AMD FX 8350 overheating when working at "full load" - Page 2

post #11 of 21

I honestly do not think the GPU is the problem as when it sits at idle it is around 24 degrees ceslsius. (I have an ASUS GTX660-DC2O-2GD5 - GPU)

I do think that the air flow in the case itself might not be good and installing a second cpu fan maybe blowing fresh air into the cooling unit and then having cpu fan 1 sucking it out again might be an idea.
Edit: Included a picture of case layout.

Getting cool air to motherboard / bottom sides of cooler where fins end will definitely help. thumb.gif

As for GPU at idle being 25c, that's 3-5c warmer than room.. and it that's the temp of air going into CPU than lowering it that 3-5c lowers CPU temp the same 3-5c. And that's if GPU is idling when you are stressing CPU. If GPU is under load too than it's putting out as much heat as CPU. (GPU rated 150w; CPU is 125w) That is 25w hotter under heavy load than cpu.. an is why it has a cooler with 5 pipes.. your CPU cooler only has 4. wink.gif

This is the GPu's temperature when working at full load.

I'll see if I can get some fresh air into the cpu by installing another fan. But for now that'll have to wait as I do not have one lying around.

GPU is nice and cool.

If you are leaving your case open for now you could reverse the rear exhaust fan or take it loose to use.. maybe set it on top over bent above cooler.

I have a feeling you need a better cooler. If you are not going to overclock you could use something like Thermalright True Spirit 120 or 120M(not as tall). Here in UK they are about £25.00. From there up to Phanteks PH-TC14PE, Noctua NH-D14, NH-U14S, Silver Arrow SB-E, to name a few of the top coolers.

Stock coolers generally are not up to full time 100% load. A good, cheap step up is the Cooler Master Hyper 212 EVO. They go for around $30 US.

For around $50 US, the TPC 812 should be very effective. I have a Hyper 612 PWM on my 8350. It would not really be necessary except that we don't air condition all the time, and Chicago summers can get pretty hot. The other thing is that my system runs at 100% usage all the time, including two GPUs doing heavy number crunching. That puts some exceptional demands on cooling, but it would take a double wide radiator to equal the performance. On the other hand, with the huge air cooler, I would not want to be moving it all the time because of stress on the motherboard. The Hyper 212 is considerably lighter.

EDIT: That GTX 660 is more power efficient than the GTX 460 and GTX 570 I run, too. I'm doing well to keep the 460 around 64 C and the 570 under 70 C. The CPU gets up to around 55 C.

Ok so I am sorry for my late response.

Due to the fact that the fx 8350 is such a strong processor and I might want to OC it in the future. I bought the Noctua nh d14 CPU cooler. (primary reason: It's quiet.... I'm getting very very VERY annoyed with this jet engine that's running atm.) I'll let you guys know how it turns out when I have it all working and tested. Thanks for the advice!

(and yes, it is a pretty expensive cooler. But better pay 20 more to have something which is a little more silent than pay to pay 20 less and have something which I still don't find acceptable.

Let me know how that Noctua cooler works for you. I'm currently running a 212 Evo on my 8350 @ 4.5G and less than 2 minutes into an IBT it's at 62c. It idles at 32. I'm debating between the Noctua or the Phanteks PH-TC14PE.

Allright so currently this MASSIVE Noctua nh-d14 is on my cpu. (not making any noise at all!!) In the meanwhile I also received a new Mobo as the prev one suddenly stopped working....

BUT: Still my cpu goes up up and away in temperature when I run prim95. I have ZERO control of the fans, I'm starting to think there could be something wrong with the temperature measurements or so?

2 days ago I converted a movie from .avi to .mp4. It took me 5 mins to end up with a CPU temperature of 80 degrees celsius. That can't possibly be good can it?

also, I changed cases. Now have a Cooler master HAF 922 running with a total of 4 case fans(2x 20 cm, 2x 14 cm). So I don't understand why it overheats.
post #19 of 21
I have the same case as you, HAF 922 with 3 of the 20cm fans and 3 additional 14cm. I have the 20cm fans plugged into molex connectors so they are constantly at full rpms and still quiet. The 14cm fans fluctuate with the cpu temp. 80c seems way to high whilst converting a video file. I converted several files to mkv on Thursday on a batch job. It took about 4 hours constantly running and the cpu temp never went above 55c at stock speed of 4g. 80c is way way to hot!

What programs are you using to monitor CPU temps? I use openhardware monitor and HWmonitor

I'd try reapplying thermal paste and re seating your cooler. Also you may want to check to see if there are any BIOS updates for your Mobo.

... I re-applied my cpu cooler 5 times now with 3 different cooling pastes. My Mobo is updated to the last version... I use asrock extreme tuning utility and speedfan to measure temps. They both say the same. I've done everything I could think about but monitor the temperature with a physical device. ( as I don't have one). Could it be the sensors on my Mobo are either broken or not displaying the right values?

edit: do not EVER do that again to me amd.. By default, the "AMD turbo core technoology" is set to enable in bios. which causes your cpu to be overclocked.

I however; had no clue that this was on, and just declocked my cpu be decreasing the speed which it runs at in the AXTU. I now set the speeds to default in AXTU and disabled AMD turbo core technology and now... believe it or not. My temperate jump between 45 and 50 when running at full speed for 20 mins. I guess the turbo core technology is causing the extra heat?
