AMD 8350 + Stock Cooler

girogalllas · May 12, 2013

Hello I recently purchased an AMD 8350 and an asus sabertooth 990fx and I am pretty sure that I followed correctly the instructions on placing the stock cpu cooler on the chip... i mean its not rocket science... I even cleaned it and reapplied again thermal paste and still i am having a temp problem.
My problem is that now that I am typing this message while my cpu usage is under 5%, my stock fan runs at about 4500rpm and my temp is 47C.
Yes I am going to change my cooler as soon as I can, but is it somehow possible the cpu might overheat? Is it 100% a cpu cooler's fault?

Most people who build there own systems go for an after market cooler because they have a larger surface area than the stock cooler that comes with most Amd cpu`s. If you get a new one you will the temps drop maybe 12c.

The stock cooler should be fine for a bit, and should do the job for a while, but by all means get an after market one.

Yes but are these indications normal? My fan sounds like a nuclear factory

Miks1890 · May 12, 2013

Well I haven't seen a FX-8350 but the fan shouldn't spin at full speed at idle and at 47C. It should be at lower temps at idle and the fan shouldn't spin so fast... 3 options:
1.You have badly applied the heatsink
2.The cooler is faulty
3.The chip is faulty
What program did you use to measure temps? Try using temp gun to see how hot the heatsink is...

4. cpu fan is plugged into the wrong spot

Miks1890 :

As I said before, although I never used a AM3+ socket before, I never had problems with installing a cooler. If the chip was faulty wouldn't it also produce some errors or something other than just overheating? As for the programs I used is the AI SUITE II and CPUID. I try to keep my expenses at minimum, my next buy is going to be an aftermarket cooler to dismiss the faulty cooler. Time will tell I guess.

spartansociety :

if the fan was plugged in the wrong spot wouldn't the temps be low at full speed? Don't you think?

spartansociety · May 13, 2013

you sure 4500 is not top speed? I would hate to hear a CPU fan going faster ! My hyper evo 212 is doing 800 atm and about 2000 under a lengthy load. I have never owned a 8350 but 40's for idle while fan is at top speed seems reasonable to me, depending on ambient temperature of the room, the case, the temp software etc etc. Have you checked in the motherboard manual to make sure the fan is plugged into the correct fan connector? Also, have you set the fans to run via temp in the BIOS ?

Shaun o · May 14, 2013

Amd Cooler and fans have a high rotation speed, due to the reason of the smaller surface area of the cooler.
In answer to the question the Cpu should be ok up to about 70c or more.
The larger the fan on a cooler the slower it can spin but pushes the same amount of air through the cooler.
I have a Cooler that is twice the size of an Amd stock cooler and it has a 120mm fan on it running at 800 rpm.
It should be ok for now.

spartansociety · May 14, 2013

so whats the stock speed for a 8350 fan ?

I have the same CPU and the stock heat sink is the problem, Get a water cooler and at max temps will be closer to 26C when it's running at max fan speed's,
I have heard that no matter what board you have that CPU will over heat and if playing a game your system will shut down when it get's to it's max temps ( some will say to change the max temps in the bios but this can break the motherboard when it get's to hot it starts to smoke and when a CPU smoke's well I don't need to finish that)

I am looking for the same thinkg for a fix till I get my water cooler back some time in the next week or so, I've un-installing it and re-installed it that many times that I can take it out clean it and put it back in, In less than 5 mins, Think it's got to be close to a world record for installing a Water cooler for a CPU,

Your temperature is running high even for stock.

I bought the 8350 (removed the heatsink 4 times --degrading the paste application a bit-- as I struggled with installation of the retention bar) recently and my idle temp is 41 C at 30 percent fan speed (which I raised to 40+ percent for idle) or about 2227 RPMs.

This is about 5 degrees higher than my stock i7 860 and so I will soon get a new HSF and paste. I haven't run tests or put a heavy load on the CPU given my fear of inadequate thermal paste distribution. [Edit] FWIW, I"m playing Drakensang and the temps are mid 40s-50s.

I have 3 stock 120mm fans in my inexpensive Rosewill case, decent air flow and have paired the CPU with an Asus M5A97 (970 technology). That might account for some difference.

4500 RPM would be top speed, my top speed is 4354 under my current fan profile.

I think I would rule out the potential problems Miks mentioned as well as your case airflow in the remote chance you have a faulty chip and need to return it. You'll want to remedy this per your warranty terms.

I was told on good authority that the 8350 heatsink was better than most AMD F3+ chips and I believe it is. I don't overclock (and too am on a budget) such is why I didn't go aftermarket...but it's still a bit too hot for my taste.

P.S. Most gamer comments I've read seem to be quite positive about the hyper evo 212 with this CPU -- at least with the Asus mobo. I don't think water cooling is needed unless you're running under extreme conditions, which I presume you are not given you went stock.

