Question about CPU temperature

Hi, I have just built a new system with the following,
Motherboard - MSI 760GM-P23 (FX)
CPU FX 6300
and as this is my first venture over to the AMD side of PC's I have some questions about the CPU temp.
The image below is from my system under load, I'm told that the temp readings from AMD CPU's are not accurate below 40c?
The FX 6300 'package temp' cant be accurate with a low of 13c it's simply not possible in a room that's almost 20c.
What is TMPIN1? I hope that's not my actual CPU temp as 69c is way to high. and a Google search for TMPIN1 brings up lots of forum posts regarding MSI boards, Hence my post here.
TMPIN0 looks like the most likely sensor for CPU temp but I'm just not sure, so which one is it? and where is TMPIN1 reading it's info from?
Regards and many thanks, Dave

What you see with HWINFO is the readings from two different sources. One is the reported temp by the AMD sensor, the other is the same temp but as reported and translated by the Fintek chip that MSI generally uses on their boards.
The differences in readings boils down to the digital signal to analog conversion by the two data suppliers, .i.e AMD sensor/Fintek chip.
If in doubt, always use the higher reported temp as the acceptable one. Quite frankly, I would think what the Fintek reports is probably close to what the real temps are. Common sense will dictate that what you see from the AMD sensor is virtually impossible unless you use liquid cooling.
Also remember that the software in use may differ in readings slightly.
The Fintek chip is reporting 2 CPU temps. I summise the higher as being the CPU core and the lower value as being a sensor in the vicinity of the CPU that MSI has added.
Comparing the info with your HW Monitor, I further believe that TMPIN1 is the same as the Fintek CPU higher temp. TMPIN2 is the one for the lower CPU value in HWINFO and TMPIN0 is probably your southbridge.
If you wish, run both these software packages at the same time and stress your machine in Prime95, Then you can monitor and figure out which ones are going up or down in unison. You may also find that the temps will be a lot closer then.

[SOLVED] Question about CPU temperature

Hi everybody,
I just want to ask a question about "standard" CPU temperatures because my laptop (a Dell Vostro 3700) is permanently hot with the fans on even when I am not doing anything special.
I have CPU freq scaling active with the conservative governor, and I use Gnome Shell 3.2 with an nVidia using the nouveau driver.
Here are "stable" temperatures while writing this post:
# sensors
acpitz-virtual-0
Adapter: Virtual device
temp1: +72.5°C (crit = +103.0°C)
nouveau-pci-0100
Adapter: PCI adapter
temp1: +78.0°C (high = +100.0°C, crit = +110.0°C)
coretemp-isa-0000
Adapter: ISA adapter
Core 0: +73.0°C (high = +95.0°C, crit = +105.0°C)
Core 2: +73.0°C (high = +95.0°C, crit = +105.0°C)
And this is the output of mpstat
# mpstat -P ALL

10:16:50 PM 3 1.36 0.20 0.39 0.02 0.00 0.01 0.00 0.00 98.01
The fan, of course, is full speed (very annoying)
I think that these temperatures are quite high, but I don't know what's really causing all this heating because my laptop is basically idle.
Any suggestion?
Thanks.

Question about CPU usage for video playback

I've asked a related question already on the Safari forum, but would like some clarification, please.
The speed of this iMac is 400 MHZ and whenever I go to YouTube or almost any other site that requires video I see that the CPU usage can peak way up at 80% or more. I have Flash 9 installed which has a minimum of 500 MHZ, so I get pretty choppy video, but that's not the issue here. I can live with that. I keep any other applications closed. I'm often running a small fan over the top of the iMac to help vent the buildup of heat. I can monitor the temperature at the Hard Drive and I suppose that gives me an idea, of sorts, about general temperature conditions inside.
The answer I got was that this kind of CPU usage could be detrimental to the processor as it builds up excessive heat and to keep this kind of video to a minimum.
My question is can anyone roughly suggest what a maximum time on YouTube, for example, would be, 2 minutes, 5 minutes, is 10 minutes too long? I have plenty of RAM at 768. Some guidelines?
Thanks.

