Hitachi has a watercooled laptop out~

that is one small a55 pump..
how much gph you tink it does?

[safemode]

it's been on hardocp's front page most of the day... and reported about before too..


it's pretty nifty. but without forced airflow over the radiotor ...i dont know how well you could expect something like to perform. It's not like air can pass through it.. it's gotta pass over it. Which means even with it's small surface area due to being just some tubes.. it's only getting part of that since it's attached to the lid on at least one side of it.

Are they actually passively cooling their radiator? I doubt it.

[[EG]~NaTz~]

probably small fans in teh bottom and top that just pull air in behind the plactic and up through and out the top...

[masitti]

That's pretty sweet... although the laptop is a brick.. cool idea. Any word on overclocking it? ;)

[mfpmax]

Yeah, Toshiba was gonna start watercooling laptops, and I think that was news from last year or earlier this year.

Well, they are able to nearly passively cool XP chips in laptops, and Pentium4 chips in laptops.. so why not watercool them. :)

Thanks for the Babelfish translation, it helped out. Sorta. ;)

[The Spyder]

Well..... its silent..... no fans....... wiht a 1.8 intel processor....... not bad~

Lol, I never said it'd be any easier to read. ;)

Mobile processors give out nearly half the wattage as there desktop brethern though, :)

I stand corrected. I knew something wasn't right there... :)

[Omega Destroyer]

Yeah that looks cool, but as mentioned above there is little surface area to cool the water, and I wonder how much airflow there is as well.
Plus it's not like water is really light, so if they were to add a lot of water it would increase the weight of the labtop considerably. And if they don't add enough the water will be too hot, and won't have enough time too cool down. I guess light weight is not their goal

[The Spyder]

well~ with how much is shown by the pics~ it should not weight more then a full Dell 8200

[Penguin4x4]

And what about the water sloshing? :D:D:D

If the system is filled correctly, there should be no sloshing - although that would be quite a site to see (or hear)... :beer:

$2000 Water ballon fight any1? :D:D:D:D:D:beer:

[The Spyder]

me me me~ if you pay~~~~ :)

[Frodo Baggins]

s'cuse me, but what's the point? Water cooling, as far as I''ve seen is only done to cool really hot processors that are overclocked. I mean, if your not gonna oc your laptop (i havent' heard many people do that) then what's the extra cooling for?

The only thing I can think of is that it'll increase the lifespan, but then again, in 10 years, which a normal laptop can last, i doubt many of us will be running 1.8s frequently

Just remember that a normal car engine will run at what? near a hundred degrees? this is hot sure, but if it's meant to work that way, and it works that way fine, then what's the point of adding sophisticated doowacky?

[The Spyder]

silence........ pure udder SILENCE.................. i mean have you HEARD a p4 laptop dude? They are LOUD SOB'S!!!

damnit i just bought my rig!

hmm...no I've been out of touch with comps, my dad has a toshiba 200 mhz Pentium :rolleyes:...what's the sound rating on a laptop, like estimate? it owuldn't be like loud as like an everflow or a delta would it?

And sheesh, what a price for silence

[Cheng]

The point is heat.....my dad has a 1.7ghz P4 laptop and it will easily burn your lap, he has to put a chessboard under it.....

[safemode]

funny thing is, mobile xp processors put out about 20% less heat than mobile P4s. But that's somewhat true of their desktop cpus as well.

I would recommend water cooling to anyone who knows enough about computers even if they didn't overclock. Air cooling current cpus either stresses the cpu or is really noisy. On summer days you'd be lucky to be able to run your computer without overheating with even good air cooling. Water cooling wont have problems like that until it's really hot. Water cooling just simplifies things if you do it right and it's quieter if done right and your hardware will last longer if you do it right.

If you're worried about cost then you have to be worried about longevity of the hardware and running your cpu 10 degrees below max half the year isn't a good way to get there. cpus and hardware shouldn't have a max life of only a few years. Even if you've got money to waste every couple years and you dont use it anymore, it doesn't mean it's ok for it to be dead by then.

There's a reason why water cooling has exploded in popularity recently and it's not because of the number of people doing massive overclocks has increased. It's because cpus are becoming too hot to be sufficiently cooled by air hsf's running at their spec'd speeds. Let alone trying to bump it up even a little. Water cooling is becoming a necessity like hsf became a necessity with the pentium 166 and up. I'm rather sure it already is a necessity for most current cpus and that the only thing keeping air cooling alive is the difficulty with switching and no oem support from anyone major. Air cooling most crrent cpus has become outrageous but people are made to believe they should put up with it when they shouldn't.

People have 486's that still run perfectly fine. I doubt 13+ years from now people with air cooling are going to have many Athlon xp 2000 systems running. Not with the frequency of chips dying from heat stroke. That will only increase as time catches up to thermal damage of running your chip so hot that it turns itself off in the summers.