ETA: Something quite odd to me is that the 8350, at least in my set up, seems to not be very responsive to fan speed, whether it runs at 40% or 70%. I can't wait to test it under load, but to me this doesn't seem like a good thing. It should drop 5 degrees or so, one would think. That's been my experience with Intel quad-cores, anyway. Then again, I have better case air flow and improved ambient temps then I did prior.

thanks for your responses everyone!
i ordered a Cooler Master Hyper 212 EVO for myself and an Arctic Cooling Freezer A30 CPU Cooler for my friend that uses the same cpu but a different mobo (asus m5a99x evo). Mine cost 25 pounds and my friend's 30. Really curious who will achieve the best results. I am pretty sure at this point that the stock coolers are complete failures.
Seriously AMD either save us a few pounds and don't put such a crappy cooler at all or charge a bit more and put a decent one.

The hyper 212 isnt strong enough to handle temps with the fx 8350, i know from experience. I currently have the fx 8350 with hyper 212 and my idle temps are 40 and under load they are 55 to 60, with a .3ghz overclock which is a small OC. I just ordered the crosair h80 closed water cooler. hope it helps.

CrazymanWO :

Did you just use 1 fan on that hyper cooler ? if yes then that's why,
You need to have 2 fans blowing air the same way and then it keeps it cooler, Not having 2 fans both sucking this will do bad things and not move out the hot air from the cooler

I have used 2 fans.

I just orderded this if you need a suggestion for a closed water cooler.

hey guys!! I replaced my fan with a Cooler Master Hyper 212 EVO and I added one more 120mm fan for better flow. (pull/push). I have applied the thermal paste and reapplied the thermal paste and rerererereapplied the thermal paste. My idle temps are somewhere around 43 degrees but its pretty hot where I live. Now that I am writing this message outside is about 40 degrees. Under load I am somewhere around 57 58 at stock speeds. My motherboard also gets pretty hot (47 degrees) which I don't know if it is normal. Since I am in safe temps and I am not interested in overclocking at the moment, I will accept defeat. Who knows... in the future I might try water cooling.

I have just installed the AMD 8350 black, with Main Board ASUS Sabertooth 990 R2.0 32 gig ram, Samsung 500 gig SSD, XFX 7850 Ghost GPU over clocked by 115mhz stock. Running Windows 7 premier. Built it on Sunday and had it online by that night. Today is Monday. They say SSD's make your computer boot up in 15 seconds. It's true. Shutdown is smoking quick too. My fan on the 8350 is noisy also. However it is only about 21-22 celsius at idle 54.5 55 at 100%. I have it going at 100% right now. The fan is load but it seems to do its job. One spot in the case is 61, another 40. I do have a fan in the side of the case blowing in. I plan on replacing the side fan (it's at least 6 years old) and the CPU one. I don't think I need to replace the heatsink, just the fan.

Dude, 47 celcius is WAY cool. If it gets to the 70s and 80s then that's hot.

Anthony Su · Aug 19, 2013

If the fan seems too loud to you and you plugged the fan into the right socket, it may be that you've never heard a stock cooler before or you might've accidentally messed with the fan curve. BTW 47 degrees celsius is WAY cool, so it shouldn't be spinning up too much; try Prime95 to see whether that temp is maxing out the fan or the fan goes even further to jetplane mode. Also, the FX-8350 is a pretty hot CPU.

I have an M5A99FX, and a 8350 with a stock cooler in a Cool Master HAF XB.
With turbo core on with evrything else set to auto except the memory timings (XMP profile had to be put in manually to get 1866mhz to work) I idle just under 30 C at room temperature (~71F), the highest gaming temp I have ever had was 63C and that was in a 80F room. The MB temp never goes over 32C. If you look up the reviews for this case you will find that to be a consistant result-in fact several reviews on major websites use the same processor in the case. The stock cooler and paste are more than capable of controlling the heat in non-overclocked to about 4.5Ghz depending on the rest of the setup and ambient temperature.

If you idle at 47c then you probably will have an overheating problem at some point.

To actually offer you a solution instead of woulda shoulda coulda and speculation:
NEVER Run a computer in any kind of enclosed space.
ALWAYS start testing temps in a temperature controlled room WHEN YOU FIRST BUILD THE MACHINE.
and when you do have problems with heat, run it in a test bench (or even simply out of the case) to see if your CPU/MB are OK-older cases have terrible airflow and should not be used with modern hardware.

If it runs hot in a workbench turn off turbo core. set the ram to the SPD - NOT XMP - timings or just auto timings at 1333Mhz, and make sure you are using the most recent BIOS. Still hot, then it is likely defective hardware.

Idle in 80F ambient room temp is 33C on the CPU for me. Ambient temps over 80F will drastically reduce air cooled performance.

Anthony Su :

No, 62C is MAX for FX series AMD CPUs.

AMD CPUs run cooler than Intel which 47C is an iceberg of an Intel chip.

@OP: Honestly man, if ambient is 40C...then you're not likely going to see much better than what you're already getting without going to some sort of evaporative cooling setup, or an aggressive water cooler.

One tip I can think of is to place your PC where the cool air from your A/C unit is blowing somewhat directly at your PC case intake fans. If your A/C cool air is going in, that will dramatically help lower temps.

(Note, I am not advocating putting your case directly in front of an A/C vent, just get it to where the stream of cool air is blowing at the case to keep ambient temps lower)
