For the cooling of a Gigabyte Eagle OC RTX 3060TI I have a water block available to use on the GPU (connected to a custom system) and I should dissipate the VRMs and the Memories with heat sinks and fans placed on it. I have some doubts about it: - 1. Regarding the VRMs, should only those related to the GPU be dissipated or also the others present on the card? (for example the VRMs of the vrams) (In fact, in addition to the 6 vrms next to the gpu on the left side, looking at the card from the front, there are two on the right side, possibly vrm of the vrams, and maybe one on the upper left side of the gpu) (Also, the thermal pads that allow stock heatsink contact are only present on GPU vrms, as well as most video cards) (if there are other components to cool besides vram and vrm, could you indicate them to me on the board?) - 2. Only the VRMs or even the CHOKEs (the cube-shaped chips marked R15 next to the VRMs) need to be cooled (some boards also have the thermal pad on these, but I don't know if it's for safety when placing the heatsink or it's because they really heat up and need to be cooled down) - 3. Which of these options is more efficient in terms of dissipation? A. small dissipators mounted directly on the chips (vrm and vram) glued with a thermoconductive double-sided adhesive) B. self-built aluminum plate, cut to size, to increase the dissipating surface, in contact with VRM, RAM, or both, using thermal paste (or a pad, for safety). The plate (or several plate if it will be used only for the VRM andr for the RAM) will be fixed with screws, using the holes in the video card. Heatsinks will be glued to the plate using thermoconductive double-sided tape. (is it worth having this greater dissipating surface and exploiting more heatsinks glued on top or does the mere fact of using pastes (or pads), double-sided tape lose the advantage? Furthermore, is it risky for any short circuits due to contact?) Thank you
I have done the undervolt (1950Mhz and 0.925v) and the temperatures have decreased by 2°-4°C on the GPU and on the hotspot, in benchmarks such as heaven, timespy and firestrike, while they have decreased by 10°C in cyberpunk 2077 benchmark. Better if I can improve the situation more, at no cost. So, I put a water block (not fullcover) on the GPU and heatsinks on the memories and mosfets and I placed two 80mm fans at low speed, one on the mosfets and one blowing on memoirs (all things I already had). The temperatures of the GPU and the hotspot have now decreased by about 20-30°C. I would just like to understand if heatsinks plus fans are enough to cool the mosfets and memories.
If you have good airflow in the case and near the card then VRM cooling isnt a must unless you really want to push the card really hard.
