Just need to switch over to SSD, PCIe and run some air over them. Ours wil= l temperature throttle on performance, and shut itself down if it gets too = hot. I run them hot all the time for testing, and I've never killed one, a= t least permanently. :-) -----Original Message----- From: piclist-bounces@mit.edu [mailto:piclist-bounces@mit.edu] On Behalf Of= Richard Pope Sent: Thursday, April 28, 2016 11:41 PM To: Microcontroller discussion list - Public. Subject: Re: [EE]:: Seagate 8 TB "Shingled" hard drive reliability aspects. Peter, I concur. I have started liquid cooling my drives on my new SuperCompu= ter. At this point it is only 2 drives. Eventually it will be 20 drives. The HDDs that aren't liquid cooled have a steady stream of cooli= ng air flowing over them. The liquid cooled drives are the coolest at 86 F.= Most of the other drives are running at 89 F. I have one drive that is run= ning at 105 F. Right now it is mounted under the MB tray. I am going to mov= e it to a better location. This is 30 C, about 32 C, and about 41 C. The am= bient temperature is 81.6 F or about 28 C. As you can see the liquid coolin= g does help. My CPUs are running at about 106 F or about 41 C. I have just = started on the liquid cooling. As I acquire funding I will be adding to it.= I am using an Aquacomputer Aquaero 6 to read and control everything. Thanks, rich! P.S. Would anyone like to see pictures? rich!
