Hot!

my room this summer has been getting ridiculously hot with my computer running I was thinking about getting a water cooler as im using the  stock cooler. Will using water cooling eep my room temperture lower? and a suggestion for a water coller would be nice.. im using an amd phenom 2 965 cpu and its in a thermaltake commander ms-i. thanks

water coooling would stop your room from getting hotter since the pc wouldnt be kicking out as much heat on what cooler you should get i dont have a clue

Its a fact that your hot air exhaust will be lowered, but only for the CPU, if your GPU(s?) or other hardware is still exhausting too much heat, I'm afraid it wouldnt make much diffrence.

Wouldn't a watercooler just make your room hottter by moving more heat from your cpu into the air of your room?

Have never messed with watercoolers, but I would assume that the radiator would slow down the heat transfer? Doesn't water in general take longer to change temperature? 

This is how I see it. Lets consider the heatsink (air/water), cpu, and room are all in one system. All three are trying to get to thermal equilibrium (all equal temp). The water cooler does this more efficiently than air (which is the reason for water coolers, to get the temp of cpu closer to room temp). So with water cooler, all three are closer in temp than with an air cooler.

You guys don't know much about thermodynamics. Getting a more efficient cooling solution is only going to increase the heat transfer to the surrounding air within a room making it "feel" "hotter" than it was before. Unless you have a secondary way to remove heat from the air within the room, ie an air conditioning system, you aren't going to get any heat out of the room the system is in. The air surrounding the system will absorb heat from the system till both the air within the room and the system are the same temperature.

Yes batojiri, you are right. Energy cannot be created or destroyed. In long term, the room will match up to the cpu's heat dissipation.

In short term, there is a situation where the heat capacity isnt reached yet. As water is much more dense than air, it will take a much longer time to raise the ambient temperature to the cpu's heat level. This is even prolonged when you take breaks of cpu stressful situations.

Took me a while to realise this, after i read your correct answer, i couldnt figure out why my exhaust wasnt as hot as i remember with my air cooling. The water takes a much longer time to heat up, and serves as a heat-delaying barrier.
