CPU Heat Problem on an hp dl380p
Hello
here i have a problem that i dont understand.
Its a hp dl380p Server with Dual Xeon CPU E5-2690
On a Running Win 2012R2 in Idle State and no CPU usage at all 0,5-1% for Hours CPU1 is on 45-50Degree Celsius and Fanspeed of the Fans of the right side is about 30% CPU2 Gets very hot 75-80Degree and its Fans the 2 on the left side only run at 6%
When i run some stresstest Tools on this server Both CPU´s getting hot and all FANS run about 90% then both cpu´s seem to be run in "NORMA CONDITON" under full speed
But on Idle Mode or at Midrange Operation ie.10% allways CPU1 run very hot and CPU2 allways stay cool.
For me it seems that the FAN Speed controll is overcrosed (cpu1/cpu2) but this is not possible because Fans are diretly connected tot the Mainboard.
All Fans are working and i can see the FAN Spped in ILO
Does anyone have have a idea what wrong here ?
Best regards

Re: CPU Heat Problem on an hp dl380p
What kind of server model is this exactly? On the 12x LFF or 25x SFF models the E5-2690 is not supported because of cooling issues. The interesting thing is how much disks you have in your server and in which slots they reside - in some cases the possible airflow will not be enough to cool down the cpu.

Hi

Yesterday i changed thermal paste oft CPU. But no effect
Then i changed cooling in BIOS ftom efficiant to middle since then temp between both CPU is nearly the same
