ThinkSystem SR550 Fan Speed

2020-12-15, 11:09 AM

We recently bought a new SR550 Server. Overall is a good machine, but there is a problem with fans. They are always running at 47-55% speed and it is very loud. There is only 1 CPU installed, no heavy tasks running (as of right now it runs clean 2016 Server Standard). XCC shows CPU Temp as 34-35C , Ambient 29C (I assume inside server, because room temp is about 24C). XCC Version is 2.60. I tried some power settings through BIOS, they don't change anything. I also did not find any other setting that might affect fan speed. Is it a normal behavior for SR550 fans? If not the only thing I can think of is that there are only 3 fans pre-installed out of 4 and maybe installing additional one might lower overall speed.

Just for comparison we have another HPE Server in the same room. Its CPU runs at 40C with much heavier workload, same ambient 29C (internal) and fans never go higher than 15% speed. Although it has 4 fans.

Hello  you have one CPU configed so that default come with three FANs. In order to dermine if FAN speed is work as expected or not, support ticket should be opened to review the log in details. The Speed of FANs not only relate to CPU and ambeint temp, do you have more options installed like high number of disks? for example the 12x3.5 models might need higher fan output for additional cooling

Hi, thank you for reply. We have 12x3.5 model indeed. However only 8 drives installed, and only 2 of them are currently operating (online). I created a support ticket, so gonna wait for it I guess.
