Opteron 170 is hot, even with new heatsink!

Hi everyone, im new here.. anyway

I received my SI 120 today, as the stock heatpipe cooler didnt cut it for me.

So i slapped it on tonight, with a YS-tech 120mm fan that pushes 125CFM at 40DB. I instantly ran dual primes for a few mins to check the temps, and all temps were not very good. The cpu rose to about 56-58c in a fairly short amount of time, also the PWM ic temp was pretty high.. getting into the 60c's range.. Chipset was around 50 i think.. maybe a little higher, anyway.. i increased cpu voltage to just 1.4v and tried a little overclocking and the temp shot way over 60c! it must have been about 65-68c easily.

anyone know what the problem is here? i have a high CFM fan pointing right at the cooler, and i even will need to control that a little soon as its a bit too loud for me by about 5-10DB's. I made sure the hs was making optimal contact to the cpu before i turned it on.

Thanks

What's your ambient temps?
What motherboard are u using?
Have you confirmed the temps the motherboard is reporting with a real temp probe?
Have you actually reseated the HSF again just to make sure that it is in good contact?

What's your idle temperature? Some motherboards have problems reading the temperatures off Opteron, so you may need a bios upgrade.

What is your clock speed and voltage. Leave the side of the case off and see what the temps are then.

my ambient temp is about 20-23c, i am using a dfi sli-d mobo. I have also checked bios for temps they are hot. I have updated my bios already when i got the chip, i put little bits of thermal paste on the cpu it smudged in and evened out when i put the hs on the cpu and rotated it a bit before i clipped it in place. so anyone have a good idea what i can do next?. cpu voltage is only 1.4v side of my case is already off btw

download a program call "central brain identifier". get the latest version. click on > Mobility and there will be a dropdown menu- click> P-States.

You will see a thermal offset on the bottom right....... if it is positive, ie- +6C, then you can subtract that amount from your displayed temp. If it is -6C then you add that to your displayed temp. CBI detects the CPU's internal temperature and gives an offset based on your mobo's monitoring temp.

With different CPU's in my rig it ranges anywhere from -1C to +6C. The latest 148 I have reads +6C, which means it is actually 6C less than MBM5 temps.

How reliable is this? Why would the mobo not report the temp based on the same process used by CBID if it is more accurate/reliable? Just curious.

If you are using arctic silver 5 you put it on wrong
"i put little bits of thermal paste on the cpu it smudged in and evened out "
That is wrong.

well even if it is wrong it looked ok to me, besides how the hell can temps raise so much if its wrong? ive always done it this way.

and i downloaded that CBI it says my thermal offset is 3c, so this doesnt get me anywhere and im still at square 1.

temps were terrible with the STOCK hs & fan, and the thermal stuff was already applied to the bottom of that.. and its no better, or the same with this heatsink and a fan that gives a lot more CFM.

We have Dual opteron 270's on Tyan K8WE boards here at work, and apparently there is a bios temp reading problem, cause my temps are reading 66C at idle, and ~75C under load, but I touch the heatsink and it's barely warm. It sucks, because the fans are on turbo because it thinks the chips are buring up. Aparently this is a known problem with this board, maybe yours has a similar problem.
