Überclok Reactor: Balanced Performance

Power
We measure power consumption using a Kill-A-Watt device at the wall outlet. Idle indicates a measurement taken in Windows with no applications running. Max indicates the maximum power draw with the system fully loaded (running four instances of Prime95 and 3DMark06 simultaneously).
We can see that the Cooler Master power supply gives a lot of headroom for the current system configuration, which is a good thing.
Noise
We measured noise with a sound level meter, at distances of 24" and 48". The case fans and video cards dominate the noise produced. For reference, ambient noise was approximately 37.5 dB(A).
The Reactor does well here, scoring lower than two of the other high-end systems we've reviewed, even with the 200mm side case fan.
Temperature
We utilized CoreTemp 0.99.3 to measure CPU temperatures, which has incorporated the latest TjMax values for Intel processors. We loaded each core with Prime95 and ran Crysis in the background.
In our look at the Überclok Ion, that midrange system never climbed above 50C at full load. Here, we are almost at that point at idle, but this is a completely different class of system. We're satisfied with the load temperature and never experienced any stability problems whatsoever, but still find ourselves wondering what the Tuniq 120 could do….

I said it in the Ion review and I'll say it again, this pseudo heatpipe/water cooling thing is just plain junk. I'm sure something like the Tuniq or even cheaper standard heatsink/fan combo's would produce better results. The problem with this cooling system is there just isn't enough reserve liquid, or contact time with the fan-cooled area. Make one or the other larger and the performance should go up a bit, but I just think it's a gimmick for show, a bit of form over function if you will.And thank you Christopher for bringing up the PSU. Without checking Anand's old articles, have you guys reviewed this exact PSU system? I'd be very interested to see just how badly the efficiency is due to being 20-30% of rated output for the majority of the time. A 650w PSU would have been perfect for this system, allowing for further OC'ing or added components while keeping the total cost down and possibly greater efficiency of the PSU.

>>>A 650w PSU would have been perfect for this system, allowing for further OC'ing or added components while keeping the total cost down and possibly greater efficiency of the PSU<<<We always want to ship single card systems with the possibility of adding a second GPU later without upgrading the PSU. Offering the Reactor with a 650-Watt PSU and marketing it as ready to run a pair of HD 4870 X2 would get us assassinated in the reviews. We wish marketing issues never got in the way of efficient design, but that's the reality of retail.
The Corsair 1000-watt is not horrifically overpriced, and it sets minds at ease. It adds $50 to the cost over the Thermaltake Toughpower 650-Watt modular PSU we've used in the past.

>>>his pseudo heatpipe/water cooling thing is just plain junk.<<<I think you must have mistaken our CPU cooler for another product. The Xigmatek HDT-S1283 is an air cooler - very similar to the Tuniq Tower 120. There's no liquid involved. It performs almost as well at a lighter weight, which is crucial wehn you're shipping cross-country. The Ion you refer to also uses the same cooler.

Ok, well since I'm using the HDT-S1283 as well, I have to ask you guys, because I just could not figure it out. How did you apply the thermal compound? There just doesn't seem to be any perfect way, what with the heatpipes involved rather than the usual flat surface.Thanks

At idle, efficiency is likely to be very poor, but at load it should get very good efficiency. I'm not saying it's an exact match (because I'm sure it isn't), but as an example the http://www.anandtech.com/casecoolingpsus/showdoc.a...">Zalman 1000W is above 83% efficiency with 120VAC from a load of 200W to 800W, and above 80% from around 150W to 1100W. If we take a baseline 80%, at 195W from the outlet the system idles at 156W, and at medium load it will use over 200W (so above 83%). That's of course assuming this is a good PSU, which I have no reason to doubt -- nearly all of the 1000W PSUs come from one or two ODMs, and with higher margins they also tend to use good components.7Enigma - Friday, October 10, 2008 - link
I'm just saying with most computers spending the majority of their time at idle/near-idle, it doesn't make a lot of sense. And that's not even mentioning the hundreds of dollars you could save (though lower margins likely for the company) for the piece itself. The few that do FAH and other idle-cycle programs are probably not being used by the target consumer of this computer.7Enigma - Friday, October 10, 2008 - link
The closest reviewed product I could find was another Corsair 1000w but it has a slightly different model number (you reviewed back in April of this year). Here's the direct link to the picture showing the efficiency:http://images.anandtech.com/reviews/psu/2008/corsa...">http://images.anandtech.com/reviews/psu/2008/corsa...
Seems like around idle (where the computer will spend most of it's time) it's closer to 80% efficient, while under load it get's up to closer to 85%. Again the model numbers don't match up exactly, but the general trend should be pretty consistent (ie doing little it's pretty inefficient).

Sorry for the double post, I got an error page and thought the comment hadn't been submitted. Feel free to delete this and the previous duplicate post!Christoph Katzer - Saturday, October 11, 2008 - link
