High temperature caution! but the heat sink is cold.

I am still without thermal paste and without problems.

Perfect .

A mechanical and electrical engineer might tell you that you are either extremely lucky (and the two surfaces match perfectly) or you are compensating the lost efficiency of the thermal exchange with (unneeded) increased ventilation (i.e. fan spins more and faster than it could be enough).

I will only invoke Dhukat :

Much is written about the importance of applying thermal paste.
The last computer I bought new was in 2000 year, a IBM Net Vista A-20 (Pentium III)
From factory it came without contact paste.
In practice I don't usually put thermal paste on any computer that will support a possible faster processor change in the future.
In tests I have only noticed a maximum increase of 3º centigrade with or without pasta.
I do not know if any part of the processor will suffer from my unconsciousness.
poor thing, I am very sorry!

Running a year 2000+ cpu without thermal paste is asking for trouble. That 2 or 3 dollars/euros that you save on a small cheap tube might cost you a new system. Even if the cpu doesn't thermal throttle, the huge spikes in temperature from idle to load might kill the chip. Also remember that older cpu's are NOT designed to run hot like today's cpus.
