Intel I7 920 on Asus P6T-SE motherboard, optimized to 3.99Ghz.
Today I chose to attempt overclocking my very old CPU for the first time.
I had never adjusted my CPU before, only my GPU.
I followed a guide I found on overclock3d.net.
I installed CPU-Z, Prime95, RealTemp, and MSI afterburner for monitoring and stress testing.
I updated my CPU in the BIOS.
My AI tweaker settings are as follows:
AI Overclock Tuner: Manual
Intel SpeedStep Tech: Disabled
CPU Ratio Setting: 21.0
BCLK Freq: 190
PCI-E Freq: 100
DRAM Freq: DDR3-1523Mhz
UCLK Freq: Auto
QPI Link Data Rate: Auto
CPU Voltage Control: Manual
CPU Voltage: 1.30000
CPU PLL Voltage: 1.90
QPI / DRAM Core Voltage: 1.25
IOH Voltage: 1.20
IOH PCI Voltage: 1.50
ICH Voltage: 1.30
ICH PCI Voltage: 1.50
DRAM Bus Voltage: 1.50 (cannot exceed this or I receive a warning)
DRAM DATA REF Voltage on CHA: 0.500
DRAM CTRL REF Voltage on CHA: 0.500
DRAM DATA REF Voltage on CHB: 0.500
DRAM CTRL REF Voltage on CHC: 0.500
Load Line Calibration: Auto

I have an Intel I7 920 with a stepping of 5, 3x 4GB RAM DDR3 Kingston at 1333Mhz.
My computer booted up, I ran a stress test with Prime for about two hours. The CPU reached 98°C, which is extremely high.
Eventually, I let it cool down and restarted with the same OC settings. After that, when I played a game, the lag disappeared. The CPU stayed around 70°C.
My CPU comes with a Coolermaster Hyper212 heatsink.
I live in an area where the temperature is usually between 30-34°C.
What could I be doing incorrectly? Why does my CPU reach such high temperatures?
Why does my game lag so much?
