Overheating problems

[asingh]

Is there any one here Experiencing the Heating problem from phenom 2 940 ??

asigh & topgear !!!

As i already i discussed with asigh regarding the heating issues of my phenom 2 940 , TOPGEAR i wana ask u ?? u ever saw temperature like this ->

My CPU temp - 35 is OK but Core temp is ?? like hell IDLE - 51 & LOAD - 62-64

wat to do after updating BIOS the CPU temp is reaching 62 IDLE & core temp is 70 idle ??

Hey sorry for such a late reply...net was down due to the heavy rains in Delhi...!

Well....you temperatures seem on the high side. 51C is on the high side for an idle processor, and that too you have a Silent Night mounted as the HSF. But you have an OC'ed processor too, with extra juice going into the v-core.

I would suggest the following:

1. Remount the HSF and clean all mating surfaces with isopropyl alcohol.
2. Use a good TIM (arctic ice/cooler master fusion) People suggest using the 'one grain of rice method'. I do not have confidence in that. Spread it using an old credit card...thin even layer. Once you have mounted the HSF shine a torch perpenducular to the mating surfaces. No light should be leaking through.
3. Bring your system down to factory setting. Everything, including the RAM/GPU.
4. Run PRIME 95 (using RealTEMP) with two worker threads and post the result screen shot here. (Prime95 screen shot)
5. Now bring your system up to the stable OC settings and again post the screenshot. (Prime95 screen shot)

Also if you could tell:

1. What is the AMD listed vCORE range.
2. When you OC'ed did you lower the vCORE once you hit 3.5GHz till your system was unstable.
3. Is the Silent Night pushpin mount or screw down mount. I read some reviews but could not make out. Sorry.
4. What environment are you running the system at. A/C or normal.

Before hand I can tell you what to expect:

1. Your vCore was incorrect and is heating the cores. Too much going into the cores for 3.5 GHz
2. Your HSF was mounted incorrect.
3. You have a CPU which will always run at these temperatures cause of the factory build. It happens it times.

By the way am surprised that you are getting these high temperatures. I just OC'ed my system to:

CPU: 4.0 GHZ
RAM: 503Mhz. Cannot get the EPP 533Mhz since the multipliers for the FSB : RAM ratio are locked. (with 5-5-5-15 timings at 2.1V)
vCore: 1.432V

Idle Temperature: 38C
Full Load (PRIME95): 61C
Environment: Non A/C

Do what I have suggested, and we can take it forward..!

ALSO:
How do I upload a image signature. I tried it from the user control panel. It uploads the image file, but it is not showing up in the posts..??

^^ BTW look @ the techlomaniac post down to me , same temp as not even 1 deg reduced , when i update the BIOS to next version core temp began to run @ 62 degree idle , nothing changed setting s ?? HOW now core temp is 51 updating bios then 62 how ??

 

[Krow]

No damngoodman999, I haven't tried infrared. Pls try what asigh suggested and let me knw.

 

[damngoodman999]

I actually tried thermal paste methods like spreading , rice grain in center , pea method , five dots

3 different types of thermal paste ASUS , Arctic silver 5, INTEL thermal paste

@ asigh phenom 2 940 is 125W TDP , like corei7 is 130watts TDP so heat can be rush up
i think so ??

asus silent knight AL is new cooler

Its like zalman cooler does the decent job !

Or i have to lap the cpu cooler ??

 

[Krow]

damngoodman999, try lowering the voltage of the CPU and see the lowest voltage where you get it stable. Then report as asigh said.

It should not...updated BIOS are more optimized. Your reporting software could be buggy..or the temperature..probes are defective.

Yes..please

Please do not LAP it..no....! Will mess it up. It should be fine-- factory.

I meant was..what are the vCore range temperatures for the concerned AMD processor.

damngoodman999, try lowering the voltage of the CPU and see the lowest voltage where you get it stable. Then report as asigh said.

Yea high probability it is a vCore issue. You have to bring it DOWN to the unstable limit...and then push it up a notch only. And test again...!

 

[topgear]

@ Xeno - you have not posted the temp of your your 160GB hdd ? or I'm mssing something ?

@ damngoodman999 - do what asigh suggested you.

