RAM/VRM Heatsinks
Memory chips and VRM stages sit outside the die, so a CPU or GPU block does nothing for them. On a card you are stripping for a water block, or a board being pushed hard, small heatsinks and thermal pads are what keep those parts in range.
Copper pulls heat faster and is the usual choice for GPU memory. Alphacool copper RAM heatsinks come in 6.5 x 6.5mm, 10 x 10mm and 14 x 14mm, in 10 packs. ModMyMods cold forged copper heatsinks cover the same job in a 10mm x 10mm x 7mm 10 pack.
Aluminum is lighter and cheaper for larger surfaces. Alphacool black GPU heatsinks come in 7 x 7 x 15mm and 15 x 15 x 15mm 10 packs, and the ES passive aluminum coolers at 100 x 120 x 22mm and 200 x 120 x 25mm are sized for server and rack builds rather than a single chip.
For system memory: the Barrowch DDR5 single dimm heatsink in black, and a Barrowch RAM active air cooler if the sticks sit under a blocked airflow path. Chipset sinks at 10 x 10 x 10mm and a 14 x 14 x 10mm Aavid Thermalloy premium sink round it out.
Heatsinks need thermal pads to actually transfer anything. Pads are in thermal pads and compounds.
