Laptops often do not offer any voltage control, but some kernels for smartphones will allow you to adjust the voltage going to the SOC. If you are willing to put many hours into stability testing, and have an unlocked bootloader, root access, and the right kernel, then you can have a go at undervolting the SOC, and testing for stability. if you have a good chip, you can extend your battery life by a small amount without giving up any performance. The same applies to laptops and desktop PCs, though there is little reason to try it on a desktop PC since battery life is not a concern, and the main reason it would be done there, is if you were going to passively cool it.
The reason for undervolting a laptop is to make it generate less heat by pushing down the core voltage (and probably other voltages as well) as much as possible without having to reduce the clockspeed to maintain stability. By generating less heat, you're less likely to experience thermal throttling, but less heat output especially means less fan noise. In order to do this you basically do the same thing as when overvolting to push an overclock further - but in the opposite direction. And by this I mean that you will need a laptop which BIOS supports editing voltages, which sadly isn't that common on laptops. But if you're lucky to have such laptop, push the voltage down in small increments (-5 mV), then stresstest it for 10-15 min (or more if you want to) using something like Aida64 or similar, then rinse and repeat until failure. Upon failure, back the voltage up until it's stable. Then fire a stress test for maybe 4 hours or so. If it doesn't fail, well congrats! However still keep in mind that it may still fail even after 2 weeks or so. After 2 weeks, I'd call it stable. You can also apply the same concept to the CPU Cache Voltage, and the DRAM voltage, all to reduce heat. But in that case, wait until one part is 1-2 weeks stable before moving on to the next part.
i will always remember when while playing modern warfare 2 i looked at my tower and my cpu cooler was still. There was some panic then i realized it was so cold in my room that the cooler just stopped.
Of course the reason those little transistors in your CPU switching on and off takes energy is because the transistors in question are MOSFETs, the same as the big ones on your board, only smaller, and there are literally billions of them. Apart from a small amount of leakage, in modern CMOS technology when they are not changing state they don't actually use power. The gate though, the part that turns it on and off, is inherently somewhat capacitor-like, which means it needs to be charged to switch on, and discharged to switch off. The energy needed to charge that is then wasted as heat, billions of times per second. It's amazing, actually, that these things heat up as little as they do, if you think about it.
The reason why higher clocks raise the Heat is because every clock makes a short circuit. This is because the Fet's(transistors) have a little capacitor at the gate and need some time to change from open to closed. So there is a time where the fet for 1 and for 0 is closed so it shorts to the ground.
You should have talked about why amplifiers get hot, but don't need coolers and don't get damaged because of the heat. In some cases, the heat it discharges is a good feature, such as for Class A amps.
My old MacBook Pro got stupidly hot during intense use. Shit turned into a stove top on the bottom. Fans also sounded like a plane taking off (this only happened when exporting a 1080p video or something.)
i would like to call processor as zero efficiency part, they radiate all wattage used as heat. but with an speaker amplifier those can be 90% efficient, converting only 10 of wattage used to heat.
Hey LINUS Ive got a Question -------- How much can you overclock a compter in the coldest place on earth ?, with the computer indoors and using outdoor sub-zero temperature for cooling either by air or liquid system...
an interesting avenue of heat generation is through destruction of information. Due to computers being n0n-reversible, (cant go backwards through an AND gate), information is destroyed, and entropy is increased.
Faster clock speeds = more energy used. Why? Because while the transistors in the chip are in the process of switching between 0 and 1 (the 'transient' state), the power that goes into them is lost as heat, as in this state, they're pretty much just a resistor. The faster the clock speeds, the more time spent in the transient state.
