well it's obvious that in a colder room a CPU would run cooler, but that is not what i'm asking.

omit variables like case air flow etc in this.

so 2 identical computers, both running a benchmark, both producing the exact same amount of heat, and both have the fans running on the CPU at the same RPM, the only difference is that 1 is in a room that is 0C/32F in temperature and the other is in a room that is 30C/86F in temperature.

if both of these machines are running, with the only difference is the temperature, when you remove the CPU temp from the room temp and get the delta temperature eg:

(this is just an example, no scientific/acquired results it's just made up) 0c room CPU running at 20C -0C = 20C

30C room CPU running at 50C -30C = 20C

would the temperatures be the same at the end, or does the ambient room temperature have an effect on how well the CPU can loose watts of heat??

It would have a small amount of effect being hotter in the room but not much.

Read up on thermal dynamics and thermal conduction.

Only if the room is hotter than the CPU in which case you'll probably be dead anyway so it won't really matter!
