Heat and noise from a CL56?

I am really close to buying one. This is scary

Heat
I've read that the back bottom gets warm after about an hour, and that the wrist rest gets "slightly warm."

How warm does the bottom get? Warmer than you would want to be in direct contact with a newborn's skin?

Same as above for wrist rest warmth.. "slightly warmer than the rest of the notebook" or "you could warm your hands on it in the winter", etc. ?

Any sorts of silly analogies to warmth would be greatly appreciated.

Noise
What RPM drive do you have, and..
How is the drive's audibility during seek/access compared to idle? Loud ticking? Muffled? Inaudible? Again, any sort of description would be more accurate than "pretty quiet."
(I've read in multiple places that the drives [even 7200rpm] are near-silent while idle.)


I hear the fan isn't bad at all; I can certainly live with a fan that usually spins up under a stressed environment. (High ambient heat, gaming, etc.)

I'm mostly concerned with "how warm is warm" and "how loud is HDD seek/access." Any sort of descriptions are greatly appreciated.

Thanks

why are you going to be putting a lappy on a newborn baby? wouldn't that constitute child abuse?

Um, that was the easiest thing I could think of to differentiate between what I would personally consider warm vs. hot.

The CL56 is very well designed for thermal management, the parts that get warm do not get alarmingly hot and the noise is kept to a minumum.
Only drawback is that the radeon 9700's clocks do not exceed any other thin n light platform, but performance still quite good.

First and formost...ALL laptops will get warm no matter what...that being said, if your on a rather low clock frequency, it will get slightly warm. I have a program that states the current temperature of the hard drive. When your on low power mode, the harddrive temp stays ~38 celsius. The Compal CL 56 has an aluminum "tray" that's between the keyboard and the notebook components. This does a great job absorbing and dissipating the heat. When the laptop is on High power mode, the hd temp never goes above 45 celsius....and this is with the laptop being on my bed.

The heat doesn't get "uncomfortable," but it still does warm up. The fan almost never comes on in low power mode. It's so quiet even when it's on that you can hear the harddisk spinning more than you can the fan...and the harddisk is barely more than a whisper. It will come on, however, when your doing processor intensive tasks. Even then, it doesn't get loud or anything. It just has this slight "whir" to it, letting you know that it's working properly.

5400 rpm HD. I hear that the 7200 are as dead silent as the 5400.

speaking of hard drives, hypersonic has a 60GB 7200rpm that has like 24/7 support or something, they offer 2 60GB 7200rpm HD's...what is the difference between the two

the new one is the "enhanced" hitachi which is in very short supply. I can't get it here in canada and there is no ETA. It's just the exact same specs, just probably some heat improvements so it can be slated for 24/7 operation. You should be fine with the regular hitachi.

the palm/key rests do not get warm/hot

after extended use the bottom rear section of the lappy gets warm

artic silver 5 (i believe only hypersonic uses it, though you can apply it yourself--check w/ your warranty of course first) can reduce the heat of the cpu (better heat dissapation to fan or something like that)

Heh, not quite. AS5 is really only used because it transfers heat better. More heat to the HSF means less heat on the CPU which means you can overclock higher Better transfer of heat is not less heat, though, so it wouldn't really make a difference in this case.

Yeah, unfortunately the guys who make AS5 have not found a way to get around that annoying first law of thermodynamics.

To get less heat, you must use more efficient low power consuming components (lower clock speed dothan, lower rpm hard disk, lower clocked gpu, etc). You can find/compare hard drive power usage/dissipation specs on Hitachi's website (I know I've posted them on this board before).
