen here that you can see is the chipset that is not water-cooled the you can kind of see the outline of the block right there that is where the water block is for the CPU and of course the graphics card is facing towards us so what we're really looking for here is I want to see what happens to the loop temperature as the temperature inside the system starts to go up so we're going to that's what we're going to kind of look for you I'm going to start a heaven benchmark and we're going to see what happens as we let it go I'm curious is what the loop temp is going to look like this loop is with glass tubing which is also an insulator glass as an insulator so we want to see here what I'm curious about how that's going to work out so let's just shut up and do it well temperatures are pretty much equalized to want to point some things out here you can see the loop started to glow because obviously it's getting warmer you can see the chipsets pretty darn warm and the vrn started to warm up one thing I want to point out here real quick though is you can see the warmth of the fluid right here in the glass what looks like right here the fluid leaving the graphics card being super hot is actually not what you're seeing right there is a bleed effect of the heat of the motherboard behind the tube actually glowing through the tube which is why up here it's not nearly as you can see right it's not that it makes this Bend right here it doesn't cool off as it goes through the bend it's just less heat glowing through but look at how hot the motherboard is the mother look how hot that motherboard actually got even on a water-cooled system right here part of the reason for that right now is I have the side panel off the case so there's very little directional airflow you see the RAM actually started to get pretty warm too so that's an eye-opener let's talk about this guys this is important okay class what do we learn today well although it's important to keep things like your CPU and your GPU as cool as possible with things like CPU blocks GPU blocks big-ass Noctua air coolers and such keep in mind that there is an entire system that is going on inside of your case that's the reason why we put our stuff in cases it gives us an enclosure to control the environment for cooling the problem is some folks believe that because they have a CPU block and a GPU block that they can run an external remote radiator somewhere else through tubing and not have to run any fans in their system giving them a nearly 100% silent system the problem with that is as you've seen with your very own eyes today there are still parts in your system putting off heat that have to be cooled your RAM your VRMs your heat sinks that are on your motherboard doing different things like your chipsets all of those things have to be cooled now I had already seen this sort of stuff before I may have got a laser temp probe right here I've used laser temp probes all the time but I've never had a chance to see how the heat of certain components affect things around it this is my first time spending any time with thermal imaging and it really was an eye-opener and it's going to change the way I build my systems moving forward so hope this has also shed some light for you guys on what to think about when you're putting too your systems what types of fans you use and where you place them there's actually some system integrators actually do this with all of their system design puget system being one of them they actually use thermal imaging to design their systems and that is huge that's why you're going to be seeing this now used in any graphics card CPU testing cooler testing in the future anyway guys that's all for today I am actually kind of sweating right now because I've been doing all this thermal testing in here and it's hot and I'm fat and so anyway yeah I'm going to go now before I start dripping sweat all over the place let me know what you guys thought about today's video if you have any ideas you think I should use this thermal imaging gun or the thermal imaging camera on let me know keep it clean let's keep it PC related only ish whatever experiments are bound to happen time to go guys thanks for watching as always I'll see you minute
