Question 1

does it come with a cooler?

Accepted Answer

No, the 5800X3D does not include a cooler, it is the CPU only.

Question 2

Why does it say none desktop? Is this for a laptop or server? Please clarify before I buy it for my desktop PC

Accepted Answer

That portion of the product title refers to the onboard graphics of the CPU, of which there is None.

Question 3

Is thermal paste included? I plan on re-using my existing cooler.

Accepted Answer

No, there is no included thermal paste.

Question 4

Can i cool this chip well with a 120mm liquid rad?

Accepted Answer

That depends. Yes, I would recommend that the cooler is on the intake instead of the exhaust of the case. And, also not overclocking.  If either of those is the case, then I would recommend a 240.

Question 5

Would I be able to run this with a RX580 with a Power supply of 600W?

Accepted Answer

You should be able to if you are already running an AMD CPU, since the power requirements have not changed for the Ryzen series.  You may not be able to do any overclocking unless the current power supply has the additional 4 pin power for the CPU.

Question 6

how is overclocking on the ryzen 7 5800x3d's are cocerned?  like 4.0 GHZ

Accepted Answer

Overclocking is disabled on this cpu. The reason why AMD chose not to allow overclocking on the Ryzen 7 5800X3D is due to voltages and thermals. As Hallock explained, the reason behind this is that the processor, with its gargantuan cache, can only reach up to 1.35V versus the maximum 1.6V that other Zen 3 chips can reach. As the Ryzen 7 5800X3D is already running at its maximum voltage of 1.35V, overvolting it could cause damage to the chip, so AMD chose to disable it. Although a few people have found work arounds to overclock this cpu it’s probably best to trust AMD and believe that overclocking this particular chip is still a risky business.
