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?
-
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.
http://software.amiga-hardware.com/software/thermometer.lha
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" ;-) )
-
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...
-
Blob . . .27-30 degrees misured where?
-
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)

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 :-)

@Framiga
sorry blob but they are fake
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.
-
Piru . . . its impossible anyway!
Your themperature reports, are more credible.
27-30 degrees, only with a case opened.
-
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
-
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
-
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:

of the HD
-
Many ATX cases come with hardware temp sensors that display their results on an LCD screen at the front of the case. Much the same as on that case of Blobrana's I imagine.
The ambient temperature of the room I am sitting in right now is 11 degrees Celsius, and it's bloody freezing! :-D
-

ohhh . . this is the key point.
I think that everyone, has his references for "things" in general.
To claim the your (or whatever else HD-CPU_chipset) runs at ## degrees, its relative (and not an absolute reference).
Thats all :-)
-
Piru . . i gues that you want to litigue (as in your habit) and not and not to discuss/speak civilly.
You were right and i was wrong . . are you happy now?
-
@Framiga
i've always found the the various themperature
reports (don't care if on PC-Peg-AOne) are almost fake.
And I've found that using uncalibrated temperature sensors is always a bad idea.
S.M.A.R.T drive sensors are at least calibrated, and temp measured inside the drive, rather than somewhere outside where the airflow can affect the result.
I haven't so far seen radically wrong readings from S.M.A.R.T.

Hum,
time for an Ambient Temp thread?
Over here 20 degrees Celcius (do not ajust your heating)ambient temp.
Here another image with SETI switched off..an fans put onto stealth mode

And link to Startech 2-fan Hard Drive Cooler (http://store.pcpowerzone.com/star2fanharc.html)(http://store1.yimg.com/I/pcpowerzone_1846_19876746)
(Its cheap, but one 3" silent fan will do the same job if you can mount it to blow air (between/over) your HD)

@orange
Anyway. Back to the topic.
All 'newer' HDDs work with 7200 rpm and get very hot.
Not all hard drives. For example Seagate Barracuda 7200 remain <45 C with about 20 C ambient, and no airflow except PSU.
Many Amiga IDE and SCSI controllers can have HDD mounted directly on card. Can that heat damage the controller?
Actually I'd be more concerned about the drive itself, rather than the controller. If the drive remains under the recommended maximum temperature, then there is no problem (for the controller either).
I suggest you refer to the manual (online or physical) of the harddrive in question and mount a temperature sensor to figure out if the temp raises above the max with some stress test (copy lots of files around for example).
If it stays below the max, you're safe.
If the temperature gets close to the limit or even above it, then you should arrange some extra cooling. In most cases adding a fan is enough. In some rare occasions special harddrive cooler kit (HDD heatsink enclosure + fan) might be needed.
-
My Seagate 120GB disk's temp is between 30 and 35C on average. I'd hardly call that hot.
-
Hum,
but if it was a competition as to who had the coolest HD then you would lose.
But yeah, seagates are ok. (i havn`t had too much probs with maxtors though a few ppl have said they blow up and are a bit noisy.)
:-)
(has anyone mentioned buffers yet?)

Hmm... I wouldn't really call this hot, either... A 120GB Western Digital S-ATA 7200 RPM with no active cooling on it, other than (closed) case airflow.
(http://home.comcast.net/~ilwrath/speedfan.jpg)
Local Temp is the CPU core. (P4 3.0C HT)
Remote Temp is (I think) chipset. (Intel i865PE)
HD1 is the hard drive (shows as 1 because it's on the SATA bus.)
Temp 3 is case temperature.
I don't think Temp 1, Temp 2, or Temp 1 (again) are hooked to anything.
And these readings are from a room that is currently a rather sweltering 27C.
With some strategically placed fans, a little ductwork, some good heatsinks, and artic silver, you can keep the most notorious hot-running rigs cool, even in adverse conditions. :)
What was the point of all of this? Well, I'm not sure. I got derailed somewhere. I think I was just trying to say that you should go for the hard drive you want, and if you're concerned about heat factors, get some monitoring going, keep an eye on your temperatures, and think about case layout for a day or two. If the temps are higher than you'd like to see, add some more cooling to some strategic location. :)

Above a surtan point heat will start lowering the life expectansy of a harddrive. If the airflow is bad around the cards (witch it is in most cases) and you have a drive that's running hot I do belive there's a chance of damaging components on the controller ther drive sits on aswell as cards close by. You're much better of monting the drive somewhere else in the chassi.
In the new tower (Cooler Master Stacker) for my A4000, fans will keep the drives cool (coolermaster got this nice module to mount four 3.5" drives in three 5.25" slots with a fan in front of it and rubber barings on the sides for lowering noice).
I've killed a drive by keeping it in one of those plastic harddrive racks without a fan you can get for like 10$, that's why my new rack is made out of aluminium and have a fan (with controller on front) aswell as a heatprobe, display and alarm system (nice little thing that set me back over 50$). Just to be on the safe side and to lower noice even further in this tower I got myself a CoolerMaster Aerogate3 to controll the 4 fans that sit in the tower... it also have 4 heatprobes (and display) so I'm thinking of having it check the PPC, 060, Voodoo3 and my 9Gb UWSCSI drive.
Yes I'm letting go of the firm grip of my wallet to finaly give my A4000 a pallase of a tower. :-D
