11. A Different Approach – Familiar Grouping

12. Current Media Center PC Noise Levels Measured using ISO Standard 7779: 1st microphone is placed 50 cms above box and 2nd microphone is placed 50 cms in front of box and 120cms above ground at angle of 45 degrees MC PC 1MC PC 2MC PC 3 Ambient Reading 40 dB33 dB36 dB

13. Current Media Center PC Noise Levels Comparative noise levels Traffic 60 – 70 dB Quiet urban night 40 dB Whisper 25 dB A human can distinguish a change of 3 dB MC PC 1MC PC 2MC PC 3 Ambient Reading 40 dB33 dB36 dB

14. CPU Coolers Big and slow is better than fast and noisy Passively cooled is even better (how about 0 dB?) Designing a Quieter PC Power Supply Units Temperature controlled work best Speed increases as temperature rises Spend the effort to find quiet fans

15. Current Media Center PC Heat Levels Measured using thermistors placed on major components plus inside and outside of case. Measured at idle and while recording two TV shows plus playing a DVD. MC PC 1MC PC 2MC PC 3 Internal Temperature 34.4 C40 C37.6 C

16. Designing a Cooler PC Choose a CPU with low power consumption See popular review web sites Take advantage of demand based speed and power technology Bundle software that make sit easy for the end user CPU cooling technology has come a long way

17. Designing a Cooler PC Now we need to focus on other components

18. It’s All About Air Flow Do Leave plenty of space around hard disk drive Direct air flow at the hard drive Direct air flow across gpu and tuner cards Use extra case fans

19. It’s All About Air Flow Don't Block airways with cables Stack graphics and tuner cards too close together HDDTunerGPU Temperature w/ indirect airflow 56 C62 C64 C Temperature w/ direct airflow 50 C57 C59 C

20. Call To Action Maximize your customers’ living room experience by designing PCs with More powerful feature sets High definition video Compelling price points Attractive form factors Consumer friendly back panels No noise Passively cooled components

21. NVIDIA Solutions for a Cool and Quiet PC GeForce 6600 Passive High Definition PureVideo NForce chipsets nTune software automatically adjusts settings to find coolest quietest operation of CPU, GPU,MCP, RAM, Voltage and Fans Hardware firewall offloads CPU for media-centric tasks NVTV Better TV than your television
