How to Fix Fan Noise and Heat – Complete Guide!!!

by birtanpublished on October 4, 2020

Tech family today we are going to tackle one of the most annoying things about modern laptops fan noise and heat in this video i'm going to walk you through every possible thing that i know of that you can do to reduce it or stop it i'm josh and i buy and review a lot of laptops and talk tech from the perspective of what it's like to own and use these devices and that's why i believe a video like this is so important if at the end of this video you like what you watched take a moment to smash that subscribe button hit the thumbs up

And the notification bell it shows your appreciation for the insane amount of work that goes into making these originally i was going to first provide a primer of why heat and fan noise is an issue in modern laptops and then talk about what you can do about it but the video was just way too long so instead i'm just going to cut to the chase and tell you what you can do about it at the end of the day all laptops perform differently so most of these solutions you really

Need to try on your own device to find which works for you i have with me the dell xps 9 300 one of the warmest feeling devices i've used in 2020 as i walk through this guide i'm going to perform these tasks on this laptop and at the end show you the results please note i will also provide some insights into what mac users can do as well now before we get into the guide heads up there are a variety of people who watch this channel with a range of experience in computers

From novices right through to those who code in vi i'm going to start with some really basic things that you can do and build up to the more advanced changing the laptop's cooling profile the first thing you should do is look whether your laptop has a quiet or cool mode this may sound obvious but to be honest it wasn't for me for dell you'll find it in dell's power management software for example gigabytes aero has one so does msi etc etc

If you can't find one on your laptop then just call the manufacturer to ask if yours has one and if so where it is in my experience quiet modes tend to prevent the fans from spinning above a certain speed and instead throttle the process of reducing its performance if it gets too hot you may also see a cool mode these tend to raise the fan speeds to make the laptop cooler to the touch unfortunately this means the laptop will generate more noise that being said these profiles are definitely worth a try especially if

You're doing lightweight tasks that do not need the full power of your laptop here are the results of the dell xps using its quiet mode and cool mode compared to the default optimize mode quiet mode is a tad quieter but really doesn't seem to do much in the latest version of the bios you can see some pretty decent differences when it comes to the cool mode though rather than spin the fans up that much more dell seems to have opted to more heavily throttle the power to the cpu to keep it cool

Unfortunately no laptop that i've tested with a quiet mode has ever had the fans turn off completely now if you have a mac you'll probably have the opposite problem rather than hearing fan noise apple tends to prioritize a low to no fan noise above everything their chassis will get very warm to the touch before you hear noise from the fans spinning up plus their metal chassis conducts heat so they can feel very warm indeed if you have a macbook you may want to do the opposite and increase the fan speed

Over apple's default that way the laptop doesn't get uncomfortably warm to the touch to do that you can download the app max fan control and then for each of the fan set either a constant fan speed or set the fans to start spinning up once the cpu temperature hits a certain range i tend to just set my macbook pro 16's fans to spin at a constant 3500 rpm each i find this is a good balance between keeping the chassis cool and a little fan noise next thing i'd like you to do is look

For software that is causing the fans to spin up oftentimes poorly written software can place extra load on your computer pushing your computer's processor to run when it shouldn't causing the fan to spin up to cool it to check this on windows press the windows key and x and then select task manager on the process tab order the processors by cpu percent in reverse order see if any processors are using a large amount of your cpu that shouldn't be for example i use an application called

Yellow mouse which makes the mouse cursor larger so i can better see it in games when i play on a high resolution display sometimes that software seems to go berserk and show up a massive amount of my cpu's power and fan noise is generated i found that if i killed the process by clicking end task the fans would go back to normal and i could reopen the app and it would work as expected on the mac by the way you go to spotlight and type in activity monitor and you can do the same thing as you can

On windows reverse sort by processor usage and kill the offending software please note one obviously some software is expected to use a large amount of resources like exporting a video in premiere pro don't kill these processors in fact only kill processors that you know what they are and are certain they shouldn't be using so much of your cpu two the chrome browser uses a notoriously large amount of resources if it's frequently causing this then try closing some browser tabs or restarting the browser entirely

If this still occurs try a different browser like safari on the mac or edge on windows which may perform better updating your software on the note of erroneous software another simple one make sure all your bias drivers windows version and software is up to date it is definitely possible that erroneous software may be fixed in updated versions or there may be improvements to how efficiently any software runs most computers have at least three places to do this your operating system for windows under settings

Your manufacturer's software updater here is dells the component manufacturer like intel amd or nvidia which may have drivers available for your computer before your laptop's manufacturer adds these latest drivers to their software updater oh and there's also a fourth your application that you're using might also have an updated version i'll post links to the common ones in the description below disabling turbo boost taking a look at how some of the quiet and cool modes work where they often

Restrict the power to the cpu one of the more extreme methods that can work very well for some users is to disable turbo boost turbo boost is what enables a cpu to race at speed above the base level on the common 10th gen i7 1065 g7 cpu it runs at a base speed of 1.3 gigahertz and can turbo boost up to 3.9 the higher the gigahertz the laptop runs the more heat is generated and the more airflow is needed to cool the laptop so fans spin up turning off turbo boost will have the laptop speed max out at its base clock this solution

Can make a huge difference to fan noise and heat i'd advise trying it out in the following circumstances if you know you are only going to do very light tasks on the laptop or if your laptop has a high base speed to begin with for example the older 7th gen i7 7500u processor has a decently high base bit of 2.7 gigahertz most laptop manufacturers offer the ability to change the setting in the laptop's bios often accessed by pressing f2 on startup be super careful of changing settings in

