[KAOZ23]

Raspberry pi B+
Aluminium heat disipators
Acrylic enclosure
5V 20x20 fan, running at 3.3V (for noise)
Openelec 4.97.2
Pi is powered via USB port from a Memup ZX HD Multimedia HDD (one port for power, other one as storage)


My configuration file:
gpu_mem=128
gpu_mem_256=128
gpu_mem_512=256
arm_freq=1100
core_freq=550
sdram_freq=600
force_turbo=0
initial_turbo=0
overscan_scale=0
disable_overscan=1
overscan_left=0
overscan_right=0
overscan_top=0
overscan_bottom=0
hdmi_force_hotplug=1
hdmi_ignore_cec_init=1
hdmi_drive=2
hdmi_force_edid_audio=0
hdmi_pixel_encoding=0
hdmi_ignore_hotplug=0
sdtv_mode=2
sdtv_aspect=1
hdmi_ignore_cec=1
disable_splash=1
over_voltage_sdram=4
max_usb_current=0
over_voltage=8

With this configuration, playing full hd files:
Max temperature is 38,5ºC (more or less).
On skin (confluence), 34ºC.
Room temperature is about 21ºC, but pi is inside a furniture, so maybe is more.

Before those new parameters I use Turbo, and temperature was 31ºC at iddle and 34ºC playing full HD

The confluence skin is noticeably more responsive, and also, other skins now go faster. Now I can use a keyboard arrows without delay.
Very happy with these settings
