7200 rpm

[orange]

All 'newer' HDDs work with 7200 rpm and get very hot. Many Amiga IDE and SCSI controllers can have HDD mounted directly on card. Can that heat damage the controller?

[Tahoe]

I have a SCSI 10.000 rpm hard disk in my A4000, it gets hardly any warmer then my old IDE drive. It is however mounted on the normal HD location in the 4000 (between the powersupply and the zorro daughterboard)

mhhh . . .it depends by the model and air flown around.

One of mine 10000rpm has an internal temperature probe that shows 45 degrees C without cooling and 37-39 with a little fan placed near the HD.

works only with SCSI. (only if the HD has the probe)

EDIT- anyway, if you have space enough, don't install the HD over the controller card.

I was going to ask the same question. I have a 4200 RPM 2.5" HD in my A500 and it gets very hot - the hottest thing inside the Amiga. There's no way to place the drive any other way than directly on the card and I hate fans.

I need to replace it and want a 7200 RPM drive, but was worried about the heat. I've heard some people say the 7200 drives are no hotter than the 4200 drives, and others say they're much hotter.

Does anybody have any recommendations for a cool 7200 RPM 2.5" HD or is there any way I can search for the coolest one? (temperature wise, not "hey, cool" ;-) )

[blobrana]

Hum,
i mounted a fan to blow over my two HDs and now have a reassuringly temperature of 27-30 C....

i believe you could mount a flat metal plate to conduct away some heat if you think your HD is getting too hot as well...

[Framiga]

Blob . . .27-30 degrees misured where?

[blobrana]

Through software (speed fan)
and also via a temp sensor attached under the cover of the HD (linked up to a nice LED screen on the case)

[Framiga]

sorry blob but they are fake :-(

Is impossible that whatever device, could run on a 6-7 degrees more the ambient themperature.

I've already heard of AOne CPUs running at 30 degrees!!! . . . fake misurements these too.

Bye :-)

No they're not. The information is provided by S.M.A.R.T.

SpeedFan reports the PC hdd to be at 29 degrees celcius. This makes sense since this PC has most cooling in it.

The peg1 linux box:

peg1:~/ smartctl -A /dev/hda | grep Temperature_Celsius
194 Temperature_Celsius     0x0022   110   253   000    Old_age   Always       -
      33

...that is, the hdd is running at 33 degrees.


Pegasos II hdds run at 43 and 44 degrees atm. This is because the machine has minimal cooling. Even 44 is still well below the maximum recommended operational temperature.

Is impossible that whatever device, could run on a 6-7 degrees more the ambient themperature.

Why would it be impossible? It depends on the cooling.

[Framiga]

Piru . . . its impossible anyway!

Your themperature reports, are more credible.

27-30 degrees, only with a case opened.

[blobrana]

cool,
i could add that opening a window/door helps a lot, especially if you place the computer in a draft...

i shoud also mention that there are `silent` fans out there that could fit onto an Amiga case (or under the trapdoor if you extend the legs)



i should point out that i`m running SETI (that is why the CPU is 100%)

Can I add that Piru lives in Finland, and Blobrana lives in Scotland.

Last time I checked there were no sunbathing holidays advertised for either country, unlike Italy! :-D

[Framiga]

eh, eh .  .jokes a part . .

ok they lives in a colder place but i don't think they lives under a bridge! :-)

Honestly, i don't want to do "the school teacher" . . i hate who do it but i tend to don't beleive, to the sofwtare probes . . that's all.

I personally, use a Themp/probe meter (hardware) and i've always found the the various themperature reports (don't care if on PC-Peg-AOne) are almost fake.

@blobrana

i'm not saying that those progs, are unusefull, they are and a lot.

They give a rough idea of the themp status but, above all, let you know if something is going wrong . .  .nothing more, nothing less

[blobrana]

yeah,

you cant rely on the accuracy of the software, and HW probes can be fooled as to where they are actually placed (in the air flow etc)
though in my case the Hardware sensor cable is directly attached to the HD case (and the two readings, SW/HW, tally).

BTW - HEY!  it’s a hot sunny day outside, it doesn`t always rain here....time to sunbathe....

I guess you missed blobrana's comment:
