Overclocking, Heat & Power
We approached overclocking these cards with some caution because of what we mentioned before about heat issues. Since faster clock speeds equal higher temperatures on the GPU, more heat dissipation is needed, which can be a problem for cards with fan-less heat sinks. We found that the 7600 GS Silent did actually have trouble with overclocking, but interestingly, the Silent 7800 GT managed to achieve quite a high core and memory clock. Here are the clock speeds we achieved.| Overclocking Results | ||
| Core Clock | Memory Clock | |
| ASUS EN7800 GT TOP Silent | ||
| Default | 420 | 1240 |
| Overclocked | 481 | 1290 |
| % Increase | 14.5% | 4.0% |
| ASUS EN7600 GS Silent | ||
| Default | 400 | 800 |
| Overclocked | 442 | 874 |
| % Increase | 10.5% | 9.3% |
We tested these clock speeds by running the Splinter Cell Chaos Theory benchmark stress tests to verify stability. One thing to note is that these cards tended to get incredibly hot to the touch after several minutes of testing. Here are the performance results in Splinter Cell of the overclocked cards.
There's not much difference at all between the factory and user overclocked silent 7600 GS. This card was the worst of the two at overclocking and had a lot of trouble running stable (i.e. without graphical artifacts) during our stress tests. However, once we established the overclock of 442MHz/874MHz, the artifacts left and our tests ran cleanly. With the silent 7800 GT, the difference our overclocking makes is fairly significant. It did manage to boost performance by several fps, which may be a noticeable improvement during gameplay.
Power Consumption
We also tested the power consumption of these cards to see how much power they drew and if there was anything out of the ordinary. We acquired our power numbers by measuring the wattage of the total system at the wall outlet while idle and under load (stress tests). These are the results we recorded.
As expected, the EN7600 GS Silent drew much less power than the EN7800 GT TOP Silent. Neither of these cards are really power-hungry, but the fact that the EN7800 GT TOP Silent requires a 6 pin power connection reflects that its consumption is on par more with other cards of this type. The EN7600 GS Silent requires no external power connection, and its consumption is fairly low, which is good for those concerned with power draw.
Heat
We tested the temperatures of these cards as well to get a good idea of their heat levels generated during operation. We acquired the results here similarly to the power test, by taking the temperature of the GPU (in Celsius) while the system was idle and under stress testing. Here are the results.
As we mentioned above, both cards do get very hot to the touch after running any 3D application for a bit. Something interesting here is that the EN7800 GT TOP Silent runs cooler at idle than the smaller EN7600 GS Silent. At load however, the 7800 GT gets about 5 degrees C hotter than the 7600 GS. The EN7800GT cooler is obviously larger and better at dissipating heat, yet the card still gets hotter because it is a much more powerful part.

The ASUS EN7600 GS has both 256MB and 512MB versions currently available on Newegg. What version was included in this article and how big a performance difference could we expect between the two? Thanks.SciBoy - Monday, July 24, 2006 - link
Could you list the memory sizes of these cards, please? I have the 7600GS but with 512Mb, and I'm pretty sure there is a 256Mb version too. They're claiming the 512Mb version is faster, but I'm starting to feel bad about my purchase today (considering that the 6600GT, which was my old card) seems to even be faster in some instances (especially considering I paid the equivalent of $170 for the 7600GS and I could buy a new 6600GT for $90, albeit with only 128Mb mem).A compounding factor is that I had the Gigabyte silent 7800GT but had to return it when dual mode did not work on it (some kind of problem the Gigabyte 7800GT apparently has, I can't recommend it to anyone).
Well, anyway, mem sizes please! :)
Thanks!

heyjust a suggestion
if there could be a page with a listing of a plethora of cards and their relative performance versus each other so it can be easily seen if its worth upgrading to a newer generation
eg. someone has a 9800 pro; is a 7300gs faster? (ignore the obvious agp/pci-e fact)
or a x800gt vs a 7600gt?
its hard to look over your old articles to compare as some dont use the same benchies/resolutions/etc..
it doesnt have to be super accurate, only accurate enough to say card X is generally better than card Y
inclusion of high end older cards (5900, 9800, x800,6800 etc.) are important
as well as mainstream generational cards (6600,9600xt, -- god forbid 9200,6200 :)
thanks

