try to imagine yourself playing a very GPU intensive game something like Witcher 3 with the very powerful graphics cards can like a gtx 1080i but under one condition you cannot have any fan running whatsoever active cooling is a trend that's been around since the late 90s in fact much of the early kits were sold as aftermarket units the original PCBs did not come with fans because they weren't technically needed even though they did get very hot but nowadays of course almost any card you can buy that you can actually game on will come with the fan but let's try not using one well hold on a second let's not use a GTX 10 atti a card like that will certainly thermal throttle after just a few seconds of the GPU being under full load rather let's test something that's much less powerful and that will output significantly less heat something like an AMD rx 470 I chose this XFX variant of the rx 470 which you can find in Best Buy and online at amazon.com linked in the video description for one very specific reason that's because you can actually remove the fans just like that and from a practical standpoint the only reason you would want something like this is to swap out the fan LED colors something from white to red maybe or from white to blue you could just manually shut off the fans if you wanted to run this test by yourself but I do think it's cool to not have fans installed period it just looks just looks weird you don't see graphics cards like this anymore so I took this card void of any fans whatsoever I can't get over how weird this looks just strange and installed it into my AMD 1700 X Rison PC bill that's in the fan text p400s tempered glass edition - built it right here but I took the custom loop out of it right now it's being cooled by captain 240 e X and this card of course is just being passively cooled by the copper and aluminum combo we've got here three copper pipes and just an aluminum heatsink it's really all we've got going on here let's see what temperatures look like now right off the bat after installing the latest crimson driver for the RX 470 I realized that my temperatures were slowly climbing and they didn't stop climbing until around 65 66 degrees Celsius which is not a great idle temperature at all and this mind you is at a stock frequency just with auto-tuned voltages I didn't bother tweaking anything up front I wanted to have kind of a control test before we decided to tweak anything I expected we'd have to drop the frequency and probably under volt the GPU quite a bit so I ran the superposition benchmark from Unigine this is a super overkill benchmark I'll have more detail on that in a separate video but it just stresses the hell of the RX 470 and yet the computer shut off in like 20 seconds or so it actually throttled the GPU frequency down to a mere 300 megahertz on its own in an effort to keep temperatures below 90 degrees Celsius but that didn't really help after about 10 additional seconds upon throttling the entire computer decided to shut off oh and by the way our fps was terrible we're talking low low teens before the throttling and once the throttling occurred down to 300 megahertz our frame rate dropped to a mere 3 FPS so obviously a few changes needed to be made first up I had to reinstall these fans and get that GP to cool back down to around 35 40 C just put the fan curve on like 70 80 percent and in about 20 seconds or so the entire card cooled back down to what you would expect it to idle at around 35 40 C and then I just turned the fans off so they weren't running after that point even though they were still in stall that's why you see the fan LEDs you'll see them in the next few clips of b-roll so I decided to hop into the Whatman section of the crimson driver and reduce my frequency down by 30% which is the lowest that I could go and I also dropped my GPU voltage to 800 millivolts also the lowest I could go I wish that I could have dropped lower than that but the crimson software would not let me and I really didn't think that that was low enough 800 millivolts is only a 20% drop from what the car usually demands under full load most cards will require about a volt or so when they're under load so we hundred millivolts isn't a big drop and that showed in the next set of tests that I ran with superposition so even with the 30% drop in our original frequency again starting from about 40 degrees Celsius as well as a 20% drop in over card voltage just to the GPU the memory I didn't bother tweaking with that wasn't a big in effect as the GP voltage was I still ended up crashing the computer it just took longer for that to happen temperatures stayed in the 70s and 80s for significantly longer we actually almost finished the benchmark which would have been enough for me that would have been mission accomplished but that was not the case in fact it began throttling again at ninety degrees Celsius and once it did that about maybe thirty or forty seconds after the PC turned off and that was for I called it quits I couldn't do it with an rx 470 I probably could get by with a low something just super underpowered for talking maybe like a GT 740 that that might be a card that we could do it with but for now a mainstream card that you can game in 1080p 1440p with and be comfortable it's going to require some sort of fan or active cooling system you just can't get by without a fan unless you're willing to compromise severely on performance at that point you might will just buy something that is much cheaper that won't bring the frame rate that you're originally looking for so with that I hope you enjoyed the experiment I was just very curious I wondered if I could I could do something like that and have a you know virtually silent graphics card apart from coil whine which this one isn't really bad with if you liked the video be sure to give it a thumbs up thumbs down for the opposite click subscribe if you haven't already and stay tuned for more videos like this just interesting stuff here on the channel this is all is our studio thanks for learning with us and watching pcs crash you
