yup.. 7200rpm disks runs hot ...
since most all of the disk manufacturers now warrant their drives for
1 yr instead of the 3yr or 5yr it used to be ... guess what ... there
was a reason for it .. they have how many sample parts to figure out
their warranty issues
always add one 40mm x 40mm x 20mm fan for each disk right at the disk
or use those drive trays
or use those 4" ( 120cm x 120cm ) fans on the chassis more fans the better
since the mtbf goes down by 50% for each 10C above room temp ..
6,000 mtbf 1yr warranty ...
3,000 mtbf at 35C - 6 month
1,500 mtbf at 45C - 3 months
750 mtbf at 55C - 1.5 months
your disk was probably running at 55C

kinda klunky but guess it works
- air needs about 1" of airgap to work "better" ( like it should )
- air doesnt bend at 90degree turns
