I was looking into a new Seagate 1TB SSHD then I read reviews on amazon and newegg every 3 out of 4 reviews was a failed drive that needed to be RMA'd
it's got 5 fan slots! 2 in the front 2 on the side panel 1 on the back and a HDD fan slot.
In the past decade i have used almost exclusively Seagate HDDs and i never had any problem. The only HDD that failed was a 1TB Barracuda bought in early 2008, which had bad sectors 5 and a half years later. I replaced it with another 1TB Seagate disk and i have no problems until now.
