5 Myths about Watercooling that are WRONG!

"Hell Yea" Let's see that loop order thing...

"Putting water into your computer" sounds exactly like putting a "fire inside your house" but of course, nuance is important and the fire is in a chimney and the water is in tubes.

Interesting anecdote; Both my PS3 and my 360 spent about 30 hours at the bottom of a pool (don't ask), and me and a coworker were able to get them running again by disassembling them, dunking everything in alcohol and letting everything dry before reassembly. That was 11 years ago and both still work.

As a middle aged man with a kid and career, I moved away from water cooling and just invest in higher end air cooling options entirely because if something goes wrong I simply don't have the time to deal with water cooling anymore and I don't want my primary rig down for weeks because I can't find the time to properly fix something. For the same reason I also like larger cases so there is plenty of room to work inside the case.

Mistakes I've made watercooling over the years: 1. Forgetting to put a drain in my loop. 2. Putting a drain in my loop with a T junction that had a super crappy ball valve attached to it that would free spin 360 degrees on the handle part of the valve instead of just going 0 degrees for on and 90 for off. This was fine for years because I was always smart enough to put a cap in the open end of the ball valve before firing the pc up, until the one time I wasn't. The ball valve was at around 89 degrees instead of 90 and it resulted in something like putting your finger on a garden hose, sprayed coolant straight into my expensive PSU, which then shorted out and died. 3. Thinking I would be fine just diluting my loop of premix coolant with distilled water over and over to the point where it was probably 1/3 premix, 2/3 distilled water. Turns out the chemicals in premix are super important and they stop algae growth among other things. Clogged the loop with gross algae schmoo that made me replace 2 rads and my pump. 4. Used Corsair soft tubing. This stuff is garbage that will kink up super easily and impede flow in your loop. I hate recommending EK products now but their soft tubing is the best I have ever used. I will never put distilled water in my loop again unless it is to be mixed at the appropriate ratio with a concentrate. Buy enough coolant to sustain your loop until fluid change time, it's worth it.

Yes do that temperature comparison.

Perspective/tips from someone whose first ever custom loop is now 6 months old: If you're able to afford a custom loop and feel like you're ready to take the plunge - just do it, it's so much fun. If you want to 'dip your toe in the coolant', try doing a simple loop for just your CPU as this will be the cheapest and will still look great, as long as you plan it out well. Also, have fun with the preliminary stuff, like research - do as much as you can, as the success of your build is largely determined by the research phase. Plan out your loop order on paper in a very rough fashion, then when you have decided on all the parts you want to buy, try doing a more detailed drawing of what you hope it will look like - remember, actually building it is nothing like what you plan in your head - I had to make tons of changes due to small clearance issues in my PC case. Before getting over-excited about the build itself, try to think realistically about what you are trying to cool and the overall loop arrangement - I thought I could cool a 4090 and 7800X3D with only one 360 rad, and soon found out what 60 degree C coolant temps looked like! I had to get another 360 and partially tear down my loop so my pump wasn't destroyed (60 degree max operating temp)! The Corsair Lab channel has a great video on loop layout presented by Greg Salazar. Similar to above, try to think about how you are going to control your setup - are you going to use an expensive suite from Aquacomputer? Are you just going to set-and-forget by having your BIOS keep the pump at a steady speed? Are you going to let your fans ramp up and down with GPU/CPU usage, or are you going to add a temp sensor to your loop and have the fans control their speed based upon liquid temps? This area can get really out of hand in terms of complexity, so you might not want to leave it until just after you've finished testing your loop to decide how you want your loop to behave in terms of fans and pump! Look at Jay's old videos on fittings, coolant and build layout - I got tons of info here. Remember the 24 pin jumper for the motherboard! - you need this to test your pump/loop before actually booting the PC (it keeps the power 'isolated' to just the pump so the PC will not boot up, just your loop). Remember to try to add a drain valve to the lowest point in your loop! - If you don't how will you change your coolant easily? Remember to thoroughly clean your radiators before building! - there are tons of videos on this. The time spent washing the crud from the new radiators will pay off in the long run. Do not use the style of pressure tester you see Jay using! - The bike-pump, all-in-one style is very prone to leaking from the pump section and I had this problem. It caused me such a headache because it was my first build and I was lacking in confidence and experience, so I was blindly trusting the pressure tester, so I thought I had a leak when I didn't. Get the 2-part kind like the Dr Drop Pressure tester - the kind where the pump is separate from the gauge! Don't bother trying to mix your own coolant - the amount of comments I saw under the research videos I watched where people were complaining about general gunk build-up, growth in the fluid and damaged nickel plating on the CPU/GPU blocks was crazy - the common factor seemed to be that they were all making up their own coolant. Just get a premixed from a trusted brand. As Jay said, if you want an easier time, just go for rubber tubing - If you want to 'upgrade' to hard tubing later on, it will only require buying new fittings - the least expensive main component in your loop. Take your time with the build and don't push yourself too much, as this will cause mistakes. Leave it till tomorrow if you're fatigued or getting frustrated. This will also buy you more time to think about your build as it's taking shape - most of the best alterations I made to my build were this kind. As I said at the top - just have fun with it and enjoy every step in the process. The research, shopping, planning and building phases are all fun in their own way and you never know when/if you'll be able to do another build (the expense!).