Hey WZZZ,
Thanks for the star and kind words.
I'm the de facto Mac guy at my kids' school and we have around 25 iMac Slot Loaders working there. You can imagine they get abused quite a bit. There are 10 running Garage Band in the Music Department. That puts a tremendous strain on the CPU and I'm actually surprised that they run it so well. My son had a 600 iMac running GarageBand, he was complaining that it was getting jumpy and when I looked at it he was running 10 unlocked tracks simultaneously! So now he has an eMac G4 800 and that of course runs a lot better.
So to sum up, with all the abuse of those machines in terms of the CPUs the problems I have with them have nothing to do with that. The problems have more to do with parts of the OS that they toss, headphone jacks abused, CDs jammed in the slots, and the like.
A couple of other related things. I've got Hardware Monitor, demo, installed and I think it reported it could only find the hard drive sensor, if I'm not mistaken - nothing else on this Mac with a sensor. Is that right?
I see references to CPU sensors on 400 iMacs but on the 400 I have here for repair Temperature Monitor reports no sensors. Perhaps there were different versions of the 400.
But very good to hear that the fan is a good idea for CRT related things. Should I keep the fan running-mostly for that hard core CRT stuff- even if the computer is sleeping and the room temp. is only around 62-64 F.? (We need to put on warm clothes to sit in front of this thing now, but worth it to keep this old machine happy).
On the one I did the fan pushed the airflow in the direction of the passive flow of the iMac - in at the bottom and out the grill by the handle.
One more question, more out of curiosity than anything else: If I move this small clip-on fan close to the case - right now it's about 3 feet away and the image is stable - the screen begins to flicker and flutter quite a lot. My theory is that that's happening not necessarily because of electro-magnetic interference from the fan motor, but rather, because the back of the tube is getting cooled unevenly. What do you think?
Well the classic failures that I see in the iMac are in this order:
1) Dielectric breakdown of the flyback transformers internal insulation. This is heat/age related and a common problem with CRTs in general.
2) Breakdown of high voltage electolytic capacitors and regular high voltage capacitors on the neck board and PAV supply.
3) Solder problems with the flyback itself. This is diagnosed by the upside down boot technique.
I used to repair these problems but now it's easier for me to swap the Firewire boards into working 350s. I've got 12 of those in the basement currently.

Satellite P200D-12f PSPBQE - Question about CPU/GFX temperature

Hey guys,
Here are the laptop specs:
TOSHIBA Satellite Series P200D-12F Notebook - AMD Turion 64 X2 Processor TL-62 2.1GHz 2MB Cache, 2048MB DDR2-667 SO-Dimm Memory (2x1024), DVD Super Multi writer optical drive, 250 GB SATA, 5400 obr/min, 17.1" WXGA+ TrueBright High Brightness (1440x900 resolution) TFT LCD Display, 10/100 Mbit Ethernet LAN, 802.11b/g wireless LAN, 56K Modem, ATI Radeon HD2600 256MB dedicated graphics, Built-in Harman Kardon stereo speakers, 3.45kg, Bluetooth, integrated webcam, Microsoft Windows Vista Home Premium Edition, 2 Year International Warranty
I cant find any threads or sites that define idle temp for this cpu and graphic card,
in normal stance and high performance/ playing games.
I have an extra cooler (link: http://www.mimovrste.com/artikel/2210016012/hladilnik-za-prenosnik-akasa-ak-nbc-02b ) underneath the laptop. It does help much but still its running on *53C* (celsius) while surfing the internet.
Without that cooler its around 60C. It sounds strange to me.
When i play games on high performance the core temp goes to *63C*, without that xtra coller *+80C!!!!!!*
I clean the heat sinks every 1 month with a huge compressor :)
I dont let any dust in there. I have the laptop like a year now runs great, but still Im interested whats the temperature of our similar models.
I had some "turn off problems" when i didnt have the extra cooler, but now it runs great, but still im not convinced its the "normal" temp. :S
So plz help a lost soul surfing the internet finding nothing to answer his question :)
tnx

heya
the problem is i hate vista :) i have installed xp on it. there are no xp drivers for this laptop. i mixed with some similar models same components xp drivers and everything is working well now ;) no yellow thingies in the system window - hardware components. all cool. all games running with no artifact and no weird thingies.
but still im interested in the temperature.
i installed the old Toshiba power saver (win xp) works fine but i dont see any difference with it. no effect. cooling method is on high(as it was on the begging) and no changes. i hoped the vents gonna speed up just a lil bit . but didnt.
how the temp sound to u? high or ok? for an AMD cpu :) the gfx is at 29C :) the cpu runs at 50C surfing internet , while playing games it goes to 63C.

