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

[TheBurn]

There you go, hope that makes sense to you. (click expand, i highlighted my bits in blue)

Mmm Pretty blue highlights... but no.

A heatsink is designed to absorb and hold heat and then dissipate, that is its design without a fan(passive means), from there its dissipation or release of heat otherwise from passive means from the heatsink is via other means such as a fan controller or as we are so familiar with a means of water cooling heat radiation release(radiator)..



But back to the orig poll. The answer is yes

 

[jagjitnatt]

An aftermarket cooler would dump heat from the CPU to the room faster, so it would raise the temperature of the room faster(not more, just faster)
A bad cooler would take more time to dump the same amount of heat, and since your room would be losing heat(assuming its cold outside) at a certain rate, the overall temp of the room would rise slower.

If I was to run a load for 1 min, the aftermarket cooler would heat the room more(at the time I switch off the load), because the stock cooler(and the CPU) is still holding some heat and is yet to dump it into the room. But if I was to run this experiment over long period of time, both the heatsinks would reach their peak dissipation rate, and the difference would be negligible. But once the CPU is at idle, the aftermarket heatsink would stop dissipating heat, but the stock heat sink would still be dumping the heat it is holding.

So even though the amount of heat dumped in the room is same, the peak temp in the room would be higher with the aftermarket cooler.

There are a LOT more factors that in play here like the heat dissipation rate of the room will increase as the delta of temp between room and outside increases and the rate of dissipation of heatsink varies based on the temperature of the air around it etc

Errrr....

So we aren't testing within a vacuum, and the fact of you being in the room increasing the ambient temp; its a measurement of the temp overall in the household room or gamers room. with you and the gaming computer powered on within it. There is some ambient air temp change in the room affected by a window, or door where air escapes or enters the environment.

So a larger CPU heatsink will hold more heat and dissipates less heat then its lower mass counterpart This is the essential design of top quality heatsinks.
A WC heatsink transfers heat from the block, but via tubing and water, exiting via the radiator essentially in its design.
The normal user can measure the air temperature dissipated from the fan exhausts of the pc case. And there would be a significant difference thats measurable using a large heatsink, versus smaller passive/or active heatsink, versus WC system. And this effects ambient air temperature in the room; how would it not ?

So if the aftermarket(larger and better designed) cooler can contain more heatmass and dissipate less heat, then the case temp and room ambient temp changes less over time.

Where is the wrong?

Just all of the above comment....

The larger cooler dissipates MORE heat(wattage)... Sure, it 'holds' more before its saturated, but after it reaches an equilibrium, its the same. I mean, if what you were saying was true, why would larger coolers keep temps lower if it isn 't moving more heat than another cooler??? The point is to GET RID OF the heat!!!!

Again, 100W at 50C is the same as 100W at 70C. Its still 100W of energy trying to 'warm' the air it touches...

 

[sneekypeet]

Testing a shit ton of coolers per year, I can say, not matter what the cooler is, my room will eventually get to the same temperature if left to run long enough.
I have thought about doing a video or posting images, but I feel the video would have to be hours long, and images would be claimed as fakes to those who do not believe what most of us are saying!

No it's not designed to hold heat, it's designed solely to dissipate it away from the CPU.... what kind of spongey heatsinks do you use?

 

[rruff]

A heatsink is designed to absorb and hold heat and then dissipate.

The heatsink is designed to dissipate, not hold. The size is strictly due to dissipation demands only (exchange heat between the CPU and the air). None of them have enough heat capacity relative to the amount of energy being generated to make a difference.

If your after market cooler has 2x the heat capacity and also runs at 1/2 the dT then the amount of energy absorbed would actually be the same (rather than some infinitesimal difference).

The laws of Thermodynamics.

Honestly, this is still going?

It's amazing how many people think that Science is an opinion!

107 to 15. Game over. You lose.

I'll have to climb onto the roof over my room and mount a cooler there to see if it does or not.

If the cooler is removing heat, it naturally goes out of the system and into the room, plain and simple. If the cooler is removing more heat then you may see a difference BUT in some cases a room may or may not be better insulated, larger or smaller, in a warmer or cooler climate based on where the home itself is.... Lots of variables can affect things but I can say from my own experience my room did get a little warmer after I upgraded the cooler from a stock one.

Urgh, the amount of heat a large cooler and stock cooler is removing is the same.

There will be slight differences due to CPUs at higher temp having a lower resistance, but the effect would not be noticeable.

There are no other variables that would change the amount of 'heat' put into the room.

There are literally 8-pages explaining the Science and it's explained in layman's terms.

I'm just so disappointed that I found this excellent discussion so late!

Being quite a fan of experiments, I have to say: I have nothing against testing the law of conservation of energy, because - well - why not? There clearly are worse ways to spend time.
That said, I'm pretty amazed some people decided that it doesn't work.

I think we should have more topics like this one!

A thread discussing the merits of a perpetual motion machine will pop up next!

reminds me of the days i used to have two reference 6970s that ran at 89'c load.... It was like the Caribbean here.

There must be something wrong with me...........i keep clicking on this thread.......

Maybe you need room heaters to save on the electricity bill

 

[CAPSLOCKSTUCK]

Its 24C in my sitting room which equates to

1. X 5670 and HD 7970 which are both ticking over
2. A roaring fire stoked with Welsh anthracite.

need to see "logs "
Oh you cannot provide logs "you burned them last week"

 

[CAPSLOCKSTUCK]

"you burned them last week"

i did actually. My wife chatted up some local builders and they dropped off enough timber to last us all last week.

back on topic. If our fire goes out overnight the room is still warm in the morning, this is because all the furniture and fittings act as a heat sink and slowly release heat until everything returns to the ambient temperature.

Consequently i have changed my vote to "other"

 

[infrared]

We're all in a simulation so have no idea if the physics we experience is real

Free your mind! haha

 

[Mr.Scott]

I'm shocked and appalled at some of you guys that I once respected.

X Wattage = X Wattage
Period.
Coolers type/size does not change that.

I can't believe there are actually people logging in for the first time to argue this.

People tend to have misconstrued ideas about some things based off entirely wrong ideas that fit other big picture items.

Dihydrogen Monoxide anyone? Infused with your flavors of choice?

I prefer the classic Lemon water, thank you.
