None of the temparature sensors found for AMD turion

[samjoandco]

None of the temparature sensors are found by either Temperature Monitor or MSR Tools.
In fact MSR tools shows blank screen with "CPU 0" & causes kernel panic in few minutes.

I read a few posts that OSX tends to overload the CPU and might fry the system or cause Thermal shutdown.

any inputs on how to get the temperature sensors detected?

Yeah, mine don't show up on iStat or MSR Tools, either. If someone knows of a magic fix for this it'd be nice. Meanwhile, the BIOS beep for if the CPU reaches 60C serves well if your system has such a feature, as it (in my experience) even works in OS X. This can warn you if your processor's getting a little toasty.
Personally, though, I've had it get toastier in Windows than OS X. Until I threw out the stock heatsink, anyway. Now it usually sits at 75F (or so I can tell in BIOS and Windows, not as sure about OS X but no BIOS beeps anymore, even under load, so...).

60°C ??? Has your cpu reached this temperature yet? My Opteron 185 gets at 2.95 GHz never higher than 44°C, in normal use maybe 38°C. OK, this thing is in an open HTPC case and has a huge Scythe Mugen (http://www.scythe-eu.com/en/products/cpu-cooler/mugen-cpu-cooler.html) cooler, but my second Opteron 185 which runs at 2.8 Ghz is in a closed case, max temperature was 48°C, normal maybe 41°C. There's a Scythe Shuriken (http://www.scythe-eu.com/en/products/cpu-cooler/shuriken.html) on it.

The BIOS of my board has very advanced overclocking options. Do you have the possibility of adjusting the CPU voltage? I'm running mine at 1.28V which is the minimum for an Opteron. But it works great and the CPU stays much cooler as with the default settings.

Mine is a inshydeh2o bios in HP Pavilion craptop. The bios is a very primitive one with very limited options.

[Ali C.]

Ah, that sucks. :(
And for the record, my CPU was getting to where it would hit 60C regularly in either OS. Stupid stock cooler. :p

A friend also had heat problems, the CPU even switched itself off :D Now these things can do this, as I was using an Athlon XP suddently the taskbar in Win XP went black, then after I closed some windows there was more black. I pushed the reset button and took a look in the BIOS - 92°C !!! The fan stopped without reason. But this processor is still working!

There are various AMD stock coolers, the aluminium based ones had only two series which are really quiet. I know the bigger coolers for the Athlon FX and Opteron series, there are two versions, one has all heatpipes on one side and the other one has two on each side. They also differ in rotation speed. Which version do you have? Do you have the older version with the holograph on the fan?

There are a lot of reasons if a cpu has a high temperature. If you want to test another fan I can recommend the Scythe Shuriken. It is very small (64 mm height) and absolutely easy to mount. And use some good thermal grease, I'm using Arctic Silver 5. I only apply one pea-sized drop in the center of the cpu and some small drops in a circle around it. While mounting the cooler I twist it a bit on the cpu, so the grease will become only a very thin layer. But beware: This stuff is sticky as hell. It needs some cleaning sessions for cpu and fan, even when using isopropyle alcohole. If you hate someone, press him a tube Artic Silver 5 in the inner pocket of his jacket. He NEVER gets out everything :mad:

Another thing is the airflow in the case. I'm only using a 8 cm fan at the backside and a Sharkoon Silentstorm power supply which has a 9 cm fan on the bottom and an 8 cm fan at the back. My gfx cards are all passive, so they should produce more heat, but it doesn't seem to be problematic. My harddisks (I've got 3-4 in every computer) are all from Samsung, they have a temperature around 37°C. You can touch and carry them after hours of using, try this with an Hitachi HD which gets up to 55°C! I'll now add another 9,2 cm fan before my HDs which keeps the heat from getting in the inside.

Here's a list of my favourite manufacturers and products, all components are very silent.

