AMD A8-3850. Temps are HIGH! - Page 2

post #11 of 24
I just joined after finding this thread on a web search. There is a cool n quiet option in my MSI's FM1 bios. I am also experiencing idle temps of 62-66 degrees. Have tried stock and aftermarket coolers and three types of thermal paste, to no avail !

Anyone got any updates to this situ ? The reviews I read before buying waxed on about these chips running 'so cool'. Which isn't the case !

"Smaller the process, bigger the current leak", as a reminder. Also the heat density should be higher, all of these contribute.

What is the Tj. Max for Llano?

Maybe it can handle that heat wink.gif

I know the mobile ones have a Tj. Max of 115*C

I have MSI mb with an A8-3850, using a seperate graphics card, It now runs at idle around 27 to 30 degrees C. voltage is 1.143 V.

Had a bunch of problems with this set up until I ran the July 2011 BIOS update from MSI, since then its been running great.
I run auto settings in the bios, however I have over clocked it from 2.89 to 3.2 ghz, still tever ran above 34 degrees on the CPU.

My case does not have a fan, I am running 4 x 4GB DDR3 sticks, 3 HDD's and the seperate GPU and the system temps stay between 32 and 35 degrees C. I figure if I want to run it overclocked safely I will need to install a case fan.

My recommendation is run the bios update, if it is still hot, spend $40 on a decent graphics card and you will be good to go.

That says my CPU has a max temp of 90. I don't believe that for a second. It should be around 62.

If your cpu idles at 27-32 and your graphics card idles at 39-50, and you put them on one cheap stock cooler, you can understand why temps are so high.

Undervolt. A lot.

If I can validate my 45nm Phenom II at 4.3 GHz with 1.3v, then you can definitely get your 32nm A8 at whatever speed you have it at (can't be more than like 3.7 right?) 24/7 stable with less... unless you have a terrible chip.

Stock can undervolt to under 1.25.
