hi.. i have an MSI GF65 thinUE (the Canada variant i think, .. inside there are copper pipes from the crappy 3060 and the intel cpu... if i put 2 peltiers thermo electric coolers and pressed them against some of those cooper pipes... would that cool things down ???since this will be on the bottom of the laptop.. any condensation would drip onto the 2$ cooling pad... the laptop is raised at a, i dunno.. a 15 degree angle ? very certain that all condensation if any will drip onto the laptop cooling thingy....

small question, can i use usb power to power the peltier thing ???, it needs 55 watts to do its magic and i want 2.... so if my elementary math claas serves me well.. id need 110 watts

PS in this scenation i will keep the bottom plastic of the laptop removed
also im french Canadian so please forgive my grammar and lack of punctuation... actually the punctuation is simply because im dumb :)

and furthermore the laptop doesnt overheat, but after i lost a nvidia geforce gpu, ive been paranoid about temps.. so if speedfan has that little fire icon, im not comfy

No it won't since you'd be overwhelming the little coolers on your laptop.

since this will be on the bottom of the laptop.. any condensation would drip onto the 2$ cooling pad...
Physics and Chemistry will tell you that humidity will make it's way around your PCB and that will in turn hinder your laptop's overall longevity.

the laptop is raised at a, i dunno.. a 15 degree angle ?
If you've done trigonometry, what sort of height do you gain from raising the rear or the laptop by 15 Degrees?

and furthermore the laptop doesnt overheat, but after i lost a nvidia geforce gpu, ive been paranoid about temps.. so if speedfan has that little fire icon, im not comfy
You're overthinking things.
1| Replace the thermal paste and pads with higher quality compounds/putty(for the areas that have pads)
2| Make sure you don't overapply the paste
3| Make sure your vents are cleared of dirt/debris
4| Prop/raise the laptop up with an eraser or even a sharpie to lift the laptop's base off the table and allow for cooler ambient air entering the vents.
5| Undervolt the processor and GPU.

thank you... i mentioned the 15 degree tilt to show that the condensation if any will not streak towards any other mobo components, i am a star citizen fanatic, so i dont thin, i can "undervolt" anything , also i didnt overclock anything, the only thing is that i selected full pc performance in the Linux power settings, should mention that i reside in the Philippines a tropical country... ambient temperature is in the 30's (celcius)

If you search you will find large number of articles and video that explain why peltier technology is not used in cpu coolers.

The short version is if your cooler uses 55 watts of power where does that energy go. It is all converted to heat that you now somehow must get rid of. There is some cooling effect but many sites say these devices are only about 10% efficient. That means you are now getting about 5 watts of cooling and but now need to get rid of a extra 50watts of heat.

Yes, you can absolutely do this. You could also buy a small freezer and keep your computer in there and run some wires out to a display and keyboard. Or immerse it in a chilled dielectric fluid. But I strongly recommend that you do not do any of those.

Peltier seem incredible for computer cooling, compact and cold. Problem is what's happening with them is they make it cold on one side by pumping all the heat to the other. Adding 110w of Peltiers is going to dump as much heat in your system as cramming a desktop CPU in there. The net thermal load isn't favorable.

However, if for reasons defying rationality you decide to try this anyway, you'll need an external power source. USB-C at 5v tops out at 15w, USB3 type A ports can hit 7.5w under certain conditions. Also, laptop power bricks tend to be matched pretty closely to the system they come with. I do not believe they can eat another 100w of load and keep functioning.

How did your Nvidia GPU die? Somehow I don't think overheating would lead to that by itself since they can and will throttle aggressively enough to survive the heat sink falling off. If you want, I know MSI afterburner can lower the temp limit on a lot of GPUs, but that could also eat performance. I live in a place that can see temps in the 30s as well. I also have an air conditioned home though.

Edit: Your punctuation and grammar seems fine to me. I have a French Canadian friend that does the same stuff, which is kind of weird. It's admirable to have picked up another language.

the nvidia geforce died while i was playing eve online on 2 monitors... just couldnt handle it :).. ATI forever...

here is another idea... what if i take a wide heatsink... press the peltier against that and place that under the fan that is on the bottom of my cooling pad, therefore separating laptop and any condensation...
oh and by the way a cooling pad to me is this item that you place under a laptop that elevates it by 5-7 cm.. has a fan that blows air into the bottom of the laptop.. usuallyi poweresd by a usb cable....

and the power brick that powers my beast is roughly half the size of the old vhs cassette if you are old enough to know that... and is rated to 180 watts...

Peltier is not the answer in laptops. You need to add heatsinks and power. You don't have room for the former, or power for the latter. That 180W brick is used to power the CPU and GPU and potentially charge the laptop at the same time. Adding even more load just means you are going to definitely start draining the battery while gaming.

