that you just heard is coil wine it involves literal components on the board namely inductors which oversee current regulation at certain power delivery levels however inductors will vibrate creating high-pitched squeals graphics cards are notorious for varying degrees of coil whine because they experience frequent current changes depending on graphical demand and in the case of the K bulik dell XPS 13 which i reviewed right here coil whine is the plague it litters the entire motherboard specifically right here which is right where the CPU is located the wine has varying degrees of pitch and loudness and is persistent for roughly the first two minutes of start up until CPU usage levels off the only reason I haven't returned mine is because it's inaudible when I start shows on Netflix that would be the final straw for me but open up Google Chrome especially with hardware acceleration enabled microsoft word heck even a photo and you'll hear at least a few seconds of cringing metal hiss something else i've been able to deduce regarding the issue is that it's relatively isolated to the 13 Series the Dell XPS 15 cepting curd with have had no such wine and a comparable cable ache i7 ultrabooks like the Lenovo yoga 900 cha reviewed right here exact same specifications by the way don't have any coil whine whatsoever Dell has responded in a few rare instances to this issue via forums but of course nothing is likely to change for this generation of laptop the previous skylake model is also plagued with this issue by the way needless to say fixing coil whine in general let alone on a laptop this size is next to impossible isolating the exact inductor responsible would be troublesome and even then only a few materials can be coated over it to suppress the vibration not prevent it from happening but just to suppress it make the sound a little less prominent and I have a feeling the coil whine is coming from more than one place as I can typically hear more than one high-pitched tone coming from the laptop at any given time on screen graphics definitely instigate the sound which is why Cinebench r15 cpu test prompted only a fan spool no coil whine whereas the OpenGL test resulted in some of the worst coil whine I have ever heard I have a feeling that 1080p model of the XPS 13 also suffers here despite driving a fraction of the pixels so why did I create this short little video obviously to reveal the coil line issue think of it as PR the more you about a laptop the more comfortable you'll be about the purchase in general I spent fifteen hundred bucks on this thing I didn't even think to Google something like coil wine issue for the XPS 13 because I didn't expect it in a laptop of this caliber to be quite frank do I still recommend it though yeah I mean it's still a good laptop despite the noise sounds a bit like a hard disk drive so it'll be nothing new for those of you who are already sporting one but I am aware that this information will change many minds look I'm not biased about the sort of thing I even paid for this laptop out of my own pocket the coil whine is there it is frustrating it's annoying at times but that's just it at times it's intermittent not persistent and that's why I can deal with it it's not loud enough to where my classmates are always going well what is that what is that you know what's that loud noise so it's not like that even in a quiet lecture hall you'll still be okay with it unless you're doing something really crazy like rendering a video in the middle of class or something like that and they've actually been cases where people have purchased this exact laptop and not how to coil - use at all so you might get lucky but chances are you'll end up with one that does have coil whine and that's why I made this video just to let you know that it is there it's not too annoying most of the time every now and then you'll hear it squealing where the heck is that coming from it's coming from the laptop unfortunately and I hope that they'll kind of tries their best to eradicate that in the next generation of the XPS 13 other that's a beautiful laptop I got nothing else to complain about really except for the chin cam but that's something I knew about going into it if you liked this video be sure to give it a thumbs up and give it a thumbs down if you feel the complete opposite or if you hate everything about life be sure to click the subscribe and if you have any stay tuned for a review of the AMD rx 470 they picked up from Best Buy for a hundred and sixty dollars this is Salazar studio thanks for learning with this
