If you have more context or specifics about the KBC1126NU (like its supposed function or any related circuit), I could offer more targeted advice.

  • 8042-style Keyboard and Mouse Controller (KBC) with PS/2 ports.
  • Industry-standard Legacy I/O: Floppy Disk Controller (FDC), Parallel Port (ECP/EPP/SPP), Two UARTs (16550 compatible).
  • Environmental Monitoring: A/D converter for voltage/temperature monitoring.
  • Fan Control: PWM fan tachometer inputs and speed control outputs.
  • Hardware Monitoring (HWM): Voltage, temperature, fan speed.
  • GPIO pins with multiple functions.

warm

The KBC1126NU normally runs (40–60°C) but not painfully hot. If yours is too hot to touch (>70°C), check these three culprits:

Pin Alignment:

It is a high-density QFP package; use plenty of flux.

Why You need to download ComboFix
ComboFix is the Best Anti-Malware Tool in the market

Combofix is a free malware removal program, intended for advanced users. It is a last resort malware elimination tool for computers running Windows XP 32-bit, or Windows Vista, 7 and 8, 32-bit and 64-bit.

In order to run Combofix properly, it would be best to close all running programs, particularly security software. Therefore, if you have anti-spyware or anti-malware software installed, make sure you close them before starting Combofix. Launching Combofix is easy, you just need to double click on the Combofix.exe file, and the program will do everything by itself after that. A registry backup and a system restore point will be created, and the scan will begin. The scan can take a while to complete as it runs around 50 scans. Once the scan is completed, you will be informed.

If Combofix was unable to remove some malware or issues were encountered during the scan, you can check them in the log file created by the program. It will be placed in the same location as the Combofix.exe file.

Keep in mind that Combofix is not a program for beginner users, and should only be operated as a last resort. Once the program is launched, everything is done automatically, and there is no reversing what it does.
