Harrison, My boot drive is a SSD. Since SSDs have a limited number of write=20 operations before they go bye-bye I have removed the Swap file and=20 dedicated a hard drive as the Swap partition. I also have a dedicated=20 Applications drive and I put all of my programs on it except for the=20 ones that just insist on being installed on the C: drive. My SSD is running at about 90 F and it is air cooled. I won't be=20 liquid cooling it. I don't like letting any electronics to get above 120=20 F and then you can count on the MTBF going down. At 100 C or 212 F the=20 MTBF will be about 81 days at a starting point of 250,000 hours or about=20 28 years MTBF at 25 C or 77 F. 100 C is about where shutdown will kick=20 in. You have shorten their lifetime. Yes, it would be covered under=20 warranty but is it fair to the manufacturer or the rest of us to have=20 them replace it when it has been abused. I don't think so. Thanks, rich! P.S. This is my opinion. rich! On 4/29/2016 5:22 PM, Harrison Cooper wrote: > Just need to switch over to SSD, PCIe and run some air over them.

I have started liquid cooling my drives on my new SuperCo= mputer. 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 coo= ling 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 r= unning at 105 F. Right now it is mounted under the MB tray. I am going to m= ove it to a better location. This is 30 C, about 32 C, and about 41 C. The = ambient temperature is 81.6 F or about 28 C. As you can see the liquid cool= ing does help. My CPUs are running at about 106 F or about 41 C. I have jus= t started on the liquid cooling. As I acquire funding I will be adding to i= t. I am using an Aquacomputer Aquaero 6 to read and control everything. > > Thanks, > > rich! > > P.S.