I really appreciate channels like yours that try to give the viewer the confidence that they can do a task they thought was hard and beyond their skill level. I can't tell you how many videos I've watched to figure out how to fix my car, household appliance, or anything else. I've built computers for 24 years and have never touched water cooling until a few weeks ago when I installed an AIO in my system. Upgraded my AMD CPU and the air cooler just couldn't keep up. It was cheaper to get a 360mm AIO than a good air cooler. So thank you for being one of those channels that tries to boost confidence in people.

20:42 Jay's humor when calling himself out for the way he said something is always funny. It was a long day, but this particular line about "or your fingers, well and your fingers" had me laughing out loud for a bit.

A lot of people don't understand that 300 watts of heat is 300 watts of heat no matter what the actual temperature is or in other words 300 watts of heat at 70C = 300 watts of heat at 80C However the advantage of 300 watts at 70C is your CPU or GPU can clock a little bit faster but even that difference only means a couple percent increase in FPS or 1 - 3 FPS which is essentially unnoticeable in actual gameplay.

Once in 2001 I had a PC in a high tower which was on the floor and my dog ​​then decided to piss in to my pc and the cabinet was open so everything inside was completely wet with piss. The craziest thing was that there was power but it wasn't on, I removed the power cable and removed all the cables from it and rinsed it with distilled water inside and dried it. When I turned my PC back on it worked perfectly, I guess it just proves that electronics are tougher than you imagine.

Based on a Jayz2cents video, I sucessully built my first custom loop with bending hard clear acrylic including CPU, GPU, VRMs, memory and 2 360 radiators. 2 years later it is still going strong. Thank Jayz!

Mixed metals and soft tubing loop with dual pumps, 360 and 120 mm rads, the fluid is an automotive antifreeze, de-ionized water and hy-per cool mix, I blast it every few months with an aquarium UV light to sterilize the fluid and kill any growth. It's been running almost 5 years - no corrosion, no growth or buildup, no fluid changes just keep it topped up. Your channel really got me started into PC liquid cooling, thanks Jay!

Jay I water cooled my PC long before anything was available. I made my own parts without any help back around 1990. I just understood that thermal mass is the bottom line. Yes my first time used a heater core out of an 84 cavalier and a fishtank pump. Blocks were all aluminum blocks with fittings drilled in and some fins cut in for passive heat dissipation. No there were no fans on any of it because there was no such thing as motherboard headers. But I could push my system way faster than stock. No temp monitoring in those days so who knows what the real world benefits were. My current system is water cooled also. Nothing fancy expensive it just works.

Watching Jay videos is literally like getting advice from a dad. It has such a warm tone to it with some excellent advice.

Would love to see you make a budget watercooled build - Something with not over the top specs but still enough to warrant water cooling, what value that would be and what performance watercooling a system like that would offer etc. I feel like that would be interesting.

Just got a new case and added a new rad to my loop. No need to upgrade any parts, but I'm glad I got in and added new fluid and cleaned the blocks.. these barrow and barrowch fittings have held up just fine. Reusing parts is awesome

I’ve been doing custom loops in my personal rig for the last seven years and it started with your videos. I watched your videos over and over and over and finally decided to take the leap and do soft to me. I still do soft tubing, but like you, I’ve switched to the black tubing because of the plasticizer issue.

1. Watercooling doesn't make your room colder 2. Leaks doesn't always ruin a system (not using tap water) 3. Cheap options for loop parts now exist 4. LOOP ORDER DOES NOT MATTER (because of the small size of a PC loop and small delta of temps) 5. Making a custom loop is not that hard especially for soft tubing
