This will probably sound like "back seat driving", but a thermal pad would have solved a lot of the issues you came across :)

[@TheMadJoker87]

...but.... he has to sell that "pro" thermal paste...

[@ARRW4]

The problem was that the button was a lot higher thank CPU, and you would not want to put thermal pad on CPU if you removed ihs for thermals in the first place

[@unstablenl]

A lot of this to me felt like a typical case of overengineering. Nevertheless, it's fun to see people go the extra mile.

KZbin is cool because people who post advice (good or bad) are engaging with the content and giving ideas. good ideas or bad ideas!

[@FISHYFILMPRODUCTIONS]

For anyone who wants to use a stock pi5.... the temps are fine. His testing was a little disengenious. The stock ihs helps quite a bit as opposed to the die just being expoosed to air. Thermal pads are also much easier to use to fill gaps.

[@MrHeHim]

And if you want to be lazy there's also thermal gel or puddy, which don't run. If you don't want to guess the pad thickness. You see it as that bubble gum colored stuff on many GPU's. Some types also act as thermal adhesive to avoid mounting mechanisms. Furthermore, he didn't need to use exotic filament like CF-Nylon as ABS (like most PC components) are already made of for a reason. But yeah, the guy is building a bike and ended up with a jet engine powered pedal assist with gyroscopes to help balance the bike. Still only a 3 speed and Walmart tires. Even with the 1.1v 3.1GHz OC I'm sure the water loop didn't even need to have the pump running... At this point I feel like Moleman from the Simpsons, I want my 5 minutes of my life back

[@FISHYFILMPRODUCTIONS]

@MrHeHim I'm a firm believer in doing something just because I can, but I never pass it off as something that is needed. To his credit he did mention that it isnt necessary, but that was at the end of the video already. The custom case and everything was cool. I just don't like the attitude of "you have to this to get the most out of it" you really don't.

[@aurelienlux]

But does the IHS help mostly by adding extra thermal mass, meaning it’ll still reach similar temps but it’ll just take longer, or does it really help dissipate the heat. Because I’m not sure that a basically flat piece of metal like an IHS really radiates much heat so I would assume that it mainly provides some extra thermal mass rather than extra dissipation. But I could be wrong. And of course you can always stick a small heatsink on the IHS which will help dissipate the heat, even more so if you pair it with a fan as is commonly included in good Pi case kits, but you’re still limited by the size, and fins density, of the heatsinks you can physically mount on a Pi as well as the size of the fans (and the air volume they can move). I know from experience they provide enough cooling for most uses, even without a fan you can already get pretty okay performance (and the Pi shouldn’t fry itself since it has temperature limits), but there is little doubt in my mind that you can extract more performance and even some overlocking headroom with a better cooling capacity. Whether you need it or not is another question but if you truly want to get the most performance physically possible then you probably should look beyond the typical small heatsink and fan combo most people use with commonly available Pi cases. Although even then you probably don’t need to break out the small PC sized watercooling setup (though if you’re gonna go through the trouble of watercooling then why not) and you most likely don’t need to custom build a CPU block lol

[@FISHYFILMPRODUCTIONS]

@aurelienlux oh your absolutely right, to get more performance you will mostly likely need better cooling. I didn't do a good job of articulating my point. I apologize. What I was trying to say was, if you just want to emulate retro games, the stock ihs is fine. And I think you are correct that the ihs just adds more thermal mass as opposed to actually cooling it. A heatsink would do both.

[@Zyxlian]

Distilled water is actually the best liquid for heat transfer, with no additives at all. The coolant that is sold in pre-mix solutions has glycol, anti-biotic and anti-corrosive agents mixed in to prevent freezing and blockage. All of these additives *reduce* the effectiveness of heat transfer. Since this Pi (and most PCs) is not going to be in freezing temps, the glycol is useless. Anti-corrosion additives are not needed if all metals in the loop are the same (a lot of loops are a combination of aluminum and copper, but it is common to get fully copper watercooling loops). Anti-bio additives are the only thing that are necessary in most loops, unless you want to swap out the liquid and completely clean the loop every few months. You can buy small bottles of anti-bio additive for this purpose.

