"NEED SOME HELP" Phenom 2 940 - TEMP on wild

[damngoodman999]

Guyz , i recently bought Phenom 2 940 on stock speed & stock cooler the temp i really get

IDLE CPU temp - 50
LOAD CPU temp - 65-70

Core temp is 70 & above on Load using PRIME 95

My cabinet temp shows only 32c , i dont what to do i just chaged thermal paste 3Thrice i put INTEL thermal grease -which comes with the intel mobo replacement , i tried all settings even disabling C&Q , nothing works

I update the BIOS to F3a My motherboard is in the Signature , dont know what to

Everything i added PICTURE which shows temp & information .










NEED HELP ????

I see everything here including the hard drive as pretty warm than preferable depending on the ambience you have where you live. Let's start off with the basics:
# Which case and which fans?
# Have you done cable management?
# Room temps of where you live at?
# Why did you change the thermal paste?
The stock heatsink has good enough thermal paste as far as stock is concerned.

# What are the temps shown in bios?
I have seen certain people from other forums complaining about these temps but the difference between bios temps and once reported here are way different- about 10 degrees lesser in BIOS.

[damngoodman999]

For u questions

The Sorcerer
# i posted my picture of my case , i added 1 X120mm fan 4 X90mm fan
# picture shows my cable management
# Room temp 27c-31c
# the HSF is hard to firt with this mobo the thermal paste were rubbed by my hand , so i added new thermal paste
# BIOS temp 51c for CPU

My Bios & CPU temp is equal , what about the Core temp ?? why is it equal to CPU ??

@damngoodman999

The temperature is detected by a separate chip on the motherboard. There are chances of you getting false/inaccurate readings. I, for example, get a reading of 72C for my IGP on the my Zotac 8300 board and the voltages on the 12V rail is showing 8.7V which I know for sure is definitely wrong as it is a new board and got it exchanged for this same reason and the problem still persists even on the new board. I figured the problem is with the sensor chip (WinBond in my case).
So you don’t have to worry too much as long as there’s no performance hit or any other things going wrong. As the saying goes – “ If it ain’t broke, don’t fix it”.
Happy computing!

[The Sorcerer]

When you said the thermal paste was rubbed off you hand, did you clean it using isopropyl alcohol and made sure the hsf is fitted properly? Not doing so might destroy the thermal properties and maybe even electrically conductive.

Its clearly not the processor issue since everything seem to be warmer than the preferred temps- especially with that room temperature. Get rid of the rear exhaust. Make sure your front and rear fans are atleast 120mm with 50 cfm. Sometimes depending on the layout of the system even extra fans can damage/have no effect/ support air cooling.
IMO, you should wait for newer bios updates.

[damngoodman999]

Before updating the BIOS the temperature is normal not low but around 45 idle , but many game crashed in the OLD bios ??

after updating the bios the games run smoothly ???

u can try touching the heatsink and heatpipes with ur hand at full load. Be careful not to touch the mobo circuits or ram chips. It perfectly safe if u touch the heatsink or heatpipes alone.
See if its too hot.

once my old cpu showed 80c, which i didnt believe. ive touched the heatsink, and it was pretty hot to touch.

Pretty wrong way to judge the heat this way. Heatspreaders and heatsinks are meant to dissipate heat from the source- the chipset in this case. So its obvious that it will be hot. Judging chipset's heatsink by touching the heatsink wont give anyone a clear idea- even remote from an approximate idea.

[dOm1naTOr]

When my CPu runs at 40~45c, the heatsink feels kinda cold, while it seems hot on 70c.
So in any case, the heatsink wont get hotter than the CPU at anytime. And the heatsink temps will be pretty close to actual CPu temps, as the heatsinks absorb the heat quickly.

And if the Heatsink remains HOT, then heat wont flow from CPU from heatsink further, and works the other way around. Heat always flow from higher to lower bodies.
Ive read bout this kind of heat perception by touching in more than one places, and works pretty well too.

To check the extend of the truth, u can try urself if u have a digital heat sensor. Just touch the sensor for a few seconds on the heatsink tightly, and the temp raedings wont be much different from the actual CPU temps. Maximum difference of 2~3c.

@damngoodman99, make sure that you connected the fans in right direction. Side fan: blow air inside. rear fan: blow air outside.

[damngoodman999]

@ dOm1naTOr

I touched my hest sink pipes and aluminum @ load it is not at all heat it is weird my cabinet temp is 30c only but CPU temp is 50 how ??

