Yep. Sager NP7330 GFX 765m doesn't have it's own INDIVIDUAL fan, but it shares a connection with the CPU HS/fan via heatpipe.

My old MSI GT725 w/4850 mobility had a shared setup like the 7330.
Pretty much any dGPU is going to have some kind of fan setup and NOT just rely on a heatsink. Mobile dGPUs run a bit warmer than their desktop counterparts, e.g. 780m is specwise, very similar to the GTX 670(which I have), not sure what the 765m corresponds to from the desktop... 660 or 650 maybe?(768 shaders) And the old 4850 was an oddity, same specs as the 4850 desktop variant(shader count) but w/lower core/mem clocks(the ONLY time that I can recall that current mobile GPUs had identical specs other than core/mem clocks as analogous desktop parts, didn't last long though, next iteration was back to the not quite matching similarly "named" desktop part).