Here as it can really stuff up your system i prefer to change this setting in software using throttle stop you can select this checkbox here that way i don't have to restart the laptop to turn it on and off now i totally understand the people who feel that they shouldn't have to resort to turning off turbo boost it technically heavily throttles your cpu far below what is advertised by the manufacturer that being said it does work for making your laptop cooler and quieter in most

Instances here are my results from the dell xps 9 300. as you can see it does make the laptop run a little bit cooler and quieter at the expense of some cpu performance laptop risers and cooling pads if your laptop is still too warm what you could do is purchase a laptop riser or a cooling pad these lift the laptops up so there is better airflow to cool it cooling pads usually have fans that provide additional airflow on top of your laptop's fans

These are normally powered by a usb although these can work very well especially cooling pads both tend to result in a little more noise so only look at these if that isn't a concern for you the laptop rises because the fans from the laptop are louder when lifted off the table and the cooling pad because of their additional fans as you can see in the case of the dell xps 9300 the laptop performs substantially better with the cooling pad i purchased a rather cheap cooling pad from amazon that worked really well

And didn't add that much noise so i'll post a link to it in the description below next thing you can try is undervolting with undervolting you are trying to run your cpu by feeding it less power this can result in the cpu running a little faster as it doesn't produce as much heat and therefore won't throttle as easily to cool down to say it another way your laptop will run faster while producing the same amount of heat and fan noise but this video is about making your laptop run cooler and quieter

So why are we talking about under vaulting the reason is this if your laptop can process a task faster it can more quickly return to an idle state where it generates less heat and the fans don't spin as much sounds great right there is a catch if you underbolt your laptop too much it will crash for intel cpus on windows there are two easy ways to undervolt your laptop using the application throttle stop or intel's extreme tuning utility links in the description below i found that throttle stop works on more devices

For throttle stop you may have difficulty installing it if you get the missing dll error go to the link in the description below and install both the 32-bit x86 and 64-bit version once installed click the fivr button then unlock adjustable voltage and change your offset voltage apply the same to both cpu core and cpu cache to determine what a safe undervolt is for your laptop run cinebench r20 a couple of times to put a large load on your processor

If you get a blue screen of death or freeze your under vault is too great note if you start to get additional blue screens or instability in the days that follow when your laptop is under vaulted it is also probably too high as a general rule of thumb i start with a negative 100 millivolt and adjust from there some manufacturers like razer even undervolt their laptops out of the box by the way there are some very detailed guides on under vaulting on the net that go in a lot more depth than i'm able to do here

Definitely worth researching as you can see from my dell xps 9300 when the processor is maxed out the undervolt made my laptop run a little cooler and quieter but it also made my laptop run 200 megahertz faster on all cores for the same thermal profile the next set of solution involves taking the back off your laptop a lot of reviewers and youtubers make this seem easy and for some laptops it certainly is for many others it can be a challenging process tons of clips holding the

Laptops back in place or where screws are hidden under the rubber feet the risk increases here use a splotching tool be patient at all costs avoid damaging your laptop if it feels like you'll break something do not proceed i'll post the screwdriver with interchangeable tips and the splutching kit i use in the description below cleaning your laptop's fans advance your computer relies on airflow to cool it over time dust builds up amongst the fans and air vents this blocks the airflow and may result in more noise as

The fans spin up to push the required amount of air to cool the machine plus in many cases this can result in higher temperatures if not enough air can be circulated to resolve this you want to clean your laptop of dust after opening up the back of your laptop use a can of compressed air to blow the dust out of the vents and other areas your laptop's cooling solution generally works in the following way heat pipes dissipate heat from your cpu and or gpu

Then fans blow air over the heatsink at the end of the pipes to cool them a thermal paste is used to connect your laptop's processor to these heat pipes sometimes manufacturers use cheaper pastes or don't apply them correctly to solve this you'll want to buy a good thermal paste and reapply it i bought noctua's nth2 which i'll link below once you have the laptop open you should first ensure you are grounded so static charges don't occur and then unplug the battery you can buy grounding wrist straps to do this

In my case on the dell xps i could not pry the battery cable out so i decided to take a risk and proceed with it powered down but the battery still plugged in i would not advise this to replaced you'll want to unscrew the heat pipes and heatsink now often the screws over the heatsink are super tight you may strip the screws if you try to force them this has happened to me on several laptops if that starts happening to you stop instead purchase these small

Vamp pliers that i'll link in the description below this should enable you to get the screws out once you have removed the heatsink clean off the old paste with alcohol on a swab my noctua paste actually came with some swabs with alcohol on them already which was great once done and dried off apply a very small amount of new paste there are numerous videos online about the correct application of thermal paste i'd suggest watching some of these once done screw your laptop back together and you are good to go

Here are my results for the dell xps 9300 after a re-paste as you can see some modest improvement now after applying many of these solutions together you'll notice that in the cinebench test that i ran the dell xps got substantially faster but it didn't run any cooler or quieter that's because dell natively tries to run this laptop as fast as possible in the same thermal envelope this isn't all bad news though as i mentioned earlier in the video this means it can process tougher tasks

Faster and more quickly return to an idle state where it produces less heat and fan noise now your laptop may of course perform differently with these solutions that being said here is my final one some laptops just run loud and warm have high pitched fan noise and no matter what you do nothing is going to change that and i'm sorry to say you need to get a different laptop right now for light to moderate usage i feel the macbook pros handle heat and fan noise pretty well for a power user look towards the hp

Omen with ryzen that does a phenomenal job well that's all for today folks if you like this video you know what to do smash that subscribe button click the thumbs up and the notification bell and if you want to show some additional support become a patreon member until next time i will catch you later