[@stevencoad9224]

Came here to say this, I run just distilled in my loop (cpu/gpu/2rads), I change it about every 9-12 months and have never had any issues.

[@Zyxlian]

@@stevencoad9224 When I built my loop, I went through a few pre-mix brands over a couple months, I finally just bought some biocide. I dumped the small bottle of biocide into a gallon of distilled water and I have not had any debris in the loop for around 6 months now. Glycol is the worst thing for a loop, and I genuinely believe the only reason they use it in pre-mix solutions is to sell the cleaner that you need to get all of the glycol stickiness/smell out of the loop.

[@danielsimpkins9662]

A number of things to note here. A. It’s pronounced like “bottosarah” or, more phonetically “baw-toe-sarah”. B. Your overclock only was active on the pi install. When you installed Batocera, that wiped the overclock. It’s a software overclock, and not a persistent hardware overclock. C. Thermal pads would have been a better choice for thermals transfer. D. As another has said, your 84 degree temp was rather disingenuous as you had the IHS removed. That little plate actually wicks away a decent amount of heat. D. You should have installed some kapton tape on the cpu where where there wasn’t direct die contact. There’s a number of onboard caps and resistors that are almost the same height of the cpu die. Your heatsink plate doesn’t stop from over tightening so you have a very high chance of shorting out the cpu since you removed the IHS.

[@Maulana_rhodes]

Yes, he is not a very intelligent person typical over privileged American

[@TheDainerss]

I am glad someone else noticed the overclocked issue. As far as I know Batocera does not allow you to provide software level overclocking. RetroPi would have been a better option as, I believe, it relies on the same files to provide a software overclock.

[@namirahnaf711]

I am sure your initial temperature would have been much more reasonable if u still had the stock ihs on, 88c at idle is ridiculous

A few years ago, I got curious after watching those fishtank PC builds, so I took my RPi4 and modified a plastic tub, got 2 small fans, filled the tub up with non-conductive liquid, hooked up the fans, with them side by side, one push the other pull. Surprisngly, it worked just fine, one day I will do it again, but next time, a custom case. :P

[@ayushdebnath6435]

[@tarakivu8861]

I mean you could have just taken a board with an 5105 or even just an N100 for cheaper and fully complete with cooling. The Pi5 is wayy to overpriced for the hardware, The Raspberry Makers are out of their minds. You can buy a full mini PC for the same price with less hardware issues and better CPUs with more build-in features.

[@rhysjones8506]

I remember like 10 years ago when the pi was about education, they'd bring Pis to my school to teach us students about coding and programming. With the steamdeck pushing emudeck it has made emulating much easier now. Even a cheap phone is a better option now for emulation but pi videos still do well it seems

[@mickymurder]

[@axescar]

If you don't search for hype on topic "water cooling RPI5", and really search for something that you said about retro emulation beast I know some variants. 1st one is Radxa x4, it's if you want/need RPI size. But I'd rather go and buy ASRock X600, took mini STX board of it and use regular AM5 water block it top of Ryzen 8700g. You steel will need to create custom case for all of that, and all that will be in similar volume case to your RPI5. But overall performance will be "a little" more that RPI5 😊

[@TheDainerss]

Someone already mentioned this but it needs repeating. The moment you wiped the Raspian OS, all your overclocking was removed. Remember, you were setting your overclock in config files in the OS. You were running Batocera at stock speeds. RetroPi would have been a better option as, I believe, it has the same configuration files as Raspian OS since it is based on it.

[@nidhu595]

instead of support interface, try using water-soluble filament to go between, it dissolves in water and leaves a beautiful finish with no risk of breaking the print while removing supports

Oh god lol your attempt at integrating the sponsor into the video lol😂. Still better than i could do.

