Hi everybody, i'm new here and got a weird problem. I upgraded my previous cooler master 212x cpu cooler to NH-D15 cause i read it's very good etc. I've seen people running around 4.8GHz, even 5GHz with that cooler, but seems i'm not able to get nowhere near that.

Max i got was 4,4GHz at 1.33v to keep temps down, if i increase clocks little bit more it goes 60C with prime95!

Things i tried so far: reseat cooler, reapply thermal paste, take off side panel, run fans at max speed (that made very slight difference)

Unfortunately, with the FX CPUs, things like Prime95 will always overheat them. Prime95 isn't an accurate real-world load scenario. I don't even think it is a good stability test anymore actually.

I prefer OCCT. Also, it is ok for the temperature to go over 60°C when you are stability testing. You just don't want it to go over ~60°C on a regular basis when you are using the computer normally. So keep an eye on temps when you are playing games and things like that, and make sure it stays under ~60°C. But during stability testing, the temperature on these will always be way high, it is just their nature.

It is a decent temperature for any CPU under a full load (even frackin' cellphones run hotter). Everything else is a pure speculation.
If you are just aiming for a record OC to pass Prime95, you'll be OK if you stay under throttling temps(no official number but it should be no less than 80°C). Someone on Overclock.net got a max temp. rating for your CPU from AMD support: 90°C.

If you are looking for stable OC that will run 24/7 - stay below 70°C at full load (run at least 30min stress test).

BTW, almost all Intel CPUs throttle at 90°C, so my assumption above is still on the safe side.

On amd site it said 62°C is max safe and after that fx-8350 starts to throttle, i don't know how true it is and really that's not the point. What brothers me is that noctua dosn't perform anything like what i've seen from reviews/other peoples, and my previous 212x was already doing what NH-D15 do!

Could not find this on AMD website, nor any other temperature-related info. But here's the thing: AMD FX-8350 is a 125W CPU. I've never had an AMD CPU since Phenom 9500, but I do have a stock FX box cooler layin around and I can tell for sure that this thing with two heatpipes won't hold fully loaded 125W CPU below 62°C.

Regrading your Noctua:
Considering the TDP of your cooling I still think that your temps are good even for your HP air cooling. Here's a bargraph from NH-D15 review:

Test bench had an 84W Core i7 4770K at stock clocks(3.5GHz / 3.9GHz turbo) and it shows 66.3°C in Prime95.

My old NH-D14 performed similarly in my uATX rig with a 130W Core i7-920 clocked at 4.0GHz, but I had an Antec P180 mini with a backside fan and a HUGE top fan, which contributed a lot to overall cooling performance, but I was still in a 70°C ballpark at full load during synthetic tests.

The reason why your CM 212x performs just as well, is because it is a bad-ass cooler too. I have similarly structured Thermalright Ultra-120 which replaced my Noctua and it does very well. The only disadvantage is noise level.

How well cooler performs is dependent on air temperature going into cooler. A cheap digital indoor / outdoor thermometer with wired sensor works great to monitor cooler intake temp. Take a 12" piece of stiff insulated wire and twist it into lead from sensor back and attach a clothespin to it. Clip clothespin to somthing solid and bend wire to place sensor in front of cooler intake. Put case cover back and monitor the cooler intake air temp. :D

We cannot compare maximum temps of 8350 and 4770k. They are completely different. Most AMD CPUs design to run at much lower temperatures limits than Intel. Some coolers work better on AMD than on Intel or better on Intel than AMD. Some claim it's because of the heatpipe layout in base, but I think it's at least as much about the boiling point of the liquid in their heatpipes. I think some of them boil at a little lower temp.

Most cooler testing in reviews is extremely inaccurate. They use room ambient for baseline temperature, not cooler intake air temperature. Cooler intake is usually 5-15c warmer and changes with fan speed and cooler changes.
There are reviews with charts showing TRUE Spirit 140 Rev. A cooling as well as NH-D15.

Ok. So, the thing is AMD FX Series have weird ways to measure temperature. DON'T trust anything except AMD Overdrive.

Use only this. Trust me. And cool your VRM's and chipset with something - if you go over 4,7Ghz you get tons of temperature and wattage. Keep in mind :) I'm kind'a busy right now, try Overdrive, if u have some questions - ask. I will answer when I get free :)

Yea, VRM cooling can help quite a bit with these chips. You do need to be a bit lucky with your chip and have a good lot of airflow in the case.

What mobo are you using?

Above 60c you can start hitting stability problems. Trust me I know. Shoot for low to mid 50's and your golden the lower the better. Right now my main rig runs below 40 under full load (which it runs 24/7/365) with a H100i and is very happy doing it. Soon when the temps drop for good it will stay high 20's to low 30's @ 4.4. I have always heard prime95 overheats the cpu even with good coolers which is why i have never used it.

have you ever touch the cooler, just to make sure its really hot or not
and what about your airflow?
about OC different chip would give different result, some may pretty fine with higher Hz some need voltage adjustment, some just stuck at certain point

I run 5ghz on my 9370 at about the same temps, but have a h100i in push/pull for the fans. You should be at similar wattage for similar clocks, it takes a bit to cool them I should be around a 250-300w load when maxing the chip out. That's a lot of heat to dissipate.
