Hey there, i just built my first rig! i am wondering about temps, i have installed the hyper 212 EVO cpu cooler on a amd 965 BE, i decided to overclock it to 4Ghz, i did so successfully, im wondering about temps,.. my room temp is 22 degrees, my case temp on my probe is 25degrees on idle, my cpu idle is 30-32 degrees (4ghz) and 57 on full load (4ghz) are these good temps? i used the coolermaster thermal paste that came with my cooler so i was wondering if it was not doing its job so well..

So my question, are my temps fine? :)

I'd strive to lower them but theres nothing bad about them, maybe look at your cases airflow and see if you can alter/add fans to help out

my case has 2 outtake (top and back) 2 intake (front and side) all 120mm fans, i could add another outake at the top, another intake at the side and a intake at the bottom, either 140mm or 120mm, or even add another fan to my hyper 212

I would say your idle temp is fine but 57c under load is a little high. Add the fans and try to get your load temps down to 50-52c.

Adding the second fan to the 212 will be the most beneficial move to drop that load temp, I'd do that first and then consider any others, I assumed (Shouldn't have sorry) you had the push/pull set up already,

what fan would you recommend as the second one? i cant find the hyper 212 evo fan anywhere. also, seeing as all my fan slots on my motherboard are taken up, how would i set it up?

Look under CM fans -- do you still have the bracket?

Your temps are not bad, but without knowing your volts it is hard to help you. AMD max temp spec is 60c+

AMD processors each have varying 'volt walls' -- every chip is different. Your goal should be to find the volt wall for your chip.

As an example, at 4GHz, you may be pushing 1.425v with temps at 57c. You may well be capable of running 3.8GHz 1.375v 46c

It gets to a point where you have to run up the volts to gain little practical clock speed. Driving up the volts simply drives your temps higher for few GHZ in return.

i still have the CM bracket

when i overclocked, all i simply did was make the multiplier from 16x to 20x, still running stock everything else, so my cpu at 3.8 say with lower volts and lower temps wont be any much slower that 4ghz at higher volts and temps?

You will tell little difference in 200MHz.

You may see significant changes in temps, however, with the drop in volts.

If your voltage settings are on 'Auto' you will need to set them manually.

CPU RATIO -auto

CPU/NB frequency -auto

CPU Voltage-auto

CPU/NB voltage-auto

CPU VDDA voltage-auto

sorry to sound a newbie, but im not sure what the NB is on the end of them and what to set those to.

Check out the BE oveclocking guide up top, it will help you understand some of the terms used,
but if voltage is on auto then yes, that is definitely pumping up your temps, you should find the right voltage manually and should lose some degree's just from that

So, your saying to undervolt my cpu to a stable state, and then overclock it to about 3.8ghz ?

Its not undervolting, its finding the best setting,
the mobo may automatically set the Cpu voltage higher than is necessary for it to run efficiently, like 1.45v when you can actually run it at 1.425,
its for you to finetune and find the spot where it has enough power to run, but not too much that it creates an excess of waste heat,
you should be able to get 4GHz on that chip with some fiddling, just remember to never exceed the Amd spec for maximum voltage, not nominal, maximum, it should be around 1.55v but check amd's site for your chip

In my bios i cant find a set thing that allows me to set my voltage,

There is

CPU ratio

CPU/NB FREQ

CPU over voltage (is that it?)

VDDNB Over voltage calibration

Loadline calibration

HT link speed

HT over voltage

i found it under hardware monitor..

My VCORE voltage is 1.428V...

should i try lowering it bit by bit? how will i know if it works or not?

You want to find the lowest setting it will boot at, try 1.325 or thereabouts to begin with,
if it won't boot into windows, up it one, then try again, and so on until you can boot successfully,
its all in the Oc guide I mentioned earlier, just takes some time to find whats right for your chip, even the next one off the wafer will behave differently so every chip is unique in that sense,
its for you to tune yours as best you can

MY only problem is that i cant find anywhere allowing me to change my VCORE, it will let me change overvoltage...

my motherboard is a ASUS M5A78L-M/USB3 version 0801
April 15, 2012 3:14:52 PM

hmm.. i put a pea-sized dot of thermal paste on my cpu, i reckon thats fine, 57C is at 100% load for 4 hours.. it would never get that high in anything but stress tests..
April 15, 2012 3:25:26 PM

i do not have C1E and CnQ enabled.. my ambient temp is about 21C, when it boots into windows at 4Ghz and idles at about 30-32C

April 15, 2012 3:33:03 PM

it boots, on idle it seems to work fine..
April 15, 2012 3:52:45 PM

well, i just tranfered a 20gb file, with loads of programs open, it didnt go above 37C....

April 15, 2012 4:05:21 PM

i think the reason for the higher temps in the beginning was that the thermal compound didnt.. 'bed in'? ive heard the temps get better the more you let the pc run, thanks alot though :)  so CnQ wont affect my OC when actually needing it cause people have said to disable it for that reason.
April 15, 2012 4:14:54 PM

yeah, im stressing the cpu to 100% and i hit 53C so far... its been 15mins :) 
April 15, 2012 4:21:49 PM

thanks for your help everyone!
April 15, 2012 4:32:56 PM

will do.
April 16, 2012 10:20:12 PM

Just a quick question...
im running my cpu at about 90% load, 100% on 2 cores and about 75% on the others @4GHZ and idle is now 27C...

The MAX temp ive seen is 39C

HOW?! as this is nearly full load with prime...

It's magic . . .

Really. What are your current volts?

AMD processors typically have a volt wall where more juice adds little clock speed --- more volts just adds heat.

Reducing volts will drop the top end marginally, but greatly increase thermal efficiency. I'm not surprised at your temps (at least, based upon my experience) as 40c at load (+/- 10%) is consistently the 'sweet spot' for me.

I can get a decent OC, and with C&Q enabled, generally run .9v-1.35v with NB volts around 1.2v

For each 10% in speed you increase the speed of the IMC/NB, memory bandwidth is increased 3-4% and latency is reduced 3-4%. From stock 2000MHz to 2400-2500MHz should be a 'slam dunk' near stock volts.

It makes quite a difference in gaming and memory intensive applications.

Stock volts.. i couldnt find anywhere to change them in the bios..
What i did to find my temp was running prime on 2 cores 100% and transfer a 5gb file and have a few things open, so about 85-90% load at 100% ill probably get 42C.. i dont know why prime 95 only uses 2 of my core at full throttle but oh well..

really happy with my temps as my notebook is at 63C just web browsing :lol:
