The title pretty much sums it up. One of my old sticks died (1.65v), so I ordered new ones (1.5v). Timings are both the same, as are the speeds. Can all three be used together, or should I just sell the remaining old one? For reference, both will be linked below.
I'd sell, mixing the two will require one to run at a higher voltage (more heat or the other to run at a lower voltage (more strain = more heat), generally just not worth it, either way one could cause the other(s) to fail