@ desiibond

i kept so much fan in the cabinet there are 7 fans !! did u see my cabinet picture what to do with fans airflow is good


@ The Sorcerer

AMD recommends not clean the processor head with any wet clothes , acetone , isopropyl etc - they made a video on you tube just saw that only told to clean it with wipes & cotton !!

i saw in some forums all the GIGABYTE & ASUS mobo of phenom 2 940 are experiencing the same problem so what to do !!

Biostar, MSI , DFI products are showing exact temp of 940 CPU

[dOm1naTOr]

Since its running cool, go on with it.
Once theyll launch new BIOS which will fix the issue.
Is not resolved in nxt 2 months, mail the gigabyte address found on website and ask what to do. Theyll agree to replace the mobo, and go to ur dealer and say this.
htey ll sent it for RMA.

[damngoodman999]

RMA for what ?? heating issues then which mobo they change and give

[amitash]

^run the cpu at 100% load on prime95, fget about temps...if its stable for atleast 4-5hrs, then the bios is giving you wrong raedings...wait for a new bios.

link please!! Pretty interested . And is the video on amd's website. I dont why would they use youtube to put the video? Even they know mixing 2 different type of thermal and/or mixing used with new might cause some effects on thermal efficiency.

I just Ran the PRIME 95 for 5hrs , the final temp @ 100 full load is 62-64

Then immediately i played CRYSIS WARHEAD the CPU works fast !!


The system is stable - is that enough i dont need to worry about the temp ????

[dOm1naTOr]

Bingo.
its safer than home.:-P

You can look for some temperature sensing module with temperature display and some fan controllers/card readers etc on a CD ROM bay or floppy drive bay, from lynx or mediahome.

And attach the sensor on heatsink, as much close to the processor, but on heatsink.
Such bay costs bout 600~1200/-

[damngoodman999]

ya thanks Domi !!

i look forward !!

[amitash]

It looks stable...I think you can use it quite easily without worying about temps

[damngoodman999]

Thanks to u amitash !!!

How about SUNBEAM core contact freezer ??? is is better than Cooler master Hyper212 ??

[damngoodman999]

Thank you for your kindly mail and inquiry. About the issue you mentioned in your earlier mail, is there any unstable situation or other problems you have encounter with your system? Basically, if the temperature does not caused the system to crash or unstable, the temperature you measured can be acceptable.

In addition, we do not guarantee all 3rd party H/W monitor utilities will work properly with our MBs because most of the S/W does not know our H/W design and impossible optimize their S/W for our MBs. We recommend you trying to use Easytune program that we have provided in the driver CD for H/W monitoring later.

By the way, if you still concern about the temperature problem, we suggest you to add more cooling fan or system fan in your computer to help reducing the heat on your system.

This is sent by GIGABYTE support

I used the Easytune it shows my CPU is IDLE @38c , Why do many mobo donot have support for the 3rd party SW ??

[desiibond]

@damngoodman99. I think OCQ vendetta2 and vanquisher are better coolers

anyways, unless you are going to overclock, it shouldn't be an issue. Also, did you check the temperatures in easytune?

[damngoodman999]

Do i need to enable the COOL & QUIET in the Bios if i enable means the clock is downgrading & temp drops another 5 to 37c is it good to enable c&Q ???

[j1n M@tt]

first of all Core Temp and Real Temp wont work with AMD CPUs well. Then if u don't apply the thermal compound in the proper manner, it will cause heating issues.

Then since u ran the prime95 for 5hrs and no problem, I guess this is the new BIOS bug.

btw OCZ Vendetta2 and SCCF are gud...the vanquisher and Hyper212 don't do so well.

[damngoodman999]

@ j1n M@tt

Do i need to enable the cool & quiet in the bios ???

[j1n M@tt]

if it is running at stock speeds, then I don't think there is a problem in enabling C&Q in BIOS.

[damngoodman999]

Id i Overclock means than i should disable it ??

[j1n M@tt]

hmm..I dunno much abt AMD overclocking. Usually all will turn off all power saving and fan controls when overclocking. For Intel we should disable Speed step, C1E and all.

[dOm1naTOr]

it has no relation with stock speed. It can be enabled even if oced. That is even if oced, if cnq is enabled, the cpu re+aches some 1~1.Ghz when idle, and at full load it reaches the max oced clock in fraction of a sec.

enable it if u want to reduce the power bills. it reduces the overall performance by 3~5% of CPU. But the power savings is worth more than the 5% xtra performance i guess.
Enable CnQ and help make the world better.

[damngoodman999]

Ya finally the CPU accurate temp @ stock cooler

Idle = 42

Load = 48 to 51 thats charm !!
