PCI Data Acquisition and Signal Processing Controller driver

DeviceInBox editorial team · Last updated September 17, 2026

"PCI Data Acquisition and Signal Processing Controller" appears under Other devices when Windows detects a device of that PCI class but has no driver to name it. The name sounds like a lab instrument, yet it almost never is one. On Intel laptops and desktops it is usually a thermal subsystem of the processor or chipset, the part that reports temperatures and lets the system control fan speed and CPU power limits.

Identify it by hardware ID

Right-click the device, choose Properties, open the Details tab and select "Hardware Ids". Compare the vendor and device codes (how to read them) with the list below. The usual suspects are:

  • PCI\VEN_8086&DEV_1903, DEV_1603 and similar IDs: the Intel Processor Thermal Subsystem on Skylake, Broadwell and later CPUs.
  • PCI\VEN_8086&DEV_A131, DEV_9D31 or DEV_A2B1: the Intel PCH Thermal Subsystem in the chipset.
  • PCI\VEN_8086&DEV_1D77 and other C600/X79 IDs: chipset functions on older Intel workstation boards.

DEV_1903 is the processor thermal subsystem, not a measurement card.

Chipset thermal devices: Intel Chipset Device Software

For PCH thermal devices and most other chipset functions, Intel Chipset Device Software is the fix. It adds the INF files that identify these devices, and the unknown entry is renamed to something like "Intel(R) 100 Series/C230 Series Chipset Family Thermal subsystem - A131".

Run the installer as administrator and restart.

Processor Thermal Subsystem: the thermal framework driver

The processor thermal device (DEV_1903, DEV_1603 and their newer counterparts) is used by Intel Dynamic Platform and Thermal Framework, which Intel later renamed Intel Dynamic Tuning Technology. Laptop makers tune it for each model, so the best source is the support page for your laptop, usually in the Chipset or Thermal section. Packages in our catalog:

A laptop without this driver still works, but it may run warmer, throttle earlier or keep the fan louder than it should.

Which package you need depends on which thermal device it is.

Devices from other vendors

On AMD systems, install the AMD chipset package for your platform:

If you really do have a measurement or capture card (National Instruments, Advantech and similar), install the software from the card's manufacturer. For anything else, search for the exact hardware ID:

Chipset devices that often turn up alongside it: SM Bus Controller, PCI Simple Communications Controller and Base System Device.
