This tool could save your PC's LIFE!!! 

The ending should have been Jay screaming like a girl underneath the table when he blew something up with an air compressor.

Jay coming in with the Shorts. Very good job, guys! I enjoyed it! Hoping more to come!

Saw one instance of a guy who did the initial pressure test, no air leak. Started to fill and his loop started to leak fluid. Drained, check checked O-rings, and for burrs on the tubing, all of which were fine. Did another pressure test but let it sit over several hours with a time lapse camera. It revealed a very slow air leak. What the guy deduced was one of the pipes he cut was literally no more than 2mm too short. Cut and bent a new tube that was slightly longer, which did fix his problems.

We use this for Hydronic systems all the time. I strongly recommend waiting a full hour to be absolutely sure. Also! Take a picture of the gauge before and after; if the needle moves even a little, you’ve got a slow leak somewhere. It’s also a good idea to get a leak check compound like Snoop but applying it in a PC will be tricky… CueTip maybe? *EDIT* For anyone curious, over pressurization will break your fittings/tubing. If you go over only a psi or two, you’re fine but if you max your gauge, you’re asking for it lol. These PC valves are most likely nowhere remotely near Swagelok quality so don’t push your luck. Happy building!

“Go play some games.” Something tells me someone would actually do that without water in the loop while waiting to see if the loop holds air or not.

Alternative - Fill the loop with novec fluid, yes it's more expensive, and requires some additional components, but it is electrically safe, and non toxic. Fluid cooled systems tend to be high end highy value, so is £60 worth of safe fluid and additional parts that bad an idea??? And it won't corrode, gunk up or ever need servicing.

Handy tip! But it also highlights why I've never bothered with water cooling. The extra maintenance and points of failure just aren't worth the hassle. I haven't overclocked a CPU in years, so give me a set & forget air cooler over a water cooler, any day.

I was expecting to see a throwback of the radiator blowing up with the compressor, but the big boom works too! I think the Shorts format is awesome, hope you have more great ideas soon

Was the end there part of an ifixit sponsor spot? 😂 (Explosions). Btw your ifixit spots are hilarious with the over the top "action" stuff.

Honestly, the fact that shorts help a channel grow and a re perfect for these quick bits of knowledge from Jay is a great thing, love your stuff Jay :D

instructions unclear, pressure increased after leaving it alone

Please do more shorts like this Jay!

The other option is deionized water. It's the same as tap water except incapable of conducting electricity.

For anyone wanting to use these, most of them will leak after a use or two. That's why using the drain valve is perfect. You can just shut the valve when it's up to pressure. When the time comes, open the valve and check if the pressure remained approximately the same.

The very first watercooling part I bought is one of these. It allowed me to buy used parts and test them without building a loop, and also to experiment and learn before introducing any water.

We do this for our diesel tractors when inspecting and repairing the coolant system. It's good science.

I'm a plumber, that how we test both gas lines and water line on a new system we installed. Good advice. Can work on old systems.

Finally! a short in my feed worth watching 😂😂😂

I might have to try this, I usually just hook up a separate PSU with the 24 pin jumped with the pc unplugged, and wing it. Never had a problem yet, I usually do the blow test to see if it holds pressure

There’s also that neat leak prevention system that LTT tested the other year. Though, it was like 150$, so a little more than the glorified bike pump

to answer the question, if you go past the green you're just over pressurizing the loop. It should be able to handle a bit more pressure, but you could force a pipe / tube connection loose

JAYS DOING SHORTTTSSSS LETS GOOOOO

Jay is just the best. love you guys

if it's your 1st loop I recommend using green UV fluorescent liquid, if you set your rgb to blue it will do a lighter UV type effect anb make the green shine, this helped me detect a small leak as I found dry green stuff around my bottom rad fitting

Jay will make the most useful and funny shorts I'm sure

You don’t need explosions to make Jay look like a mad scientist. 😂 Still a scientist, so my respect never wavers.

First short!! Congrats!!

I'd give more than a few minutes, 30 minutes to an hour. Here's the reason: unless that dial indicator is high fidelity (there are some, but they're stupid expensive) you won't notice a failing system in a 10 minutes, not on that dial. Leaving it longer (AND MARKING IT, very important, with a piece of tape) makes you certain beyond doubt.

Nice Short. I got a solid 20 seconds in before realizing that I had never seen y'all post one before.

I have this but from aquacomputer..it a must tool when you make a water cooling custom..its recommend to test the air leak at least 5 hours, if theres no leak..the loop its safe to fill it

Fear of leaks is why I only use AIO water coolers, I could fill the loop with deionised water but still, the fear persists.

May that CRT always be in frame.

I like how it loops from an explosion to “WEEELLL watercooler can be scary.”😂😂❤

safe for some years, and depending on temperatures rubber can degrade, metal and tubing expands over time etc

I can’t wait for more Jay shorts

Hahahahaha the ending, dude you are the best😂😂😂

Awesome! Thanks for the tip before I build mine!

THIS SHORT WAS EXACTLY ME!!!! thanks jay! i havent made anything yet, but its deffinitly one of the bigger worries. though im planning to use a AIO on the cpu and air on the gpu but mannnnnn its tricky!~!!

I like the how the logo on the top left looks

Joyz shorts are hilarious! Maybe not the ones he was wearing after the explosion! haha

I like this quick and informative style of short well done Jay & Team

This was a dam good tip there😮, I'll definitely be using if I get around to watercooling my pc.

Love this short jay do more of these!

