There is a very cheap Intel X540-T2 10 Gigabit electrical port network card, HP server disassembly, a single card, then sold for $ 15, but can not be used directly for desktop computers, because the PCIE slot location is not correct, and then someone through the adapter and then $ 25 to sell.X540-T2

I bought a X540-T2 more than a year ago, said the DELL server disassembly, 60 U.S. dollars a piece, with cooling fan, the noise is not low, can not stand. See now X540-T2 are no fan of a large cooling. So search a little, there is really a single sale X540-T2 heatsink.

Let’s start with the $25 X540-T2 NIC. There is a drawback, because the adapter, only with a full height baffle, ITX small cases are not suitable. Back side.

X520 is MAC and PHY chip separate, X540 MAT and PHY are placed on a chip, power consumption and heat generation are significantly lower than the X520, X550 lower, so see now X540 and X550 do not need to use the fan.
