Thanks for another great video Jay. I love the advice about vaping. An old engineer told me that back in the 80's, computer pros were accustomed to the "no smoking in the computer room" rule. This was from the previous experience of smoke tar actually slowing down connections and causing irreversible bugs. Not really an issue today, but defintely telling.

1. Don't interchange PSU modular cables 2. Don't plug/unplug components with the PSU powered on. Switch it off at the back or unplug from the wall. 3. Don't vape or smoke near a computer. 4.

Note on the potential leaks on water cooler system. (I'm a plumber ) put a water detector that sends a message to your phone if water is detected. The more expensive the device the better chance of it telling you earlier rather than later.

Thank you for finally covering the PSU modular cable issues. Now why do they NOT have a standard.

[@nanoflower1]

Probably because there's no need (from the PSU manufacturer's perspective) for a standard. Sure, it would be nice from a customer side, but no one is going to buy one PSU over the other because the cables are standardized. It would take someone like Intel to step in to force the standardization but there's no reason for them to care what happens on the PSU side of the cables.

[@Jules_Diplopia]

@@nanoflower1 on the contrary. Modular PSUs are generally more expensive, they are touted as the top of the line. With that expectation, we, the customers, should expect some sort of standards After all, the wrong cable then becomes a major Safety issue.

Yeah cigarette smoke isn't just particulates, it has various vapours including tar and nicotine. Buy a house from a smoker and you will have to strip the paint, throw out anything permeable (window coverings, carpets, underlays, etc.), and scrub all surfaces. That includes all the ducts and air handling equipment. And wear PPE while doing this - good mask, gloves, disposable coveralls - because what you are dealing with is concentrated carcinogens.

Even if you unplug the power, there's still power for a brief time and if you just start pulling stuff out or install something... same thing can happen.

I also have no shelving in there. Air can get in easily, when door is open and pc is on. Air can get out easily, because nothing but the desk is above it (quite a bit of space in between too), and a huge opening in the back.

It doesn't matter what their power supplies do on the inside or outside. The only difference is how they lay things out for their wire connections. If they adhered to a standard just like there is now for pinouts for the ATX power supplies, then if someone had older cables leftover, they could use those instead. This is the same as standard network CAT5 or CAT6, serial ports, RS422 ports, and so on. To sum it up, they all need to use a set standard for pinouts to the connectors. Simple, Pin 1 = +5, Pin 2 = -12, Pin 3 = Ground, etc.

I've had to clean plenty of PCs from my past clients where the motherboard and other components had a film buildup of resin coming from the incense, causing the parts to fail. Component failure was even more likely when the air became humid (during or after it rains, etc.). The humidity and resin buildup from the incense will actually corrode the circuits and boards and eventually cause a short circuit. Also, the resin cannot be cleaned with any kind of chemical or product.

Good point on the water cooling. That's exactly why my server is air cooled. Dropping the temp a few degrees is great but it's not worth the risk in my opinion. Especially since my server typically doesn't have the cpu pegged at 100%. Uses cases may vary of course

[@michaelmonstar4276]

To me, the point of liquid cooling is never that it cools better, but that a radiator-configuration spits the hot air right out of the case, rather than keeping it inside first, with a hot GPU, while it's waiting to be transferred outside with some kind of airflow. - Of course, for a server that won't be as much of a problem, as it usually doesn't have a raging GPU inside that needs all the cooling it can get. - But generally high-performance PCs do and need to get rid of that hot air as quickly and efficiently as possible. But a server needs to be left alone and be reliable, so it makes sense to keep it away from any liquids and potential failures.

I have an AIO in my PC and I leave it unattended all the time. Honestly, even if a leak did happen while I was using it, I probably wouldn't notice. I'm not staring at my tower when I use my PC, I'm staring at the monitor. And even then, chances are pretty good that any leak would either be immediately catastrophic (in which case it wouldn't matter if I'm sitting right next to it or not) or it would drip in such a way that it just exits out the bottom of the case without hitting anything important (in which case it also wouldn't matter if I'm sitting right next to it or not, the liquid might ruin something on my desk but the PC itself would be fine until the loop ran dry, and then it would probably shut down from overheating). Granted, I also don't keep my PC in an office where I might not see it for days at a time either. It's in my bedroom, and even if I don't use it I have to walk right past it multiple times a day, so there would be plenty of opportunity to catch a non-catastrophic leak.

