Samsung HD160JJ temperatures

[Matas]

I have just purchased Samsung HD160JJ hard drive. I installed HD Tune program to see temperatures of hard drive. The program shows that temperatures are strangly jumping.For example: from 36C to 40C(not rising 36C-37C-38C-39C-40C), but jumps from 36C to 40C. Is it normal?

HD Tune doesn't have sampling interval, but I tried HDD Thermometer, where interval is 1second. The same situation(from 36C to 40C).

So, any ideas?

Can it be that the serial ata drivers from MB floppy are a bit buggy and causes this nonsense with temperature?
