LinusTechTips just shared this video a couple of hours ago. It proves that those spending money to reduce room temperature through water cooling are simply wasting money.
Watercooling should focus on extending the life of the hardware and keeping the hardware cool. Air conditioners should focus on cooling the room.

I don't know why people would think that watercooling is going to reduce your ambient room temps. Yes, it's keeping your components cooler, but it's still gotta dump that heat somewhere. Unless you run your water loop to a radiator outside, all that heat is going right into the room.

Exactly. It is good to show that it is tested by someone they would trust to show them that it doesn't matter.
It seems that a lot of times people trust youtube over users in the forums, so this would be good for those individuals.
I know for a fact that running watercooling doesn't reduce ambients. My room is always toasty, lol.

Good info Scarlet! I am reminded of our folders who say "Fired up folding to heat the house" , and some actually used their folding rigs instead of the heater. :)

It's simple physics. Heat out is still the same wattage, in fact it will be slightly more because of pump heat. Water is just a more efficient heat pump. I don't see why he took the time to cover this, it's a very simple concept.

Here is a nifty diagram I drew up to share with your kids about the wonderful process of GPU cooling. As you can see, there are no magic places where the heat disappears; it is simply transferred from one medium to the next and still ends up warming up your room. Though I suppose the fans only assist with the transfer by circulating the air, but I'm not going back in to change it lol  Cheers to physics....

If you look at the strawpoll, 20% of people thought it would cool their room down. He posts these videos because people ask questions. Why would he need to cover any other the stuff he covers if people just open Google and ask it? Because people don't open google, they assume it works how they want, and then when they are wrong, they get upset.

If we ignored the repeat questions on the forum, we wouldn't be considered one of the best forums around.
If he just ignored his users, he wouldn't have so many that follow him.
Many of his users are very young and are in the millenial mindset that everything must be provided, and he is providing answers for them.
There have been users on our forums that assume something will work and it doesn't, and people here take the time to type out the answer for them... look at Sajin, who is always doing that over and over.. this subject can be equally equated to the NVIDIA game promotions, and everyone assuming that because they bought an EVGA card that EVGA will provide the code, even though the answer is plastered everywhere constantly explaining that isn't how it works. They still assume it does. All it takes is less than 2 minutes of research to see the answer, and yet.. the won't take the time to find it.. but they trust the youtube videos.

The room temp will equalize out to be the same if not warmer from water as you are able to pull more of it off the card. What you do NOT have is the crazy hot spot you get from a HOT air cooled card venting out the back. Concentration of heat is different so it feels less intense which I think is where some people can make the assumption when they don't think it all the way through.
The other half has said for years that in winter if her hands are cold, she puts them next to my PCs radiator exhaust and warms them right up, granted she does complain that they don't warm her like my 8800 Ultra or my 480 did :)

It's simple common sense.
Reminds me of when I was going to school for electronics and we were asked to find resistances for a cube made with 1k resistors
a to b
a to c and c to b
I did the math in my head and gave all 3 answers. Teach says no no no it takes a complex math equation.
If you think of it like water going thru pipes from point A out you have 3 resistors in parallel simple equation next step again 6 in parallel and so on after doing the parallels you then add them up in series and you have your answer.
No need to complicate the simple
in both cases here you have fans blowing heat out into the room its an even simpler solution than that cube, something that little illustration shows

I'd never even heard someone claim this before... anyone that claims watercooling reduces room temps doesn't even have a high school level understanding of physics  Now if someone wants to watercool their room or house, that's what an evaporative cooler is for.
 Have water, will cool.

Since water is more efficient at removing heat from your components I would think watercooling would dump more heat into your room. I don't really pay much attention to it myself but I do notice that as my room temperature rises from Folding it begins to affect my temps inside the PC exponentially until it levels off.

Off course reduce room temperature... my computer is in smaller room not living room and I have H100 and dual cooler card... When card start to blow hot air ambient temp in case go up to 70-75C 100%, than all hot air start to go up through roof and H100 and after 20min I start to feel much hotter in that room than in other. Or if I open side panel it's same. That's only one card, I could imagine with three reference example... that's like little heater on back side of computer. Off course water don't allow to temps go so high and ambient temps are lower. I doubt air from radiator blow air with similar temps as reference cards example on back side of the case.

