Question can i use 2 peltier coolers on my gaming laptop ?

[ragez0r]

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.
