Fan EMI?

Has anyone measured the EMI from the recommended fans or any other fans?

I’m considering active internal cooling and passive external cooling using an RF tight enclosure. Heatsinks on the chips, a silicone pad between the bottom of the board and the case with an internal fan and internal and external heatsinks on the enclosure.

I tested my internal and external fan solution with terminated modified RX1_W input,
No strange spikes or wide EMI spotted.
Only W10 os notebook when glidepoint is used, make some RFI trouble on HF…
