[Dsg-rich] rich air flow

[Marco Mirazita]

Hi all,
I noticed that in the last couple of days the air flow on the two lines 
feeding the RICH went down by approximately 10%.
At the same time, the FPGA temperatures slightly increased.
Then at some time tonight the air flow started to go up again.
While no real problem has been encountered (tile 128 is the hottest one 
and never went above 68 deg) it would be interesting to understand why 
this happened.
See the attached strip charts.
Best regards,
Marco
