The fan reading is correct, we use the R290X without the case and without the fan. The case is 1U and there is a shroud in place to keep the airflow on the heatsink and we start the 4x dedicated loud case blowers when we use the card - keeps it at around 72-75 Celsius easily. I love this card, the heatsink blades are aligned to the card length (and not at a 90 degrees angle), which allows for the use of case fans.
Anyway, I have used the same card in the same setup (no fan) in both machines, and the performance diff is still there. I have checked with GPU case + fan and without them, no change in the measurements. So unfortunately this is not the reason ... could be something related to the chipset? PCI GEN3? Strange ...