It's simple AF when you know physics When a lot of electricty (more intensity than voltage) electrons excite things around where he pass (more voltage is more excited electrons) And temperature is excited atoms
Then when we OC a cpu for example, it affect the frequency of how fast current pass (like 5 amps per seconds then oc it could be 9, you understand) and sometimes it affect the voltage (Like 5.2 GHz 7700k which set it on 1.57 V)
Why not make processors higher voltage & lower current to reduce heat, just like how electricity transmission is preferred at higher voltages. This should reduce the heat right?. Or is it that the current silicon based VLSI can manage higher voltages?.
My pc case is too small so half of my heatsinc sticks out of my case, so now I have a hole cut out at the side of the case to protect the rest of the components.
I'm answering before watching the video: Because of the Joule effect, when you have a current flowing through a conductor the free electrons move stochastically but with a bias in the current's direction, so when the electrons "collide" with a bounded atom some of their kinetic energy is lost and transformed into heat. After watching the video I'm not surprised that Clausius theorem is invoked, thou it is a somewhat valid explanation thermodynamics is a statistical phenomenon, so while it does tell you that electronics will get hot it won't really tell you why (plus if they are made of superconductors then they won't get hot at all).
electricity in general gives off heat when there is a really high level of intensity (measured in amps) in a small copper wire. the smaller the wire, the less Amps it can handle.There are reference charts for this. A single 12V+ rail on an Evga 500b bronze 80+ PSU can provide up to 40 A. if you think about a 95W cpu on 1.4V, then the cpu is pulling 67 A in total throughout all its internals.... yeah its gonna heat up.
you are right, the transistors create heat. but if you would like a more specific aspect of a transistor, it's the fact that transistors are not perfect a perfect on off switches. They will have a slight internal resistance that increases with heat. the faster they are switched the less time they have to cool down. The more they heat up the slower they are at changing states, which increases resistance, which then increases power dissipation which increases temperature, so basically a self destructive circle. this is why CPUs will throttle and slow down because the transistors can not simply keep their switching speed.
So like normal... Energy cannot be created nor destroyed. However energy can be converted from one form to another such as from kinetic energry to heat and sound energy for example
my PC is soooooooo frustrating!! keeps crashing when gaming. I think the motherboard is overheating, the place I got it from says its fine, friend of the family thinks the graphics card is broke and another source says Windows is the issue!! ;(
I got a question that's been bugging me for a while. In supercomputers which run simulations with complex physics and math involved, they stack cpus with many cores. Why not take the most efficient chip currently available and just make it bigger? Like a motherboard sized cpu,with a motherboard sized cooler etc.Yea it's gonna be huge, but i believe it would increase the physical space efficiency, i.e more cores in less square meters of server cabinets
The reason why they don't do that is that Chips are not manufactured one by one. Instead, they build a big ¨Waffle¨, then cut the individual chips from it. That way, if there's a defect in the waffle (which is almost guaranteed to happen, given the complexity of the process), they don't have to discard the whole thing and start over, but instead just discard the chips made with the defective área. That means that the bigger the chip, the more of the waffle ends up discarded when a chip turns out defective. Which makes the whole process more expensive. In your example, we just can't make a chip the size of a motherboard, because we can't manufacture a waffle that has such a continuous área completely free of defects. At least not at a reasonable Price. Oh, and by the way, the waffles are round while the chips are squared, which means that the larger the square chips, the more of the round waffle gets discarded even if no defects were found. Another reason is energy efficiency. Inside the chip, current flows through microscopical copper tracks between components, and because Copper is not 100% conductive, current is lost in the form of heat. The longer the track, the more power is lost. And the bigger the chip, the longer those tracks need to be. Also, thermal dissipation. You need heat to be transferred away form the chip uniformly across its Surface (i.e. avoid ¨hotspots¨ that can damage the chip)That's why chips have a metal cover with high heat conductivity so that heat distributes uniformly across the whole thing . But because just as with copper and electricity, no material is 100% perfectly conductive to heat, the larger the Surface, the more heat will just lump in certain áreas. And finally, cooling. Let's say you solved all the aformementioned issues and managed to cramp all of that system in a smaller space. That would be a problem, because you're still using more of less the same power, thus generating roughly the same heat, but now the volume of air around your system is much smaller, and there's only so much heat a given volume of air can absorb in a given amount of time. So to keep your system cool, you'd either need to increase the volume of air in the cooling system at any given time, thus forfeiting any space efficiency gained, or you would need to increase the airflow speed, so that the volume of air gets cycled faster. That means running vents at a faster speed, which would increase noise levels (and remember, noise is wasted energy too) and make those vents more prone to mechanical failure. And if you're thinking ¨Liquid cooling d'uh¨, remember, you'd still need the exact amount of airflow, because all you've done is replace a heat sink for a radiator. And because your heat source is now the size of a motherboard, that means larger amounts of cooling liquid being circulated at a given time, which means wider pipes, which causes turbulence (fluids don't move at the same speed across a section of pipe: they move faster at the center than near the walls. the wider the pipe, the higher the differences in speed), which means higher pressure to keep the flow going, which means bigger and more powerful pumps, all higher maintenance and more and more energy waste...you get the idea. Long story short...that's why making huge chips is not such a brilliant idea. Sorry.