In the case of a leakage with a watercooled system - my guess is, that it makes no difference if you are there or not in most incidents.

[@japekto2138]

Modular PSUs come with bags to store parts in. I keep the PSU cables and documentation of a specific brand together in each bag. Also, no water-cooling for me. Air-cooled is the closest to maintenance-free PCs. The rest are time-honored practices I've done since my first DIY. Also, an additional practice I do is skip overclocking. The last time I had a real NEED to OC was with the original software-based Quake. I stopped after 3D cards and GLQuake came out and the game was very playable.

[@usefulidiot21]

Instead of simply calling it overclocking, I like to think of it as tuning your components. Because it's possible to lower the voltage of your CPU or GPU (referred to as undervolting) and end up with lower temperatures. And for those components, you can sometimes increase performance while lowering the temps, compared to stock. Though for RAM, when you tune that or enable XMP, the voltage goes up and so does the temp, but I wouldn't consider that anything to worry about and it's generally always worth doing in order to hit the listed specs for it (but going much above the XMP voltage can be risky).

[@perwestermark8920]

It's common to forget that the 5Vstb voltage is expected to be always on. So even when the computer is turned off, the PSU has a side circuit for 5Vstb so that the computer can have wake-on-lan, wake-on-keyboard etc. And one side effect here is that inserting an expansion board can result in the computer turning on the PSU fully. Some motherboards has a LED explicitly showing 5Vstb, so there is a LED still on when the computer is off. It's there to warn that it isn't safe to plug/unplug boards. The normal 5V/12V/... are off, so no power to disks etc. But the 24-pin connector has this 5V live. And 5Vstb is sent to all card slots. And that's why it's important to remember to disconnect the cable and then have the juice run out of the PSU.

As an enthusiast who has only built a couple of aircooled systems in his time, usually preferring even basic watercooling to air, I will say that there is a great deal of salience to the last point.

As an engineer who is used to continuous uptime low maintenance environments, my preference for watercooling seemed insane to him. He went as far as to say he would never mix liquid and computing. As enthusiasts, we have the luxury to be present during uptime; but we should draw the line between uptime and offline time at the extent of our presence.

[@anonymousperson015]

Really glad to see comments contradicting Jay on leaving systems unattended. I guess if you're only using your system for gaming you're less likely to *need* to leave it unattended, but there are many of us who have legitimate reasons to want to run a system for weeks/months/years: should water-cooling just be an out-and-out no-no for those builds?

[@BriBCG]

Agreed, that point was a bit ridiculous. Maybe it might be good practice to use air cooling if you're going to leave your system unattended often, but realistically speaking I doubt the probability of a leak killing your system is higher than the large variety of other factors that could cause your system to fail.

[@HupfderFloh]

The thing with water cooling is regular maintenance. You inspect it (are there wet spots around fittings or radiators, are there indications of degradation on the tubes etc). You perform regular maintenance (renewing tubes & liquid every few months) and of course you thoroughly test it after each risky activity (maintenance, moving the case...). Lastly, some external monitoring with emergency shutdown may be sensible. Relevant anecdote: ran a system without any maintenance for 10 years. So yeah, it might work if you're lucky.

[@JeighNeither]

@@HupfderFloh Meh. There are no moving parts in a water-cooled rig, so there is nothing to maintain beyond any other PC. Renewing tubes & liquid every few months? Are you nuts? You clearly don't have a water-cooled rig. It's a sealed loop, there is zero water loss. And then you say you ran one into the ground for ten years? You're just typing to hear yourself click. You simply use quality parts, & build the rig properly, & you have little to worry about.

[@HupfderFloh]

@@JeighNeither "no moving parts", suure... Basically you retain all the failure modes from an air cooled system and then you add many more (pump failure, clogging, corrosion, dissipation, thermic pressure changes etc). With careful setup and proper initial testing, sure, the failure probability is low and you could very well get away with it for a long time without issues - see my anecdotal evidence. Also if you know what you're doing™ you can certainly engineer a very reliable system (looking at IBM z15, for example). However as an amateur, I wouldn't trust my rig running unattended in my parent's basement while I'm out on vacation. The renewing of tubes and liquid parts is mostly for aesthetic reasons, but inspections are necessary e.g. to reveal bent tubes after moving/modifying something or check for sediments, improper water levels etc.

