fx-8350 temp high

[nohuevos]

I've had my computer for a few months now and I've begun trying to achieve a decent overclock on my fx-8350 but the only problem is my temperatures are way too high. A few moments ago I was stress testing with intel burn (I've also used prime95) and my CPU reached 70 degrees before I stopped the test.

 

My cooler is the h100i with Noctua NF-f12 fans pulling air in from outside of the case.

My Fx-8350 is clocked at 4.7ghz on 1.45v

The h100i's pump is running at 2250 RPM

The idle temperature is 34 degrees. 

My homes thermostat is set to 20 degrees Celsius but I'd imagine my room is a bit warmer.

 

I've been reading around and I don't think my temperatures should be getting as high as they are especially with my cooler. Any ideas on whats going on?

 

* I will note that when I was installing the CPU cooler to the CPU, I tightened the bracket on both sides to the point of which they slightly bent. Could this be the issue?

 

 

Also a quick question. In CPUID it shows that my CPU temperature is 34 but it also shows the temperatures for each individual core being much lower at 15 degrees. Should I be using individual core numbers instead of the main one?

 

 

 

Like always, thank you for any help and my apologizes if this should be in the cooling section.

Im by far no expert, perhaps its because you are pushing 1.46 volts through? Not in terms of damaging the chip, but just too much heat. 

[helping]

is 1.46v your volts under load?

LLC or not and LLC aggression might mess that up.

 

70c is a bit too toasty for not stress testing and 50c is too cool to be believable. 

If HWM reading is based off of what your motherboard is reporting, that might be socket temp not chip temp, which typically trends 10~15c above chip max temp.

You are pushing 1.46V through your chip. I would push that down to 1.4V.

[Morpheus]

max I feel comfortable pushing through is 1.4v and that's usually for short amounts of time. honestly, I don't feel like you need to go higher than 1.4 for normal use anyway

[nohuevos]

Alright, I'll lower the voltage down to 1.4v and see what happens although from the articles I have read 1.45v isn't unheard of. Thanks for the quick replies

PD really isn't like some of the newer pansy i5's

 

you can shove a high amount of voltage through them, even 1.6v is fine as long as you keep temps in check.

I may be wrong but even if you're keeping the temperature down, shoving too much voltage through damages (long term) the cpu. Is that incorrect?

For the most part yes. Enough to care about? Likely no. PD chips can handle that voltage just fine. 

 

Something is up with OPs temps, either that h100 is really underperforming, the mounting is off, or the CPU reported temp is actually socket temp, in which case he's around low 60's to mid 50's which is acceptable. 

[TechFan@ic]

Maximum "recommended" voltage by AMD for the FX 8350 is 1.55v, so 1.45v is completely fine.
In fact I'm currently running 1.425v for 4.6Ghz & my chip stays will below 60c under gaming loads.
Download & use CoreTemp, I personally find it has fairly accurate temperature readings when the CPU is under load. Idle temperatures aren't accurate though.

I lowered my voltage to 1.38 and my pc crashed. Bumped it up to 1.4 and it crashed again so right now I'm at 1.4v @ 4.5ghz... should I buy some thermal paste and remount the block or does anyone think something else is wrong?

Thanks for confirming that the voltage was safe. I thought that it was fine but I lowered it for now. The Asus Ai Suite II software also reported 70 degrees while running the stress test so I'm inclined to believe it's the correct temperature.

Like I said, download CoreTemp, monitor the temperatures again. 1.45v for 4.7Ghz is fairly standard.

Your H100i shouldn't have any issue managing 4.7Ghz.

Keep in mind that prime95 stresses your CPU to extraordinarily unrealistic levels. As long as your CPU does not exceed 61c on the core during any type of real-world usage (gaming, rendering, decompression etc...) you're going to be fine.

HWMonitor is actually reporting 50c as a max temperature on the core, which is completely fine.

The reported 70c is the socket temperature.

Go ahead and pick up some decent paste and remount. 70c sounds a bit warm for a h100. You can try lowering your voltage a little, but your voltage under load is more important to look at. LLC features might as well be bringing to volts up to like 1.5v on load or something.

Look up online if that is in fact CPU voltage, because of the way AMD's sensors are, the temperature is technically only an estimation. That still might be socket temp, since my MB does the same. 

 

50c would only sound appropriate if you weren't stress testing and it had a large load to and hit that for a few seconds.

"CPU" temperature is the socket temperature which you should ignore.
The "Package" temperature is the temp of the hottest running core. keep it under 62-60c.

I downloaded CoreTemp and ran the intel burntest; it showed the same temperatures as the core's temperatures in CPUID  which were 51 degrees. It also showed an idle temperature of around 14-20 degrees, So should I go off of these numbers and assume my temperatures are fine?

I'd be inclined to believe that the "CPU" temp you are getting is the socket temp, which can go up to 71 before it's an issue (though obviously less is better). The CPU temp would be the ones that stop around 50. However, that seems to be a large gap between the Socket and CPU temps. Mine are only usually 5-8 degrees or so max, and often less than that. You might want to get some good thermal paste, and redo the mounting of the cooler and see if that helps lower temps/bring the two closer together. 

 

That being said, I would probably just keep an eye on it for a while, regardless of if you repaste or not, but as long as the "CPU" temp stays below 70 or so, and the Temps under the processor icon stay below 61 or so, I wouldn't worry about it. 

 

As a side note, if you have an 8350, why does it say 8130p? What even is that?

Yeah I'm going to order some paste and i'll see what happens to the temperatures.

 

As for the cpu showing up as a 8130p I have no idea. In every other program it shows up as a fx-8350

 

 

 

*alright just picked up some isopropyl alcohol and some thermal compound. Lets see what happens.

Your temps are great.

[Priller]

My take.

 

Use the Asus mobo utility as that will give you the most accurate temps. Coretemp, Hwmonitor, etc I have seen off by 10C.

 

For the H-100. Remove the power to the pump from the CPU header and connect it directly to a molex fan adapter. That should get the pump full voltage.

 

If your CPU is showing up as an 8130p then the version of CPU-z is outdated. Probably from a driver disk. Find a newer version of the Asus branded version and use that. It should report correctly.

 

If you find that the socket temp is getting too high then you can secure a small 50-60mm chipset fan to the back of the cpu socket and that will lower temps dramatically.
