So corsair has released a M.2 Custom watercooling block, possibly time to visit a watercooled server with these blocks? Idea about the video is to try and minimize noise and possible temps that can be seen within datacenters.

Recently I got an idea for a RGB case where everything is covered in addressable RGBs with reasonable refresh rate that would allow for animations. I'm an electrical engineer and I even got my first (very small) prototype. Pixel spacing is 2mm and at full power it can be too bright to look at ( ͡° ͜ʖ ͡°). You can interpret it as a display on every side of the case (or at least top, front, left and right). I'm writing now without any significant evidence, because I wonder if it can even interest You.

What if you take the water cooled chair and turn it into a water heater chair and the PC as the heater with something super hot like a 11900k?

3D print a gaming computer case, a gaming chair, a gaming mouse (lol how is that possible), and a case for the water cooler...

gonna need some context here, are you 3D printing minitures, are you printing the full size things, is this meant to be functional...ect

Or are you trying to give ideas to LTT?

It seems like a pretty cool idea, but the chair would not be possible 

[Jtalk4456]

I think using metal for the case would be much better, and I'm not sure if they have a printer that can 3d print metal, let alone something strong enough for that task.

The chair could be done for the most part, but again, not sure if standard filaments are strong enough for that job, and the backing/cushioning would not be printed. Mouse would be pretty easy minus the circuitry, but would be a pretty flimsy mouse, I'd wager.

I think what you're going for and what a lot of us want to see is what he would end up designing. I want a detailed explanation of what he thinks a good case needs, what shape a good mouse should be, what makes the perfect gaming chair. Then we want to see him actually do it. We all have these ideas and preferences we'd like to see and he's the guy who could actually pull it off and make it all

can all work, but with what and in what size.

A chair if they use resin, they could do multiple parts and foam for the pillows and maybe a few parts being metal (screws etc and middle) else most functions and could sort of work? But take a lot of time and resources. A gaming mouse would be cool (frame 3D printed), you could have everything you wanted with USB C, wireless, RGB glow through it etc. if you can get some of the parts like the sensor and a good board to fit in it. Case might need to be THICC for the supporting areas, maybe certain filling or resin might work.

it can work, just not all 3D printed and ofc you would need soft materials too.

But could end up being limited in design like a case, if it's going to "work work".

Hi Linus Media Group and Community,

 

Just thought of cool a idea for a custom build / video. That incorporates a PS5 with backwards compatibility with PS4 and a original fat 60gb PS3 that supports backwards compatibility with PS2 and PS1 games. Water-cooled into one custom made case. To create the ultimate Playstation. Without the need emulation software.

 

I would like to hear the communities thoughts on this?

 

Keep up the great work Linus Media Group!

 

Cheers

Heya!

 

Just wanted to drop you a line and let you know I merged your thread into the video suggestions thread.

How about a PC cleaning video. I know they have talked about water cooling loop maintenance and cleaning the tower. I was more thinking how to clean the whole thing. PC, Monitor, Keyboard, Mouse, deskmat/mouse pad, headset, desk, chair.

that could be nice, since some are easy or too different by design.

But some parts would easy in general, else how easy it is to clean or how to, sadly some brands aren't focused on that and are harder to clean by design.

When Apple first announced the M1 chip with their beautiful, absolutely empirical, claims of performance increase, I thought like anyone else that it was an exaggeration. Fast forward to now, and most mobile chips from Intel and AMD fail to come close to the performance of the M1 machines, and get destroyed in specialized tasks, such as video encoding. The question I had was: why???

 

The common answer I have seen goes something like this: x86 is an old, CISC architecture that uses a lot of power in order to do more generalized and complex tasks. ARM on the otherhand uses RISC magic to do more specialized tasks with lower power. Apple in its infinite wisdom used this to create the ultimate lower tdp powerhouse of a cpu that beats other chips in... general performance...

 

Finding an answer thats deeper than this has proven to be surprisingly hard, and the answer commonly provided feels at least disingenuous. I was surprised to learn that for the past 30 years, there have only been a handful of chips from intel that decoded assembly into CISC micro operations(I lost the source, so feel free to call B.S on that), and have mostly been making RISC chips in order to bring down power usage. If its not because its ARM chips vs x86 chips, then why is it?

 

Its because its ARM chips vs x86 chips. But not because of RISC vs CISC, but because of the choices made when designing the cpu architectures.

 

I want to point out that currently Im talking about general performance. Its true that the SoC design makes things faster in a lot of ways, from shared memory to thermals/power usage to components being closed together, and those certainly help. Its also true that apple has taken to building microprocessors within their SoC's that make specialized work like ML and image processing much faster than using the general purpose cpu cores. What Im referring to is why the general purpose cpu cores are faster than everything else.

