I've had really good luck with a very large hole underneath the cabinet and
a several hundred CFM fan at the top. Telehouse has good underfloor
pressure so the larger the hole the better for the cabinet. I haven't had
good luck putting vented tiles behind - most of our equipment vents front
to rear inside the cabinets. My routers are very happy with the large
holes though:
card inlet hotpoint exhaust
RSP(2) 18C/64F 23C/73F 21C/69F
Although after seeing the rats nest of wires in some of the cabinets I've
seen over the years it's no wonder there are hotspots - nowhere for the air
to go. ;)