Well, less than a year later, that AIO decided it was a piece of crap and should act like one. It leaked all over my GPU and pretty much killed my system. Had to replace the GPU, get a new CPU cooler, and replace the PSU because it decided to die as well. I reached out to Origin for any form of support, but they ignored me for a couple weeks before telling me there was nothing they could do. Moral of the story: Don't trust Origin, don't trust cheap AIO's, and air cooling is superior.

But water cooling in terms of cooling performance is just superior. AIO's leaking is something that you have to live with. And it's pretty much the same as any other part malfunction that can happen to your system. You can't make sure an AIO won't leak as much as you can't make sure that your power supply won't suddenly decide to spike the voltage briefly for whatever reason for example.

@JayzTwoCents Good tips. On 11:00 - 12:00 something to clarify. Hot air is less dense than cold air and when air expands it creates positive pressure. If a PC case is in a closed space, like a cabinet, even if the door is opened or it does not have doors and the back is open, hot air will heat nearby surfaces, they will radiate heat back to the environment and the case panels. The case(inside and outside) will get hotter and hotter because of the hot air loops back in the system and the heat radiation of surfaces. Then the air will get hotter and hotter and less dence, lowering it's mass per volume results in it's heat exchange capability getting lower with time. The system will overheat sooner or later.

Weirdly enough I once, years ago, had extremely convenient, one might say considerate, failure. I had three hard drives, basically every drive in the system, fail within two months. But they failed in such a way and order that I lost zero data and ended up with just moving my data to a mix of SSDs and larger hard drives. Of course I still lost money but given how big an upgrade moving to SSDs is and how lucky having multiple hard drives fail without data loss is I am not complaining. In case anyone is wondering one of the SSD advantages is that they do not cause a large transient load when they start up since they do not need to spin up anything. This matters when you repeatedly have multiple hard drives connected to the same power circuit spinning up at the same time. This is the original reason people advocated leaving PCs on. Not really relevant with SSDs and modern power supplies I think? Just do not connect a bunch of hard drives to the same thin wire. IIRC servers started using staggered spin up years ago. It is a SATA feature but not sure if all consumer systems implement it.

I've left custom loops unattended for weeks at a time, never had a leak. Still good advice.

[@ReluctantCriticDude]

Ultrasonic cleaning will twist and break small leads going to pads inside integrated circuit chip. This happened to my companies manufacturing department when they wanted to clean up boards from soldering.

[@andersmalmgren6528]

I've had custom loops for 25 years now. Never had a leak. I even went away for a week this x-mas and let the computer bake some Projects acoustics. 100% AMD 5950x utilization for a week. Zero problems! :D I have had "leaks" in the form that water evaporate out of the system faster than it should, but never a leak, leak of liquids leaving the system.

[@wootle]

Great video thank you Jay. While I can never dispute with how well liquid cooling works I will never go near it - precisely because of the risks you mentioned. Noise from a PC does not concern me and gimme all the big slow RPM fans in the world but nope to liquid cooling!

[@timmanboy1]

It's not that bad. I have been using AIO coolers for the past year. Most likely thing to happen is the pump failing.

[@KrytonTechnologies]

As Gabriel also replied it typically isn't bad. You do run significantly higher risk on custom loops than with AIOs. I've run water cooled AIOs from Corsair going on about 4 years straight without issue in both my system and my wife's system. I do run air cooling on my server that runs 24/7, but I need the water cooling for the massive overclocks we run on our gaming rigs. We do sometimes leave them unattended, however we try to shut them down at night and when we aren't on them. I've never had an issue, but you can have issues and you should be mindful to mitigate risks. Don't be afraid to move to water cooling if you want it quieter or need it for overclocking, but don't feel like you have to switch if your air cooler is getting the job done well.

[@megachonk9440]

I've been running CPU AiOs exclusively since 2013. I've never had one fail or leak. Realistically, if an AiO is going to leak onto expensive components, you probably aren't going to catch it in time even if you're there. And even if you turn it off, it will still leak and the next day you fire it up and... well, you might really fire things up. If you're really worried about it, non-conductive cooling fluid can be purchased, though with an AiO you might have to get crafty.

