unraid_2021 Posted January 16, 2021 Share Posted January 16, 2021 Hi i have just setup my unraid build and I am seeing very high disk temp. What level of temp. one should be generally seeing and what point should I be worried about Quote Link to comment
JorgeB Posted January 16, 2021 Share Posted January 16, 2021 Aim for 40C, 45C tops, those are definitely too hot, you need to improve cooling. Quote Link to comment
unraid_2021 Posted January 16, 2021 Author Share Posted January 16, 2021 at the moment my case is open so ample of air flow ...any suggestions on what to do about cooling? Quote Link to comment
JorgeB Posted January 16, 2021 Share Posted January 16, 2021 Open case isn't good for disk cooling, you need good airflow and fans moving air over and around the disks. Quote Link to comment

Close the case and recheck temp. All airflow through the case must pass by the drives, if not, you need to seal up any openings that allow air get through without cooling the drives. If in doubt, post a picture of your case, lid on and off, with arrows showing fan flow direction. 1 Quote Link to comment
unraid_2021 Posted January 16, 2021 Author Share Posted January 16, 2021 ok thanks this is how my current drives are in the bay , the case is R6 define, shall I have more spacing between them to improve air flow Quote Link to comment

We need to see the overall picture of how air moves through the case. 1 Quote Link to comment
Frank1940 Posted January 16, 2021 Share Posted January 16, 2021 (edited) Basic 'rule of thumb' for cooling servers. All air entering the case should first pass over the drives. All fans behind this(these) entry point(s) the drives should be blowing air out of the case. Any fans between the entry point of the air and the drives should be blowing air into the case. There should be one point of entry for air into the server. (although this might be the entire front panel of the server--- this is usually the norm for most computer cases.)

Vr2Io Posted January 16, 2021 Share Posted January 16, 2021 (edited) One major isssue was the tray design problem, disk bottom side around motor was hottest area, but the tray just cover it. You can do some test without tray, just keep air flow at disk bottom side. Edited January 16, 2021 by Vr2Io 1 Quote Link to comment
unraid_2021 Posted January 17, 2021 Author Share Posted January 17, 2021 The airflow is as above. Currently temp. is at 40C (parity), 40C (Data), 36C (Data). Yesterday Parity build was running and now completed Quote Link to comment
