Interesting, I've tried reseating it with arctic silver and it's still idling hot. I also added 2 fans, brought everything down a few degrees..

Idle: 54C CPU, 34C MB
Benchmark Load: 70C CPU, 35C MB

Using stock fan but I believe 61C is the max recommended temp for this processor.

I am sharing my personal experience with you. I actually own a phenom II 955 BE and was , until recently, in the same boat you're in right now. This all changed when this article was published

Use the program mentioned in this article to undervlot your CPU

The Program is called K-10Stat and it can be downloaded from this webpage

You'll also need Prime 95 or a similar program for stress testing

I found that my CPU can run at 1.15volt 24/7 stable down from 1.3 Volt. Your CPU will probably be able to run at a reduced voltage as well.Also, the CPU temperature never exceeded 58 during full prime 95 load.

I now own an aftermarket cooler but this is because my motherboard temperature was in the 57-60 range. If the CPU temperature is your only concern, the previous instructions are enough for you.

Important information about your processor:

http://products.amd.com/en-us/DesktopCPUDetail.aspx?id=401&f1=AMD+Phenom%E2%84%A2+X4&f2=&f3=&f4=512&f5=AM2%2b&f6=&f7=65nm+SOI&f8=&f9=3600&f10=False&f11=&f12=True

As you can see, the maximum recommended temperature for your CPU is 70 C not 61C

@dogman_1234: Please tell me the source of that information.

61C is the maximum temp, the one you looked at is a different product number. Mine specifically is HD9750XAGHBOX and HD9750XAJ4BGH. I'll try messing a bit with the voltage so long as it's stable, I can shave off 3C by bringing it from 1.33 to 1.23 volts. I'll bench it now and see if it's stable or not. But still it brings to question the 61 Max temp being ridiculous.

How in the world can I get this processor to run per specs? People complain about the stock fan but when reviewed the stock fan out-performs most after-market ones to my knowledge. It's loud which I don't like but I can deal with it. I have cool & quiet off and fan controls disabled. Any more advice?

product specs: http://products.amd.com/%28X%281%29S%28njbbzh55lszaiq45bc4ayuzg%29%29/pages/DesktopCPUDetail.aspx?id=397&AspxAutoDetectCookieSupport=1
 
A stock fan does not out perform most aftermarket ones, that's the most ridiculous statement I've ever heard. Not even close. Unless of course your buying some crappy $10 fan.

Yousseff has a good point, you can always reduce temps by reducing voltage, however you don't need any kind of program to do this, you just reduce the voltage in bios.

Reviews of similar fans, AVC Z7U7414001 is the stock fan with Phenom. It's not the best of course, but it ranks very well and should be very efficient.

And yes, I reduced the voltage and it is less inclined to overheat, under cpu benchmarking it will rise to 64C compared to 70+ but 61 is the limit I'm shooting for. It idles much cooler now, 45-50C instead of 60. It's not what I wanted to hear but it still works to some extent. I guess my real question is simply why does this CPU overheat out of the box? And if I RMA it will the next one in line do the same -- is this the expected quality?
 
Frostytech is a joke, don't buy into their failed testing methods.

They use the same thermal paste for every fan they test which negates any advantage a manufacturer might have with their particular paste or their particular heatsink material.

If they tested using the paste that comes with each fan, the results would be completely different.

That would be the proper way to test something. I don't care if they tested it with toothpaste, what I want to know is a side-by-side comparison between products and their cooling potential. I liked that review because it also said the decibals of each heatsink/fan, that way I can see the "bang for buck" ratio or rather the "cooling without losing my hearing" concept. Unless you can give me a good reason why the review is unreliable then I have no reason to doubt it.

From the specs you provided, your processor is the phenom 9750. I didn't know this processor had more than one revision and I am sorry for reporting any wrong information.


Back to the matter at hand, in my country, the summers some times pass 40C during daytime. and After I read the article on this site, I was able to reduce the voltages and the temperature of my processor and made it run within spec (maximum CPU temperature was 54C). I lived with the stock cooler for about a year. I only changed my chassis and cooler because the motherboard temperature was always between 50-60C. But as you mentioned before, your motherboard temperature is in the 30s so, that's nothing to worry about. So, unless you're living in a hotter place, you should be able to get your processor to run within spec.

Please note that I needed to run my system in boost mode from AMD Overdrive software in order for K-10Stat to work properly (It is the green button in the top right corner of the AOD window). Otherwise, the processor will totally neglect it.But that might not be the case with you, just thought this tip might be able to help you.

Turning Cool'n'Quiet off might be an alternative to boost mode but I didn't try it. So you should try using K-10 Stat without boost mode first.


Sorry for the long reply.

I didn't realize there was two different 9750 specs either until I read the article you posted. I'm under-volting via Ai Booster (Asus product) to test stability then manually changing in the BIOS. I brought it down to 1.1 and it's working like a charm now. Still frustrated about it all, but a bit relieved. Thanks for all the info and help on this.
