I forgot to mention that there is an air intake on the side of my case where the drives are, so it's perfectly possible for room air to blow across the drives, thus reducing their temperature to something closer to the room-ambient temperature (which is about 23-25C right now) and lower than case-ambient. Good airflow across hard drives is vital to their temperature and thus life expectancy. Not that any of this is at all pertinent to the conversation. But the original poster asked what a good operating temperature for a hard drive was and I answered that. The construction of my personal system is largely immaterial. -- Ben Steeves _ bcs@xxxxxxxxxx The ASCII ribbon campaign ( ) ben.steeves@xxxxxxxxx against HTML e-mail X GPG ID: 0xB3EBF1D9 http://www.metacon.ca/bcs / \ Yahoo Messenger: ben_steeves
