Check price and buyA millimeter is the thickness most benches consume fastest, and this is that thickness in the largest sheet and the highest conductivity offered here. The 120 x 120 mm square of 15 W/mK GP-Ultimate holds enough material for a run of motherboards or a shelf of graphics cards without the packaging and reordering the same area in small sheets would involve.
Watch what leaves the bench over a few months and one or two thicknesses will dominate while the outliers sit untouched. Holding the everyday size in bulk and the rare ones as single sheets matches the money to the workload instead of spreading it evenly across sizes nobody reaches for.
Power-delivery heatsinks on two sides of a socket, a chipset plate and a pair of drive shields add up to a surprising amount of surface. From a square this size all of it comes off one piece, cut in one session, with the offcuts still large enough to be the next job.
A bulk sheet makes generosity easy, and generosity is the wrong instinct with interface material. Extra thickness holds the assembly apart and lengthens the path the heat has to cross. Cut to the measurement even when there is a whole square left, because the pad that helps is the one that fits.
A rotary cutter against a long steel rule beats a craft knife on a run this length, because one continuous pass leaves a truer edge than several overlapping ones. Whatever the tool, fit a fresh blade first: a dragged edge is the most common defect in material cut on a bench.
