NVIDIA's GeForce GT 430: The Next HTPC King?
by Ryan Smith & Ganesh T S on October 11, 2010 9:00 AM ESTPower, Temperature, & Noise
We only have 1 GT 430 card on hand, so unlike past articles we cannot compile any data on the load voltages of this line of cards. Our lone Asus card has a load voltage of 1.08v, and an idle voltage of 0.88v. Idle clocks are 50.6MHz for the core, and 270MHz effective for the memory.
While GT 430 may not be competitive on a performance-per-dollar basis, it’s hard to argue with these power results. Even at these low wattages where our 1200W power supply isn’t very efficient, the GT 430 still delivers an idle power consumption level 7W under the Radeon 5570, and an even larger 11W advantage over the otherwise performance-superior Radeon 5670. We can’t measure the card’s actual power consumption and NVIDIA does not provide a reference level, but the GT 430 can’t be drawing more than a couple of watts here.
Under load things are less rosy for the GT 430. Under Crysis it ends up drawing 10W over the 5570, which serves as yet another testament to the amazing level of performance-per-watt that AMD has been able to attain; remember that the 5570 had better performance at the same time. Under Furmark the situation is just as bad, but at this point we’re looking at a more pathological case. Overall 10W isn’t going to break the bank in an HTPC (especially since these cards would rarely get up to full clocks in the first place) but it’s something to consider if every watt is going to count.
When it comes to idle temperatures, the GT 430 is second to none. With the card only consuming a couple of watts at idle in the first place, its idle temperatures are barely above room temperature (and even closer to ambient case temperatures). It’s tied with the GTS 450, which impressed us last month with its highly capable cooler. Meanwhile our 5570, which is a low-profile card just like the GT 430, ends up being a good 10C higher. AMD’s higher idle power consumption directly translates to a higher idle temperature.
Looking at load temperatures, these results aren’t all that surprising given the cooler in use. The Asus cooler is practically a passive cooler, as the small fan is not capable of moving much air (though it is unusual to not see Asus aggressive on cooling). As a result it manages to reach higher temperatures, but we’re still only talking about 60C under Crysis and 72C under Furmark. This is worse than the 5570 and its larger fan by a bit, but not significantly so.
At idle the GT 430 is consistent with our other cards. With the exception of a couple ridiculous cards like our GT 240 and in this case the 5570, everything is at roughly 42-44dB(A). The 5570 is more fan than heatsink, which is likely why it has such a poor showing here compared to the GT 430.
The payoff of accepting higher temperatures is less noise to contend with. The GT 430 never needs to ramp up its fan in our tests, delivering a load noise level even lower than the GTS 450, and only worse than a GT 220 that runs up against ambient noise levels. If you want to make a good HTPC card then it needs to be silent, and Asus/NVIDIA have delivered on that here. It’s not quite silent since it’s not passive, but it’s about as close as one can reasonably achieve. It’s also noticeably better than the 5570, a card which is by no means noisy. If noise is a primary concern then the GT 430 is a very good candidate for a HTPC.

BTW, I've only had problems with one card. A nvidia 6600 GT or something.....The fan burnt out, and the card starting getting real hot. You can guess the rest. It was getting old though.dnd728 - Wednesday, October 13, 2010 - link
With fresh new Windows 7 install it would for example never wake up right from sleep - it may permanently freeze or refuse to log in or log in keeping the log-in screen and stop responding, artifacts may also show up.In XP none of that happens, but frequently and sporadically the VPU would crash and get restarted. No need stressing the GPU or CPU at all. It would also break the anti-keylogging software. Get the card out, and everything is back to normal.

Never had these issues with my 5970 on win 7.khimera2000 - Thursday, October 14, 2010 - link
sorry 5870 not 5970.dnd728 - Thursday, October 14, 2010 - link
Well, obviously they're working for most people.The question was, why so many people buy nvidia, and I gave one reason, my personal one - not because I love nvidia, but because the comparable AMD does not work for me. Give me any third competitor, and I'll give them a try. :)

If you are constantly crashing windows, (blue screens), then you have bad hardware whatever is broken it needs to be replaced.dnd728 - Tuesday, October 12, 2010 - link
True, that's how I know it's ATI/AMD.extide - Tuesday, October 12, 2010 - link
It's not ATI/AMD, you may have happened to have a bunch of bad AMD/ATI cards yourself that were bad (in which case you would be extremely un-lucky and I actually highly doubt that is the case), but they in general are NOT. I have ran both, and even 3dfx back in the day. Currently my box at work uses a 4350, 100% stable (4Ghz i7/X58), never blue screens, and my pc at home has had MANY configs (single 4850, dual 4850, single 4870, single 4350, etc) NONE of them caused stability problems, and I have ran many many many driver versions over time . I am not insulting you or your intelligence but I am saying if you are getting blue screens in windows these days you have bad hardware or a bad driver. The ATI driver is not bad/broken, period.I'm not even a fanboy I have owned products from both vendors and my next may be an ATI/AMD one or an nVidia one, I haven't decided yet and I dont really consider stability to be a part of the decision as neither one of these companies make straight up un-reliable stuff. Infact last card I had was an 8800GT and then before that was an ATIX1950Pro in crossfire, and prior was just a single X1950Pro, and prior was a gf4 ti4200, then prior was a gf3 ti200, then prior was a voodoo 5 5500, and prior was a voodoo 3 3500, and I had many card before that too. That's just my main machine....
There IS something bad in your machine, don;t take it as an insult, be mature about it and just figure it out dude.
I remember years ago I was working on a machine that used RAMBUS, and I dont know if you are familiar with those but they required terminators in un-used ram slots. It had stability issues, I tried everything eventually pretty much swapped out all the hardware. It ended up being bad terminators in the empty ram slots. Weird stuff can and does happen with computers.

Sorry, the 4Ghz i7/X58/6GB is my main pc at home, and my box at work is a Q9400/Q45/8GBdnd728 - Wednesday, October 13, 2010 - link
All of my machines plus a few others being defective in a way that would not allow them to accept ATI, but only competing brands? That's even less likely.If your car keeps breaking while driving road x, and nowhere else, then at first you say - a coincidence, then you look for a reason and decide - bad luck, but eventually you just avoid that road. Even if many other drivers are happy with it. It's not worth it.
