Hey guys. For a while now I have the titular cooler. I got it for dirt cheap second hand with no fans. However I have an issue with it.
I have 760K stock, and it freaking reaches 65C after about 5 minutes of aida stress test. It had the same temps with the box cooler.
Now, I have reinstalled it a couple of times, the same. Changed the paste, the same. Put 120 + 140 mil fans on it - the same.
I have reached under it, touched the heatpipes on the base, where they are supposed to be 60+, they are cool. But every software I use shows me 65C...
Is it possible, to have a broken heatpipes or something? I have no idea... Don't really know how to check for things like this...
AMD CPUs can be difficult to read temperatures for
Also 65 degrees is a fine temperature anyways, easiest thing to do is just pop open your case and feel your heatsink with the back of your hand or something.
No, it's not. The Noctua should not keep 760K on the level of the box cooler. And it's cold. The cooler that is... Always cold... Could it be cooler issue, and what possibly?
If you're cooler is cold then it's doing it's job, your CPU can handle up to 100C, or at least mine could.
Why did I spend money on it, if it doesn't make it cooler than the box? Why did I bought 8+2 phase mobo if I can't overclock it...
I have a NH-U14S, keeps my CPU under 40 no matter what. 65 with the beefier cooler and a 100watt TDP chip should be equally cool. What does your case situation look like? Any restricted airflow? Do you have any obvious damage to the heatpipes?
Then there is the question: Is your CPU thermal sensor broken? How much does your CPU temp move from idle to full blast?
The case is Arc Midi R2 with 5 case fans - 4 Fractal and one Arctic. All running at 7V. Idle is around 30-35, browsing and YouTube is around 40-45, depending on tabs, etc, streaming - 55-60, stress -65 after 5 minutes.
No visible damage anywhere on the cooler. There is nice spread of the thermal paste. Every time I am dismounting it, there is a nice spread.
I really have no idea...
What is your ambient temperature.
Usually doesn't go over 30C...
My board is fm2a88xm-extreme4+. It's an FM2+ mobo. The mounting is the same since AM2, but still, the cooler doesn't say FM2+... Is it possible to be a compatibility issue?
Edit: it sais FM2+... So it's not compatibility problem...
It should be FM2+ compatible. If you have around 30 ambient temperature the temps don't seem bad but the load temps should be better than the stock cooler. Are you sure you got the same temps with the stock cooler i feel like if you left aida running longer the stock cooler would be hotter. But if its the same then something is wrong and if its mounted correctly the only thing i can think of is the fan speed try a more aggressive fan curve and try it without the low noise adapter if you are using it.
The box actually kept it 61, but then the ambient was around 10-15... It is not the fans. The base of the Noctua is cold. I'll try and reinstall it again in a couple of hours and bring back the results.
Another question: how big is the effect of the thermal paste? I mean should I get something like Arctic MX4/Silver or the Cooler Master stuff for thirth the price will do basically the same job with couple degrees difference?
FM2/FM2+ Socket CPUs sometimes have weird temperature sensors - or rather, I should say, sometimes a monitoring programs picks up the wrong one.
My older Biostar A85W registered no less than four different temperature read-outs for my A10-5800K, one of which was the CPU Socket Temperature reading, two were the CPU Core reading, and the fourth was a bogus reading that read between 60-90C.
What temperature monitoring programs are you using?
EDIT - Oh! Aida! I believe that mostly picks up the CPU socket temperatures. If you can, try giving AMD Overdrive a whirl, although be warned, it used Thermal Margins for read-outs, not your standard scale - so it tells you the difference of how far you are from your maximum heat.
I have tried Aida, CoreTemp or something, and a couple others, that I installed, compared to aida, upon seeing the same readings I uninstall them.
I will be home in about two hours, I'll reinstall the cooler, tighten all the mounting screws (again), make a couple of tests and be back in here with the results...
Go for the delid
What is Delid?
Don't listen to him.
Delid is where you take the heat spreader, the metal part on top of the actual CPU, off. This is usually fine for Intel parts but as far as I know most if not all AMD CPUs are soldered heat spreaders. So delidding and is going to tear the CPU die in half and destroy the CPU.
Don't do this.

Please tell us what your motherboard manufacturer is. When I used my FM2 processors, the read out on them were inaccurate and impossible (sometimes showing -10 or something around 140C).
If you have Gigabyte download the Gigabtye Easy Tune and read the temps there
If you have AsRock get the AsRock Tuning Utility
If you have Asus it Should be the AI Suite.
Also Core Temp is only for Intel CPU's they never catered to FM2 or FX chips.

Asrock FM2A88X-Extreme6+...
I have the utility installed, gives me the same readings as Aida. AMD have much better chip to heatspredder transfer than Intel do. This is why 4770K was a freaking oven no matter the cooler. I will not open my cpu.
Yeah wont be able to regardless, unless you can get the heat spreader to a constant 500C to molten the solder.
In the end, no point since there is no thermal paste between the heat spreader and chip.
