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?
cpu = 31 degrees, system = 24 degrees. two different temp readings. 24 degrees is insanely cool for a cpu, even at idle. For that to happen the ambient temp must be 0 degrees. What is the ambient temperature of the room the PC is in? because the CPU must be more than the ambient temp.
my cpu temp reading in core temp program was 31C with one hard drive. 24 C with both installed. these are my "core temps of my quad core processor. each has its own seperate reading but thats their average. room temp is about 70 degrees c
24c would be 5 degrees above ambient.
I theorize that you have changed the airflow pattern and more air is hitting near the cpu. You could try removing the new hdd and seeing if your temps reurn to their previous norm.
