The BIOS of the server motherboard is TYAN S7045 (S7045WGM2NR) supports only the following processors:
TYAN - Motherboards_S7045_S7045WGM2NR
CPU Support - Intel Solution:
TYAN – Intel Socket LGA1356 CPU Supported server boards
All the models belong to the first generation; the version 2 are not compatible with your server board.
In regards the cpu fan, the models available are below:
Passive for rack mount chassis: STS100P (Height:1U, TDP: 95W)
Active versions: STS100C and E97384 (Height:3U, TDP:130W)
Both fan models are compatible with LGA1366 and LGA1356 processor sockets. The fan model BXSTS100C is not recommended for LGA1356.
Thank you for all the information provided. The good new is you are not claiming that LGA 1356 does not exist.
As to the very bad news you provide. This is where, once more it gets confusing. Your very first link to Tyan when I select my version of that board states under Supported processors: Intel Xeon Processor E5-2400/E5-2400 v2 series processors. Which does not yet contradict my decision for a E5-2407 v2 However, your second link does not include that CPU; which obviously is what you are saying.
So after all the time I had spent trying to sort this out, I guess I will first get back to Tyan and see what they say.
And I thank you for the clarity about the cooling solution.
