Hitachi enters watercooling market

See the link on the Inquirer:

Might be an interesting contender to the Reservator, if indeed the claims are true and it all works as advertised?

nice find.

at this point in time, watercooling is a market where anyone can enter and make a quick buck (or 1000). the hitachi kit looks like no exception.

for spcr purposes it is definitely too loud, 24dba is the noise level for what i assume is the unit by itself, once you put it in a case it could be even louder (turbulence etc). also, 5 years maintenance free is a bit dubious unless they have a magic pump (on par with eheim) and a dust filter.

they also chose the poorer of the 2 most popular radiator styles, whether or not this will hurt performance is yet to be seen.

Looks nice, shuttles are renowned to be beastily loud! 24 dba is good for a shuttle although yeah by our standards its pants!

I impressed it's so compact and fully sealed, that should appeal to quite a few people.

You'd want a pretty strong fan to get decent performance with a radiator that small though.. but I guess the pump doesn't need to be all that beefy with such a small closed loop.

I wonder how long it'll be before Intel brings out their own watercooled stock cooler. (can't be too far off if their processors get any hotter)

"Maintenance free for five years" :shock: :shock:

5 YEARS!!!!!! beyond the useful life of the system so water cooling without maintenance... :shock: :D

5 years!

i doubt it. i think corrosion will become a problem well before then, it's happened to brass components over lengthy periods of time so i don't see why the same wouldn't happen to bare copper. what type of coolant do they put in it? if it's just plain tap water then algae will be a problem too

In a sealed loop its probably a soup of distilled water and corrosion inhibitors. 5 years is probably an overly conservative timespan even. Other sealed systems like that in industrial chillers vhave life spans of 10-20 years.

But looking at that HSF you have to wonder..why not heatpipes? for that distance they'd be cheaper and more effective.

very good point. heatpipes would not only be cheaper, but they'd also be even more maintenance free and reliable as you wouldn't have to rely on a pump.

i'm not sure about effectiveness though. depending on the design of the waterblock on the cpu, moving water can do things that a heatpipe can't, e.g. jet/slot impingement heat transfer.

it's an interesting step in a good direction, nonetheless :)
