Be innovative and don't be afraid to break things! Isn't that how you become a billionaire??

[–] MonkderVierte@lemmy.zip 3 points 3 hours ago (1 children)

Well, for the last... 10? 15? years, it would be just a slow sluggish experience. They under/overclock depending on cooling capacity.

The fan on my previous Intel CPU (bought a little over 10 years ago) went out, and that thing would shut off in seconds from overheating, even without load.

When you use ChatGPT for building instructions...

[–] Mr_Dr_Oink@lemmy.world 29 points 6 hours ago (2 children)

I love that they had the heatsink and fan, they just didnt know where it went and actually mounted it to the case. It wasnt just that they didnt have one.

[–] Rekorse@sh.itjust.works 5 points 1 hour ago (1 children)

I'm sort of surprised it fit on the 120mm fan slot. Maybe they just forced screws through the grill though.

[–] moopet@sh.itjust.works 2 points 20 minutes ago

Oh shit I noticed the exposed CPU but totally missed that part.

[–] verdi@tarte.nuage-libre.fr 7 points 5 hours ago

Those damned unreliable AMD CPUs, he should have gone with Intel!

[–] CrystalRainwater@lemmy.blahaj.zone 44 points 9 hours ago (3 children)

It was long ago but I was this dumbass. I kept reading online people said a fan was optional and didn't understand they meant a case fan not a CPU fan so I built everything and couldnt figure out why it wouldn't turn on. Realized fairly quickly and bought one and everything worked after that

[–] ChaoticNeutralCzech@feddit.org 3 points 2 hours ago

Technically, a CPU fan is also optional but you need to provide some other cooling (water pump?) or accept massive throttling.

[–] craftrabbit@lemmy.zip 3 points 3 hours ago (1 children)

I didn't realise that I need to buy a power supply. I had a fully assembled computer and was asking myself how I can plug the thing in.

Also just bought a psu after and it still works like a charm to this day.

[–] ChaoticNeutralCzech@feddit.org 1 points 2 hours ago* (last edited 2 hours ago)

You can stick wires with mains voltage into any two pins of any motherboard connector but there's a reason they're not shaped like an AC receptacle 💥. Unless it's a ZX Spectrum, that cheap thing used the most basic connector (3.5mm jack) for everything: cassette I/O, video output and, unregulated 9V DC power input from the transformer brick, and people would often fry it.

[–] idyllic@leminal.space 11 points 5 hours ago

Honestly, I am envious of you, as well as the person OP posted above. You did something - learning from whatever source you could find best; having the determination and will to go ahead and sought help perhaps knowing too well you might be ridiculed. Because for the people that know this stuff, it is trivial and not worth of botheration. So the help is not enthusiastic - but for the new doer it is so challenging.

I wish I had the energy, time and courage of you all... Maybe someday I will but until then I can only love and admire your passion.

[–] zergtoshi@lemmy.world 7 points 6 hours ago (1 children)

I once installed Windows on a Pentium 3 without cooler - not on purpose though - and it worked!
Well, installing the OS was on purpose, the CPU being without cooler not so much.
Apparently modern CPUs are snow flakes 🤓

[–] Airowird@lemmy.blahaj.zone 2 points 1 hour ago (1 children)

I think you're confused about how heatsinks work.

For reference: modern CPUs are a lot of hot air. 😁

[–] zergtoshi@lemmy.world 2 points 1 hour ago

I beg to differ. I'm fairly sure I've heard about meltdown on modern CPUs.
Are you really sure they aren't snowflakes?

[–] CoooookieCrisp@fedia.io 20 points 10 hours ago

Stop trolling. No one knows why without a full diagnostic.

Must’ve gotten a faulty CPU that produces heat when it runs.

[–] kamen@lemmy.world 6 points 7 hours ago (1 children)

... as opposed to those ones that consume heat from the environment when they run.

[–] reabsorbthelight@lemmy.world 6 points 7 hours ago

I asked chatgpt to put my CPU into heat consuming mode and it then suggested I mine BTC to equal out the thermodynamics. I'm still trying to figure out where the BTC is, but it's nice to go green

[–] ClassifiedPancake@discuss.tchncs.de 88 points 15 hours ago (1 children)

I used to work as an intern in a PC repair shop and we had a guy come in saying his new self build computer doesn’t work. Turns out he cut a huge part off the mainboard so it fits into the case.

[–] mcv@lemmy.zip 72 points 15 hours ago (4 children)

That's significantly worse. Assembling a PC without knowing what a cooler is for is bad enough, but to actually cut pieces off complex electronic components, I don't know what kind of state of mind you have to be in for that.

[–] MonkderVierte@lemmy.zip 1 points 3 hours ago

It works/worked on some GPUs though.

[–] rbn@sopuli.xyz 7 points 6 hours ago

what kind of state of mind you have to be in for that

Probably crazy enough to demand that the PC repair shop has to bear all the costs he caused by his genius idea.