CPU coolers: Scythe Shuriken, about 25 Eur (Mugen is too big for standard cases)
Thermal Grease: Artic Silver 5, about 5 Eur
Case fans: Sharkoon, about 6-8 Eur
Harddisks: Samsung, highly recommendable is the Spinpoint HD103UJ, it's amazing fast, quiet and cool. I got them new for 73 Euro!!
Power Supply: Sharkoon Silentstorm 480W Dual-Fan, on ebay about 25 Eur. 480W seems to be a bit weak, but this thing has a combined power of 384W ! You can buy a 700W PSU, but if it has a combined power of only 115W then it's crap, if you have a big cpu and gfx card it may even not be able to start the computer. The other power supplies I'm using for my other computers are no-names from x-super, 550W and combined power of 235W. The Sharkoon Silentstorm is also interesting because it has very long cables for the CPU power supply, good for Bigtowers and for fullsize-ATX-HTPC-cases which have the PSU at the front (like mine).

Good tips. Should help out others. :D
My 5000+ came with a junky aluminum heatsink. When I found I was doing everything right (don't put the AS5 on like peanut butter, make sure it's seated good, watch airflow, etc.) and the heatsink still just wasn't cutting it (which is sad seeing as I didn't even overclock), I got a Freezer 64 Pro, recommended by a friend. Haven't had my computer beep at me once since then.
As for my hard drives, they've never, ever gone above 110F. And usually they stay at 95F. They're a pair of Seagates but I wouldn't recommend them after getting burned by some dying drives lately. I'd actually like to get one of those Samsung drives.

Hmm... if I'm counting, the fan of my Athlon XP which fell out was an Arctic Cooling, the one which I had on my FX-55 which I owned for some time was an Artic Cooling 64 - temperature up to 55°C, my friend which CPU was turning istelf off also is an Artic Cooling, a very fat thing with hig heatpipes and so. I never counted this, but if your cpu also gets very hot with the Arctic Cooling stuff then it may be a reason to think about changing the cooler.

I hadn't the FX-55 for very long time. I bought the Artic Cooling for it, but it was much to hot with it. I reverted to a big AMD cooler, but it was too loud. So I sold the FX-55 again, there was no noticeable speed difference to my 4000+ which only has 200 Mhz less. In 2007 I got a bundle with an Opteron 185, board, RAM and a huge Scythe Mugen cooler. It wasn't possible to get it into a standard case, so I put the thing in my HTPC case which has to be open all the time. But you don't see it because it's directly unter a table. This thing was great, and after I got my second Opteron 185 I wanted to buy another Scythe cooler, and I chose the Shuriken. Because it's so flat there's a good airflow to the back cooler. And this thing also works great, even in a closed case. I got for my parents an Opteron 180 now (for 44 Euro!!!! :D:D:D), they also get a Shuriken.

I was never a friend of non-standard cpu coolers, maybe due to my bad experiences with Artic Cooling. Or so monstous Zalman fans for which the backplate must be replaced or some other rework is neccessary. But I'm really convinced by the Scythe coolers, they fit on nearly every socket by using special adapters and especcially the Shuriken doesn't need any mounting tools at all.

You can take a look here (http://naquaada.na.funpic.de/naq/pics/computer/macbox/) for some pics of the inside of my 2nd system. It's not a reworked G5 case, it's a normal ATX case, but rather deep. Including the handles the case is squarely.
The third pic may look that the CPU cooler and the bottom of the back fan is at the same height, that isn't so, the cpu fan is about 1cm (0.4 inch) higher.

That's actually the wrong technique to use for applying thermal paste. You're using too much. Barely more than the size of a grain of rice is what Arctic recommends. Any more and it may squeeze out beyond the CPU package. I use the recommended amount and it covers the whole CPU once it's compressed. Multiple spots are also not recommended as they could leave trapped air in bubbles between them. One spot in the middle will spread out by itself.

Passive graphics cards don't produce more heat. It's the same amount of heat as any other card using the same chipset, just not removed from the card as quickly and efficiently.
