COD4 Multiplayer makes computer fans loud and hot.

When you play online games it will usually require more system resources to power. Your processor also handles the data that is being sent and received during your online session. Some code for online games have more overhead than others. I do not believe that it has anything to do with your machine, but more the software and network overhead that the multiplayer game requires. If you notice that both single and multiplayer run on seperate executables...

Single Player = C:\Program Files\Activision\Call of Duty 4 - Modern Warfare\iw3sp.exe
Multiplayer = C:\Program Files\Activision\Call of Duty 4 - Modern Warfare\iw3mp.exe

Hope this helped!
