A friend would do this with his Apple M1 laptop when we would play something online. He'd take some frozen fresh cheese out of the freezer (in a plastic bag) and put it under the laptop. Otherwise, his framerate would crater. Sometimes, in winter, he'd put a coat on, open the window, and play with the laptop on the window sill. Apple laptops tend to be slim and silent, but their thermals always seem to pay the price.

oh! Something to test against this issue: https://forums.macrumors.com/threads/m1-m2-flickering-ghosti...

Earlier quoted context omitted.

Opening it up and vacuum cleaning the fan from dust also can do wonders with old and "broken" laptops as a first step. Tiny bit of WD40 in the fan mechanic is the next, then thermal paste, then replacing parts. (Advice, prevent the fan from spinning while doing vacuum)

WD40 - Nooooo! It gets gummy. Use a proper lubricating oil. Or replace the fan. "Pro tip:" Do not direct the output of a strong air stream (e.g. the kind used for automotive work) at the fan as it can de-blade the fan.

And if you do that anyway, don't be a dingus.

Disconnect the fan cable from the socket so that the motor doesn't send pulses of energy back into your laptop. It probably won't harm it, but better safe than sorry.

Small world, I used to work with this guy. If you're reading this Adam, they never got back to me on the W2. I ended up having to call the corporate headquarters.

Smaller world, I also used to work with him. And just recently used the fridge trick on an old dying hard drive (it worked fwiw), but don't remember if he was the source of why I thought that might work.

Smaller smaller world - I work with him today!

Motors have flyback diodes. Otherwise they'd burn out things every time they turn off

It’s funny but I’ve done something similar with putting my laptop into the oven for a short period as it wasn’t getting any charge at all and I guessed after trying everything lose that the board where the power connector was misbehaving. It actually worked after but it was pure luck I think. Another time I did it with a graphics card that had been overclocked and definitely was having some board issues, took it apar…

> reseat the solder and it was working fine for a few months after but obviously none of these are long term solutions

This is why I want to eventually get MiniWare MHP30M Mini Hot Plate

Not in most laptops they don't.

"You will find those fans are brushless DC fans, they are controlled by an inbuilt driver circuit and as such do not need a flyback diode."

My laptop was once heated inside it's case, it was hard to touch it. I don't know how it didn't explode, it was so hot I decided to put it in THE FREEZER. I thought I'd leave it there for 5-6 minutes, but I fell asleep and forgot it THE ENTIRE NIGHT. 7-8 hours. In the morning I panicked as I remembered what I have done. It then had a black screen for a few minutes and I thought I was drowning in my stupidity, but lat…

I dont understand how come condensation while de-freezing didn't damaged the components, but if you spill a bit of water in the keybord might damage the laptop, what brand was that laptop?

It was HP if I'm not mistaking.

Marble flooring in homes is quite common in India.

Its very common in loads of countrys - or at least terra-cotta tiles: Spain, Mexico, Italy, Greece. Its a good way to keep a house cool in summer.

terracotta tiles is a different matter from marble

I have done this. Many years ago I was forced to work with a terrible laptop. It was one of those Dell 5cm thick things that were basically cramming a desktop cpu and gpu into someting that looked like someone had bolted a second box undeneeth a standard laptop. Fans ofc screeming loudly all day. So I had the brilliant idea to just run everyting of an external drive so that when I could work from home, I could seamle…

> Fans ofc screeming loudly all day. Once I worked in a small office and we used ancient but silent servers and we needed new ones. We had a rack in one of the rooms, so without thinking I bought two new rack servers. Worst decision ever. They were screaming loud. You could hear them in all the offices. Temperature in that room went up to 45°C. In the end we could store them somewhere in a closet and ignore the noise…

The massive noise difference between brands, models, and generations of rack servers is astounding to me. I have five rack servers in my house, not in a closet. Three are Dell R620s, one is a Supermicro X9, and one is a Supermicro X11. The Dells are 1Us and by all rights should be screamers, but they aren't. The Supermicros are 2Us, and while they weren't screamers, they were loud enough that on the one that's on 24/7 (the X11), I swapped the PSUs for quieter models, the CPU fan for a Noctua, and throttled the case fans. When the X9 boots up to ingest ZFS snapshots, you can definitely tell it's there.

I used to think the R620s being bizarrely quiet was because homelab loads are understandably small, but then one day I got well over half the cores to 100% sustained doing something, and it didn't get any louder. I know they _can_ get loud, because at boot the fans go to 100%.

I grew up in a city with temp reaching 48 Celsius in the summer Of course this wasn’t very good for electronic devices and hence every console I bought died with a year of over heating. For my PS2 I managed to extend the lifetime by placing big blocks of ice in a tray underneath it and the console sitting on top on a rack to avoid contact. I had to replace the ice every hour but the system worked well enough till the…

When I was a kid, I modified my (shitty, generic beige) case by cutting a hole on top, mounting a 120mm fan, and ducting it with PVC dryer duct to fit over the CPU's HSF (which I think was an Athlon XP 2000+). Airflow dynamics aside, it worked like a charm, and knocked the CPU temps down to ambient.
