But it isn't. With a small flathead screwdriver and a few minutes, u can get those brackets off and then pop them onto the fan from a dell dimension!
If you cant get them from Dell, I know ebay has them. Also, u could check a local computer repair shop, as they prolly have dead dell carcasses laying around or even the fans pulled out for sale.
I know it was a while ago (2006) with your post but I also have a 1400 and want to insert a second CPU.
I swapped the m/board from an american Optiflex machine and the VRM off the original m/board in the 1400 was thrown - a chip had blown and melted.
Anyway, the place for the VRM on the replacement board was not in existence, so I had this VRM spare. All systems still worked as normal...!!!
I'm still trying to work out what I need to do to add a higher speed second CPU. I thnk it is best to just buy 2 together, matching etc..
Any ideas on the fastest CPU that this board will take..??
Yeah it's been a while since I had that computer, but here's what I remember...
There are two submodels of the Poweredge 1400SC: One that will only take Coppermine and Coppermine-T CPU's. That effectively limits the max clock speed to 1100MHz. This is the model I had (pictured).
The other model is not as common, but the motherboard will accept the quite snappy Tualatin series P3 CPU. Those went up to 1400MHz, although I do not know if the Dell BIOS will accept all models of this CPU.
