Thermaltake ProWater 880i water cooling system
Product: Thermaltake ProWater 880i
Contact Thermaltake
DESPITE the squeeze from high-end air and TEC coolers from below, as well as pressure from fridge and freezer systems from the above, water-based cooling contraptions are still very popular.
Yes, the messy installation coupled with evaporation and infamous leakage nightmares doesn't help the water cooling acceptance, but this product category still soldiers on for its silence and - especially UV-lit - otherworldly glow.
Here's one of the highest-end water cooling systems in the open market from one of the leading names in the cooling world, the recently announced Thermaltake ProWater 880i - a pretty large set, matching the Core i7 965 high-end 12 GB RAM test platform on the high-end Asus Rampage II Extreme mobo.
Pro Water
A lot of stuff in here: copper CPU Water Block with their Advanced Brazing technology; dual fan 24 cm radiator block with dimple tubing for heat transfer and vario fan spinning up to 2,000 rpm; 500 litres per minute pump linked to a 350 cc reservoir; plenty of 3/8-inch cabling with ruggedisation for tight corners, and of course the coolant.
Installation
We attached it to the back of Thermaltake V9 casing where the Rampage was, and, interestingly, it provided for holding the pump and tank on top of the radiator. This was, basically, this becomes a hybrid internal-external solution, where it is outside the often cramped chasis, but is still carried around with the casing as one piece. As the V9 already had two holes for the tubing, half an hour was enough to put it all together
Performance
In a 30oC non-airconditioned Singapore lab: In idle mode, there is some improvement vs the best air cooling fan: we got about 41 C vs 46 - 49 C at 4 GHz in BIOS.
When running the usual Sandra 2009 SP2 CPU tests, the CPU temperature jumped to 54 C, still way better than 66 - 67 C spike with the aircooling like Thermalright Ultra or Thermaltake BigTyp 14. However, an Xpressar equivalent, from Thermaltake too, should keep this all the way below 40 C even at full load. µ

"In a 30oC non-airconditioned Singapore lab"
by this do you mean stood in my underpants in my bedroom?
i would love to have a look at some of these review labs from some of these review sites.
"500 litres per minute pump linked to a 350 cc reservoir; plenty of 3/8-inch cabling with ruggedisation for tight corners" Maybe I'm smoking crack, but isn't 500L/min thru a 3/8" tube around 373 Ft/sec? Where do you put the 7700 horsepower pump that runs this thing? I can't imagine the amount of friction heat the coolant screaming through the tube generates.
When a [mostly] traditional/conditional Taiwanese projects through his struggling/heartless intellect, sophistication of the “cute panda” variety will be the off-spring. How cute … with a trail of broken promises & claims – a “sin against The Father”. To graduate from a toy maker into a tickler of sophistry’s fancies, you need a deep-seated/decomposing intellect, oka cruelty/aggression, but as the WW2 Bushido bullet-stoppers have shown, cruelty alone is blind. A measure of feeling/heart is required for balance/gravity/progress.
The East “sins against The Father” and The West “sins against The Mother”. Viewed as a tree, Eastern culture is the root and Western culture is the foliage. A tree lacking proper roots will eventually fall and without proper foliage, a tree will not grow. As such, those who see modernity-cum-technology as the end-all, be-all, are actually lacking gravity/roots. Without Gravity/Innocence/Love, there is no such thing as balance. That’s why Magnetism was created before The Big Bang and His Sister/Femininity, Electricity, is always there supporting Him. The innocent relationship between magnetism and electricity allows for progress, not zero-sum games.
Intellect, oka the ego, is [futuristic] projection, expressed as I, me, mine, to afford its illusion, a grounding. Without balance/gravity, there is no absolute authority. All an ego needs to be authoritaive is to spout some futuristic scenario and control is his but that’ll turn into abandonment once its lack of real authority is exposed. Control-cum-abandonment is the result of the lack of true balance. That is how the blind leads the blinded. False authority through a baseless foundation/root. [In Reality, femininity is power whereas masculinity is the principle which is why women do not need to project power and men do not need to project authority. Those who do, are projecting/accumulating for their vacuum].
Errors are excellent teachers but not when the aspirant refuses to learn and keeps repeating the same error. Like mistaking a fabled toy maker, full of Eastern promises, as an innocent intellect whilst remembering that electricity or magnetism on their own, lacks innocence/authority.
@Jon:
Although your back-of-the-envelope calculations on the flow rate of the pump look to be about right, you are are mistaken about the size of pump needed.
if my university fluid mechanics serves me correctly, 500 l/min = 8.3 l/sec = 0.0083 m^3/sec = 8.3 x 10-3 m^3/sec
3/8in = 9.5mm diameter = 4.75 x 10^-3m radius
(4.75 x10-3 )^2 x pi = 70.84625 x 10^-6m
(8.3 x 10-3 m^3/sec) / 70.84625 x 10^-6m = 117.15 m/s
By this rough calculation, it shows that the fluid is flowing hella fast (mainly cos its flowing through a small diameter tube!)
117.15 m/s roughly equals the 373 Ft/sec I had originally calculated. If you take it one step further and calculate the work required to push fluid at that velocity through such a small hose, you will come up with about 7700 HP. You claim that I am mistaken about the size of pump required, yet you provide no calculation to back it up. I'm left to wonder if you've hit the same crack pipe as Ah Sorr.
@Jon
7700HP = 5,741,889.01W or 5.7MW.
Whichever way you look at it, it just looks wrong.
I tried to provide proof, but I forgot the rest of the calculations.
I also forgot to add the following:
"From the description of the 3/8in tubes with ruggedised corners, it seems that the coolant will be flowing in a lamilar flow fashion with little or no boundary layer.
My guess is that some form of nozzle is used to drop the pressure and increase the fluid velocity."
Ah yes... "it just looks wrong." How can I possibly respond to such a compelling argument?
