I am using the SilverStone DS380B case, an AsRock C2550D4I (With ECC RAM, not that it's as relevant to this question) and with seven drives mounted in the chassis. I am using the stock fans that come with the case, two intake fans that blow over the side of the HDD's and one exhaust fan at the back of the case. I got a SMART warning that one of the drives was too hot when doing some intensive writes, so then I looked at them all and saw that one drive was at 61C and two more were at ~55C. I immediately stopped the process that was running and the HDD's quickly cooled down. Fortunately I haven't found any permanent damage (I have another drive in standby in case) but what I was wondering: where would you recommend I go from here? The case doesn't have more fan slots. I can buy three better fans if that would help very much, or is just poor design of the case? I've read a couple places now that people have had this problem in the past running a NAS in this case.
