Overheating during Prime95? (stock settings+hsf)

post #1 of 8
Thread Starter 
Just got an FX-8350 smile.gif .

New parts:
AMD FX-8350
ASUS Sabertooth 990FX rev.2 (updated to latest bios)
Sapphire HD 7950 Vapor-X
2x8GB Kingston DDR3-1600Mhz w/ECC
Noctua NF-D14 (is on the way, using stock HSF w/AS5 right now)

Reused parts, ~6yrs old:
Enermax Galaxy 1000Watt
Lian-Li PC-A71A

OS = Windows 7 x64, BD patches applied.

I was wondering if someone would take a look at a HWMonitor screenshot I took.



The Max values were achieved through a 20 minute Prime95 run.
Ambient temp was ~24-25c (if my multimeter thermometer is accurate).
The side of my case was off (it runs ~2-3c cooler when off, and I'm worried about my temps atm).
Stock settings/no overclocking.

I'm a little worried about the 65c on the CPU... or should I be looking at the package temp? The Asus software uses the higher number and throws me a warning when 65 is hit.

Is everything normal or did I get a crappy chip?

To be honest, invest in an aftermarket cooler, the one I have is a beast. Overclocked my system this week from 3.1GHz to 3.9GHz, if all is stable ill be going 4GHz and beyond. Max temp under prime was 52C for a 30 minute test. Stock HSF are a waste of metals and plastics. With my stock HSF my idle temps were 49C and load (not full load) where 65C+ at stock settings.

So either get yourself a very good aftermarket air cooler or water cooler kit.

The package temps are just the cores, not the cpu.

You should look at your "package temp", which is doing alright.

I think the "CPU temp" you are seeing is the CPU socket temperature, which is usually much higher than the actual CPU temp.

If my CPU core runs at 50C my socket temp can exceed 60C, but if I put a fan on the back of my motherboard the socket temp can almost match my CPU core temp.

When in doubt, always look at the temperature under your CPU model number.

Another way to find out: if you are idling and one of your temps dips below ambient, then that is the CPU core temp that you need to worry about.


Or you could just get AMD overdrive and look at your CPU temp from there thumb.gif

In my post I mentioned that I had a Noctua NF-D14 coming and that I was temporarily using the stock HSF.wink.gif

I had originally ordered a Zalman CNPS 9900 Max, but the mounting system was crap. The bracket actually had to be modified (bent) in order to install the HSF. It was impossible to get a good mount on the thing, and this is the first time I've had the money to build myself a system in 7 years, so I decided that I simply wasn't going to deal with it and sent it back.

I did the same with a Gigabyte UD5. I was used to their higher end boards supporting ECC and hadn't realized there was a new revision with UEFI and that they had removed ECC memory support from them. I sent it back and got the Sabertooth, which supports ecc... though aside from "enabled/disabled" there aren't any extra settings for some reason. The Gigabytes I had worked with in the past (my brothers UD3, and an AM2+ one before that) had several ECC options available...

So--keeping with that theme--I'm asking just how normal my results are. Keeping in mind my case is quite big (full tower Lian-Li) and that I did use AS5 on the stock HSF, if this is clearly a poor sample and temperature is exceeding the specs, I'm willing to go through the hassle of getting it exchanged.

EDIT: Forgot while replying that you posted your stock temps. If we are both going by socket temperature there isn't much a difference between ours (barring other variables).

Thanks.

Already had it installed. Overdrive shows each individual core and they seem to match up with the package temp.

So, it wasn't actually overheating... just getting up there? So, is 55c normal for stock settings/stock HSF (w/AS5)/full tower case w/o side panel?

Note: I'm probably going to replace my case fans in a week or two so I get the case ambient lower and put the side panel on. My cpu probably would have hit 60c with the panel on.

Yeah that's normal. Your CPU can handle 62C no problem, just make sure you switch to your D14 if you want to have a decent overclock.

It's already been said, but the Package temp is the one that you want to use with AMD processors. Keep it in the 60s and you'll be fine. Being in the 40s running Prime95 (which is a terrible program to test Piledriver with, BTW) on the stock cooler is actually a good thing. I'd bet right now that you make it to 4.8 with no problem on that 8350.

Thanks.

Its actually 54c under Prime95. Playing Skyrim (late to the party, previous PC couldn't play it) the temp is usually 49-51 (socket temp, haven't checked package temp while playing). Glad to hear that it seems ok and I won't have to exchange my chip though.

Not sure how well I'll do. I tried a little overclocking with the 9900 Max before I sent it back, but failed miserably (didn't try that hard either tongue.gif ). One jump of the multiplier would cause it to overheat. Keeping in mind that thing was not installed well and probably had too much paste and air bubbles. It was a nightmare to install. Also, I definitely want to re-enable cool & quiet after I find a stable overclock, if that is possible.

As mentioned before, I'm hoping to increase the airflow in my case as well. I'll be comparing the Noctuas to my stock case fans, and if they blow them away (pun intended), I might stock my case with them as well (pretty pricey, so maybe partially to begin with). My intake looks fairly restricted by my hdd's/hdd cage and door, so I've also been thinking about a Lian Li BZ-502 for my three unused drive bays.