Question about cpu support

Hi have been absent for awhile then about two weeks ago I stopped here regarding a prob I was having with my mouse. I read a post aabout somebody who had successfully changed his cpu multiplier using the k7n420 which nobody had reported doing successfully for several months after the boards release. At least that was my impression. After confirming that someone had done it and that after updating their bios to 2.6 the multiplier could not be changed again I decided After six months of running steady at the default settings. I busted out my silver pen and proceeded to unlock my athlon 1700. To my utter astonishment I could now freely set the multiplier. My previous systems were all overclocked and I had a watercooling rig mothballed in the closet. My question is if the k7n420 will support the 2600 does that mean that the bios will include a fsb of 166 or will the multiplier on the new cpu's be higher than 12.5. My current settings with the unlocked cpu and watercooling have me maxxed out at 12.5. I blew up one of the first boards I had by using the fsb as a means of overclocking and do not wish to risk the same "early chipset initialization death". But I have upped it a little and the system is unstable at anything more than one notch above default. However the system is fine with the default settings and I am currently at 12.5 with the voltage at default. increasing the default voltage did not improve the trouble when I increase the fsb. So I was hoping that a bios release would either include the 166 fsb or a higher multiplier if there is one (I dont think there is though). It seems to me that if they are to support the 2600 there will have to be a change because at default and 12.5 XP2000 is the limit.
PS The ring buffer problem appears to be related to a 24x10x40 cdrw from iomagic which I had bought on sale for 49.99 "I couldn't resist getting one for the price." After I noticed the ring buffer error in the event log always followed an atapi controller error and the a cd error I removed the iomagic burner and put my previous LG8120b back in and have not seen the problem since. iomagic was less than helpful and after researching the burner I found pretty much nothing other than others looking for help with the same burner. Their is no information on firmware for it and some of the mostwell known cd info sites hardly even mention it. On top of that the support guy I chatted with didn't know nvidia had a chipset and told me I probobly had a via even after I explained to him that it has been around for awhile I closed by suggesting he go to nvidia's web site and see himself. I mean really they already have another chipset about to hit the shelves how can a tech support person not be aware of these things.

rosmini,
Since you are on Tom's Hardware site, they have a video, which has been referenced in this forum several times, on how to safely unlock the processor.
I would not bother with trying to unlock the processor until they come out with the next series of chips. There is talk of the 2400+ and 2600+ coming unlocked. Then the processor you have with we worth peanuts and then if you want to take a chance on trashing it, go for it.
Your best bet is just raising the FSB a few notches and you will get the desired effect and more. It give you a higher processor speed but most importantly you get the greater memory bandwidth. That is where you really see the benefits. Look at the GeForce Cards as an example. Overclocking the Core does little, but overclocking the RAM makes major boosts in performance.
Take Care,
Richard

Question about CPU upgrade for Satellite A30-104?

Hello,
My Satellite A30-104 has recently come to the end of its warranty, and having had to open up the heatsink for cleaning and seeing that the CPU was accessible, I wonder if there is any (likely) scope for upgrading it.
The processor is a Celeron (Northwood) 2.6GHz. I'm not looking for more grunt, I'd prefer a lower-power chip, though the much larger L2 cache of a Pentium 4 is also desirable. I'd be very grateful if anyone could advise whether any upgrades are likely available, and if so which chips would be appropriate? If I can give any more useful spec information, please ask.
Thanks in advance.

Hi, thanks for the reply -- and sorry it went ignored so long, it turns out I hadn't configured my email watches correctly :(
I appreciate that it's really a job for a technician, and I don't want to brick a perfectly good computer, but I think its EOL is not far off anyway so I'm prepared to be a little more invasive than before.
I know that I can get at the CPU, and I know the basic precautions for physically tampering with PC internals.
What I'm first of all concerned about is this: if I replace the CPU, and it doesn't function with the laptop, can this damage other parts of the system such that it'd no longer work by replacing the original?
The Celeron puts out a great deal of heat (all the time) but isn't it fair to assume that a P4-M will be less hot?

Wondering about CPU temperature

Hello, my system specifications are below, I am cooling the CPU with the retail heatsink (dont know but I think it is the first version, it has a copper circle which is in the aluminium block, the fan is AMD one, and it runs at ~4800rpm.
All temps in Celsius.
The temperature never gets over 55 degrees, and idling it is ~39 degrees. Are these readings right? Because I thought and have read that AMD processors get usually hotter than this.
If they are right, then I am happy haha. Anyway I am looking forward a Volcano 12.

temps are fine

Need help ASAP, have a tough question about CPU and BIOS...