BTW, there are two type of temps for a cpu. One is cpu tcase temp and another is cpu
core temp. Your cpu's tcase temp is normal but your core temp are very high. Instead of using everest use coretemp. Run prime95 for an hour and post the load temps.

For eg. I'm getting tcase temp of 51C and core temps of 40 and 44C where the ambient temp is 29C using a e5200@3.2Ghz with 1.28V vcore @ idle. at load with 1.26V vcore I'm, getting 55 and 57C on cores and 68C on tcase.

As far as I know asus silent kinght AL is no that great cooler -vendetta2 2 is better than that though the temps you are getting not very bad. Do post the load temps as it's very important.

Here's pic of Phenom II 965 ( idle 1.39V vcore ) with 145W TDP @ stock speed of 3.4Ghz cooler with vendetta 2 ( the case temp is 38C )

So there's nothing to worry about


@ Techalomaniac - No need to worry. True can kick the hell out of every air cpu coolers if you use it with amd procs

 

[damngoodman999]

@ Asigh & Topgear

Silent Knight AL is not big competitor to TRUE ! i know but u atleast there should be 3deg drop from the stock cooler does really make sense , not even a single deg dropped comparing to stock cooler

BTW , i can post the LOAD temp honestly using PRIME 95 - CPU temp 52 & core temp 70-71

Ok its 125 watts TDP proccy , the Vcore i set is 50% lower than the stock Vcore !! the stock vcore is 1.34

The Bios shows 32 deg , updating bios then it shows 58deg ???

I just opened the side panel kept table fan near it , then the CPU temp shows 26 & core temp 40 ??

@ TOpgear

The core temp will be always 10deg higher than the CPU temp !!

BTW real temp is not working with phenom 2 proccy's

Hey..not doubting your honesty of reporting the temperatures. Only reason I wanted to see it via RealTemp cause it hand-in-hand loads your CPU+logs (visually) temperatures and differentials to TJMax.

Anyways..it is weird..that the Silent Night is not decreasing temperatures. What temperatures you getting using CoreTemp. Download this and tell.

Else if you have done all I suggested...then you can..

1. Work with stock settings.
2. Roll-back to the initial bios.
3. Or you have bad junction diodes on your chip. So they are reporting out incorrect.

Interesting. Many others are facing the same problem.

I understood in the post prior to this that Real Temp is not working so had asked..to use CoreTemp. Try this application, and tell the temperatures. It has a logging feature too... .CSV format.

Also can you post your stock temperatures/voltages -- no OC. (Please do this). This is really important to see the differentials. (if you posted it earlier..sorry...please do so again)

*************************************************
regarding prior posts
*************************************************

How in the world could you have an OC'ed core and be 50% below stock vCore..??? Something is not correct here.

Also if the addition of a table fan made such a huge difference, means, your HSF is not working correctly / not seated properly.

@ Xeno - you have not posted the temp of your your 160GB hdd ? or I'm mssing something ?

THe 160GB disk is R.I.P its just lying on the desk now.

random thought:
I was wondering if one could actually use a refrigerator's cooling system... I mean it sounds crazy but a refrigerator from the 2nd hand market doesnt cost much. Some of the air cooled cpu / hdd solutions are more expensive than these. On top of that a refrigerator doesn't really consume a LOT of electricity. Its the perfect thing to draw heat away from a source, and therefore, it'd cool a lot better.

Would it be possible to have the inner piping in a refrigerator taken out, with a compressor and a heat exchanger away from the pc it seems possible. Just have the piping sorted of placed on a cabinet's side panel, and have the compressor and the heat exchanger outside. If this works it'd be totally chilled .. I've seen prices as low as 2k for small low end refrigerators from kelvinator (very old ones) .. If the compressor and pump can be set to run at a lower setting it'd work out decent, since it probably will need like 1/4th capability to chill a cabinet than the refrigerator compartment

Pro's
-Refrigerators are quite reliable, esp the old kelvinator ones, I'd one which lasted more than 16 years.
- Can run 24x7. Without much power consumption, barely adds like 200rs per month when you use a medium sized refrigerator with the deep freezer and the cooling compartment at low temperatures, In a pc the temperatures could be set to as high as 20*C and the refrigerator would work actively for very less amounts of time and generating a very minimal bill.
- Possibly the tubing is tougher than watercooling counterparts. Afaik, there are copper tubing inside a refrigerator..
- 2nd hand market refrigerators are very cheap.

