What you are saying doesn't make sense... Yes, the block is the limiting factor when you submerge the rad in ice water, but that is because the act of submerging the rad makes it more effective. Every system has a bottleneck, if you remove one it just shifts to another. I would be really surprised if you could gain 20C by running a different block and pump with the H50's slim rad.
This is true, but that is because we're running loops with larger rads than a slim 120.1.
*sigh* because ruby is holding a constant or as close to as constant of a controlled ambient you can run.
By submerging the rad, your removing the heat exchanger element and going looking straight at the heat pick up element.
When your tubes are cold to the touch... coolant is cold to the touch, yet your system is pulling air temps....
There is something very limiting the system. And i couldnt careless if she was running a overclocked gulftown under there because... those temps are a bit too high for a chilled ice bath.
In short.. ruby could of thrown in an average fish hobby pump inside the bucket... with tubing.. onto a solid copper block and laid it on her cpu and would of gotten better temps.
NO JOKE. So to me that means the direct drive is really limited.
Why would you discount someone else's work unless you have some pre-bias to wish for failure?
1 word..
AMBIENT..
did he list ANYTHING about ambient?
While as ruby has Controlled Ambients... IE. ICE BATH.
Why do you think skinnee always puts a delta ambient? Because he knows without one he would get RAPED by people like me.
You need to document ambient.. and how that ambient is playing with your final temp or the test just doesnt mean anything.
You could open a door and have a swing of 5C on a water system from pulling cooler ambient.
I can build a 120x1 system which would gobble my 120x3 system.. oh.. but i would need to put it in an ice bath also.
You see without what type of work is being put on the system though ambient... its too hard to say this test is valid, or that the drive block isnt severally limited.
There are many factors that make up the total c/w of a cooling system, typically worst block to best block you're looking at a few hundredths of a c/w. Other factors aside, at 200w 5c difference equals around 0.025 c/w.
Schmide.. blocks itself in h2o have its own sub catigory... So you may be looking at a few hundredths of a c/w however in RL it comes out to as much as 7C, and thees on real CPU waterblocks.
The H5O direct drive wouldnt even rank on that ladder.
As YellowBeard once said.. its a great little start.
Its not to be classed with real water because target market is after the air sinks.
You can not throw this system to compare it against a real h2o setup.
It be like you bringing in a ricer civic to the track and racing it against NASCAR cars.
If your gonna put in all that work like add a new radiator, and other sort, as well as replace the coolant, and tubing.. gah.. all that work would of been better invested in a used mid-tier setup.
Last NOTE:
ThermalTake, Zalman, and COOLIT ARE NOT REAL WATER PRODUCTS EITHER!
TT has even earned the name as "Cancer to the H2O industry"
Meaning if u add TT to anything.. your entire system will blow up or meet some unfortunate doom down the road.