English isn't my first language, and I observed that you spoke quite fast in some of your previous videos before, so I thank you for not doing it in this video :)
Heat is basically just "how violently are the particles vibrating?" Move a load of electrons(which is what electric current is) through a conductive(or even better, a not so conductive) material and those particles are gonna have fucking seizure.
No joke. between my 50in tv and my ps4 in my small bedroom, if i play for a few hours and leave on perhaps its on for 4 hours? it heats up the whole room pretty fuckin well by the heat thats being dissipated. I wonder if ill still be able to heat my bedroom when i move into my condo as its larger. But interesting how much heat is put out. I mean really, heating an entire room within a few hours.
older electronics used to not require Cooling until they went past 16 bit hardware. yeah that original NES or SNES does not use cooling, they didn't need it cause they did alot less compared to the N64 PS1 Dream cast and Original Xbox. yeah these are very old electronics, smart phone manufactorers not putting fans inside those phones or current TV manufactorers not putting fans into those tvs need to put those fans in. they aren't the NES or SNES
at the end of a techquickie/linustechtips video called"How to destroy a phone": Linus: "...and after you have hit it with a hammer, you could make a website to brag about it's death using Squarespace"!
Every single conductor outside superconducting temperature (liquid nitrogen temp at the warmest) opposes current flow. That's where the waste comes from.
I am going to get an Omen laptop from hp and i am asking this question:Can i run TF2 on ultra with these settings? CPU:Intel i7-7700HQ GPU:GTX 1060 FULL HD Am i able to? Or is it overkill?
All electronic conductors will make some heat. Every type of conductor has some resistance. Heat is a function of transfer of electrical power. Greater efficiency to get a task done releases less heat, because lower power factor is used. There are limits to how much efficiency is possible.
here's a silly thought. could you salvage the internals from a mini fridge or an air conditioner and re route the pipes onto a cpu or gpu heat sink? im thinking you could maybe set it up like a water cooling loop.
the compressor would burn out quickly. they aren't meant to be running for hours nonstop. But good news is you can buy a phase change cpu cooler that is basically an AC unit for your cpu that's meant to run that much.

Hey man ! Could you guys make a video/guide about undervolting laptops cpu ?
Rod Cord it's not always about the power. he might be doing light tasKS and needs more battery life
Rod Cord bs, you can undervolt quite a bit until you hit speed loss.
i've heard you can undervolt if your cpu throttles. that way you actually get BETTER performances by undervolting....
Laptops often do not offer any voltage control, but some kernels for smartphones will allow you to adjust the voltage going to the SOC.

resistors don't control current in modern day pc cpu/gpu - voltage regulator module (vrm) do, which are switching type dc buck converter.
Transistors are in fact a bit like variable resistors, which explains the heat generation fairly well actually.
