This is more like a survey but still is a question.
What do you say the best temps for keeping components are?
This is for a temp/fan controller I have and would just like to get the experts input on this.

Example- the hard drive, I don't want it to get too hot but yet I don't want a fan running on it all the time.

Hdd safe operating temps- between ? and ?
Cpu safe operating temps-
Chipset safe operating temps-
Case safe operating temps-
Power supply safe op temps-

Seagate sata 250gb hard drive.

You will love the p180. It is big but awesome. I got the nexus 120 fans to replace the antec ones. Man are they quiet. I used the zalman 7000 to replace stock fan. I have a gigabyte 6600gt fanless model and replaced the stock chipset fan with a zalman passive heatsink. The only problem is that the gig 6600 extends into the side fan and you have to mod it a little. I have 5 fans going. The top fan,back fan, cpu fan, bottom fan and side fan. When all five are going full blast I can barely hear it and what I hear is the zalman but barely. I have a digital doc 5+ fan shutoff which is awesome and fanmate 2 to control fan speed. Temps are great and when all fans are off except cpu which I have on all the time I can't hear a sound. I have the zalman 7000 turned down with the fanmate to silent mode and it is silent.
