Would a aftermarket cooler keep your room cooler or not? *poll*

[Mussels]

If an aftermarket cooler reduces the CPU's temp compared to a stock cooler, then it stands to reason the increase in room temperatures will also be lower.
I certainly feel the difference if my system is running at 80C or 65C.

i forgot to specifically reply to this part:

The way you describe that has two interpretations and i really want to clarify this with precision:

1. Your CPU load goes up so the heat goes up - this WILL make the room hotter
2. CPU temp goes up because of any other reason (dust in heatsink, fan slows down, etc) - can not make room hotter.

I feel like people confuse those two situations a lot, and/or think they're the same.

In practical terms it's the amount of heat that is being exhausted is what makes the difference not the cooling itself, in other words if you have plenty case fans and the hot air is pushed out of the case very quickly it will increase the room temperature faster than compared to a scenario where you have little airflow in your case and most of the heat will remain trapped inside it.

In absolute terms the same amount of heat will be dumped in your room regardless of the scenario because of physics , but since it happens more slowly it's less noticeable and not as much of an issue.

Thermodynamics 101. If you plug an air conditioner into the wall in a sealed room, will it cool it down?

Sealed room, no exhaust. How could you measure the temperature change?

"Sealed" for my also implies no energy via an outlet. The moment the AC kicks in it get's even warmer because the AC is working but has no way to exaust. And that working AC is generating heat itself.

If case is well ventilated it will make a sense...u will feel cool air to your feet and coming from pc

... i am truly stunned how many people dont understand this. is there a simple youtube video or something we should be sharing on facebook lots "YOU WONT BELIEVE WHAT HAPPENS NEXT?"

I am too. Then again, I was a bitcoin miner. If I didn't have a good grasp of thermal dynamics, my house would've burned down years ago.

The way some people write here, they seem to think their pc can become an exaustless air conditioner.

fans can move heat and cool humans through evaporation (still just moving heat, but it 'feels' cold) - since water is bad for electrical components, we cant use that same method to cool computers.

Regardless of what hsf youhave the processor is still creating/outputting the same amount of heat, the only difference is how efficient said heatsink is at drawing that heat away from the processor, so it won't make a difference to the room temp using one from the other hence 90℅ of the poll choosing same...

 

[Komshija]

There would be no difference. Processor will generate the same ammount of heat which will have to "escape" somwehere; meaning that cooler will "consume" that heat and fans will blow it out of the case. It doesn't matter whether it's water cooling or air cooling...

 

[Iceni]

The same amount of energy is transferred.

Here is the problem.

The Stock heatsink runs at 90C. The After-market one 45C with more airflow as well.

So If you are near the PC the 90C + lower airflow will affect more of the air near you.

The after-market one will draw more air and only heat that air to 45C. So the same energy is spread into a greater volume of air, So the perceived temp change near to the PC will be smaller.

Ima guess half didnt read or comprehend your explanation. Yep some pure LOL.

Most already know this but a PC room may also need to be set up in the same way you would set up your PC cases! Inlets and out lets ( For the PC room ), normally the closer you set up the inlets and outlets for the room to the PC or PC's the better it is able to transfer any new heat the PC is creating. Same holds true on PC rooms hot air is rising and cold air is being pushed down..... So go GET ER DONE.

I think the only time I noticed something that OP debate is about, was about 9-10 years ago.
We rented an apartment, and I've decided to take a walk-in closet and make it into my mini-office.
It did not have windows or AC, but heating was there.
I ran my first quad-core Phenom rig with a moderate overclock (on an old M2N SLI Deluxe) and an HD2900XT. I also had a big-ass CNPS9900 LED with some additional fans inside the case, so my rig was not only hot, it was also loud and bright.
Overall the temperature never dropped below 35C in that room during gaming sessions.

The total area was somewhere in the ballpark of 6 sq. m.

Normal people with normal rigs should not worry about this problem.

 

[eidairaman1]

just run an AC unit.

 

[Solaris17]

the air temp should be ever so slightly higher.

No because you cant create more heat than is being created via the object.

The room temp would be the same.

I dont have time to draw something up maybe someone else will but lets put it like this.

everyone knows heat dissipation is measured in watts right? Lets just use that we wont go deep into thermal dynamics. We will keep it exclusive to PCs.

Lets say you have a CPU that is bleeding 200w.

Now dissipation is helped by coolers but not all the heat can be dissipated because then the CPU would be ambient right? Lets take a look.

You have a CPU dissipating 200W. With the computer running your room sits at 26C (78F).

Your cooler is capable of dissipating 150w of heat. Meaning your CPU is retaining 50W of heat.

Now we all know we dont live in space, so while the cooler cannot bleed 200W of heat the 50w of heat isnt staying with the CPU its just bleeding off the motherboard off the IHS etc etc.

now you buy a better cooler. This cooler can dissipate 180w of heat. Which means at the most your CPU is retaining 20w of heat and bleeding it off some other way.

Now since the CPU is retaining less heat the idle temp has now dropped. Which makes sense we went from 50 to 20w of retained heat.

However, 150 + 50 = 200w

Our new calculation is 180 + 20 = 200w

We changed how heat is dissipated but we are still dissipating the same 200w in total, the CPU did not generate any more or less heat. so our room stays at 26C (78F).

Didn't read anything but the title. The answer is simply, NO.

Edit: just read the thread... wow.

 

[AsRock]

Hell yeah, i put best god dam cooler on my GPU toeject as much heat as possible now i can sit here in my shorts in winter

Not really!.

 

[CAPSLOCKSTUCK]

Im just going to find a 6 year old and ask them.

 

[Vulcansheart]

So many different answers... each one flawed in some way lol

 

[Beastie]

Thermodynamics. Ain't life a bitch?

 

[Mussels]

if your current understanding produces infinite heat or infinite cooling, rethink things.

 

[Vulcansheart]

We can all agree that a PC in a closed room will increase the ambient temperature of that room.

We can all agree that without the A/C system in your home, the ambient temperature of that room will continue to rise while the PC is powered on.

We can all agree that without a cooler, the CPU cannot efficiently dissipate it's heat into the air surrounding it. It will simply burn up.

We can all agree that it is then the sole job of the CPU cooler to exchange heat - hot processor exchanges with cold ambient air.

Why then can we not agree on what happens to the ambient air in the room? To me, it's quite simple. The more efficient the cooler, the warmer the room becomes. It's a simple heat exchanger thermo-101 problem. If the cooler didn't matter, then why not run the CPU without one?

That said, I still voted "same" simply because a couple watts here or there will not make a noticeable difference for all intents and purposes of this vote lol

"The more efficient the cooler, the warmer the room becomes."

The more efficient the cooler, the quicker the room becomes warmer.

an example would be if your heatsink was at 100C when the PC was switched off - a 'terrible' cooler (because its off) - does that heat fail to get transferred? no, it just takes longer to reach the room. Still the same amount of heat, just gunna take a little longer to get out of the PC case.

at any point someone thinks trapping hot air in the case keeps the room colder, that will only work if the heat *never* leaves, which means your PC is going to overheat. throttle, and/or crash.

 

[Deleted member 24505]

Same wattage, same heat.

I agree 100% with 50% of your statement lol. The room will become warmer quicker. Since we aren't talking about saturating the room with heat to the point of equilibrium, then we've answered the OP's question. The more efficient the cooler, the quicker the room becomes warmer. Thus, at any given time interveral, the room is warmer with a better cooler than it would have been with a worse cooler.


edit
This is all assuming that the aftermarket cooler isn't a piece of crap that does a worse job than the factory unit lol
