Overheated Phenom II 955 BE

brad1138 · Jun 5, 2013

I am rebuilding all of my families computers, upgrading them to faster more modern systems. I gave my son my P II 955BE, MoBo & Mem, but I wanted to keep the high end cooler so I ordered a new one for my son. Nothing special, but should be better than the old stock coolers I had laying around.

Unfortunately I didn't notice it was only rated for 95 watts and the 955BE is 125w. When I ran IBT the CPU got to 75 Celsius and I was being stupid and not watching, so it probably ran there for up to 1-2 minutes. It's max temp is 70C, should I be worried I fried something?

Thanks

as long as it still works, you're prly fine. just get a decent cooler for it now

CM Hyper 212 coolers are good and cheap

I have this cooler http://www.newegg.com/Product/Product.aspx?Item=N82E16835233014 that I like and didn't want to give up. It wasn't OCed at all when it hit 75C. I will probably get him a higher end one cooler so he can play with OCing some. The CM Hyper 212 is 120mm, I want to go with a 92mm, they are easier to fit into all cases. My sons case has a sidemounted fan that would likely hit the 120.

You probably put too much thermal paste on the cpu/heatsink, or the cooler isn't mounted completely even. The thermal paste should be a tiny bit more than a clouded surface and no more. Too much paste will insulate, instead of dissipating the heat.

I have had both issues back when I first started bulding PC's, too much thermal paste, and an uneven placement of the cpu cooler . Both caused the heat to go to shutdown temps or very close, so I would look into those things first before you buy anything else.

You also stated that the cpu is 125w and the board is only rated for 95w. The cpu most likely isn't properly supported by that board, but if you intend to keep using it I suggest lowering the clock speed and v-core so not to burn anything out if it has a catastrophic failure(which could still happen, btw). There may also be a boost feature kicking in that is driving the cpu up another few 100mhz which would also drive up it's power consumption(above 125w). I would look for the settings in your bios to turn off that option if it's in there. Are you trying to overclock as well? If so you should stop right away before you kill something. lol.

My X6 1090T idles at low 20's and gets around the high 40's while gaming. I believe the internal shutdown temperature built into the phII's is 63 degrees.

I was also thinking it could be an issue with the thermal compound. More isn't "more" when it comes to Thermal compound. The line method is best in my opinion. Check out the video in the link.

I have been building computers for about 15 years, but you might be right about too much paste. I have always used very little and it has worked great. Before giving the 955 to my son I ran it at 4GHz for 2 years (stock is 3.2), solid as a rock. I decided to look up how much past to use on YouTube, just to check that I was doing it right. I found this video http://www.youtube.com/watch?annotation_id=annotation_331548&feature=iv&src_vid=o7rPqCvCt0g&v=I3gx6c62D7I which showed using more than I ever have. I should have searched for additional videos, but I followed that videos instructions.

I am going to give my son my cooler and get a new one for me a bit later.

When I said 95 watt I was talking about the cooler, not the MoBo.

Well it is starting to warm up here now, but im still in the mid 20's. I could get it lower if I open a window. http://i1291.photobucket.com/albums/b554/Sincreator/IDLE6cores_zpsdec23bf7.png

Want to see as low as I can go, and what it hits under load? I can do that too. Here is after 3 loops of the cpu benchmark in 3dmark06(both tests): http://i1291.photobucket.com/albums/b554/Sincreator/idleandload_zps4ed0fb1f.jpg Games don't push the cpu up that high...

Maybe so. I'm just showing you what I see... I came in here to try to help the guy out. Your only advice in this thread is for him to buy a better cooler. The XIGMATEK coolers are great coolers, so why would he need to spend money on something different? Then you proceed to call me out. Troll much?

brad1138 · Jun 5, 2013

A bit off topic, but I usually look at the CPU temp is BIOS, then check HWMonitor to see which of the "temperatures" (not CPU temp) is closest (I turn off cool and quiet in windows settings for this). It is common, with AMD, for the reported temp from the CPU to be 10C or so less. Then I run IBT and see if the CPU temp and the identified temp in "temperatures" raise in tandem. If they do, I use that to adjust the offset in Coretemp.

Not as accurate as a laser probe, but as good as you can get w/o one.

brad1138 :

I just restarted to check out what you were saying. In my bios the temp is 8 degrees warmer than what Hardware monitor reports for my idle temp. I always thought that was because of my case fans, and cpu cooler starting off at low speeds though until windows was loaded.

I may have to try out your method later.

Nothing wrong with Xigmatek, but you have to have a cooler that dissipate the heat for your CPU properly. A 95W cooler isn't designed to work with a 125W CPU. Lowering the CPU voltage and clockspeed isn't a realistic solution. There isn't much room to undervolt Daneb CPUs. The only logical solution is to get a better cooler, which the OP just said he was going to do.

Reading the customer reviews for his current cooler tells me that this cooler should work just fine for 95w/125w cpus. Well there seems to be an awful lot of happy 955/965 users that wrote reviews anyways. I didn't even know there was such thing as a 95w/125w cooler. I couldn't find anything in the specs that indicate a max cpu wattage.... http://www.xigmatek.com/product.php?productid=17&type=feature

What a difference a good cooler makes. I gave my XIGMATEK to my son and put it in, w/less paste

. I ran IBT and it peaked at 47C after 10 runs. Then we OCed it to 3.960 GHZ (220x18) and ran IBT and it peaked at 55C. It had been a couple years since I built the 955 system and had forgotten how well the XIGMATEK kept things cool.

Thanks for the replies.

brad1138 · Jun 5, 2013

I knew I shouldn't have given my son my cooler... the 964 is NLA, there is a 963, but it isn't as good. Anyone have recommendations on 92mm coolers? It think this review http://www.frostytech.com/articleview.cfm?articleid=2401&page=5 is where I got my info for buying the 964 originally. I think it is(was) the best 92mm cooler available, doing better than many 120mm setups. I am going to look for another one on ebay.

sincreator · Jun 5, 2013

brad1138 :

Maybe this one: http://www.newegg.com/Product/Product.aspx?Item=N82E16835233025 Probably pretty similar to the one you just gave your son.

"Low 20s huh?

Something (common sense) tells me that isn't possible to achieve room temperature on an old CNPS9700... Unless...... http://www.youtube.com/watch?v=mDYNuD4CwlI "

My FX 8120 reports 15c idle. Cooler than room temperature... My case is refrigerated of course... (joking) I do believe in magic BTW.
