this is my first AMD Cpu
i've noticed that the AMD's Achilles heel is it's temp
so i'm a bit concerned bout it

then i read that voltages can influence temps too

i have opened my cabinet case side
and the readings are as below (taken ~5 mins after pc startup)

according to speedfan

temp2 -45c
gpu -34c
temp1 -36c
hdo -31c
core -48c

vcore1 -1.39v
vcore2 -1.46v
+3.3v -3.31v
+5v -5.05v
+12v -12.42v
-12v -0.06v
-5v -1.63v
+5v -3.63v
vbat -3.10v
hd) -93%

fan1 -13rpm
fan2 -3000rpm
fan3 -0rpm
fan1 -3169rpm

the climate acc to today's newspaper is max-31c and min-21c

i'm now currently in a pretty hot place (INDIA)

when gaming i focus the room fan to side open part of the cabinet.....and after playing gta4, i checked the temp it was ~60c
if i don't switch on the room fan, then the temp easily crosses 65c

and AMD has it's limit stated at 60-70c

i don't plan to overclock
and have no plans to buy coolers and stuff


my specs

CPU- AMD Phenom II X4 965 Processor BE 3.4ghz
GPU- NVIDIA GeForce GTX 560
MOBO- gigabyte GA-78LMT-S2P
ram- 4gb
Hard disk- 1tb
PSU- http://www.game-debate.com/psu/index.php?ps_id=357&psu=...

Your CPU is running extremely hot even if your ambients are a little high. You should be seeing load temperatures of around 50-55C with the stock cooler.

There are a few things you could try -

1) You can safely run your CPU with 1.3V, I suggest lowering your voltage little by little inside your BIOS to see how low you can get. This will ultimately reduce your heat output and save a little bit of energy ;) 

2) Replace the Heatsink Fan/Thermal compound. There is a chance that the Thermal Compound is all dried up (especially if the CPU install is quite old) and needs replacing. A loose heatsink may also be the factor in your temperatures.

However, generally speaking, AMD CPU's are under-rated for heat. They can take over what AMD recommends, however, since AMD CPU's run so cool as is, I generally try to keep them under 60C at load.

To be honest, at stock his 965 probably wont be stable at 1.3v. Stock on them are 1.35 to 1.38v. Some phenom chips I played around with will not boot at 1.3 or lower, some will. Also the max safe temp on the 965 is 62c, 70c is the shut off point in the CPU, Some mobos will over ride that and shut down before it hits 65c.

it would help if you say the correct voltage....i'm new to adjusting voltages

1>>>Thanks for the reply, but why do i need to decrease the voltage gradually and not directly to 1.3v?
2>>>does 6-8months qualify(coz that's when i last applied it)
3>>>what are the ill-effects with playing around voltages? (i have never done this)

I have ran my X4 955 in my HTPC @ 3.2Ghz @1.32v without any stability issues.

You're very welcome :) 

1) Every chip is different, thus each chip will require different voltages. Decreasing your voltage to what people recommend right from the get-go may not be the best thing to do :)  It may be too little voltage causing instability and crashes, or your CPU may still be capable of going down lower.

2) 6-8 months seems about right for swapping out your thermal compound. I would recommend doing that ASAP and see if you can get some instant results regarding temperatures.

3) As far as I'm concerned, there are no ill effects in regards of lowering your voltage, however, there are some serious ill effects if you over-volt your CPU. For example, let's say you're overclocking, if you give you chip too much voltage, there's a chance you may fry your CPU.

Since you're not overclocking, I will not get into this topic any further :)

Hi,

I've installed 3 AMD CPU's PII x4 965be, FX4100 & FX8150 currently in my main gaming rig...all 3 had Temp's of 44-46C. The FX8150 is in a Antec900 case with 5 case fans. My new portable build w/965be has 3 case fans, all with stock Heatsinks. The PII x4 965be voltage 1.38

I would suggest you get AMD Overdrive to monitor the temps.
