Ok so I was having a debate with my brother today and we couldn't agree on the answer so I thought well why not bring it to the masses and see what everyone on here thinks.

The question/debate is.....Would the temperature of a room (his bedroom) be higher, lower or the same when using a bigger after market cooler compared to the stock intel cooler on his current CPU. He thinks the temp would be hotter in his room with using a bigger after market heatsink (dissipating heat would be the same and more of it), I think it would be slightly cooler because of the total mass/size of the cooler would lower the temp before it was blown (dissipated) into the room, but maybe Im wrong.

What do you all think? and we are looking for overall temperature of the room when using different cooling compared to stock. Will it raise the temp, lower the temp (or have a lower max temp) or be the exact same temp.

Cast your votes and thoughts.

It will stay the same. The amount of heat generated by the processor will be the same. So the heat entering the room due to the computer will be the same, so the temperature in the room will be the same. This is basic thermodynamics. The key is how much heat is generated, not the method of how it is being dissipated into the surrounding air.

*Using a smaller cooler might trap a small amount of heat in the processor(why it would get hotter), but the amount of heat trapped in the CPU would not make any measurable difference in the room temperature. The amount of mass of the CPU compared to the volume of air in the room means the amount of heat needed to be trapped to double the CPU's temperature would not even come close to make a measurable difference in air temperature in a room. Even with the most precise measuring instruments available, you would not be able to measure the temperature difference in the room.

Now to clarify, we are basically only talking about idle temps and that we would be talking about a base starting room temp of lets say 10c and warming up to said possible temp depending on cooling used.

We all know a stock intel cooler on a intel CPU will run hotter then an after market cooler, eg at idle on a 2550K be 40c, this then transfers that 40c into the room. Now an after market cooler would bring down that over all temp of the CPU to lets say 30c, there fore transferring that 30c into the room, no?

So far its interesting to see what answers are coming up :) Links are welcome btw

The ambient temperature difference between the two will be negligible, so I voted "same". However, technically since the aftermarket unit *should be a more effective heat exchanger, the room should be warmer and the chip cooler.

The same overall. Thermodynamics don't change
You transfer more heat from the inside of the CPU to the room in a faster pace but that won't change the total heat output to the room

The heat "inside" the CPU also contributes to heat the room :)

I think the question implies whether or not the air temperature in the room would be higher or lower... since the heat would be more evenly distributed and more quickly dissipated, the air temp should be ever so slightly higher.

The overall heat would be the same but the air should be hotter and the chip should be cooler.

The air temperature of the room will sooner or later redistribute via convection, with or without an aftermarket cooler.
The heat inside a CPU will also dissipate to the air via convection and radiation but slower without the help of a fan, then a CPU produces more heat than dissipated and it overheats..
When you turn off a computer, the fan stops and the CPU cools down,

the CPU is still going to produce the same amount of heat. You can go from stock cooler to top end water, it will be the same. The chip will be cooler... because the cooling solution is cooling it much better than the stock cooler, but the same heat is still there, just not trapped in the chip.

the same amount of heat is produced and moved, all you're changing is how fast its relocated from the CPU to the air/exhausted into the room.

A PC in a room will raise the ambient temp a bit, nothing noticeable but there is a difference, switching to a bigger cooler though won't affect that temperature.

Yes your moving the heat but your also reducing the over all temp of the CPU as well as you move the heat otherwise having after market coolers would be completely pointless.

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.

Yes your moving the heat but your also reducing the over all temp of the CPU as well as you move the heat otherwise having after market coolers would be completely pointless.

The temp is reduced by removing the heat from the CPU itself. Aftermarket coolers are designed with a TDP limit. This means they can remove up to a certain amount of heat. An insufficient cooler will not extract the heat fast enough and the CPU gets hotter. Any heat extracted from a CPU must be vented into the space around it. A water loop will effectively reduce room temp as the storage of heat in the radiators will 'slow' the release into the air. Ultimately though, when the system is off, that heat must still escape through the loop and into the air so the 'dump' of heat takes longer, therefore resulting in a lower peak temp but longer raised temp (albeit by practically immeasurable amounts).

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.

The better a cooler cools, the hotter the extracted air. The purpose of any cooler is to remove the heat generated by the CPU from the system. The heat generated is a physical component of work done by the chip. That work, in a given CPU, will create 'x' amount of heat, which will be dispersed by whichever system is installed.

you are *only* moving the heat. it is 100% heat transfer and nothing else.
if you remove water from a bucket to a second bucket, you dont gain more water.


people get confused because they think in F/C, when thats now how it works.
'If CPU is at 50C and exhaust air is at 50C, my room must be at 50C' - clearly doesnt work that way, as you spread the same amount of heat into a larger area (heatsink, room air etc) the heat does not vanish or reduce it merely gets spread out

Lets go with **made up numbers** in BTU's

lets say with 100 BTU's made a CPU that ran at 100C, passively. Throw a fan on and the heat gets moved away into the air faster - was more BTU's of heat produced? No, the CPU temp dropped as its cooling increased, but the same total amount of heat was generated.

The literal only situation in which better cooling produces more heat, is if a system thermal throttles, because then the heat production reduces - so a properly cooled system produces more heat.

If one bucket is 10C hotter than the other, then the air around it will also be hotter, from radiated heat.

correct - you relocated the heat. you just discovered water cooling.

Processor uses all electricity to produce heat, so the actual temperature does not make any difference in heat production.
However Semiconductors have lover resistance the hotter they get, voltage is constant, then heat=voltage squared/resistance.
For example my 5970 dropped power draw by almost 20watt going from 90c to 40c under water. But this is negated by heat generated by water pump and ect.
In the end every PC is fancy electric heater.

Benchmark Scores Turns on on the first try! Usually.
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.
That is an ideal case, because most of the PC cases are not that isolated the heat will still somewhat spread in the room (which in this case we view as a closed system). Adding a bigger/better cooler changes the time parameter, so the room temp will still raise to a certain value, only the time to do so will be shorter (with a better cooler). That heat is still contained within a given system, how fast its current circulates is a different question.

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

Only if it exhausts outside.

Well with my current rig, mostly cool air comes out at the back, that was different with my old socket 775 system back in the days though, this one exhausted warm air.