 

Im pretty sure it comes down to decoders, and OoOe(out of order execution). Essentially, when the cpu parses the machine code, it looks ahead to see if it can process any instructions later on. If an instruction doesnt rely on incomplete instructions for input, the cpu doesnt need to wait for other instructions to finish, so it starts that one. The cpu can effectively multithread your application(not quite that simple, this hasnt and wont replace writing multithreaded code). The instructions are read into a buffer, and decoders parse the buffer. The more decoders you have the more you can benefit from OoOe. 

 

All modern cpus do this. But the issue is with how. x86 instructions vary in length, going up to 15 bytes. The decoders attempt almost every byte combination in parallel to find the instructions in the buffer. Theres no pointer marking the beginning or end. The results of this is decreased decoding speed, and a maximum amount of around 4 decoders before the computational complexity gets too high to be a benefit.

 

The M1 has 8 decoders. ARM instructions are all exactly 4 bytes, so finding them is as simple as starting from the beginning and counting from 4. Algorithmically speaking, there shouldnt really be an upper limit on the amount of decoders you have, or the size of the buffer. 

 

As far as I can tell, this looks like the most likely candidate for why the cpu cores are so much faster. 

 

The source I found: https://debugger.medium.com/why-is-apples-m1-chip-so-fast-3262b158cba2 

 

I havent found this information anywhere else. The only reasonable conclusions I can reach are either that this article is completely wrong, or no one else knows. If this information is correct, I think it would make for a great LTT video. It can go into depth on some of these topics, and even describe some of what we should look out for in order to determine if competition is on the horizon. What can Intel or AMD do to fix their decoder problem besides switching to ARM? Will they ever be able to make competetive laptop cpu's?

 

If theres a mistake, feel free to let me know, but I think I paraphrased the article correctly.

Im not sure if it does. It explains why its able to emulate x86 machine code faster with rosetta, compared to windows based x86 emulation, but it doesnt explain why its faster at general tasks, even in native arm compiled code. It doesnt answer how differences like this can exist: https://browser.geekbench.com/v5/cpu/compare/7629844?baseline=7632107 . It just shows scores and compares them to apple's statements on performance.

Well nobody can really know since Apple doesn't publish details about the design, so...

They've taken some ARM core, made some changes to it and it manages that, but only they have the details of how and why.

Take a look at the article I linked in my original post. I'm sure it's not the definitive source of truth, since you're right about apples secrecy. But I doubt they are using dark magic, since the actual chip production is outsourced. The thing I mentioned regarding decoding are specific to ARM, not apple.

xspc pump/reservoir repaired with no support from outdated obsolete pump.,,,used a new designed chinese pump 800L/H and it works perfectly. I designed a few part with my 3d printer...Zero leaks and Zero landfill. I am suggesting a 3D printer parts design contest to save at least 1 unsupported liquid cooling system...using chinese parts will be optional.

From what ive found from starting out as a digital artist. Drawing tablets are very important. However from looking I cant seem to find the right one. Mainly because all the video on them are shady promotional videos or just blatantly lying. If a staff member from LTT who does digital art could make a video reviewing these drawing pads to show what is truely the best option for your money. Then it would really help new artists decide which drawing tablet is right for them and help prevent the blatant scams these companies are pulling on people who dont know better. I could give you a few links if needed. Thanks for your time

You can actually liquid cool a PC using a car radiator while it's still inside the car and connected to the engine. I can explain how - and given the nature of how a thermostat works, you can also regulate the overall temperature of the fluid to be below a set temperature.

You could call it "How to LS swap your gaming PC" and the car community would go absolutely nuts over it...

Hell, I'll even do it for y'all.

hi
don't get me wrong but why when logitech G pro x superlight released the whole channel was like "wow, so perfect, best mice in the world" but now that orochi v2 has a way better battery at the same weight, better sensor, multi device dongle &... but there is no review about it.

Air cooling in the system, higher airflow: Use a compressor with 4-5 nozzles in the top og the cabinet, that blows air through the system, like, 2L pr sec (at least double the amount of what the fans are capable of, if you can test that somehow(fan in the end of a tube, airflow tester in the other end)). 

This should do 2 things : Keep the dust out, cool down the system. What if this is a solution to the GPU 30xx series overheating? I mean, it's gonna be loud, but cooled PC!

OR: In extension of your test with the cooling rack from a car, why not just use the fan? It's 12V, and bout the full size of a tower side panel.

Hiya Guys! 

 

Made an account to post this after Anthony touched on HDBaseT on TechQuickie. 

 

I've recently bought an MHub from HDAnywhere, it's going to run about 6 TVs in our new office, I've not got the thing running yet so can't comment on the quality of it right now, but basically I'm hoping it's going to let me hook up a PC, a set-top box and of course a Playstation or something in my comms room and distribute it out to all the TVs. 

 

It's a really nice looking piece of kit, I'd say it's sort of in the prosumer category, the main unit is the profile of a switch and the receivers are little boxes that can hide behind the TV, get power off the main unit via cat6 and connect to the TV via HDMI. 

 

Might make for an interesting one, and I think it's a pretty unknown product category, not much on YouTube about it. 

 

Take care team.
