Seagate 7200.3 160gb vs 320gb heat

I was wondering if there is a margin of difference between the heat given off by either of these drives. I undestand that the 160 is 1 platter, and the 320 is 2 platter, but is there any noticeable heat difference? Anything right now is good, laptop gets quite warm. I use a sheet of wood (1/2in thick, and has holes drilled in it) as a cooling pad, does its job better than pants/legs. Just wanted to know, so any responses are appreciated.

Thanks again guys.

 

their should be afew degrees different in drive temperature. The single platter drive will have one or two heads, (one with 80gb, and two with 160gb)
The 250 and 320gb models will have three and four heads respectively.
Because their is one less disk, their will be less heads, and thus less actuator movement. This will mean a pretty substantial drop in heat.
My 7K320 runs much cooler than my 5400.3 drive from Seagate. My dusl platter seagate ran at 118-124F doing normal work, and the 7K320 runs between 108-116F. The drive runs very cool, and compared to others with the dual platter configuration, the single platter one runs much cooler. I would say maybe a 8F difference at idle, and about 15-20F difference under load.

What computer are you running it on, because your server replacement I'm sure had more than one fan, and ASUS G1S runs very hot, so you can understand.

 

I am referring to my dell e1505 which has no active harddrive cooling

when my server replacement worked the active cooling kept the drives under 104F under full load for hours.

Member Simonov has an Asus G1S, his 7200.3 320GB got up to 60 C.

Yes phil I do have an asus G1s running seagate 7200.3 320Gb

I dont game that much anymore, so my temps dont peak either, but it is certainly true that your temps will rise. When I check speedfan right now it says:
HD: 48 C and both cores 55 C (im just surfing the net now)

during some hd tests temps rised till 60, and then I just stopped the tests to be sure

Well, I think its doing nice now, with undervolting, and even overclocked a little...
Maybe I should mention that I made a 'Knex-stand' for my notebook, so the back of the notebook is like 8 centimeters higher then normal.

If you want me to check somtin out, just shout and explain what to do lol

 

I can see two reasons for a single platter HDD using less power: (i) There will be slightly less frictional drag from the platter spinning in air (AFAIK they are in air, not a vacuum, otherwise why provide a breather hole on the outside) and (ii) the head assembly will be lighter and need less power to move it around (I think head movement needs more power than spinning the discs). However, the temperature difference may be only 1 or 2 degrees C.

Tom's Hardware shows the 7200.3 as using just over 3W maximum power. You might want to look for a drive with lower power consumption.

I once had an Asus W3A and that kept the HDD warm - up to 60C. perhaps a feature of the Asus design.