Alrighty guys... I'm not super smart when it comes to BIOS and the nitty gritty computer stuff, but I know my way around. Here's the thing...
This is the desktop I have:
http://h20000.www2.hp.com/bizsupport/TechSupport/Document.jsp?lang=en&cc=us&taskId=120&prodSeriesId=...
It's sorta old, but it gets the job done quickly. I had an issue with it some time ago and I thought it was the power supply, so I replaced it. While I was waiting for the power supply to arrive, I took the CPU out, just to be nosey. I accidentally bent a couple of the prongs, so I had to get a new one.
First, I bought a Black Edition AMD quad core, but the 125W was too high for my 95W chip. I had to sell it. I sold that and I just bought a new one:
http://www.cpu-world.com/CPUs/K10/AMD-Phenom%20X4%209850%20-%20HD9850XAJ4BGH%20(HD9850XAGHBOX).html
I put it in the computer, boot it up and it goes to the HP boot screen and then goes to a black screen stating that the CPU is not compatible and that it's going to shut down. When I reset it and try to press F10 or any of the keys it states that it's going to go to that screen, but then just goes to the black CPU shutdown screen again. There is one thing that the computer will do though. When I press F2 when it's in the black shutdown screen, it will SOMETIMES load the two HDD's that I have. It's just really weird. One time I got it to go to a HP diagnosis page. It showed the CPU and had a big green check next to it. It checked the memory too, and it got a check. Then it just froze and I had to shut it down. I can't seem to get it to that screen again.
My real question is why won't it recognize that my CPU is compatible? Do I need to update my BIOS? Can I do that without a CPU and a running OS? I really don't feel like selling this processor. I know that I should have just gotten the exact same processor model that came out of it.
Any info will be nice! Thanks so much!!

Here are the specs for your HP Pavilion a6720y Desktop Computer and it's M2N78-LA (Violet) motherboard. According to the specs, your computer supports the following CPUs;
Socket type: AM2/AM2+
TDP: 95 watts
AMD Athlon X2 (Bt)
AMD Athlon 64 X2 up to 6000+ (W)
AMD Phenom Triple-Core up to 8xxx (AM2+) (Toliman)
AMD Phenom Quad-Core 9xxx series (AM2+) up to 9850 (Agena)
Based on the CPU part number supplied, you purchased another 125 watt CPU. The AMD Phenom X4 9850 (HD9850XAGHBOX) isn't going to work because it is rated at 125 watts and therefore is not compatible with your motherboard. Please consider returning (as Dave suggests) or selling your current CPU and getting one of these 95 watt AMD Phenom X4 CPUs.
Please send KUDOs

Question about CPU FSB and K7N2-L

This is probably a nub question, but here goes anyway:
I currently have an 1800 XP Palomino processor which supports 266mhz fsb. I just installed this board with this processor and left all the jumpers at default. After reading the manual it says I should short jumper J11 (133/166mhz) on the mobo, and make the appropriate settings in the bios to achieve 266mhz for the cpu fsb. Now, I know it says this in the manual, but I thought I'd better make sure that this is the right procedure before I go ahead and do it so I don't screw anything up.
If anyone could help me out on this it would be greatly appreciated.
TIA

Cheers... it's interesting how many people make that mobo/RAM choice. I use a K7N2G-L with Crucial PC2700 DDR (2x256) and it works fine. Kudos on reading the manual, frequently it has the answers you're looking for. You're correct... make sure J10 (FSB Mode Jumper-133MHz position) and J11 (FSB Frequency Jumper-133/166 position) are set correctly, BIOS settings on the "Advanced Chipset Features" page are correct for your processor/RAM, and you should be all set. There is a good article on driver loading order (by liquidsoul) on the http://www.amdforums.com site... look under "MSI Motherboards".

Satellite X205-S9349 - Question about GPU temperature

Hi,
I purchased an *Satellite X205-S9349* approx. 10 months ago an recently installed a temperature monitor for the nVidia 8700M GT card. While using 3d modeling applications I recorded the average temperature at *97 degrees Celsius*.
Idling the computer results in a temperature of *60 degrees*. The computer is present in an air conditioned room, who's average temperature is *19 degrees*.
Is this the normal operating temperature of the X205-S9349 when on full load?
Can this temperature damage my computer?
Is there anything I can do to reduce the temperature without voiding the warranty provided by Toshiba?
Thanks in advance,
Pabst
PS: I have propped the back of my computer up so that air can easily flow through the bottom.

Hello Pabst
In my opinion there is no reason for panic. If you use original Toshiba display driver your notebook is protected and if the notebook will come up to critical temperature level it will shut down automatically to avoid hardware damage.
This with propping back side is great idea. Sometimes I do the same. The notebook can be cooled much better. And one more thing: do not believe always what those third part applications show.
Good luck!