Tom's Hardware does this. It's a series of major roundups called "VGA Charts", IIRC.For current-gen cards, there's Digit-life's video digests.

i wonder if these fit in X-QPack uATX cases.. any owners out there?poohbear - Friday, May 12, 2006 - link
if u could provide sys or case temps that'd be great so we can know what to expect in our own rig (my rig runs about 34c in the summer:o). really impressed @ how these babies perform considering they're so quiet, but as someone mentioned, the accelero x1 is indeed virtually silent albeit cools much better than the stock aircoolers.Cerb - Friday, May 12, 2006 - link
No fan = silent. 'Virtually silent' is marketting. Ambient noise may cover up a certain degree of noise (ideally all noise from the computer), but every fan gives a greater chance of it being audible, or worse (such as a VGA Silencer): grating and annoying, even when not terribly loud.nullpointerus - Saturday, May 13, 2006 - link
"Virtually silent" is not marketing. If you have trouble with it - such as in a home theater setup - it's better to use extension cables to position the sound further away (such as behind a corner or a piece of furniture) than to embed an ~80C heat source in the computer.As for my VGA Silencer, I can't hear it. My computer is under my desk, not on top of it. I have two low RPM 120mm fans in my ~$60 case and even when my CPU is overclocked and at full load the variable speed CPU fan barely goes above 1200 RPM while staying under 50C. That's pretty cool, IMHO.
IIRC, there were some VGA Silencers shipped out with bad fans. You might want to try getting a replacement if yours grates. Good fans do not grate. And if you are referring to the tons of junk out there that are misrepresented as "virtually silent," then I feel sorry for you. I bought a few such fans, and they sound like jet engines...

With Turions, Pentium-Ms, and newer A64s, etc., it shouldn't be too hard.
"My computer is under my desk, not on top of it."
Same.
"CPU fan barely goes above 1200 RPM while staying under 50C."
Mine are all well under that (fastest is the Panaflo, ~700 RPM). I don't think I can get a diode reading, so won't trust what I have to be definitive (socket reading stays below 50, but Thermaltake's Orbs ruined any confidence in that--twice).
"IIRC, there were some VGA Silencers shipped out with bad fans."
No, it's from the design and materials. Not quite as loud as a standard A64 stock cooler, but annoying, and stays annoying even slowed down. The fan being part of the duct, and duct being brittle plastic are mainly to blame. Attaching another fan, even somewhat decoupled (1/2" of foam mouse pad), causes the same kind of noise, though far less pronounced. If softer plastic were used (which would likely not be clear), I don't think it would be bad at all.

Assuming they all use the same fan (mine is a NV Silencer 3), it should be a bit louder (I was running it at 5v until yesterday) than everything else I use, with my CPU fan being the only one close. See the note here for my primary issue with the VGA Silencer's noise (the entire thing is a fan frame): http://www.silentpcreview.com/article63-page2.html">http://www.silentpcreview.com/article63-page2.html
"and they sound like jet engines..."
No jet engines in sheep skin (but, I did start with them, ugh!):
Nexus 120mm (5v, might be removed soon, or upgraded to CPU fan duty)
Yate Loon 120mm from Fortron PSU (5v, soon to be replaced, being near as loud as the Silencer, if easier to listen to)
Panaflo L1A 80mm (5v, now in place of NV Silencer)
Adda 120mm in Seasonic S12 380 (I may try to isolate it a bit, if I get bored enough one day)
Either the entire system is inaudible (listening position and distance counts, as does ambient noise), or it can be heard. "Virtually silent" is a good way of saying, "it's not loud." But there is quite a gulf between "virtually silent," and, "is it really on?" If you're after "is it really on?", Gigabyte and Asus offer the only stock gaming cards worth considering, because it means no voiding the warranty--such a cooler as the X1 is not a good option (I should have considered a Geforce FX not an option *grumble*).

You could always try getting a 7900 GTX and underclocking it. :) The big fans and HSF should do a good job at keeping the card cool if you drop clock speeds a bit. I'm not sure how well the RPM controls work on the cards, though.
