I've noticed that on 98% of Custom GPU board, unless you're buying and assembling a third-party cooling system. That the VRAM and VRM circuitry is cooled by the main fan slightly above, without any additional heatsinks.
(For example, the GTX 750ti tomshardware tore down)
Now, I have two GTX 970's arriving today. I plan to overclock the living hell out of them. Would there be any benefit if I were to slide in some low-profile VRAM heatsinks such as http:// ?
I assume the gains if any would be minimal. I would also suspect the outcome to simply be, if anything a miniscule boost in life longevity due to being a few degree's shaved off.
But would that allow me at all to overclock a bit further, with a bit less thermal stress on the VRAM and VRM circuitry? I mean these little copper sinks you can pick up stacks of them for under $10. Would it be worth looking into?
