Its a fact of life for i8600 owners. The hard drive sits directly under that palmrest and there is really noting that you can do to stop it generating heat. In any case, it shouldn't get anything more than warm, I have the 7k60 in mine and its just barely warm after hours of use.
I know. Originally in my i8500 I had a 60GB 4200rpm, and it got temps up to and exceeding 50C as well. As soon as I changed to the 7k60 in my i8500 I noticed the speed, quietness and coolness of it.
So of course when ordering my i8600 there was no question, I had to get the 7k60 with it.
Other 5400rpm drives may actually regularly exceed 50C, new technology has helped the 7k60 stay very cool considering its rotational speed.
well i have the 40 gb 4200 RPM and most of the time it goes up to 43c. the hottes thing in my laptop is my ATI 9600. is this normal i see it and is always about 50C+. right now is at 55C and im just surfin.