[–] blady_blah@lemmy.world 6 points 6 hours ago

"but I didn't need those extra PCIE slots!"

[–] roofuskit@lemmy.world 18 points 13 hours ago

The kind of state that would have me refund his money and tell him I'm baffled and can't figure it out.

[–] humanamerican@lemmy.zip 113 points 16 hours ago (16 children)

Most programmers I know wouldn't understand what they're looking at here.

This is sysadmin humor maybe?

[–] 1984@lemmy.today 2 points 1 hour ago* (last edited 1 hour ago) (1 children)

Writing code but never seen the thing the code runs inside of...

I guess they are not very curious.

[–] humanamerican@lemmy.zip 1 points 1 hour ago

I'm sure there are great screenwriters who don't know the first thing about cameras or projectors. They can still write good screenplays.

The CPU is the silver squarish shape towards the right. It generates a lot of heat when in use, so having good cooling for it is important. So important that CPUs come with a fan in the box. This involves a heat sink to help draw heat away from the CPU. This screws on mounting points around the CPU, but thermal paste is also used to help heat transfer up. Then there's a fan that attaches to that heat sink, so that the hot air from the CPU can be blown away from the CPU.

People spend a heckton of money on cooling for their CPU and GPU, because when things overheat, they throttle themselves and performance becomes super slow. Longevity of components can also be harmed by higher temperatures. If it gets too bad, then it will crash entirely.

This PC has put the CPU heatsink on the case fan on the left. I don't think this is especially harmful in and of itself — the big problem is that the CPU is entirely "naked" and has no cooling whatsoever. This means the CPU begins overheating basically as soon as the PC is turned on.

Edit: you can actually see where the heat sink should match up to the CPU here

[–] MonkderVierte@lemmy.zip 2 points 2 hours ago* (last edited 2 hours ago) (1 children)

Ah btw, the thermal paste is only supposed to fill the microscopic surface gaps, so please add only a tiny bit and don't spread it around, it creates air bubbles while adding the sink. A rice corn worth in size and form in the center is enough.

[–] jaycifer@lemmy.world 1 points 14 minutes ago

What is rice corn? An image search just shows me corn kernels mixed with rice.

[–] Korne127@lemmy.world 73 points 15 hours ago (3 children)

Yep. This is hardware related. To be fair, many programmers I know are also into self-building and more hardware-related stuff, but that's something I personally just don't know my way around well (instead I like more theoretical computer science more). So I genuinely don't know the problem here, and I think that's fine.

[–] AnarchistArtificer@slrpnk.net 6 points 9 hours ago* (last edited 9 hours ago)

The big silver heat sink that's on the left is meant to be on the CPU, which is the Silver squarish shape towards the right. Keeping the CPU cool is a big deal — CPUs come with a smaller fan which is sufficient for many people, but people who use their PC more intensively, or want to extend the life of their CPU typically buy an additional cooler. Here's an example of a stock cooler, and here's a motherboard that's using the fairly basic aftermarket CPU cooler that I have. It was only $30, but when I was new to PC building, it was strongly recommended, because if your CPU gets too hot, it'll throttle itself and slow down. People who over clock their CPU (running it at a higher voltage for better performance) have to get even beefier cooling, such as water cooling. You can completely fry your CPU if you do something wrong when overclocking, and even if it doesn't get that bad, minor mistakes can cause crashes due to CPU overheating.

So TL;DR: keeping your CPU cool is super important for both performance and longevity of the CPU.

The PC in the top photo has zero cooling for the CPU. Not even the stock fan that comes with the CPU. That heatsink that's attached to the case fan is almost certainly intended for the CPU — you don't even need a heatsink in that location.

This means that this person's CPU will rapidly overheat soon after it is turned on.

Edit: you can actually see where the heat sink should match up to the CPU here

[–] humanamerican@lemmy.zip 58 points 15 hours ago (2 children)

You get no shade from me. My only beef is with programmers who act like they are experts in all things computer when they aren't.

BTW, the issue in the picture is that the CPU cooler is attached to the wall of the case instead of the CPU. It shuts down because modern hardware will usually turn itself off when it overheats to mitigate the risk of permanent damage.

[–] anton@lemmy.blahaj.zone 5 points 3 hours ago

I thought that was the cooler of a different component and the cpu just lacks one. Now that you said it, I see the CPU footprint on the cooler.

[–] waldfee@feddit.org 11 points 10 hours ago (1 children)

Some old cpus would actually go up in smoke if you ran them without cooler: https://youtu.be/Xf0VuRG7MN4

At least the thermal paste isn't too thick..

[–] thagoat@lemmy.dbzer0.com 85 points 17 hours ago

Must keep the fan cool!

[–] Imgonnatrythis@sh.itjust.works 13 points 13 hours ago

Tell them to switch to water cooling. You will get an even more awesome picture.
