MCS 7835's Running Hot

I am seeing elevated call manager temps reported by ITEM in the 35-40 (C) range. Alarms are set to 30 by default, and 35 is the published maximum. The IPT rack has 8 MCS7835's stacked up with no spaces in-between. We've decreased datacenter environment temp, removed rack panels and put a fan blowing directly on the rack.

In past and similar deployments, temp has also been an ongoing concern.

Is there a portion of the design guide that specifies rack density for 7835's or maximum abmient temp for the evironment? Also, does anyone know of unpublished operating maximums?

max temp is 101.7° F (38.7° C)

as stated here:

I don't see where a rack density is specified though.
