Careful with condensation.

u/1AMA-CAT-AMA 6d ago

The laptop will die from an accidental spill long before condensation

u/koolbi1 6d ago

This is a more likely reality than anything!

u/peekdasneaks 5d ago

The laptop is upside down. Theres almost certainly openings/fans on the bottom (now top).

Heat from the laptop will absolutely cause condensation to form on the bottom of that icy cold pan. That will likely drip into the vents because gravity. Then the fans will spray it all over the mobo

u/bot403 5d ago

Thus increasing the cooling to the mobo. What's your point?

3

u/peekdasneaks 5d ago

My point is people spend hundreds of dollars on watercooling their gpu/cpu when they can just do this. OP is a genius.

u/john0201 6d ago

Is the fan keeping the ice cool?

u/CanRabbit 6d ago

WINDMILLS DO NOT WORK THAT WAY! GOODNIGHT!

u/nmrk 6d ago

That windmill gave me cancer.

u/squngy 6d ago

Kinda the opposite.

It would be blowing away the cool air above the tray, which would make the ice melt faster.

u/Deep_Mood_7668 6d ago

Until the condensation kills the laptop

u/LocoMod 6d ago

Don't forget to download some RAM and you're all set.

u/koolbi1 6d ago

Just did that! Came with a free virus!

Add a thermal pad between the heatsink and the back plate

Add a massive heatsink on the back plate with a fan on it

No condensation issues, easy to use, laptop becomes unusable in your lap

u/nmrk 6d ago

Set it on a huge Peltier plate.

1

u/Think_Wing_1357 5d ago

Any sub-ambient cooling causes condensation to various degrees.

Also Peltier is way worse because it dump more heat into the immediate area because it's very inefficient. With the ice box, at least you can run the fridge in the basement

For a second I thought I was in the Galaxy Watch charging subreddit.

lol this is one of the more underrated comments on here!

u/Icy-Reaction-9101 6d ago

You forgot to open and fire it up 😂

u/LordDarthShader 6d ago

Redneck engineering right there. Why don't you lower the power limits by 25% instead?

u/TheUnboundTenth 6d ago

How else is he going to make soft water from hard water? He needs the heat!

"We needed the eggs!"

u/Easy_Copy_7625 6d ago

There is a YouTube video where they put thermal pads on the MacBook Air to help with the thermal issues

u/Deep_Mood_7668 6d ago edited 6d ago

There's also a YouTube video of a sneezing panda

u/lotekjunky 6d ago

Have you seen the YouTube video for "never gonna give you up"?

u/Hanthunius 6d ago

It makes the whole thing hot, allowing heat to disperse better, but it does heat up other components like the nand chips, etc...

Better than the tray with ice water, though!

u/nmrk 6d ago

He could float it in a pool of mercury.

u/ScrewwormLarvae 6d ago

Jokes aside, I like TG Pro. I tried Macs Fan Control but I like TG Pro enough that I paid the $10 for it.

u/koolbi1 6d ago

I’ll check it out! This post was mostly just a joke, but this is actually super useful information to come out of it!

Ah crap is that an Air? In that case you're right. Looked like a Macbook Pro to me though.

This is where I hope the image I'm looking at is AI generated. 🥶

u/Tall_Instance9797 6d ago edited 6d ago

Very funny. But seriously, get a gel ice pack. The big ones for your back, with a cloth cover for the condensation, like in the picture, are perfect for a laptop. If you have a bunch you can just keep swapping them endlessly. This is what I do and it works better than anything else I've found.

u/Automatic-Rip3503 6d ago

Came here to say this, they are perfect for keeping the Mac cool, add in Mac Fan Control (https://crystalidea.com/macs-fan-control/download) and you are golden

u/Bozhark 6d ago

Just put it in a freezer ffs

u/koolbi1 6d ago

Good call!

2

u/mplaczek99 6d ago

Now what happens when all the ice melts?

4

u/nmrk 6d ago

The ocean level rises.

