I have rather old notebook IBM T23 - PIII 1.13 GHz for web/e-mais/IM @ winXP.
It is really hot at the bottom. There are 2 hot spots: the CPU area and HDD area. I can force CPU to run 733Mhz max so I can lower cpu heat, but the HDD area is about 45-50 'C hot., which is really unplesant with notebook sitting on your laps.
So I want to replace my notebook HDD with a new one, hoping that the new one will be quieter an cooler (i can use replaced HDD in my home server and make it server system HDD).
I found MikeC post
"Even slow 4200rpm drives weren't that quiet as recently as 2.5 years ago (the age of the last notebook I bought). But there's been a transformation in notebook drives over the past year or two, and they are quieter and faster than ever."
Because my notebook HDD surely fits in "before transformation in notebook drives"
category - replacing it coud make a real difference.
I've checked recommended section, (http://www.silentpcreview.com/Sections+index-req-printpage-artid-29.html
) and I think I have to choose between 4200RPM/8mb Toshiba MK4025GAS and 5400RPM/8mb Samsung MP0402H 40G.
Samsung seems to be a better choice... for a silent desktop with HDD suspension.
But I think that for hard mounted notebook HDD the better choice is Toshiba, since it is slower 4200RPM drive -> possily quieter and little cooler then 5400RPM Samsung. The downside is that i will take little preformance hit (compared to Samsung) but it will be still faster than my old drive (i hope).
I'm planning to add 512MB memory stick (i have 256mb now) and turn swap file off and maybe make ram disk for Firefox browser cache. It will also limit access to hdd and help a little bit in cool/quiet department
