We have changed our method of measuring noise levels. We have built a system inside a Lian Li chassis with no case fans and have used a fanless cooler on our CPU. We are using a heatpipe based passive power supply and an Intel SSD to keep noise levels to a minimum. The motherboard is also passively cooled. This gives us a build with completely passive cooling and it means we can measure noise of just the graphics card inside the system when we run looped 3dMark tests. Ambient noise in the room is around 20-25dBa. We measure from a distance of around 1 meter from the chassis and 4 foot from the ground to mirror a real world situation.
Why do this? Well this means we can eliminate secondary noise pollution in the test room and concentrate on only the video card. It also brings us slightly closer to industry standards, such as DIN 45635.
KitGuru noise guide
10dBA – Normal Breathing/Rustling Leaves
20-25dBA – Whisper
30dBA – High Quality Computer fan
40dBA – A Bubbling Brook, or a Refridgerator
50dBA – Normal Conversation
60dBA – Laughter
70dBA – Vacuum Cleaner or Hairdryer
80dBA – City Traffic or a Garbage Disposal
90dBA – Motorcycle or Lawnmower
100dBA – MP3 player at maximum output
110dBA – Orchestra
120dBA – Front row rock concert/Jet Engine
130dBA – Threshold of Pain
140dBA – Military Jet takeoff/Gunshot (close range)
160dBA – Instant Perforation of eardrum
This version of the card significantly outperforms the reference cooler, averaging only 32.5dBa when gaming. Fantastic results.
Wow that is an amazing looking card. if they could drop the price I think it would sell great for them, ive never seen a 580 peak at 60c in furmark
Wait a minute, are they seriously trying to charge £500 in the UK for a GTX580? thats only 60 less than a 590 !
This has to be voted as one of the prettiest video cards on the market. ever. Its what LL Cool J would have in his rap days.
Nice cooler, if they dropped the price by £100 it would be a great buy, not sure how they worked that out. its not worth £80 more than the Asus Direct CU II, regardless of gold fans.
That is a brilliant graphics card, and I like the PCB design, I wish nvidia had gotten it right with the 590, but maybe thats why partners are charging so much for 580, they know its much better really long term. ?
QUESTION TO THE REVIEWER:
The review says the Zotac GTX 580 AMP² is the model reviewed, and clearly lists 1.5GB…but the Zotac website lists the AMP² as having 3GB. So what model was really reviewed, please? The 3GB AMP²? Or the 1.5GB AMP?
Thanks in advance.
GPuz screen is right on page 2, is 3GB.
Thanks, Zardon, and thanks for the review. FYI page one needs correcting, it currently reads “ships with a 815mhz core clock, an increase from 772mhz on the reference card, and the 1536MB of GDDR5 memory is overclocked from 1002mhz to 1026mhz”
Thanks, sorry about that. fixed.
