welcome to another episode of the workshop and this is one that I've seen a lot of times the post usually starts a little something like this so it's summer and in this tiny room on my gaming computer and it is so frickin hot when I'm playing games I think it must be because my GPU is running at like 80 degrees my CPU is at like 6070 degrees they got all these fans are kicking out all this heat and I'm with you so far so my plan is I'm going to water cool the system to lower the temperatures and make it so that my room is a little cooler and more bearable well hold on a minute I may not be a fizzy Cola gist but I remember a little something from my grade 10 science class we did a unit on like that law of conservation of energy that would suggest that that approach may not work to cool down the room but of course we're going to investigate it today but before you watch the rest of the video vote in the straw poll below the video let me know do you think water cooling the CPU and GPU cooling them down will make the room the PC is operating in cooler or not intel has brought ddr4 to the mainstream with their core i7 6700 K and Core i5 6600 K processors check out the link in the video description to learn more okay so here's how we're going to conduct the test inside the sanity closet here I've got a sick gaming PC core i7 extreme edition 128 gigs of ram gtx 980ti you know the works this is a type K thermal probe running into the room with my thermometer that will be telling us the ambient temperature inside the room so right now we're just getting a baseline reading to give us some idea of what we're going to be working with but next we're going to go in and actually set up the machine to run inside this room okay so for our air-cooled scenario I'll be using an octave NH d9l heatsink and then I'll have a modest overclock just one of the the one-button biosilver clocks on the cpu and then for my video card I'll be using a high-end gtx 980ti in this case it's an amp edition from ZOTAC I'll be running Unigine heaven on loop and then I'll be coming back periodically probably about every half an hour to log the temperature the ambient temperature inside the room waiting for that rising temperature to flatten out when it's reached equilibrium with the climate-controlled office that surrounds this tiny little closet okay so we've run into a bit of a challenge in that I don't think we're going to be able to just wait for it to reach equilibrium because here we are three and a quarter hours on the nose later and we are all the way up to twenty eight point two degrees without any sign of that slowing down so what we're going to have to do is check on our results and then do a follow up tomorrow where we take the same space at the same starting temperature and then see where it is that we end up after three and a quarter hours let's call it 72 degrees will use that CPU temperature as long as we use the same one then we're in pretty good shape here and our GPU diode is at a frosty 64 degrees so that's with heav'n having been running all this time the room is noticeably warmer but of course we expected that so all that's left to do now is swap out these components so we're going to go ahead and change that NH d9l out for an H 100 I that's a dual 120 millimeter liquid cooler so we should be able to get those cpu temps down significantly and we're changing out our ZOTAC air-cooled card for one of these slick-ass bad boys this is that MSI Corsair collaborative hydro gtx 980ti so with that out of the way we can wait for the room to reach our starting temperature again and then restart the benchmarks there we go friends we are officially ready to rock so I'm going to go in there and start it we're going to run the test for 3 and 1/4 hours and see where it is that we end up and I already have a pretty good idea of where we're going to end up but hey I could be wrong so it's important to recreate the same scenario again as before so we're going to run those same benchmarks the system stability test we're going to leave the light on in the room I'm going to take my laptop out of here and let's see how she does startsnow Wow I actually couldn't have written this story better myself 27-point not 28.0 so after three hours and 15 minutes on the nose the room heated up the same amount in spite of the fact that our GPU temperatures are a frosty 53 degrees so let's pull that baby up right there 53 degrees on the GPU with the CPU sitting down at 40 50 degrees so both of them are cooler running but the amount of heat that they generate that needs to be dissipated into the room is identical because the thermal energy that's being output is not actually necessarily related to the temperature at which something is running so there you have it guys if the objective is to cool down the room then the only sane way to achieve that would be to water cool all the computers in the room and put a radiator on the roof of your building simple powerful beautiful that's a really old slogan Squarespace they offer 24/7 support via live chat and email and offer their service starting at only 8 bucks a month so anyone can build themselves a beautiful website using Squarespace all of their gorgeous templates feature responsive design so your website will scale to look great on any device I mean