If you want portability and cooling. Quick disconnect external water cooling is what I would do (or just buy a faster laptop)

And no, you can't really stick a computer in a fridge or freezer, they are not 100% duty cycle devices. Soon as the interior heats up and the cooling capability of the unit is exceeded you now have an insulated box for your very warm PC.

forgot to mention that as a proud member of CAF, i fluently speak 10 different dialects.... and in case i havent mentioned it, i currently reside in the Philippines to be closer to my daughter. the laptop is valued at 1500$CAD at time of purchase... very unlikely that you will see me walk around with it in this country.... so although yes.. portable... it is lovingly placed on my desk and will never be moved from that exact spot...

if i cannot power the peltier via usb, that is fine... how about the second idea ? tie wrap the thermo electric thing to a big heat sink... tiewrap wrap that setup under the cooling pad... Theoretically, the fan of the cooling pad will blow cold air up into the underside of the laptop...
dont think the cooling pad fan is strong enough to kick up condesation into the open air vents of the bottom of the laptop.. but i will look now... ... wow.. now that i look at it,, it really is the crappiest cooling pad I've ever seen... the fan... yes, quiet... couldn't even push Calista Flockhart backwards (the anorexic actress that played ally mcbeal)

and no you cannot place a pc or laptop in the fridge.. a Canadian youtuber tried..... maybe you know Linus tech tips ??? apperantly the computer puts out more heat than a fridge evaporator motor can keep up with... but i never mentioned fridge until now

hi welcome back.. heres a thought, pleae remain seated, what if i cut out 1 or 2 squares right under where the cpu and gpu chip are.. and place a liquid cooling block on top of each one.. therefore keeping the bottom panel on there, .. yes 2 liquid cooling systems is overkill but there isnt anything touching betwen the copper pipes for the cpu and gpu... which is Nvidia (sad face).... im sure wtv power cables i need i can find a a usb to that type of cable adapter, how would i secure it in place ? tiewraps ??? wow that seems soooooooooo.. redneck'ish... would i even meed to use thermal plaste ??? hehe.. i mean yes i could simply remove the copper plates entirely but i figure other stuff in that gets toasty too.. like vram.. i dont want to take away from its current function,, just help it along.... no.. i have no intentions of placing a pc in a refridgerator... and if you tell me that a peltier is useless, i will assume that your diploma or knowledge allow you to do so, so how about it.. the copper pipes on both chips seem to be somewhat flattened out.. would firmly placing a liquid cooling block help any ???? however if you know any liquid cooling block that will allow me to replace all copper pipes all together.. MSI GF65 thin UE is the full model.. it has an intel i7.. but a later generation not the first one.. a nvidia 3060... i think it came with 32gb of ram... but with the covid check from our prime douchbag mr Trudeau.. i got 64 gb and added a 1tb nvme in the additional nvme slot.. the power brick seems to be rated for 180 watts... the only way how i know how to find anything is google.ca, so maybe you have another way ???

yeah sorry, evil ppl like me know all the worst forms of torture.... but since i am Quebecer, i tend to stick to the classics and lock someone in a room with Celine Dion music playing at a ridiculous volume
there is NO therapy on earth that can fix THAT kind of mental trauma 😈

okay no answer to the liquid cooling blocks.. i did look up.. rthe BEST cooling pad on our crappy planet.. and google whispered... faaaaantaaaaaaa, weird right ?
no it said liano v12
cn-11134207-7r98o-llx7n0hj4t2a18



according to the information it does not take usb as power.. instead a wall outlet... so my question is... since it is literally forcing air up the underside of my laptop... can the 2 fans inside the laptop get damaged ?

I am not sure the problem you are trying to solve. In some ways it is strange it takes air in from the bottom the way it does since you almost couldn't use it as a "LAP" top. On a desk it should get more than enough airflow.

I would just turn down the AC temp in your house rather than thinking about crazy stuff to cool a laptop. Maybe only some what less crazy is buy a small portable AC unit. This will greatly increase the temp of the room you run it it, unless you hook it to a window, but the air blowing out should be very cool. You could set it to blow on the desk.

Too much heat?

Well...what are the temps now?

i keep speedfan always open and the temps are always below the 100c threshold but speedfan shows this tiny fire icon if anything reaches 70c and that makes me uncomfortable because i love roaming space in Eve-Online for hours... or.. starfield.... i just want to keep everything blue or green, thats it

i totally agree but in the Philippines 1kw costs about 25 cents , even the US is like 10 cents, i really dont mind doing anything crazy as long as it can be reversed... and using Hydro Quebec.. it was more lie 7 cents... i used an actual DRYER for my laundry, i simply did not give a F

PS i have in my dwelling a Boston Bay 550 watt AC unit that keeps my Canadian butt from melting but each time i hear the evaporator or condensor kick on.. i know i just lost 10.5 php... and just that surge pull is roughly 1000 watts.. the rest of the time it is just the fan pushing outside air through the frosted pipes
if i was running my entire pc on solar power i might care alot less.. but the solar panel AND battery, enough juice to run the laptop for 16 hours a day, and that whole thing easily costs 1000$usd
so im kinda building my own loar setup.. i have 2x 50ah batteries giving me a total of 1200 watts.. and im expecting a 600ah batterty which should in theory pick me up over the 7000-8000 watt range if i super glue all the batteries together, my solar panel is quite large and is rated at 320 watts.. ust that alone will gimme enough power to run the laptop and that liano v12 cooling pad and the 5 hdd to 1 USB dock easily......,

phew that was alot of typing.. please just answer this.. is that kind of cooling pad safe to use ? the part where the laptop sits kinda has a foam that makes all air go in the bottom portion of the laptop and nowhere else