E=I*R. P=I*E. A cool watercooled card actually consumes slightly more power than a warmer aircooled card. This has been proven multiple times on video card review sites (such as Techpowerup) when they measure the card's direct power consumption and compare cooler aftermarket coolers to warmer stock coolers. Therefore, the cool watercooled card is actually releasing slightly more heat into the room constantly. A hot aircooled card is hot because its heat isn't being released into the room. You can't say that a 80c card is making the room hotter than a 50c card. It's opposite. The only reason the hotter card is hotter is because it isn't releasing heat into the room as fast. As it remains hot, it is consuming less power. A cooler card which is consuming slightly more power by being cooler and is more efficient at removing heat, makes the room slightly hotter -- even though the card is staying cooler. Make sense?

It makes sense to me. The waterblocks are removing an additional 30°C and sending it into the room through the radiators making the room hotter in my opinion. IDK why people are so high on mechanical keyboards. My L and M key have been double typing all stinking day. I spend more time editting my posts than writing them.

But you say that room is hotter if fans easy blow 55-60C and room become more hotter than when fans blow 80C in room. Put fingers behind water radiator and behind TITAN X under full load. You can't put fingers close... warm air will not influence on room temps worse than hot air. He could increase room temp but influence of 55-60C on room temps will not be so big as influence of 85C. I doubt in good watercooling loop temp of any object pass 55C ever. Simply water in loop not allow to temps of liquid or air from radiator increase on 60-65C. And room better accumulate such temps than blowing 85C from reference cards with 3000RPM. It's more complicate than you think on first ball.

I was wondering about this, I know that (electrically) conductive materials conduct better (and lose less energy to heat) the cooler they are, but on the other hand, semi-conductive materials work the other way around. add that to the fact that heat (I think) is needed too switch a semi-conductive material from non-conductive to conductive, and a hotter card would be closer to the switching point(provided a high switching point), and wouldn't need as much power to switch and do it's task. Correct my possible science if I'm wrong, I've not really studied it all that much, more like read something in wikipedia that I may or may not remember correctly (or somewhere else, don't recall)

Air cooled GPU -- dumps heat directly into ambient air, efficiency determined by heat sink & fan The fans push ambient air through the heat sink and the heat transfer warms the room. The heat sink is 80 C, so that heats the air. Water cooled GPU -- dumps the heat into the water. Then the radiator dumps heat from the water into the ambient air. The energy loss in water cooling is the BTU needed to raise the temp of the water. The fans push ambient air through the radiator and the heat transfer warms the room. In this case the loop maybe goes 60 C (probably less) and that heats the air I'll take a 60C heater over a 80C heater, if the goal is to keep the room cooler.

The "air heater" isn't 80c. Put an infrared thermometer on it. Prove me wrong.  The point is that the die is hotter in the air-cooled video card, but the aluminum fins on the air heatsink are slightly cooler in temperature compared to the aluminum fins on the radiator with the same fan and same room temperature. The only reason there is a difference in core temperature between the two is because the air cooler doesn't transfer heat from the core into the heatsink as efficiently. With the air cooler, more heat is staying in the GPU and less heat is escaping into the room. They both heat up the room virtually equally, but the water-cooled system heats up the room slightly more overall because it releases heat from the core more easily and consumes slightly more power (due to operating at lower core, memory, and VRM temperatures) and thus it is always consuming slightly more power than the air-cooled card with all other things being equal. Now, with GPU boost, this is more true than ever. It is physically impossible for the air cooler to have a hotter heatsink than the water cooler and have a hotter core temperature at the same time, with all other things being equal. It's a contradiction of logic to think otherwise.

I'll simplify it a bit. Wattage x 3.14 = BTU/hr
Regardless of your cooling method (heatsink/fan vs radiator/pump) just measure what your power supply is drawing, and that will tell you how much "heat" is being dumped into your room by your computer. Measure what your video card is drawing and that'll give you the BTU's for that specific card.
