Bummer that it's through that forum and not directly from Feser. However, that being said, i'd still love to see some reviews and benchmarks from Skinnee. I think he's hinted at actually having a couple in his possession, but I think he is bound by NDA from posting any info until release date.

I just want to see some real data. There is so much speculation as to how well these will perform and what cost will be. From the hype, they supposedly outperform normal rads 3:1, but again...all speculation. I've seen a few minor details as to how many channels the rads run and the flow-rates, so very curious to see real-world result data.

^+1 I couldn't say it any better,we may have to wait for some real test on this,got some space for 140MM RAD (GTX 580 coming soon) :)

Trust me, if they really end up being as good as rumors say, I will be investing in (insert appropriate Admiral radiator number/size here) for my loop. :)

Stainless steel? I can understand wanting to get away from soldering, what with the EU having to comply with RHOS...but why introduce galvanic corrosion and requiring folks to use inhibitors in their cooling loops? I don't care how stainless the steel is, it will still oxidize-reduce with the copper in your loop using your fluid as the medium, like a battery, and the precipitates will end up in your loop, most likely as a sludge.

But...if it honestly gives 3x performance, I might look at it. I'm not sold that round tubes are better than flat for heat dissipation, though, unless they are inducing turbulence. Laminar flow would have the water on the edges cooled, while the water flowing in the middle of the tube remains uncooled. With flat tubes, that uncooled portion is small, while with round tubes, it is much bigger. By adding turbulence, you force the water away from laminar flow and more water meets the edges. To do this, though, you have to introduce impingement, which means you need more head pressure from your pump, which dumps more heat into the loop.

It will be interesting to see some real test data for this new product. And we won't know any real-world results from galvanic corrosion testing until it's been in use for a while. Age-testing on a product this new...yep, hate to be the consumer who does this for the company. But, if the corrosion is very slow, then flushing your loop every six months might be enough to save it, along with inhibitors. We'll see.

With stainless, my understanding is that it isn't the steel that you have to worry about (since it is plated from the manufacturer) but rather with the welds and the filler metal being used for them. If you use a lesser quality metal than stainless wire for welding (or soldering as traditional radiators are constructed) then yes, you could potentially run into issues.

However, it remains to be seen exactly how they are constructed and of what materials in the joints. Stainless steel is used in surgical instruments and other high-quality components all over the world for good reason: non-reactivity to most common corrosives.

Since galvanic corrosion has been a major concern in watercooling loops for years, I highly doubt that a company like Feser would fail to incorporate safeguards to prevent this.

As for the internal design and the flat vs. round tubes, that also remains to be seen as to the end result and design. You could implement a golf-ball 'dimple' design and increase surface area dramatically and allow increased coolant flow INSIDE the tubing while allowing minimal airflow OUTSIDE with the proposed fin designs. Again, until we see some reviews, tear-downs and real world data, it's all speculation.

The pics that ARE out seem to portray it almost as double-thick rad. Again...very, VERY curious as to how these perform.

Yeah, these are the 3x120 or the 3x140s...I know they are making a 5x140...

Had a long talk with a doctorate chemist, and his opinion about the galvanic corrosion is such that, yes, it will occur, but it would take about 10 years before you saw anything since the metals do not have a great affinity to each other. Depending on the SS alloy, it could be either the cathode or the anode. Either way, the reaction is so slow that it can be countered by inhibitors and flushing your loop at least once a year without any real damage.

Still waiting to see some actual testing data. That would be most telling whether it is good for the money.

^Is that a dual 80mm?

Oh, the old days...I think I have a couple 1x80mm rads around in a box somewhere from my very first Swiftech kit. :)

Hope it works for you; I'm not familiar with that line of rads. I'm holding out on the Admirals, myself...I'd like to use 1 to replace the dual MCR320's i'm running now...thinking the 4x140 Admiral might be able to accomplish that task...we'll see.
