Yeah, especially since no one can get CM4s and Ivan has so many that he can do stuff like this. /s

​@@ronkuhlmeier6414 I was more worried for his fingers than the pi

😂Не свое не жалко

Yes

One of the reasons why i always wear glowes when i am working with a knife - way harder to cut yourself

I actually just did that the other day with a serrated knife :)

Gave me flash backs to when I sliced my thumb open claret everywhere like a scene out of “Psycho” minus the shower curtain.

Still have a scar on my thumb🫣

@@Calthecool only the one. I nearly took my thumb off with a knife and had a good go at my fore finger with a chisel. And yes I do know the rule keep your fingers behind the blade!🚑

💀💀💀

I mean the processor is bound to the lid only by the thermal paste, it would take a lot more that that to break the bga soldering beneath

@@zaydabbas1609 I think its thermal glue they use in IHS

​@@Sphyxx im pretty sure ist just paste on the die and some adhesive around the heat spreader

@@zaydabbas1609 There is adhesive, and it doesn't take that much to crack a BGA solder joint.

@@detaart and once you cut that adhesive, there is only thermal paste, otherwise don't you think it would've taken a lot more effort? If the actual die was glued then sure it could break a solder joint, but there's no way the solder paste alone would do that. Also it looks like the solder paste is fluid cause you can see cavitation on the die/IHS

Yes, at 5000mhz

Water-Liquid COOLING

Dark rock pro

@@gjg_8125 water liquid?? have you ever seen someone do water solid cooling?

Throw away i guess🤣🤣.

​@@the.n00bish I did once, but they got badly injured. Water-gas turns out to be known as "steam", and makes for lousy cooling. #yaymrwhiteyayscience

It’s not that painful, he’s prolly gonna put Liquid Metal on the cpu once he cleans off all the old thermal paste. Then you just put a few dabs of RTV sealant on the IHS after cleaning off the old sealant and set the IHS cover back in place and let it cure. Now you got a super cool cpu so you can overclock it and get way better performance with out the cou thermal throttling. I did this to a brand new $1,200 Intel CPU a few years back and it did wonders, you just gotta be careful when prying/cutting off the factory glued IHS cover. (Overclocking isn’t for everyone tho) but I’ll eventually do this with my new pi 4 that I just bought haha

No real practical way to mount a heatsink to it without risk of cracking the die i think. And not that it would matter. Can't clock these much past 2.2 ghz, regardless of the size of the heatsink.

@@detaart i remember a time where cpus did not have a heatspreader, it was perfectly possible to mount a heatsink directly on the die. biggest risk was breaking off the corners when you handled the heatsink improperly.

@@the.n00bish Sure, but this has no mounting provisions, so you would risk cracking the die pretty easily. Back in the day, the socket clips or holes in the board kept everything centered, and even then it was possible to crack the die.

@@detaart i overclocked mine to 2.3GHz

RIGHT

I want to agree, but i can't on one simple factor, the chip before it didn't have a metal plate and was fully packaged in plastic/resin, but this model and following ones do and they are designed to run without a cooler, however will perform better with one. it's mostly to protect the die because the pi is first and foremost a development/educational tool and they want it to be somewhat robust to physical wear and tear, so capping it with a thermally conductive lid allows for that while still being a good heat transfer medium. That said, the difference with direct to die cooling on the pi is negligible and honestly not worth the effort under normal circumstances honestly.

Stuff like this isn't always because it's best thermally, but it is simple, working, robust, and cheap. Good enough for 99% of use cases.

That is why the adhesive does not go all the way around: it would pop off when the air underneath the -lid- heatsink.

lol exactly

@@sonacphotos Similar to the AMD/Intel right? AMD uses multiple die packages unlike Intel, where they stuff everything into a single die.

@@sonacphotos CPUs used to be like this too. They started with these IHS things on pentium 4s

I'm actually going to say no, the chip doesn't produce nearly enough heat output to even remotely warrant it. it's only a 3-5W chip lol. Yes un-cooled it will throttle, but even with the lid on, a basic active cooler is more than enough to keep it under the limit and comfortably below 50C

@@sonacphotos but the chip on the Pi has a TDP of 3-5W idle and under load, such a small amount of heat output can be dissipated with the minimal amount of effort, i don't think it makes any sense for the Pi at all. but i'd love to see some actual data that proves me wrong.

​@@RonLawsremember, they're also normally inside a housing, and potentially sitting around other, maybe warmish, electronics. And HOPEFULLY they at least have a fan on the housing. But yeah, most common use, in most situations, will prob do just fine..... unless intended to be used in hot environs.... outside or buildings without AC in summer. Just other considerations. 👍

lol no

uhh ... yeah worse lol. you want as little thermal paste as possible.

thermal paste isn't a very good thermal mass. it's a thermal contact material, meant only to fill imperfections on a given die/heatspreader/cold plate surface. Silicon paste is actually a pretty good insulator, if you add too much you'll seal the heat into the die.

That's not the CPU, that's the heat dissipator for the CPU since raspberry Pi's don't have connections on their boards for radiators or CPU fan connections. Some people would just get a regular computer fan and connect it through the pins, but I'm pretty sure this dude was just making hardware gore since delidding a CPU is atrocious for it even when you know what you're doing.

Upgrade the termalpaste

Better than Microsoft's thermal paste . Red ring crap .

@@akfreed6949 No, the interconnects in the chips were crap.

@@stanb1455 BGA with early tin free RoHS solder. Same problems as those nvidia gpus failing on a bunch of laptops back in the day.
