I'm as close as you're likely to get and frankly, no, this is high school level science. It's really sad.
Its not that bad actually. It seems most people forget everything they learn in high school, and even though this is a long thread, 90% of the audience chose the right answer. There were just a few misconceptions here and there...

Yes, I suppose that is correct.

You're right, it is sad. If all CPU coolers were created equal, why would there even be a market?

May I ask your qualifications to make that first claim?

Lets say you have a giant cooler and your rooms window open with your case dissipating/directing all heat outside the fucking window.

Yes, your room will stay cooler.

Total heat won't change (excluding delta in fan wattage), but it's not so simple in the real world. A very high cfm system may tend towards evenly heating a room. A very low cfm system could cause very hot air to rise to the ceiling, which may actually keep the room cooler down where you are, if there's little circulation, and the ceiling insulation is poor, effectively heatsinking the concentrated heat at the top of the room. As soon as you turn on a ceiling fan, the effect would be lost, and the heat would be evenly distributed again. However undoubtedly the two HSF setups in question are similar. Ah, post #70 has a nice graph, showing the "better cooler" is causing room temp to rise more rapidly, as heat is more evenly distributed in the room initially. Though I feel that the post's reasoning implies the wrong thing.

CPU coolers are for keeping the CPU cool. Not to keep your room cool.

I'm not the guy you were asking but I have an mechanical engineering degree and specialty in heat transfer.

This is the only thing of interest regarding this question. If the CPU is dissipating the same power, then that heat is going into the room one way or another.

But... if the CPU produces less heat if it's cooler, that may result in slightly lower room temperatures, provided that the cooler itself doesn't generate so much heat that it negates the savings. Power draw is a good measure. If your cooling system draws 20W more than your original, and the CPU draws 20W less, then nothing changed as far as the amount of heat dumped into the room.
It think its safe to assume it wont make a difference anyway. 20 W is more than I anticipated (for both increase in power consumption and pump power), but even if its +/- 20 W, still wont have a noticeable impact on the room.

I'll give you a hint: the room temperature is raising at a varying rate. It doesn't instantaneously warm up the moment the PC is powered on. The rate that the room warms is directly effected by the efficiency of the CPU cooler.
Who the eff cares what the final room temperature is going to be? It could take 24, 48 or 1000 hours to reach it's maximum temperature. What I am arguing, and have been arguing since my first reply, is that at ANY given time interval between 0 and X hours, the room will be warmer with the aftermarket cooler.

What does "efficiency of the CPU cooler" mean? Efficiency normally implies that you get more output for the input. In this case that would mean the aftermarket cooler requires less watts to cool the CPU, which would put less watts into the room.

If you want to look at the effect of thermal capacity, here is a chart: http://www2.ucdsb.on.ca/tiss/stretton/database/specific_heat_capacity_table.html
1 watt is 1 J/s. Aluminum is .9 J/g-K. dt=M*dT*Cp/P. For example if you had your processor attached to an insulated 200g hunk of aluminum, and your processor ran at 100W, a 50C temperature rise would take 200*50*.9/100 = 90 seconds. I wouldn't count on your heat sink making an appreciable difference.

I am disappointed in humanity at this point. This is high school science stuff people...
The fact that almost 10% of people of a technology forum don't understand basic physics does not bode well for the future of our species.
I feel quite positive about the results of this poll.

I get a warm glow just from being a participant in a forum where 9/10ths of voters understand basic thermodynamics.

Your first question is NOT the same as the question asked in the poll. The question in the poll is more of a, which is heavier a ton of feathers, or a ton of bricks?

The first is a question about the total room, NOT the CPU. If a ROOM is 70F and a CPU cooler can manage to keep the CPU at 100F under full load 125W (for example), we would say the cooler was able to remove 125W of heat at 30 T delta. If you got an after market cooler and it kept the CPU at 90F, 125W under full loaded all else being equal, the after market cooler would be better, it would have a 20 T Delta.

The same 125W is being dissipated irregardless of a better cooler. Lets agree on that.
The room will remain at 70F AVERAGE irregardless of what cooler is used as 125W is being dissipated. Lets agree on that.
The CPU temperature will be the ONLY change, but heat flow (flux) will remain the same.

When controlling for all other variables, the same total heat will be entering the room, the only difference is the Thermal Flux Delta (thermal conductive/capacitance) of how well the cooler can move heat from point A to point B.

That is why and how we use better coolers, their TDelta is better, and that is why people review coolers in the same environment.

Lets do a thought experiment, if you have bottle of champagne to cool ( for V day) and you wanted to cool it, whats the most efficient way cause bae is showing up wearing a garter, thigh highs, and a trench coat in 15 minutes and we forgot the champagne in the trunk and its 90F

We can cool it with water that has a Tdelta of 40F lower than the champagne.
We have air in the fridge that has a Tdelta of 70F lower than the champagne.
We have ice that has a Tdelta of 90F lower than the champagne.
We have salt.

The answer is to add salt to the ice, and a little water to cover as much of the bottle as possible.

Does the salt make ice colder? Nope. It increases the thermal flux of the water, allowing the water to remain liquid water even in below freezing conditions, which increases the chance of the champagne being ice cold and bubbly. Without making this a full physics lesson, you will always have the same amount out as you put in when dealing with heat, the only thing we can change is the amount of transfer to make everything closer to equal.

Next time we get our fire extinguishers refilled at work I will nab one and see how cold it actually gets with the CO2, it may be warmer than you think due to the fire suppression chemicals.

Rest Assured it gets Damm Cold.
Cold enough to give you FROST BURNS, if you fail to read the Safety warnings about holding the CO2 extinguisher nozzle or Horn while using one,
and it also blasts cold enough to cold shatter Steel padlock shanks with a hammer

No. The CPU produces exactly the same amount of heat. That heat is just over a larger surface area CAUSING a lower temperature.

Temperature does not cause heat change. Heat causes temperature.change. Heat and temperature are 2 different things.

You're right, it is sad. If all CPU coolers were created equal, why would there even be a market?

May I ask your qualifications to make that first claim?

They are no created equal. Some can dissipate larger amounts of heat resulting in lower temperatures on the CPU. But the CPU is the sole source of said heat. When that heat is dumped into another system (the room) it will cause a different temperature change to that system. If the amount of heat being dumped into that system is the same, the temperature change will be the same.

The zero's law might help some to understand better. I don;t have time to explain now, but basically, the CPU in both cases, is trying to reach thermal equilibrium with the air in the room.

I ran my own bitcoin farm and helped with a large scale op, hot/cold aisle arrangement.

I was mistaken though, more qualified people are here. :)

A couple of people commented that the CPU will draw less power doing the same task if it's cooler (ie it will be more efficient). I figure they measured it?
