Why does it get hot?

ok

Identical in cases and interior cable layout? Perhaps the HDD in box #1 isn't getting the same airflow?

Rather than speculate - get the multimeter - equipment essential to hardware repair - and measure those voltages. Chart of what to measure is in:

Motors run hotter if you starve them of voltage. A motor can be burned out if run > I have a Hardrive that get's very hot and locks up after a time.

works

identical

I've used it with the case open and with a house fan right next to it and it still gets hot. I also tried another HD (27Gb I think) and it also became hotter than I would have expected in a short space of time and I took it off before it could lock up. So the problem does seem to be with my system somewhere.

HD motors are most likely EC (electronically-commutated) motors, so my guess is the voltage is too *high*.

I measured the voltages and and they showed 5v and 12v.

I did measure the voltages and they showed 12v and 5v but I shall look at the link you so kindly posted and find out if I was doing it properly.

I see. I am going to look at the link Tom posted and measure the voltages again, I shall report back. Cheers

Did you measure them under load?

That is, with the hard drive connected and operating.

The plug has to be connected to the drive while the voltage is being tested or the reading could be inaccurate.

But I suppose you already know that.

Easy way to that is with a "Y" connector.

Oh well, it's irrelevant now as I've sold the system and bought a new one with a nice big HD. Yippee!

Low Voltage usually = High Current = Heat..... Swap the supply and see if the problem goes...Also check all the connectors / connections including the Mother Board which could have a cold solder joint on the +5vdc. Good Luck, Ross

Thanks for the reply Ross. I've actually sold the machine now but the person who has it is aware of the situation. I will do as you advise though as it would be nice to get to the bottom of the problem.

In article , snipped-for-privacy@comcast.net mentioned...

The hard drive does not work like an AC motor. It is a DC motor, as is the power supplied to the HD. This power is regulated, and if the voltages fall out of regulation, there is something major wrong with the power supply. So the word brown-out doesn't apply.

The most likely reason for overheating is lack of ventilation. Fix the fans!

If the systems are otherwise identical, I would simply replace your power supply with a dual fan job, and be done with it.

Hahahah funny. Throw money at it.

Hell, throw money at us...
