Thank you, a great review of a great product for the silence hungry gaming crowd.
I'd also like to draw attention to Asus' 670 GTX offerings that have a just as low noise and efficient cooling solution. For some reason it isn't mentioned in the price discussion where Radeon HD 7970 is mentioned, but the ASUS GeForce GTX 670 Direct CU II TOP edition is almost as fast as the 680 GTX (reference clock) at a much better price!Thanks for the review. From the pics, I understand why the VRM temps get excessive at the reduced fan speed. The environment has to blow through the gpu heatsink first before it hits the VRM heatsink. Plenty of resistance. I have to Belstaff Canada
think another designs that use thermal tape between the VRM and the backplate of the main heatsink would be better for lower rpm cooling (plus providing some cooling for that RAM). On the other hand, I was surprised the 112C temp only decreased the efficiency with a watt (figuring the GPU VRM is where most of the loss is).
Kudos to Nvidia for their low idle/2D and 2D multimonitor power use on Kepler.
errata: page 3, Estimating DC Power The Kingwin PSU table has the Seasonic label (but has the correct Kingwin data).
Just to make sure is 840 RPM on both fans the lowest the card selected itself, or will it be the lowest you could force manually?
To not derail the thread, but tend to some owners of similar Asus cards Woolrich Parka
(670, 660 Ti) share their fan speeds? A minimum of just for idle? These two latter cards have 2slot coolers there may be some differences in performance under Parajumpers Sale
load, however i guess in idle each one of these should behave similarly and thus should their fans. Come to think of it, the fans on 670 and 660 Ti Asus look slightly smaller, could be they're not 100 mm across?
Would also love to see 660 Ti tested, especially Asus and GB Windfart versions. Both look v promising for noise conscious users. It is also a plain fact that SPCR works with the material and resources they have; Moncler Outlet Uk
if you, on the other hand, have an extra $150, I'm sure the 660 Ti review can be arranged.
It is good to see the DirectCU cooling system get an SPCR Parajumpers Sale Uk
level review, even though it is only one the beefiest iteration, and Asus hasn't seen fit to designate the different versions, just the "generation", which feels a lot more like marketing than anything else. I refer to it as Buy Ugg Boots Uk
serendipity two reviews from one delivered product.
Used to do realize this. Either way other reviews puts the GTX660TI underneath the GTX680 so i will probably just buy that version.
Thanks to SPCR i now feel safe buying the DCUII versions of GTX660TI or GTX670.

Ah. I have been tracking GTX 660 Ti reviews here. Take a look at the HT4U review of the Asus card. You are able to compare it's performance vs the GTX 670. Not quite the TDP of the 680, but you can see the delta.
Yes actually did see that review in that specific thread and i was amazed. A lot of the instances when sites have dbA or SpL of 30 as quiet im very sceptical Uggs Canada
therefore it was nice to see the GTX 660Ti is actually very quiet considering they measure it at approximately Ugg Canada
1618dbA at gaming or full load. The fact that they have the GTX670 at 30dbA att full load means the accurucy within their equipment must be high.
Recently i upgraded to this card from MSi GTX570 Twin Frozr II which card by comparison is VERY noisy. There's a some kind of midfrequency bearing noise that is transmitted directly into my computer case and it has made my system significantly more noisy.
I was originally going to buy the 670 DirectCU Overclock but my preorder fell through it seems the 670 will be a much better card for silent computing. At this point I think I will need to look into an aftermarket cooler when i can clearly hear my computer from over the room.

I recently installed another GTX 660 Ti in very quiet test system (15 to 19dB inside). Unfortunately, when I added a second GTX 660 Ti, some new supply of noise kicked up. I thought it was the second video card but it turned out to be the motherboard. A faint high pitched EMF tone starts up when running in SLI mode. Basically remove a card, the system is silent.
To further test the problem, I installed a single ZOTAC GTX 680 and ASUS GTX 680 DirectCU II which come up with same noise. I swapped the card out with a GIGABYTE GTX 670 OC and also the EMF tone is less prevalent. Which has me wondering if its your card, or the motherboard.
