FORE / Marconi ESX 2400 and ESX 4800
These heat-sinks or IC-coolers are glued on every RAMbus memory module on the switchboards and doughter boards. And there is one RAM chip for every port and shwithing channel.
herausgerissen-115b.jpg (17111 Byte) As you can see, accepting bad handling of these boards, the cooler will be left or damaged and then the chip will become very hot die shortly.

Currently we are looking for a source for these coolers as well as for the glue.
