Unless the installed cards are "Blower" style, you will have airflow issues with the top card. Blower cards will always cool better in our Precision Workstations.
You would do better finding a used GTX 1070 blower card, and putting that into the upper slot. On a side note the GTX 1070 is a better card for gaming.
Thank you for your reply. So if I understand you correctly: Precision T5500 MB CAN run 2 GPUs in SLI mode, but only if the two GPUs are blower-style (hamster-wheel) vented.. right?
Inasmuch as your GTX1070 suggestion, I think nVidia prescribes that any 2 GPUs mounted in SLI configuration must be identical....which scraps my idea of getting a 2nd GTX1660super card because I don't think they come in blower-style. As mentioned before, my objective with these is mining, as hobby. So gaming isn't really on my radar. But as far as I know, maybe SLI setup isn't even necessary for mining with two cards? I'm spitballing over here.
Please let me know if you think the above makes sense.. or might you kindly suggest another possible solution?
Honestly, SLI is a mixed bag. Some games get a huge fps boost, while others have performance issues (frame pacing for example), and a large number of games do not even support it.... Have you checked to see if your GTX 1660 Super even has an SLI port? I am not seeing any models that include them. With the Ampere architecture Nvidia moved away from SLI and introduced NVLink on the high end cards (RTX 2070 Super and higher).
I'm curious as to what you settled on for your final configuration. I rebuild HP z600s and Dell T5500s for gaming purposes and have long wanted to try SLI in both computers with a GTX 1660, whichever flavor of that card fits into the cases. Both the z600 and T5500 have dual GPU slots that operate at full PCIx16 (though they are gen 2.0), whereas the vast majority of gaming motherboards scale down the speed of the PCIx slots when more than one card is added (8x, 8x for two cards and 4x, 4x, 4x when three cards).

So, please post your results!
