Hello. I have a pc with these specs
thermaltake toughpower 650w
amd phenom x4 9950 be (aftermarket cooler gamma archer)
gigabyte ma780g-ud3h
5gb ram

the strange problem now. I am at idle 45c. When i plug in the usb wifi adapter and pc connects to the internet, it goes to 60-65c in 5 seconds!!! I tested another wifi adapter. The same. I changed os from 8.1 to 7, the same again. The thermal paste is new and is the arctic mx-4. I reseat the cooler, nothing. Also i am clean with viruses and cpu use is at 0-1% at idle

i am not overclocking and the bios is the latest version. I have this problem somewhere 1-2 years now. I didnt have this problem earlier, even with the stock cooler. Someone told me that cpu is dying.

OK. Didn't know you had access to another CPU. I would have suggested that first off. But now you know the CPU is failing. If you want to hang on to the aging platform, I see the board can support "newer" Phenom II X4s and X6s with the correct BIOS. If you can still find one. Maybe on ebay... used.

In other words, for my cpu, the speccy program and the hwmonitor show the margin temps. Wow i didn't know that the link is very useful. Thank you very very very much for your help clutchc. :) So, my pc is ok. Also, you said this cooler is for 95w. I will check this to change the cooler. Thank you again 😀

Yes it was online when i upload the overdrive screenshot. The only thing that i didn't test is to connect on internet via ethernet cable and not wifi. I will test it and i will tell sou the results :)

Wait a minute! Back up! I just noticed that AoD isn't referring to that temp as "thermal margin" as it should. It is calling it "temp". What version of AoD are you using?

That makes more sense. Although I'm seeing that the newer version of AoD is not going to work with a CPU from that era. The crazy -121 number simply means it isn't working with the algorithm used in that old CPU. You have to use the older version of AoD from earlier. The one for the Dragon era.

But, that changes everything...
Using the older version of AoD (which reads actual temp rather than thermal margin), 69C at idle is apparently the actual temp of the cores. Very bad if at idle. I guess I led you astray. It's been awhile since I worked with an AMD processor that old. I forgot they don't work the same as the later ones. I have an older Phenom X3 8650 that shows the same crazy temp number with the newer AoD.

Bottom line... You need to change the cooler if that is still happening with the questionable wifi adapter removed.

Yes i know is very bad. The weird is that the problem is only with all the adapters that i have. I don't have problematic adapter. It does the same thing with all. When i am connected with ethernet i don't have temps issues. On idle is 47-48c and and on load 59c max. So, i don't think that the cooler is the problem. I tested with tx3 coolermaster and i had the same results with wireless connected. I did a clean install of windows 7 AND windows 8.1 with no results. Something else is the problem.

Yes, you seem to have an issue somehow related to USB adapters. Is it just USB adapters that raise the CPU temp?
I guess you stumped me on this one. Unless somehow loading up the USB causes a bogus CPU temp reading. Is there a noticeable difference in the way the cooler feels when the adapters are in use? Try to lay your finger on the side of the cooler. I'm wondering if it is possible the temp is actually not rising, just the readout is changing.

Yes this is happening only with usb wifi adapters. When i connect usb flash drives, everything is fine. For the cooler, unfurtunately i thing the temps are rising. I didn't lay my finger but when i connect the adapter the cooler make more noise than before. The rpms are bigger. So the high temps are true. I don't think that the temps sensor is problematic.

True. If the fan increases in RPM, either the CPU is indeed getting warmer, or the m/b BIOS thinks the CPU is getting warmer. That is why I was hoping you could verify by touch if the cooler's heat sink actually felt warmer when the adapter was plugged in.

Short of a virus or some kind of malware causing this, I must assume the older, slower CPU just works harder to do the simple task of USB connectivity and file transfer. If you have C&Q active in BIOS and the CPU is at low power state when idle, it will switch to full power, possibly all cores, when the USB system is awaken.

Run HWinfo and watch the CPU Usage and the Max CPU/Thread Usage when you go from idle to plugging in the USB device. http://www.hwinfo.com/

On a side note, that Phenom x4 9950 Black Edition and your motherboard were a nice combo back in their day. Top of the line. Overclocked? Was that the 140W or 125W version of that CPU?
I just noticed there was a 125W version also produced.

Malware or virus after 2 clean installs of windows? It's a little bit impossible i think. The c&q in bios is disable and i am with the latest bios. I run the hwinfo, when i connect the adapter the cpu usage of all the 4 cores is 1-2-3%. Where i can see the W of the cpu?

I forgot you did a clean install of Win.
If HWinfo doesn't show the wattage of the CPU, it might not be available for that generation. You can get a rough estimate by using one of these: https://www.amazon.com/P3-P4400-Electricity-Usage-Monitor/dp/B00009MDBU

It will read total wattage of the entire system when set to do so. Then you can see the difference between idle and once the USB device is plugged in. It won't be totally accurate because it is reading the AC line side of the PSU, not the DC load side. But you can get a pretty close idea.

Oh i found it on hwinfo. Is 125w. Also i did another test. I check the temps with linux (lubuntu). Without the adapter is 48c, with the adapter on goes to 57c and in windows 65-66. So, its not windows problem. This is happening also with linux.

I'm beginning to think the person that told you the CPU was wearing out (or dying) may have been right. It seems to overheat at the slightest usage.

What happens when you really stress the CPU? Run something that takes it to 100% usage like Intel Burn Test. http://www.majorgeeks.com/files/details/intelburntest.html

Watch temps closely. If you see the temps go above 61C for any length of time, stop the test. I'm assuming your Phenom is this one since you said it is the 125W version and not the 140W version.
http://
This may not be a very practical test since your 95W cooler is too small for the 125W CPU. But it would be interesting to know how fast it reaches unsafe temps.

Yes yes this is the cpu. So, i will remove the adapter to make the cpu goes to 48c idle, and i will make the stress test to see the temps. Yes i know the cooler is too small.

Ok i did it. From 48c, when i hit start, after 5-10 seconds it goes to 80c!! What the f***. So, maybe dead cpu right? Can i ask you something. Is it possible to have a problem to my motherboard?

At this point, I'm open to anything. It's hard top be objective from this far away from the problem. But that is why I was wondering if the cooler was actually feeling noticeably warmer when the temp reading increased. Not sure if the board is sending incorrect info, if the CPU is, or if one or more cores is dying and that is the one raising the temps. AMD doesn't have individual sensors for each core. One CPU temp represents all cores.

If the CPU is actually getting that hot, it will eventually either throttle its speed back or cook itself to death. Keep AoD open and watch the CPU usage graph. Also watch the temp display. Run an app or use a USB device to get the temps back up again. When (or before) the temp gets into the 80C range, I would expect the clock speed to drop drastically... throttle.
