I added a 7200 sata rpm 1tb drive in the next to bottom slot of my computer. I have a 5900 sata their before the addition sitting in two slots up with a couple slots from the very top of the hard drive bay left over. Cpu temp reading was 31 degrees on standby with just the 5900 drive. With the new hard drive in as well for 2 total, system temp is now 24 degrees. I really don't see how adding another hotter hard drive to the case could cool my temps. I have one fan in front of the hard drives in front of the case just like when I had only one drive in there. It's a Nzxt m59 case. Any thoughts?