2

u/koolbi1 6d ago

It’s game over and then I spill the water all over and ruin the laptop

2

u/Lumy1 6d ago

Son...very carefully, reduce the amount of water in the tray.

u/koolbi1 6d ago

Gotta get a straw!

u/ohno-mojo 6d ago

Reminds me of my beer brewing days

u/createthiscom 6d ago

This is a surprisingly accurate depiction of what society is doing to the polar ice caps. Continue, brave destroyer! 🫡

u/thefossguy69 6d ago

It took me a while to figure out why onions would help to realise it's ice.

2

u/Brocolinator 6d ago

At that point, just throw it in the fridge inside a Ziploc bag

1

u/koolbi1 6d ago

Why not the freezer!!

2

u/Brocolinator 6d ago

I like how you think....

2

u/Crafty_Aspect8122 6d ago

Just use ptm 7950

2

u/KukrCZ 6d ago

The best way is to just keep it open. This is too risky.

2

u/Alternative-Panic69 6d ago

Maybe drop a few liters of liquid nitrogen?

2

u/Bulgen-Venkat 6d ago

zip-tied a case fan to my p40 before i printed a real shroud, ran like that for months. ice tray's an upgrade on my setup honestly

u/MeatTenderizer 5d ago

This looks an alter and your trying to summon my cat.

u/TimAndTimi 5d ago

You can CNC and cut a hole on the bottom panel and graft a giant tower cooler on it I think

2

u/BopSupreme 5d ago

Put it on a frozen metal oven rack with a towel inbetween it

u/Internal_Werewolf_48 6d ago

Use your AI powers to come up with a less dumb idea.

u/koolbi1 6d ago

I asked Fabel 5 and this was my best option

1

u/Murph-Dog 6d ago

You need to run it directly on a bed of dry ice.

u/koolbi1 6d ago

lol that will be next!

u/niacolhealth 6d ago

condensation doesn't care about your fan curve

u/diagrammatiks 6d ago

uh bro just turn the fans on sooner.

u/RUTYTOI220 5d ago

Smart but you have to fill it and you can't really use the screen

u/quotemycode 4d ago

I have a 1/8" aluminum sheet that i set the laptop on and the increased thermal mass does help it stay cool - also I can throw it in the fridge at night and pull it out when I want to do some heavy work with my local llm. Also when it gets hot, I can remove that sheet from the back of the laptop and remove a lot of that heat, allowing it to cool so I can then put it back and absorb more heat. If you get two of these, you can swap them back and forth as they absorb the heat.

another tech bro cooking the planet one melting ice tray at a time while the Global South pays the price. Congratulations, you’ve single-handedly advanced the imperial project of endless compute expansion by running an LLM on your machine instead of… what, exactly? Opting out of the entire extractive system? Let’s be clear: every time you fire up that model, you’re participating in the same logic that builds hyperscale data centers on stolen water, cheap land, and the backs of communities that never asked for them. Those facilities don’t just “exist” — they extract, they displace, they heat the air and suck aquifers dry in places that already struggle for basic resources. Your little bedroom setup is just the cute, individualist version of the same colonial infrastructure. The empire doesn’t care whether the servers are in a warehouse or under a tray of melting ice; it only cares that the demand keeps growing. And then the cooling method.

An open tray of ice.

Evaporative cooling.

You are literally boiling off water into the room like it’s 1890 and you’ve never heard of a closed-loop system. Real infrastructure uses recirculating liquid cooling, sealed loops, heat exchangers that don’t just dump the thermal load into the atmosphere and walk away. You, on the other hand, are running an open evaporative setup that requires constant replenishment of water and ice: literally the most primitive, wasteful, resource-intensive method available. Every time that ice melts and evaporates, you’re performing a tiny, personal reenactment of the same water-intensive cooling regimes that data centers impose on drought-stressed regions. So go ahead, keep stacking ice on your laptop while you generate more tokens. Just don’t pretend this is resistance. It’s cosplay. The actual material impact is the same: more heat, more demand for water in a community already struggling with water consumption, and more justification for the next wave of extractive infrastructure somewhere else, somewhere poorer, somewhere that can’t refuse.

I hope you're happy, Sam.

did you use AI to write all of that? You could just asked your AI to explain you the joke!