[@Fireholder1]

When I'm working on a PC that has previously been powered (i.e. not a brand new build), I like to plug the power supply into the wall with a modified power cable that has the two power conductors removed but still has its ground pin on the male end. Then, before I do any work, I press the PC's power button a couple-few times so any leftover juice in the system is expended.

[@rustykoenig3566]

Talking about leaving the system running when your not around.. I have left mine running for YEARS.. but then you mentioned the water cooled system and I can understand that, and just might be the exception to the rule lol. The only catastrophic event I've EVER had with my systems is that one time a fan on one of my graphics cards took a crap on me when I was gone long time ago. Came back to no display and soon as I got close to the case I could smell "that smell" and I got lucky it didn't burn anything else out beyond the graphics card.

[@tomasrosalesr]

Instead of using different pinouts on the MB side they should have just used "passthrough cables". Use the same MF connector on both sides. Like extension cables but for MB's

[@teznick]

this video is so much needed for ppl just getting into pc building , learning from pros like Jay who already have made all kinds of silly mistakes

[@RobertEmery]

Also handy reminder for those of us who haven't built a system in years, thinking about a new flight sim

[@chrisguli2865]

The problem with modular PSUs is that there is no standardization at the PSU end, only on the end point connectors. As such, each manufacturer can change the pinout at their whim. The PSU connectors are basically standard MOLEX connectors, but the pinouts can be all over the place. I just got a modular PSU for my new build thinking great if the PSU blows I just have to swap out the PSU with the same brand, but that is fraught with danger if the new PSU is a new GEN from same maker with different pinouts and POOF! there goes your system. So if you have an older modular PSU that needs to be replaced and only new GENs are available, the advantage of modular cabling is negated. Hopefully PSU makers can at least stabilize their designs to last at least 5-10 years.

[@Sgt_gh0st]

It's just fkn insane... imagine in the future when people have PSU's and cables lieing around and someone ask for spare parts... how the hell was this allowed to happen, blows my mind.

[@markcorrigan3930]

Easy, lack of regulation. But freedom eh

[@TobiasHarms]

@@markcorrigan3930 not really a question of regulation so much as no standardisation. ISO standards, for instance, move slowly and while they are working the companies have time to invest in their own products. This leads to fierce fights regarding the final version of the standard. Change of pinout for a companies own products though I really can't get.

[@Sgt_gh0st]

@@markcorrigan3930 but what's stopping the companies to gather up and agree on a different plug :S

[@Lemming1970]

I don't build many systems, but it never crossed my mind that different PSU would have different wiring!!

[@infeedel7706]

Thanks from Down Under Jay'. Really appreciated one of the earlier vids in this series with regard to 8 pin power cable to GPU and am now running dual cables and leaving the PCIe slot idling under 75W. #1 So this one is rather apt again particularly for the aftermarket sleeved cable I purchased a week or so agao now I'll be checking very closely the pinouts from the Seasonic Focus to my motherboard! #2 Very close to installing my first custom loop :o

[@TheRealSeiferoth]

I know the power supply thing is true. But, before I got my first modular PSU, I thought the whole point of modular PSUs was a universal system so that you could just buy whichever cables you needed. How wrong I was 🤷

[@iikatinggangsengii2471]

no they dont, each cable and psu has their own specs so unless you know what youre doing then just buy same/made specifically cables

[@iikatinggangsengii2471]

although many modders use custom cables just fine so sort of correct as well

[@Anlushac11]

LOL at smoke in computers. I used to work in a computer repair shop. I have put on rubber gloves and vacuumed and scraped tar that had absorbed every spot of dust in the computer. I wore the gloves because I was worried about getting a contact high from literally brown layers of tar.

[@vamp4997]

I did a windows update once before I went to bed. Woke up in the middle of the night and the computer was still on. It froze during the update and I had the push the power button to shut it down. Had fun the next day restoring Window, it got corrupt. :)

[@swampyemerson8269]

Yeah the psu off thing is really important. I have a specific use case for needing my system to power on when AC power is restored. Once when doing a cpu swap, I forgot to power off the psu and I saw sparks under the cpu as the system tried to start. That cpu is now dead.

[@CairnOwO]

Did that with my 1070TI years ago