So my first ever total water cooled system leaked bad. Thankfully I was using nonconductive coolant and the only thing with power when it happened was the pump because I knew enough to not power up the actual system before I knew there was no leaks and the lines were filled. Though because of how I built it I could not easily run the loop outside of the built system. Leak happed around the radiator in the top of the case so it got all over everything. Wiped everything down with about a whole roll of paper towels. Found and took care of the leak. Cleaned some of the components with alcohol and let everything dry out for about a week before cleaning with alcohol again. The motherboard was stained blue a little (same for the wooden kitchen table) from the die in the coolant but I ran that computer for about 6 years after that and then gave it to a friend when their computer died and I was upgrading. They used it for another couple of years before they eventually upgraded.

Love you guys!! Thanks for the tip!

Don't want any leaks ? then do this connect the circulating pump to pull the the coolant through the cooling system the out put goes into a bucket put something on the bucket not to seal air tight but to keep stuff out of the coolant now there should be negative pressure in the cooling system no leaks

Id definitely recommend leaving it pumped overnight to really test for leaks. Some could be super super small, and you wouldn’t know after 15 mins.

and this is when Jay and nick invented the first ever PC nuke and went into hiding

checking for leaks as youre plumbing tubes and fittings is great but dont forget to close all the drain and fill ports as youre filling it >< ask me how i found out

This is how we test fire suppression systems (sprinklers). Air first and after water after.

That is beyond awesome!!!! Always go past green!!!

Even on my EKWB Airpump, the green zone is too high! The manual states 0.3 bar, while the green zone goes up to 0.5. Therefore, it's important to exercise caution. The recommended change rate is no more than one line in the first 15 minutes. This is typically due to the expansion of tubes and similar factors. Please don't misunderstand it as one line every 15 minutes. 😂

I found one "used" for cheaper than on EKs site. It turned out to be brand new and sealed.

THIS TOOL COULD SAVE YOUR PC (static jpeg of Jay smiling)

I most got choked with my coffee!!!! 😂😂😂

The end looked like the ultimate IFIXIT add.

Wait what ? Jay does shorts ? Awesome =)

jay going past the green gave SoCal the fate it deserves

OMG. Somehow I saw an explosion coming when he started to pump fast. 🤣🤣🤣

Remember when checking for leaks of your system add 1-2 psi depending on how big the system is. never go over your psi rating by 4 or more as you will create a leak. If it holds over your rated psi it will hold at your psi rated psi

No, custom water-cooling can be scary.

The explosions should have been a segue into a World of Warships sponsor spot lol

Lmfao famous last words. "Let's find out"

That air pump looks like the air pump for mountain bike shocks

Or, just dont overclock and use air cooling. The money you save, you could have just bought higher end parts and gotten probably better performance anyways at stock settings...

Get a aqua pump ot has a bunch of failsafe functions incl leaks, punctures etc a little pricey but if building a expensive pc well worth it.

That's a very special message from iFixit! (You forgot the logo, but I could hear you *say* it over the explosion...)

Watercooling scares me a little bit though it may be another rite of passage when the time and TDP comes.

That was great! Thanks for the info. No idea these existed.

Funniest short in ages. Cheers for the laugh 😂😂😂

This short was a 💥blast💥, litterally~ 😂

bro just told us information some of us won't ever need

Ending is directed by Michael Bay for sure lol :D :D

Just have to say the end was just so damn funny props to the writer

Jay was overly casual with that pump. I wonder what other pump he might be using regularly 🤣

I had a leak once. ONCE. Flex taped that shit real good, didn't leak anymore. I'll never let that meme die. Bite me.

The Ending 😂😂

Jay turned the state of Nevada into a smoking crater 😂😂😂

Love the ending. 😂

I think corsair leak tester is the cheapest out there, I have one and it works great, I would highly recommend one. Just sit there and think hard about what would happen if there was a leak and your entire system is kaput, I bet you'd kick yourself for not buying one.

Great recommendation! That ending was hilarious!

I would be careful with the term "safe". A couple years ago texas found itself experiencing a Minnesota winter for close to two weeks. No power, no heat, and a water cooled expensive animation PC froze, splitting the plastic water block housing. When power came back on the system fried itself.

Leak warranty is one of the on;y reasons I still use AIOs

After that explosion I was honestly expecting a "Sponsored by iFixit"

Yea unless u have faulty piping in which case pressure build up is gonna eventually create a fountain inside ur pc

If you leave the PC and it gains pressure, RUN!

That ending was great.😂😂

Jay farted and the town wiped out in a blink of an eye

What i learnt from this short; the pump giveth and the pump taketh.. all hail the mighty pump

Great ending - thanks. Twist: after testing for no leaks and filling with water - a leak develops :P

Aqua Computer Leak Shield is the best tool.

You guys 😂😂😂! I'm dyin' again!!!

An iFixit kit will fix the puter. Probably not Jays glasses though 😉

Let’s see you do it like a German car and vacuum fill the loop. I’ve wanted to try it since doing the cooling mods in the e63 wagon

Modern man of the modern short video craze❤ Youdah man!😮

can't believe that Jay has master short before any tech youtubers~ XD

That was EPIC!!

For now.. until the seal degrade

I built my first custom loop earlier this year - almost didn't spring for this but I felt so good to come back to find the air still in the green. Only problem is I couldn't figure out how to use this with the corsair ball valve fitting, I don't think that fitting works.

I just double or triple check every single fitting I have, make sure to tighten enough that I almost need a tool to tighten anymore then I know it works great afterwards 😂
