Look guys, we can go on forever like this.

Bigben2k: I'm NOT saying it's just convection at work here. It is about warming water expanding and displacing cooler water from the rad; this pours into the reservoir. Because the reservoir is above the waterblock in the circuit, the law of communicating vessels dictates that water coming out of the res outlet will gravitate down to the pump and then push up again toward the waterblock, as water in the tube and res try to level out. This pushes the expanding warming water in the block further upwards into the rad, and so on...

Want to test whether I'm right or not? Just move that res to the lowest point in the circuit (say, at pump level). Watch that temperature climb.

P.S. before we get on that bandwagon: I'm NOT saying it is just the law of communicating vessels at work here either; it is a combination of both.
