Does low temperature improve performance with normal clock..

Keeping the CPU in its specified temperature range will not improve
performance, but letting it get above its operating range will cause
the CPU to become unstable or even fail.

The cooler you can get your CPU the better, but to get a
temperature-based speed boost requires superconductivity, which
requires cryogenic cooling to achieve very low temperatures (typically
measured in units Kelvin).

I am not aware of any practical cryo coolers for PCs. They would be
very expensive and somewhat bulky. Maybe someone can adapt the
cryogenic coolers used in 1st- and 2nd-gen FLIR systems.

No, and no.
Keeping a CPU in its specified temperature range does improve performance;
fewer errors.
An Intel Pentium MMX or latter CPU will not fail from overheating; it will
lock up and cool down long before a damaging temperature is reached.
An important tool in overclocking CPUs the trade-off operating temperature
margin for clock speed margin. Typically, operating at a CPU core
temperature of 40 C can provide an significant increase in CPU clock speed
and stable operation that would not be possible with the same CPU with a
core temperature of 60 C.

" ... but to get a temperature-based speed boost requires
superconductivity..."
No, and no.

Superconductivity not only is NOT required, but would prevent operation of
the CPU.
Cooling to 40 C rather than 50 C usually will allow additional overclocking.

"... Maybe someone can adapt the cryogenic coolers used in 1st-and 2nd-gen
FLIR systems.
No.

The medium wave IR sensors used in FLIR type applications (thermal imagers)
produce very little heat; the coolers for such sensors mainly remove
environmental heat (a typical Peltier cascade stack of six stages might pump
15 milliwatts of heat and keep the sensor at ~ 1 100 C in a FLIR [thermal
imager] application). In comparison current X86 CPU modules dissipate 60 to
120 Watts heat, 5000 to 10000 times as much.
