August 19, 20241 yr I purchased a set of new 5x EXOS 6TB 3.5 enterprise drives from newegg for a great price. I installed in a new Jonsbo N4 build. After just a few minutes three of the five disks heated up to over 60 degrees (64, 63, 61) and the other two were in the mid 50s. This is with ZERO load (on but no throughput). This is seriously hot, and while the user manual states they can run at up to 60 by design I am concerned about this. I tried a few old 1TB seagate drives, and those ran in the mid 30s and 40s. Much better! So I went to pick up a few 6TB Seagate ironwolf NAS red drives (I already have two in my PC, so can swap those in) to replace the EXOS drives, coupled with a fancy Noctua fan to replace the measly Jonsbo fan that really wasn't putting out much of a draft. I installed the fan to see how that would work out. Immediately the system is much cooler, and disks run at 35C BUT my system is now LOUD as I made a poor selection of MOBO without PWM fan support (an N5105 - I will tackle that in a separate thread). So my question is this: Should I go ahead and do the swap out of the EXOS drives and use the NAS drives instead? It seems to me that the EXOS drives are really meant to be in an enterprise server room with great cooling and super loud fans. I would imagine the NAS disks would run naturally cooler, and perhaps be more power efficient, and I could then drop the case fan speed (manually of course unless I switch the motherboard too). I can return the EXOS drives easily. Thoughts?
August 23, 20241 yr Hard to imagine they'd get that hot unless the fan somehow isn't running or really throttled. The 6TB ones draw more than the bigger helium ones but still should be OK at 7-10W....
