You're likely thermal shocking hardware if you're pulling from ambient to -40 and back again (~60c delta!). Ideally you should bring the chamber back up to ~50c to do a drying cycle before you come back down to ambient to negate the need to leave the system to dry out for a few days. There's a few fluids that you can use for "water" cooling that wont freeze at low temp (Engineered fluids EC110 is a good one - also dielectric). Source: I design military servers that operate in -40 to +55c environments and make a lot of use of a very similar climate chamber!

That glycol looked pre mixed. Since their was water in the loop you probably got no better than a 25/75 mixture. Their are charts for antifreeze to water mixture to temperature tolerances easily available online so you can properly mix the antifreeze for ur car. Just use antifreeze which is designed to known standards and specifications and will produce repeatable results and mix as necessary to not freeze at -40. For -40 you require 52% antifreeze to 48% water mixture to prevent freezing. Premix the solution, completely drain the loop and fill with solution.

Just buy 100% Ethylene glycol and mix it yourself. But I agree, just going from the viscosity of the antifreeze when he was pouring it, it was definitely not just ethylene glycol.

for future reference: glycol on it's own can only go down to -13c but glycol/water mix of 50/50 can go down to -30. as you add more glycol the freezing point goes up again.

You can tell they have never used and enviro chamber before. You have to run a normalization cycle before you open the door! Bring the components back to the air temp of the lab before you open the door. It only adds a few minutes to the testing and you don't have to worry about condensation. Glad they figured it out at the end. Also, you can mix glycol 50/50 with water and it should still work fine for those testing temps.

I was totally amazed how much a good airflow setup can make such a huge difference. Much more than in all the tests - since temps here are so much higher, than in the test setups of reviewer/youtuber! Went from 2 cheap (=shit, since Arctic is cheap too but sooo much better!) in front and 1 cheap upper rear and good but too loud rear out, to 3 F12 front in, 1 P12 rear top in (directly onto CPU cooler) and one P12 rear out. around 12-15 degree difference and almost complete silent, unless I am gaming.

Still, my case sucks ass (it's a generic badly designed one) and I have the stock cooler.

I think you have the humidity and temp thing backwards. The total water the air can hold goes up with the temp, so by heating it first, you likely had more total water even though it was low relative humidity, since that's relative to max it can hold.

@ferrisr

Жыл бұрын

That's what I came here to say too. Heating the chamber increases the capacity of the air to hold moisture, so the RH% goes down, but the absolute amount of moisture in the air remains the same (unless you introduced more when you opened it). This is why humidity is an issue and your AC removes a ton of it in the summer when it's running (because lowering the temperature raises the humidity), and also why indoor air gets so dry in cold climates in the winter (heating the indoor air doesn't remove moisture, but warmer air holds more moisture, so RH% goes down).

I had a daily driver overclocked with antifreeze/water mixture at -15. Worked great as long as the tubes and everything were covered with insulation. Sometimes had to dry it out though.

When I would go to the desert it would often get into the 115 to 120s so I think it's awesome to see stuff like this. I've had more than one phone stop entirely cause of the heat

This is not interesting. My phone dies due to heat in southeast qld aus all the time.

17:20 WTF was that cliffhanger. One of the best videos ever. Love your content guys also great camera work dealings with Linus and editing to increase the shock value.

Condensation should be only a problem if your PC is cooler then the ambient air and not if it is warmer. Reason being is the air has a humidity limit based on how warm it is. So the warmer it is the more water it can hold. If you have that warm air that has humidity come in contact with something much cooler the air will cool in response and if it cools enough to drop below the humidity limit of that air at that temperature then it will release water (Form Condensation) in response. If you take something warm and put it in a cold environment or warm something up in a cold environment that warming of the air makes it able to take on more water and instead will encourage the opposite of Condensation which is drying. In otherwords you don't need to worry about your PC forming condensation in extreme colds. However in this specific circumstance if you do freeze the air rapidly without releasing the moisture first you will get frost on everything in the testing chamber. However the warmer components in the PC will be the slowest place that frost forms. In summery though: -Warm air + Cold Stuff = Condensation. -Cold air + Warm Stuff = Drying or in least no condensation.

if you have a contained volume of air and lower it past its dew point, it will condense. not directly on the parts, as you would get with cold equipment, but you'll get fog, and likely dew on everything. (evenly distributed condensation) if you were feeding it a flow of already cold air, any condensation would have already happened in the cooling process, so no further condensation would occur. Frost is simply condensation that freezes immediately.

