Yeah, good advice to get rid of the fan filter material, Paul. With the HP 
8568B & 8566B, Signal Analysis Division (SAD) weighed the pros and cons of 
keeping the instrument clean vs. risk of over-heating if the fan filters 
were not kept clean. They decided in favor of reduced risk of heat damage, 
and eliminated the fan filters, from then on shipping the boxes without the 
fan filters.

Its soft and sticky. At a min get rid of it.
My environments clean so I leave them out.