Quick question about cpu cooler

i just orderd the things in my sig and i wonder if the zalman cpu cooler works on the hot peice of hardware that the K8N Neo 2 is? my biggest concern is the corsair memory sticks which might be too large to "work" with the cooler. all help is appriceated

thanks pitbull! now i only have to get the things then i am all set up and ready too go. now i just hope that i get the Zalman with the "working" backplate and that slight littel problem that the fan is a tad heavy so i wonder if i have to be special carefull when go too lans with that huge thing hanging on my cpu, hopefully it will work. Thanks again

run on this board I see it can handle the 333FSB but I dont see the Barton listed as a CPU? Any Ideas? Thanks Guys/Gals :D

Thanks for the quick replys I figured it would but i wanted to double check it out first with the forum, Has anyone actually ran this chip on this board yet? if so what kinda of problems if any did you run in to ( i know this board had ALOT of trouble with FSB settings and all for awhie there.

Pavilion DV7 CPU temperature

I have a DV7 Product WA009EA#ABU (i7 cpu 1.6Mhz circa 2010) running windows 8.1 (mistake!).
Since installing angry birds I've noticed during play the fan is constantly running . Installed realtemp which shows cpu temps rise to typically 75-80C. So I've some questions about CPU range, maximum and whether use of say speedfan 4.49 or chnaging the power configuration can control max temp.
I have cleaned the vents using a vacuum cleaner several times but am loathed to attempt to clean fan as this seems to involve almost complete disassembly of the laptop.
1. What is the ambient range and sustained safe maximum for thei laptop / cpu?
2. I'm still on the original BIOS - any adavntage updating?
3. I have tinkered with the POWER configuration and changed the plugged in settings to be active for cpu fan. Also reduce the performance to 80% which seems to reduce the temparture?
4. Any conflict between configiring the POWER options and using auto fan speed in SPEEDFAN?
5. I've noticed the cpu speed varying - I presume this is an i7 feature - can this be controlled.
Or am I worrying unnecessarily!
Thanks

try to see if you can remove the keyboard. when the fan is visible, just run a vacuum cleaner on it. this should do the trick. overheating while doing hardly anything often indicates dust near the fan

K9N Platinum - Wrong CPU Temperature in BIOS

Hi, I have a K9N Platinum (7250-020) with the latest 1.3 BIOS and an AMD X2 3800+. The CPU Temperature in the BIOS has a negative sign in front of it, and it seems to always report -48*C. I tried the latest nVidia nTune and it was reporting the CPU temperature to be 208*C, which is absolutely impossible...
Does anyone have the same problem? I searched around and it seems I'm not the only one, but I still cannot understand if it affects only some K9N Platinums or all...
Thanks.

I assume you are talking about checking voltages as reported by the BIOS in the HW Monitor page, not physically checking them with a multimeter, correct?
I'll take a look at the numbers in the BIOS, but last time I checked they were ok.
As for raising the issue with MSI, eventually I will, even if they ask you soooooo many questions (for good reasons, I know...) that it would take me half an hour to fill that form...
I've checked with both and software is a little out from what a multimeter state's. Only check with a multimeter if your happy to do so. http://forums.extremeoverclocking.com/showthread.php?t=137886 offer good advise if using a multimeter .....

Mac Pro 8-core X5365 CPU temperature

I've got an 8-core Mac Pro which is crunching SETI@home 24/7, with Hardware Monitor monitoring the CPU temperatures and other vital stats. After reading the Intel Quad-Core Xeon Proc datasheet, I'm a little edgy about the operating temperature of these X5365 CPUs, currently registering at 65 - 70ºC on load for each temperature diode, and fail-safe temperature set to 73ºC to disable SETI@home via Hardware Monitor. I also have smcFanControl speeding up the fans because my ambient temperature varies thanks to myself being in a tropical region, my ambient temperature can reach 33ºC at times, but down to 28ºC when air-conditioned.
My question is, what is the maximum temperature for these CPUs before they run into the risk of being fried/permanently damaged..?
Inputs from the Mac Pro-DC/grid community are also welcomed here.
Thanks.

my 8-core is running seti 24/7 since may without any problem, although my ambient temps dont rise above 30 degrees centigrade...and that's using the optimised apps which make the processor run hotter
the fans on the machine run 600-2000 rpm all day and all night, i dont expect it to lessen the life of the machine whatsoever. it should be capable of running flat out all its life, that is, after all why we spend so much on these machines in the first place !
if you only use 4 cores perhaps you should buy a 4-core mac ? he heh just joking...
as mentioned earlier, when things get really too hot the OS will shut the system down, and if that doesnt happen then the cpus themselves will shut down...
the heatsinks and fans on these machines are fully capable of coping if your macine is running withing the specified ambient temp range which for the mac pro is 10° to 35° if your seeing ambient over 35 then smc fan control is probably a good idea otherwise it should be fine