@@nwimpney, yep is what I was saying that if it is trapped air cooling it will cause an even distribution of Condensation. But the warmer part of the computer will actually Condensat less technically.

that was the most intense cooler swap i've ever seen

If a video has Alex in it, you know it’s gonna be a good video 😂

I just watched Alex do the tea cooled build yesterday 😅

The best part of your videos is the way you guys struggle all the while working against yourselves and still achieve a great outcome. Canadians really are a special kind of people!! 🤣😂

i need this during summer time.

You were really close to the job of the accumulator. Instead of moisture in the system that would turn to acid, the accumulator stores and traps liquid refrigerant that hasn't turned to a low pressure gas before entering the compressor turning it into a high pressure gas. Getting liquid in your compressor is the number 1 reason a compressor fails, so this is a way to prevent that especially in bigger systems. But it is cool lately you've been kinda doing some research on how air conditioning works on some of your chillers. Keep up the great work.

I'm a hvac guy and I was looking for this comment! I was yelling accumulator before they said it hahaha

Apparently a streamer actually did this in Alaska. And they had the same issue with the AIO so they switched to air cooling which worked and they clocked an Intel cpu at like 6.3 ghz or something

“It’s frosty, Alex!” Kid named Frosty: *literally me*

Every process and sis engineer are like "Did they take any appropriate safety measures?"

Employee being more concerned than the owner of the company... amazing lol

We've had Dell reach out to one of our customers and tell them if we didnt raise them temps in the data center they wouldn't honor RMS's because it was too cold. Definitely surprised when we heard that one.

At least you’re getting a lot of mileage out of that temperature chamber. For a second I thought you actually sent a computer up to the North Pole with long-distance remote tracking.

I feel like the main use for that would be validating producer claims but standardizing testing so you can take outside temp out of the equation

Finally Linus take my advice using a chiller a cooler, nice to see it work.

12:40 why did we change the cooler mid-condensation? C O N T E N T ! ! !

hahahaha, this is fantastic! cant wait to see more shenanigans with Alex. it always seems like when Alex is in a video, its going to get crazy haha

God I love Linus + Alex + access to some silly way of cooling things

Why is this so intense 😂😂 I love it

You know, I used to use environmental chambers, and we had secondary doors with holes to reach in while it's running

I just realised: Could those giant wall-mounted gloves work, or would the temperatures kill them? ...then again, that leaves fine control issues.

I wonder if it would of worked if the CPU cooler was swapped with an aluminum or copper heatsink with no pipes, and the paste swapped with a graphite pad.

So you could use the test chamber as a freaking over and I'm here for it

heat isn't how you remove moisture (water). heat evaporates moisture which increases humidity which condensates back to moisture when the temp drops. you need to chill everything to single digits C or upper 30s F so it does condensate and can be wiped out or ideally drained at the evaporator. just like the water that drips from a car in the summer because the cold air conditioner condensates the humid air and it drains off.

2:50 I swear !!!!!!!!!! It Summer in India and my laptop thermal throttles like hell even a cooling pad wont cool the dam thing. The PC is no better.

you all need to run that test with a non heat pipe air cooler, something like the slightly more beefy intel stock coolers the ones that are triple height and have a big slug of copper in the middle, that way there are no heat pipes to freeze over, and no water or pump to seize up with the cold either, that would be the best bet for running at -40 with it running without issues. pretty sure i saw one of those intel coolers I'm talking about on a video you previously did, might have been comparing intel coolers over the years or something. I know the coolers I'm talking about were meant for workstations, I got one years ago bundled with my i7 970 and it actually performed well enough that the CPU was usable in Aussie summers, though was noisy and I ended up upgrading it pretty quick

2:56 oh linus, you poor guy, watch odisha's Titlagarh instead, you will find regular summer is 50°C 🥴😵‍💫😵‍💫😵

I love that the most concerning thing at LTT is Linus yelling "everything is fine!"

I skipped over this video when it first came out based on the thumbnail and title. I checked it out after watching the overvolted 4090 video from today. I think if the title and thumbnail for this video better represented the lab and the temperature controlled chamber, I might have not skipped it over the first time. This video was excellent. Entertaining, I learned something new, and was on the edge of my seat for a moment.

Ya'll should do a video about ortholinear keyboards vs normal keyboards! Either on this channel or on shortcircuit

You know its a good day when linus puts a pc in -40C and overclocks it
