Hello,   I took a look at the heatsinks listed for the R630. Y8MC1 is listed for the higher TDP of 160W.  The only alternative was a lower TDP of 120W. All the heatsinks listed for the R730 show a TDP of 165W. I'd expect that Y8MC1 is the part number you'd be looking for. Let me know if that helps, or if you have more questions.
Hi! I want to know what heatsink should I use with E5-2697 v3 in a Dell R730 or R630. For example in Dell R730 I have currently YY2R8, but there is also another heatsink NGC09 which, as per some sites, seems to be for 165W, but I could not find this information on Dell site. Same issue with R630, I currently have in that server a heatsink H1M29. When I installed E5-2697 v3, even if the server recognized the CPUs the vents were running almost at max. I assume I need a different heatsink, but which one? Thank you!
