Temperature Increase With Larger Drive?

[Rhughes]

I just put a 200GB drive in my new R10 to replace the original 80GB that came with it. There are both the same type from Western Digital, just different size. The R10 was running 38C with the 80GB. It now runs 43C with the 200GB. Do larger drives really cause that much increase in temperature?

Short answer...Yes

With more platters, higher torque motors are needed to turn them, increasing heat in the drive. Another possibility is the 80gb drive might be a 5400rpm drive, where the new one is most likely 7200rpm. Higher rotational speeds usually mean more heat.

43C is still well within specs. I raised my Tivo's by setting washers under each feet to raise it 1/2 inch which reduced the heat by a few C's.

I built a 3" stand for the R10 which allows free airflow on all sides and top/bottom. I was thinking that more platters might cause more heat. Thanks for confirming that. Yes, I am happy with 43C. I was even more happy with 38C. :)

Unless something is wrong with the 200GB drive, I don't think the drive is the only contributing factor. Are you sure the room temperature has not changed?
