Hard Drive Temperatures: Be Afraid

I recently had a noisy fan failure in my ASUS Vento 3600 case. The particular fan that failed was the 80mm fan in the front panel, which is responsible for circulating air by the hard drives in the front of the case. I disconnected it while I considered my options. There's not a lot of airflow by the hard drives in this case. I've actually had a hard drive failure in this system, which I strongly suspect was due to leaving the front fan disconnected.
The two hard drives are mounted with rubber grommets to reduce conducted vibration noise, a standard feature of many new PC cases.

Avoiding direct metal-to-metal contact will always help quiet drives-- they are, after all, giant hunks of metal spinning at 7,200 or 10,000 RPM. But the lack of metal-to-metal contact also means the drives don't benefit from the significant auxiliary cooling effects of metal contact.
Of course, hard drives don't generate nearly as much heat as your CPU and video card do. They only consume around 10 or 12 watts under load, and around 7 watts at idle. But unlike your CPU, they're generating a lot of mechanical movement, which means friction-- and heat disproportionate to the power input. They still need some airflow to stay at a reasonable temperature.
I often read about users obsessing over their CPU or GPU temperatures, while ignoring their hard drive temperatures entirely. That's a shame, because the hard drive is the most temperature sensitive device inside your computer. Most manufacturers rate CPUs up to 70�C, and GPUs commonly rate to 90�C and beyond."

all i know is that my external, gets hot as hell, and its been clicking lately. I may just need to buy a bluray burner to back up my important files ugh!

I'm not worried. 38C both drives for me and my fan isn't even on.

I like the point he made about the difference between a hard drive and another computer part being replaced. Not everyone keeps entire backups so if you lose the drive you lose all data on that drive.

From the article I linked:

Quote:

At the same conference, another study of more than 100,000 drives in data centers run by Google indicated that temperature seems to have little effect on drive reliability, even as vendors and customers struggle to keep temperature down in their tightly packed data centers.

Mine's been maxin out at 45c today, ever since i turned on AHCI on my mobo I lost all my other drive temps, dunno why

but I remember this one was always the highest temp so I figured it's ok to use as a medium.

failure rates did not correspond to drive usage except in very young and old drives (i.e. heavy data "grinding" is not a significant factor in failure); and there is less correlation between drive temperature and failure rates than might have been expected, and drives that are cooled excessively actually fail more often than those running a little hot.

I wish they called out the manufacturers on that one!!

Conspiracy · 08-10-09

sounds like ima be backing up my external cuz it gets SUPER hot i guess from now on ima jsut buy internals and have an external for temp storage

Conspiracy · 08-10-09

srry for the double post:

but um my external also runs pretty hot during full use. is there a way to get a fan on it to cool it or should i invest in an internet and just use my external for various occasions instead of like all the time?
