Is it possible to set up a pumpless watercooling system for a cpu, gpu and northbridge on a single radiator?
Also does such a system absolutely need TEC's to work or do they just improve performance?
I was thinking of doing a piecemeal watercooling build, and the pump is the most expensive component, so if i could make do with a thermosyphon it may be a cheap way to start.
No

TEC is neccesary.. CPU will overheat before enough heat is generated to start a good flow of heat from the WB to the rad and back.
Im far from an expert on this subject, but from what I have seen of the thermosphyns, only one waterblock at a time will really work. Probably a mixture of flow restriction, tubing issues, and heat buildup.
