Not a huge issue in and of itself. Nand memory actually prefers to run hot, it works better when it does. Operating Temps of 70C are normal, which is pretty darn hot to the touch.

Even though a water temperature of 110° F (43C) is 'relatively-safe', exposure can be painful; the human pain threshold is around 106-108° F (42C) ... A child can suffer a third-degree burn in 124°F (51C) water in less than three minutes. Children and adults can be burned this badly in two seconds or sooner in 149°F water .. A safer temperature for domestic hot water is below 50°C. This is because water at a lower temperature takes longer to cause injury. For example: At 60°C, it takes one second for hot water to cause third-degree burns.

Exactly. Which is why i pointed out it's hot to the touch, but it's not really an issue from an operational standpoint.  Many people assume that because it's that hot to the touch, something may be wrong or that it's going to die a quick death.  I was pointing out that this isn't an issue as operationally, NAND memory has no issue running at that temp, it's part and parcel with the fast speeds you're going to get.

Whether your fingers enjoy touching it after a long transfer is a totally different issue entirely. One might want to wait a bit under such scenarios
