SS50 barebone has embedded in its Bios a revolutionary 3 phase Variable Fan Speed and CPU temperature Control feature, for use in conjunction with Shuttle I.C.E. heat-pipe technology especially designed for SS50 barebone. This feature is controlled via Bios, in which the CPU fan rotational speed sensing/control is governed by CPU temperature setting pre-selected in Bios.

By Bios factory default, "CPU Fan Auto Guardian" feature under  PC Health Status is enabled. Shuttle SS50 barebone factory  default for CPU heat-pipe fan cooler is set to Fan 3 as shown on  the right diagram. Prior manually modifying the CPU fan settings,  please make sure both fan connectors are plug into the correct fan  connector designations on the mainboard.

The "Fan Speed Up When CPU Temp" feature ranges from 40°C to 52°C, in an increment of 4°C. The bios default temperature is at 48°C. 1st and 2nd phase Variable Fan Speed and CPU temperature Control is as defined by "Fan Speed Up When CPU Temp". For example, if preset this setting to 48°C in bios and when actual CPU temp (reported by Bios) stays below 48°C then CPU fan speed will run at a quiet mode (1st phase) of approximately 2200 RPM.
But when the actual CPU temp goes above the pre-selected 48°C temperature threshold, then CPU fan speed will automatically engage into normal mode (2nd phase) of about 3000 RPM. Automated by the Smart Bios feature, this increase of fan rotation speed will effectively cool down the CPU temperature. And when the CPU temperature drops back below the 48°C temperature threshold, CPU fan speed will again automatically drop back to the quiet mode (1st phase) of about 2200 RPM in order to reduce fan noise level.
Fail-safe mode (3rd phase) Variable Fan Speed and CPU temperature Control is as predefined at 56°C. Where in the event of system and CPU operating under extreme working conditions, and if CPU temperature is raised above 56°C then the Smart Bios will engage the CPU fan in Fail-safe mode to rotate at about 3300 RPM. Please note that the higher the fan speed, the fan cooler will be become slightly noisier in order to compensate for the increase in CPU temperature.

3 Phase Fan Speed	Fan Speed	Event
1st Phased	2200 RPM	Pre-selected Temp in Bios (48°C)
2nd Phase	3000 RPM	Pre-selected Temp in Bios (48°C)
3rd Phase	3300 RPM	Fail-safe Temp (56°C)

When "CPU Fan Auto Guardian" feature is "Disabled", CPU fan will run at its default speed of approximately 3300 RPM.
We strongly recommend if you wish to use other brands fan cooler please disable "CPU Fan Auto Guardian" feature, allowing the CPU fan to run at its default speed. We only recommend for CPU Fan Auto Guardian feature enabled with enclosed fan cooler from Shuttle.

 

Adhesive thermal silicone gel such as Shin-Etsu Silicone will set after about 6 hours and form a strong bond between the heatsink and CPU die or other applied surfaces (eg. memory module, chipsets). This type of adhesive thermal compound is strongly not recommended to use on P4 Socket 423/478 CPU die. Since fan heatsink will stick strongly to the P4 CPU die and due to P4 Socket 423/478 ZIF socket structural design, upon removal of the heatsink will force P4 CPU to break apart from the ZIF socket thus damaging both pins on P4 CPU and ZIF socket. Please use non-adhesive thermal compound for P4 CPU only to avoid any damage done to the ZIF socket and P4 CPU.

 

SS50 barebone features onboard SiS301 TV-Out chipset. The maximum input active resolution at PAL and NTSC system is 800x600. Because of the flexible scaling hardware, the over/under-scan (Active TV lines) modes supported by SiS301 are far beyond of these listed data below.

System	Input (Active) resolution	Active TV Lines	Over/Under Scan
NTSC	320x200	480 ~ 400	+
	640x480	480 ~ 400	+
	720x480	480 ~ 400	+
	720x400	480 ~ 400	+
	800x600	480 ~ 420	+
PAL	320x200	540 ~ 500	+
	640x480	540 ~ 500	+
	720x400	540 ~ 500	+
	720x576	576 ~ 510	+
	800x600	600 ~ 510	+

 

When using TV-Out function, the resolution shown on TV screen is either unclear or kind of fuzzy compared to that of fine resolution shown on regular CRT monitor. Why?
The observed output resolution lies in design and feature differences between TV and CRT monitor.
1. In general, a 17" CRT monitor with 0.27mm dot pitch  for crystal clear images, but TV only has horizontal line distance-to-distance.
2. CRT monitor supports high resolution output & refresh rate. But on the other hand, TV only has low scan line.
3. CRT monitor and TVs' Video's amplify specification is different. 

 

Please select 2 speakers output mode from C-media audio utility, then enable “S/PDIF Playback” for SPDIF out function to work.

Please follow these procedures to install PCI VGA card : 
1. Install the PCI video card on SS50, connect display device to PCI VGA card, then start the system.
2. Disabled the "Onchip VGA " at the Cmos Setup Utility, then save & exit.

What is the difference in Bios setting for Video Out between UTV and OTV?

SS50 has UTV and OTV function, default is UTV/NTSC, its stands for underscan and overscan of TVout. As you know, when enabling TV Out, the picture will not always fill the TV screen. The reason for that is that we use "underscan" if TV Out is enabled in order to make sure that all buttons, especially the ones in the corners of the screen, are fully visible. But the image out is not in full screen mode on TV. UTV is ideal for PC based environment.
There is a bios switch which enables an "overscan" mode for TV Out. This overscan mode results in absolutely no visible border on the TV. The picture coming from the PC will be larger than the picture displayed on TV. OTV is ideal for pure TV-out environment such as Karaoke entertainment or road show demonstrations.
There are some IMPORTANT points you should note:
- Some buttons (close, minimize etc.) may not be accessible if the application is in full screen mode (OTV), they are outside the visible range of the picture.
- Your PC Monitor will most likely switch OFF, because it can not support overscan (some monitor may be switched off automatically)
- The TV Out picture can NOT be adjusted, you can not use overscan and then downsize the picture so that it exactly fits the screen.
