I am looking at doing a project that will be very space constrained, so heat dissipation will be a major concern. I plan on using a Pentium G4560 or G4600 (really can't afford the "i" processors right now). I do plan on trying out some underclocking/undervolting to keep heat down, but wondered if delidding and using a better TIM would provide enough benefit in temperature reduction on these processors to be worth it. What do you guys think?
