In-CarPC's CQ50 and CQ50P series of fanless in-vehicle PCs offer a high level of performance in a compact fanless system, supporting 6th generation Intel Core i3 and i7 processors with up to 32 GB RAM.  The CQ50(P)'s compact chassis supports dual removable 2.5" drives with RAID, and the CQ50P series is our first PC to include Power over Ethernet (PoE), providing 4 PoE ports in total.  Numerous built-in options are available, including up to two 4G/LTE modems, GPS, Wi-Fi and CAN-bus.  The CQ50(P) can drive 3 displays independently via its DVI, DisplayPort and VGA video outputs.

The fanless nature of the CQ50(P) series makes it suitable for extremely dusty environments, and the device's ruggedness is demonstrated by multiple MIL-STD-810G tests.  The CQ50 series has been awarded E-mark certification (CQ50P pending), making it fully approved for in-vehicle use, and carries a 2-year warranty as standard.

Removable mounting flanges supplied

Vibration & Shock

MIL-STD-810G (with SSD)


Passive cooling (fanless)


Width: 250* mm
Depth: 150 mm
Height: 55* mm

*The above figures are without mounting flanges at base.  With mounting flanges, width increases to 270 mm and height increases to 62 mm. 


2.4 Kg (base specification)


Operating Temperature: -40°C to +70°C

Storage Temperature: -40°C to +80°C

The above temperature ranges are at base specification and with extended temperature RAM & SSD. Using standard RAM results in an operating temperature range of 0°C to +70°C. Using a standard SSD results in an operating temperature range of 0°C to +55°C. Some optional features also restrict the unit's operating temperature range - for the operating temperature range of a specific configuration please contact us.

In common with all passively cooled (fanless) computers, the PC should be installed in a location that allows cooling air to flow freely over the chassis fins. 

Power Consumption
  • Whilst idling at the Windows 10 desktop:
    • average over 30 seconds: 8.48W
  • Whilst loading the Windows 10 operating system (from completion of POST to appearance of desktop):

    • peak observed: 25.81W
  • ​Whilst under stress-test conditions:
    • average over test: 37.08W
    • peak observed: 47.02W

The above figures were measured with a base-spec CQ57 PC (i.e. CQ50 series with Core i7 processor, 4 GB RAM and 120 GB SSD).
