EZBook X4 Fix Thermals And Boost FPS 200% Gemini Lake TDP Tweak


EZBook X4 Fix Thermals And Boost FPS 200% Gemini Lake TDP Tweak Chris here with the EZBook x4.
So I'vejust finished my full review of this particular model and before I can do anysorts of mods it's always the case with my reviews I have to review them asstock so that goes for Android devices and must be the stock rom no custom romsand when it comes to things like tablets and these laptops no modifications tothe one so ever so my review with the stock 9 watt TDP that it has set thepower limit it gets up to 93 degrees Celsius which is a little too hot so I'mgoing to remove the heatsink here take a look at the thermal pad that'sunderneath perhaps re paste it so I've got somesimilar paste right here and then add a thermal pad onto the top to see if I canlower those temperatures now if the temperatures do turn out to be lowenough then I will also try running it with an unlocked or increased powerlimit always place to be safe so I've unplugged it here now this will probablyreset the BIOS settings so just be aware of that here but why I'm unplugging itso we don't have any power going through this there should be no power goingthrough it but imagine it accidentally turns on we could short something outalso try to earth yourself and use an anti-static mat okay so I've got theheatsink off as you can see and it just had this thermal pad on the top of itand I believe what's happening in my case here that there seems to be a bitof an arc to this copper heatsink and so it's not actually sitting 100% flushapplying pressure or enough pressure to actually have a good contact with thetop of the CPU die there so that is probably why I got up to 93 degrees soif you placed a thermal pad on top that will give some more pressure between therear of the case the alloy which is right here so you have that pressingdown a top on top of it then and I don't think it would then run into any problemso that's prolly all you need to do interesting to note here as well the RAMso we've got four gigabytes right here and space for another four so eventhough windows reports that send dual-channel it may looks like and wellnow doesn't it that it's only running in single channel probably the way thatthis is set up you can see here that the stocks will pad it's very thin it's onlyhalf a millimeter the thickness of there so that also could be a bit of a problemwhy it didn't have so much pressure so in the past with the bay trycheery trails and the Apollo Lakes what I used to do was just put a copper shimon top here now there's a little bit risky now you use a thermal paste that'snon conductive so this one here from Noctua isn't so if use one of thoseliquid metal ones you will definitely run into problems you need to protectall those little surrounding resistors now the issue with this is that there'sa very small gap between the resistors and then the copper shim so in theory itcould move it could touch it could shut something out now I've run this and donethis now for years without any issues so I don't think it's going to be a problembut I think here that it's not actually needed so I'm just gonna put a littlebit of thermal paste on the top here and then simply place the stock copperheatsink back on there because it's a large copper heatsink and this shouldreally do the job especially when I add a thermal pad onto the top of it now tomake sure it's gonna apply pressure without the issue that I had when Ifirst took my soph I could see that it wasn't and actually had a little bit ofa bend to it upward so it wasn't applying enough pressure so what I'vedone I've just bent it inwards ever so slightly you don't wanna do it too muchthen it won't actually sit flat on top of the CPU so I've done that just alittle bit and that should help I think alright so I'm gonna try and put thetiniest little bit here no I'm not left-handed it's the camera tripodthat's in the way so just a very small little bit now you use your own methodfor this replying thermal paste this is just what I like to do I like to use aplastic bag then to get a very thin even coat I know maybe it's not the bestmethod but for me it just works so do whatever works for youokay so done it doesn't actually spread out as good as I hoped it would it's alittle bit thicker the NT h1 paste here that I have used then the typical ones Inormally go with and now the placement of the thermal pad so I'm gonna go witha two millimeter thick one here which could actually be too thick might haveto be one millimeter but even so I'm gonna put it about here where the thechipset was where that dyers and then I'll apply now pressurestraight over that transfer heat onto the back of the case so I get the caseon I think it's still gonna fit just fine but before you do that don't forgetof course to plug that battery back in alright so it closed down perfectly finewith just a little bit of pressure on here I hope that 2 millimeters isactually thick enough if not I might have to go a little bit thicker but thisshould be fine screw it in place here it's not bulging nothing strange let'sboot it up now and check the temperatures alright so the results arepretty much fantastic okay you're looking at 74 76 degrees at the momentand that's a huge improvement over my 93 degrees playing games but look at theframe rate here that is because I have removed the power limit so the powerlimit now is completely unlocked it can consume all the power at once andperformance is up now because this is project cars which I tested in my reviewran at 5 frames per second and it's getting up to 20 frames per second nowso that is a performance increase of about what is that250 300 % that is really something so that is good to see we can finally openup the performance of the Gemini lake in 4,100 here alright so it looks like thepower limit being completely unlocked is just a little bit too demanding here canyou can see that now got up to 86 degrees so yes it's getting hot the caseis getting hot but I just wanted to test what kind of temperatures that wouldreach without any power limits now I haven't shown you but without the powerlimits being touched so the Stockwood comes out of the box which is 9 wattsyou only get temperatures now with my thermal mod up to about 71 degreesmaximum so it's lowered at about 20 degrees which is really good now toscroll down here and show you now that because we've unlocked the power limitsthat it can consume now right up here to almost 15 watts so that's quite a lotfor this chipset and remember that the stock will only be about 9 watts maximumthat it will let the CPU consume so boost the GPU performance massively butit will lower battery life it will increase heat and the case does getreally quite hot now I have to show you counter strike again so this is the samesettings as my review with 720p and on the low settings so the frame rate haspretty much just doubled here because of my review it was around 20 frames persecond it's now up to about 54 you can see maximum so it's made a hugedifference and to see here that not like project carsthe frame rates are not the frame rate the temperature is sticking to about 80degrees maximum it doesn't seem to go over that which is really good here soit seems it's going to maintain it with my thermal pad mod and no power limitsset half-life the Lost Coast is running so much faster as well the frame ratehas doubled over the stock nine watts power limit that you get out of the boxand the OpenCL score now gets a healthy boost of almost two thousand pointsthanks to the unlocked power limits so now checking just how hot it's gettingafter 20 minutes of gaming the case of it at the top here 42 degrees so that isvery warm to the touch getting quite hot remember that thermalpad is transferring all that heat over now to the case so there we gosurprising what a little bit of thermal paste and a thermal pad can do to reallyimprove temperatures so if I didn't change the power limit max temperaturesare about 70 degrees that has dropped down a huge 23 degrees over the stocksetup that they had on this I've had the thermal pad but as I noticed it wasn'tvery good contact and pressure being applied from the copper heatsink ontothe chipset itself so that was why my unit got really hot this might not behappening to yours so if you do want to really get that massive amount ofperformance there's a link in the description of this video they will headover to my website to the forum of where you can remove the power limits withsoftware because when you change it in a bias it doesn't actually seem to takebut with software it will and there you can just completely unlock the GPUbasically is what is happening so it'll clock up as high as it once uses muchpower and you double your framerate in gaming which is really amazing but itwill get hot thank you so much for watching this review and best of luckwith your own thermal mods there with the EZBook x4 .
