The case cooling and rack cooling is fine, one of our old racks has glass doors and the other is perforated. We run the servers in the second one ofcourse now.
The cases are made of colled-rolled-steel, 2u ofcourse. The intel p4 3.0 ghz's 1mb s478 works fine.. but for nforce we have a couple of 775's.. those are having problems all over the place... some software most hardware.
We are placing old s478's with coolermaster coolers tomorrow or the day after to see if things are getting better then.
The cooling itself is awsome, the motherboards is below a temperature of 18c. The cpus however hit the 85, 90 easiliy, and yes they are attached good and stable. The racks themself are good too we got airco coming out of the floor in the rack blowing like a storm. All racks are placed back to back and front to front. So it gets cool air from the front and the air on the back gets pulled upward due to the airco. We got extra deep 19" racks especially for this and for the wiring.
Anyways we'll see tomorrow.

whoKnows has right
the new P4 520J(2.8,) 530J(3.0) 540J(3.2) 550J(3.4) 560J(3.6) 570J(3.8,)
its like 90 watt and more but the a temperature below 50 idle
its like 12 to 25 degree less(idle) with virus DDOS protection
the dissipation seem to be like the stepping P4C
you guys ever try Zalman CNPS7000B-Cu or if you have lot of space 120mm cpu fan CNPS7700-Cu
thermalright and cooler master and scythe too are good product
i said stable with the celcius not in software(AMD Opteron)
P4E = high temp.....
p4C and J = good choice(J load is little higher)
people should reccomand which fan is better and a link(review of it to show the result)
here the first www.google.com to traduct it
french to english

Wow, somethings must be wrong with the cpus. Intel states that the air that is flowing to the cpu fans can reach a temp up to 38c (so 18 should be perfect). In your case the difference is really extreme - 18c to 90c. Did you get replacements, and did they heat up the same way?
I am curious, wich chipset are the boards using 915, 925 or Serverworks? Also, only the p4 with up to 3,4 Ghz (stepping e0, socket 775) have the new power managment, the 3,8ghz heats up like a power plant.
There is an interesting article on toms about the heat problems of the p4 560:

he need P4C(i saw that the p4J is better than E but at full load dont make a good change then take a p4C because its less temperature like around 65 full load intel stop produce them) or AMD processor (opteron 100 series and bi-cpu 200 series if they like) or a simple AMD64
anyway they or enough old to make their decision we suggest and only that
we just need to give review of product to make them take something or something that will be good.
