I think it might be the CPU?
The CPU usually gets the warmest. Graphics cards may get quite hot also. The bit where the fans blow out will have hot/ warm air coming out, from the bits that get hot. If it is a desktop style computer, it usually is unnoticeable, but most people have laptops nowadays..

So its mainly the CPU and graphics card if anything?
UM everyone does the RAM got hot at all?!
Not a significant amount compared to a CPU. I would guess they get a little warm during normal usage.
I set up some arduino based temp probes. the air coming out of my PC is 101f (38.5c). The air coming out the top of my MONITOR is 115f (46.5c).
I have done some water cooling and some AC unit based phase change cooling in the past for raw CPU/GPU power through overclocking. Got 5ghz out of an E8600 with some but not all benchmarks passing. Would do 4.5ghz. That thing ate a lot of voltage, I did not check output from the case versus the monitor back then.
Currently on a different CPU though, for actual heat into the room, my monitor is beating my current 8 core i7 easily on temperature. Granted the volume of air moving with fans in the PC is far different than the convection based airflow out the top of my monitor, but omfg is this 2k 1440p screen hot. Those temp probes are physically touching the CPU heatsink and the monitor shell (in back above the stand mount). The monitor is physically much hotter than the CPU heatsink. Some food for thought if you are working on controlling the user environment versus increasing the machine's performance.
Deafinately the cpu, I had one get up to a couple hundred degrees without the heat sink one time.
Perhaps we should be answering: What part of the computer has to dissipate the most heat ? To which the answer is probably, as we seem to agree, the processor. Steve
Definitely the processor. Though some bits of the motherboard also get hot.
It depends, my CPU has a good cooler it's always sub 50o, the GPU gets hot, the HDD gets hot, power is not necessarily the same as temperature (I'm not sure which is being asked here though). L
Strange question. CPU / GPU can run hot depending upon how they are cooled and how hard they are working. A dektop PSU will have hot bits in it, and some of them may run hotter than your CPU / GPU. Why? L
The graphics card can sometimes get the hottest, up to 70 or 80'c at load because it only has a relatively small fan compared to the CPU. The CPU usually dissipates the most heat but because it has a bigger fan, it's temperature is usually lower than the graphics card. If your computer is overheating, blow all the dust out the heatsink and that should sort it out, or, if you are confident, take the heatsinks off the CPU and even GPU and replace the thermal compound with a silver based one.
