I noticed that too, but having looked at the motherboard I don't see a VRM slot as with the PIII class boards on the 1400SC and 1500SC.  I am ordering a second CPU from a pricewatch.com dealer and getting the heatsink, fan, and clips from Dell.

Thanks for the info.  Do you have the DELL part numbers for these items? 

I wonder if the boxed processor heatsink, fan and clips will do the job. 

I think that you got to be careful about the CPU since it has to match the existing one. In particular, you need to look at the sSpec number which is located on the bottom side of the CPU assembly.  FYI,  mine has the sSpec Number  SL6M7  which corresponds to Intel Product Order Code  BX80532KC2800D .

The boxed processor's heat sink sits properly on the processor but the plastic clip extends way left and caused the hood to slant. Also, I couldn't find where to plug the fan. I ended up ordering a heat sink and clip from Dell.

 

Do you happen to have the DELL part numbers? does the heatsink comes with the fan as an assembly or I have to order them separately?

Thanks

Hi,

These are the Dell part numbers for the PowerEdge 1600 SC heatsink:

7R181  Heatsink Assembly (Includes heatsink and fan) 
83MGJ  Heatsink Clip  (2 required)

Dell spare parts can be reached by phone at 1-800-357-3355

Thanks for the information. I'm just confused that since the boxed heat sink works properly, why did you want to order both heatsink and clips from Dell? Why not just a pair of clip?

Thanks for the reply.

I think that DELL's heatsink is a much better fit since the fan blows the air perpendicular to the motherboard and this fits the overall case air flow design in which the hot air from the CPU is picked up by the system fan.  Both CPU fan and system fan work in a way as a coupled system.  On the other hand, the boxed CPU wind tunnel design has the fan mounted so that it blows the air parallel to the motherboard.  In this case the flow of the CPU and sytem fans will not be connected. 

The more important part is that the boxed CPU fan socket is of a different type and you won't be able to connect it to the motherboard.  You just have to go with DELL heatsink & fan assembly  and clips on this upgrade. 

Very useful information.

Thanks a lot.

wow, $65 USD for the set of two fans and sinks and four clips. Now that's a spendy cooler! (the GlobalWin Xeon cooler is only $15 including clips) I only need one set, anyone wanna split the package with me? (One fan/sink and two clips for $32.50)

I'll split it with you.