Cons
- It's more of a hassle to install as damaging the system would result in vapour leak which isnt cheap to refill.
- Maybe would cause condensation inside the pc.. not sure about this.
- Bulky so can't be used for LAN parties etc, portability is hampered.
- Compressor might cause a humming noise.

Any thoughts on this ridiculous idea ?

Yea..even I have thought of this..

1. Refrigerators run on phase cooling. So the compressor would not be always running, and the blocks will not get a constant cooling.
2. For sure condensation will happen where the coolant pipes are touching the computer parts.
3. Basically the fridge works on the concept of running the compressor for a while, then switching off. It assumes (and correctly so), that the food inside the compartment will not warm its self up. So energy is not constantly being increased within the fridge. For a CPU it is constantly getting hotter.

But nevertheless, I did see some forum exclusively dedicated to this. Will try to get the links, and post her. It showed cabinets, with compressors embedded in them.....!!!!

 

[rishabh9]

Hi! I too am facing over heating problems like many others on this thread. The CPU reaches 96-98 degrees!! Please help me.

My system configuration is as follows:
AMD Phenom™ X4 9650
ASUS M3A78-EM - motherboard - micro ATX - AMD 780G
Corsair CMPSU-450VX
Transcend 2GB RAM 800MHz
Zebronics Bijli Cabinet
(No graphics card installed yet. Using inbuilt. Will be adding one soon.)

I don't have anything for cooling apart for what is provided with the processor and in the cabinet. BTW, I have added an extra fan to the cabinet.
What should I do now, to lower down the temperatures?

1. Should I buy another cooling system? Please suggest some. My budget is 2-3K
2. If I add a graphics card, how will it affect the heating/cooling of the system? What will I have to do then?

Thanks!
Rishabh

Yep, good points there. While I may not ever need this sort of cool it seems interesting.

The issue that the fridge will be always on is an issue. That'd result in a quick compressor kill. I just wonder if the thermostat could be set to a much higher temperature (cause max on fridge I know is like 10*C ) so that the compressor will not have to work that much to cool the system, after all we dont want temperatures below 15*C do we ? even if it runs at room temp it'd do just fine.

I know that it all could be solved with a tablefan instead of a refrigerator but meh, i have this science bug in me somewhere which is biting now

How are you measuring your temperatures..?
Any OC...?
Did you use any TIM..?

The GPU should not heat the CPU...

 

[rishabh9]

I read the temperatures from my BIOS setup.
I haven't OC my Processor. And pardon my ignorance, I don't know what TIM means.

I have found my self another problem. I use ubuntu and the 'sensors' package shows me opposite results! i.e. the temperature reading my BIOS shows for my MoBo, the 'sesnsor' app shows it for the CPU and vice versa ... now I dont know who is giving the wrong readings!

ooooooh...! Those are hot...man. Can you download CoreTemp application and tell the temperatures. Pick it up from here.

It seems you temperature probes are reporting incorrect you cannot have -ve temperatures...

Also see if you can get Lavalys Everest sensor readings..

TIM = Thermal Interface Material. It is the grease you apply between the heat sink fan (HSF) assembly and the exposed CPU core top.

dude the apps you have specified are windows specific. And I use linux - Ubuntu... want me to run them using wine?

@ damngoodman999 - Realtemp does not works with AMD procs so you only have to use coretemp

Sometimes mid range 3rd party coolers does not affects the idle temp as even my hyper 212 is has not reduced my procs idle temp but it works as wonder on load temps

The load temp you are getting is a bit higher - it should be between 60-65C.

As you are getting less temps when you kept opened your cabby _ i suspect it's all about bad ventilation inside cabby that is affecting your cooling performance.

BTw, what vabby do you have and how many fans you installed ?

@ Xeno - I just thought you got a replaced 160GB HDD so asked about the temp

@ rishabh9 - what's your mobos temp readings ?
CPU? MB ? Cores ?

BTW, update your mobo bios - you should believe what mobo bios is showing to you other than the sensor app.

If all fails then remount the cpu HSF using some good thermal paste.
