Hi everybody,
i have installed the board in a Chenbro 2U rackmount chassis. Firmware was updated with S1200RPL_S1200RPO_S1200RPM_SFUP_BIOS02010004_BMC111_FRUSDR106.zip. During the updates I answered the SDR related questions: yes I have SysFan 1 - 4, Yes I have a CPU fan, and chassis intrusion switch and NMI button. Remaining problem: while the integrated BMC web console shows the highest temperature at 35°C, fans are at 4500 rpm. Also, there is no change in fan speed when I open the chassis (trip chassis intrusion). Fans appear to be at 100% all the time. This is an old and often discussed problem. When the update utilities detect an "Other Chassis", they program fans for safe cooling.
The problem can probably been solved by adjusting sensor / fan settings e.g. in the S1200RP.SDR file. BUT: I have not been able to get reliable first hand info about these settings. All I found were pieces of info from the forums, mostly regarding the S5XXX series of mainboards.
I read http://download.intel.com/support/motherboards/server/sb/g84364004_s1200v3rp_tps_r1_3.pdf but chapter 6.10 and appendix B aren't of much help. (BTW: the acoustic management part in BIOS offers only an "auto" setting, I cannot choose CLTT or OLTT.)
Is there a documentation of the SDR on S1200RP boards available? Maybe even a hands-on guide ("change this and achieve that")?
Thanks for your insight.
Dirk
