The good thing about the Intel® BXTS13X is that it does not use screws as the BXSTS200C and complies with the TDP of the processor you have. However, I am just wondering regarding the motherboard model you plan to use. Did you contact the motherboard manufacturer regarding this?
There is also BXTS13A and RTS2011AC but they use screws.
just realize that my motherboard (SuperMicro X10SRL-F-B) uses a narrow LMI and regular LGA2011 will not fit.
I will look for more options.
BXSTS200PNRW is passive, narrow, copper based, 1U height, up to 130W TDP.
It seems there is another model here: Narrow ILM v. Square ILM - LGA2011 Heatsink Differences - ServeTheHomeServeTheHome – Server and Workstation Reviews
That's right.... that's what I figure out after buy 2 collers... but I found the Supermicro SNK-P0050AP4 and it is working now. I would prefer to buy from intel, but my research was not bringing much information.
Thank you for the replies.
