This is a replacement for Fujitsu server part V26989-b886-v20. It is a CPU shroud around the cooler that also holds the FAN. I made it for 80mm fan. The factory if 70mm.
A lot of these older servers were built for low power CPU's and a CPU fan was not needed. Since today these can be replaced for top of the line Xeons for $50 or less, we need to special order the cooler shrouds - which may or may not be possible. So I uploaded a replacement part. I printed it using ABS, but PETG is good too. Don't use PLA as the cooler temperature can go up to 80 Celsius.
The shroud is a snug fit, but screws hold it in place physically by the fact that they are behind the heatpipes. Use plastic nuts (and bolts is available in 30mm length) in case they come loose and start running around in a powered up case... and/or use glue, but I don't think its needed.
Any ABS or PETG
