^^Doesn't matter, their blocks are still ugly as sin.

Wow!! Looks like it might be time to replace my RASA.

I may be replacing mine as well.

Not all of the blocks are made in Asia bud smile.gif EK's aren't, Heatkiller's aren't, AquaComputer stuff isn't.

Also what I mean by 'cheap asian made' blocks are things like Swiftech, or this Rasa garbage. Look on the insides of the block and you'll notice a flat slab of copper with just a bunch of straight cuts - nothing fancy, and the build quality is inconsistent and very poor. Open up an EK or a Heatkiller, and you'll notice how much work has gone into water channelling and design inside of the blocks.

Once you own a few different brands you'll see...

Really, it's all down to looks for me. They all perform relatively close to one another. That's why I chose the HF instead of the raystorm. thumb.gif

ive had the M6 since EARLY DECEMBER, and mine is a 'prototype' sample. i love it to death. keeps my 3930K sub 25C at idle, with it bottoming out at 19C.

Except, any waterblock or even stock Intel HSF will keep whatever 32nm CPU you've got in there sub 25deg on idle wink.gif Especially when you open HW Monitor when you first boot - and don't run any intensive apps before loading HW Monitor. My 980x at 4.48Ghz will cool down to 16 degrees on idle in the morning when I first boot her up.

That being said, most of the blocks do perform fairly similar in a CPU only loop within 4-5 degrees from top to bottom at the extreme.It's generally when you add in other blocks that you notice the difference when everything is pumping large heatloads into your loop.

Too bad the Raystorm and the Apogee HD are at the top of the CPU block game at the moment rolleyes.gif

Please see here and here. This one is pretty interesting also.

You'll notice the Koolance is not too bad either. The 'flat slab of copper with just a bunch of straight cuts' was simply designed with cost in mind. That's good engineering if you ask me. This is compensated with heavy and complex machining of the Acetal block that comes on top of it, which is much easier and quicker to machine than copper. Simply a different strategy, and the numbers will tell you it works

Going on a tangent for a moment... I did ask an engineer, specifically a dude with a masters in CFD from Cranfield. He said in an ideal world you'd want to dump the water right onto the cpu slug. No material in between the water and the cpu! Thus the least amount of copper the better. The copper slug is just to even out the heat transfer, so the more copper there is, the more it gets in the way of the transfer itself. In this regard XSPC is on the right track.
