SAS HDD temperature

Thank you for your prompt answer. I know that. I said that just to put the HDD temperature with the fans at full speed.

My question was about the 50°C and 53°C temperatures. Are they normal? too hot?

Sorry if I was unclear.

The fans will run at full speed when you take the cover off, regardless of what is in the system and what it is doing.

I would say that 50 is on the hot side, however, normal can also depend on the make and model of the drive, so I don't know what would be considered an unsafe temperature for that drive.  For example, in one Dell OptiPlex, Seagate drives are not officially supported in a two-disk configuration, because only certain Western Digital drives run cool enough for the system's cooling design.

To perhaps help put things in perspective though ... I have a 3 disks in my computer (two HDD's) - one nearly constantly running a VM at 31C and one currently idle at 24C.

On the Seagate link, gives temperature specs....

Agree, these drives are bordering on hot,  50 degrees is at the  top  limit for these drives as per Seagate specs. I get concerned if my server drives are over 30, worried and adding fans if near 37; then again Google's study doesn't backup my belief in cool running drives ( the link below). Also motherboard/drive temperature circuit/sensor are not very accurate.

To let you know what a hot drive is...

In 1992 had a client who had to have a raid 5 , drives were full height SCSI,  just over 2 gig; heavier than a brick.  Average life span 4-5 months, no drive lasted over 7 months. Another tech and I pulled out a bad drive, which required leather work gloves to handle it, drive had no warranty, so out of curosity (more like to much time on our hands)  we cracked an egg, dumped it on the drive, which produced a perfect sunny side up...  the drives had to be very close to 100 centigrade, and that was with added fans.

Thank you both for your help.

This is what I was thinking... But as everything is setup as Dell recommendations, I was not sure.

I don't see how I can add more fans in this tiny server. Do you have a recommendation about a software that can adjust fans speed?

The other solutions I have is opening the case to have the fans running at full speed, but I am not convinced about this solutions...

Do you have some suggestions?

Thanks again!

If drives are supported by Dell on this server, then I would start by updating the BIOS ... this server does not have an ESM that controls fans and is handled by the BIOS.  The release notes mention calibration of front and HDD fans as part of the updates ... possible that more efficient/effective fan algorithms are used in later releases.  The fan you installed was the part number prescribed by Dell for it?

Never tried fan speed software on servers. If you do not mind the noise, you could bypass the case switch.

"I don't see how I can add more fans in this tiny server". I have yet to deal  with a server which you could not add fans to  other then 1u units... worst case, you supend them with plastic ties..not pretty but it works, and would be quieter.

Thank you for your answer.The BIOS is already at the last version. The fan I installed was the part number recommended by Dell.

Hi pcmeiners!

Sorry for the very late reply.

Thank you for the tip to add other fans!

I will see what would be the best solution!