I jumped the Pi/Retropie ship this month. I know you used Batocera which is also good. I have been using Pi's since the early 2's for emulation and keep buying new ones all the time. I refrained from the 5 as I would be about $500 total into Pi's. So what does one do? Well, FPGA! As we speak I am building my MiSTer and getting ready to rock. Retropie/Batocera are awesome and so is the PI, but it just takes so much time to configure everything. And, emulation is great, but hardware recreation is even better! Still, great vid as usual!

[@budthecyborg4575]

8:36 Most computers won't even run the BIOS without a heatsink, and without the heatspreader you'd never even get it to post, but the RPi5 here is running at the full stock 2.4Ghz just bare silicon exposed to the air! That is one crazy efficient chip.

[@kulilin3104]

Not sure if anyone else has mentioned this. But I'd strongly advise against using K5 Pro. I ran it in a gaming laptop and after 6 months of use, I noticed massive temp increases on my VRAM. When I opened up the system, I noticed massive pitting and bubbling in the K5 Pro accross all memory modules. The K5 Pro had literally boiled, seperated, then congealed. It left pock marks accross all of the laptops VRAM modules that wouldn't come off with 99% IPA. Upsiren UTP-8 thermal putty is a much better, and cheaper, alternative to K5 Pro. I had a significate reduction in temps on VRAM after using UTP-8, compared to K5 Pro. There are many other people, way smarter than me, that have done extensive testing with both putties. UTP-8 comes out ahead in every test.

[@xMeatMusket]

At the end of the video, what borders do you use for your emulators? I really like those! Also, AWESOME video, what a cool project!

[@BlueHairBro]

This might sound a bit strange, but I think older games look better at low resolutions. I feel like they kinda hide imperfections from the hardware of the era. Great build tho. I love how you add such flair to these projects, and make them feel more than just an emulation machine.

[@termiterasin]

I've always wanted to do some crazy insane cooling. Like desolder every single I/O piece, solder extensions for critical I/O like the power, USB, ethernet, and video, then coat it in liquid electrical tape or conformal coating. Then dunk it in dry ice cooled isopropyl alcohol! At that point the PCB is naturally going to cool the CPU from below by its thermal mass alone. I don't think there's a better way to cool a raspberry pi!

[@jacoavo7875]

Video idea to follow on this one - do another case, possibly the same dimensions as the one in the video, that interfaces / sits below the Pi-console. This box could house another PI, or an extension to the PI above, and could house an additional fan, plus storage / other hardware so you could expand the features of the whole system. The two 'boxes' could then be either one system or two and be customized to be anything you would want. Like an emulator + NAS storage, or router + NAS, or whatever anyone could think of :D.

18:14 I noticed some Z axis artifacts. Make sure your Z axis grub nut is very above torque spec for that kind of fastener. If you have a Z axis screw put the grub nut in the shallow part of the thread. Grubs have rounded heads and naturally feel tight while having slip specs lower than torque would indicate. I think a problem with modern 3d printer design is the tiny surface area of coupler grub nuts lets high torque small movements slip on the metal surface. You get acceptable performance but have these visual imperfections caused by z axis lifts that don't complete. It really really needs to be very tight for the most consistent Z axis layering. Z axis moves the least with the highest torque impulses, moving the whole print gantry.

The n97 intel CPU is a real good choice for emulator projects and the n100 and n200 are not quite as good as the n97 but are decent.. the rpi5 should play a good 50% of the ps2 library of games!! Also using different backends other than direct X like volcan or something emuelec support multiple backends same for botacera and ppsspp and psx emulators.. so saying ps2 doesn't work is not true it does!!

Also using SD card is a huge part of the problem 60MB,s at its best isn't fast enough get a nvme hat for the pi and boot from that!! Or on a pi4 the USB 3 to SATA SSD board will increase data speeds by 100's or MB per second and nvme hat's 1000's MB per second!! Running a OS or games off a SD card is just way too slow and not even close to fast enough data speeds especially random reads and writes..
