Hi I upgraded my pc with new cooler, noctua nh -d14. I can't realy understand whether temp is too low or fine. I can't control the fan speed so I just run with LNA at 900 rpm. When Im just browsing, I run few aplications wich reports temperature (core temp, amd over drive, open hardware monitor) , and all applications shows temp dropping down to 13C and then going up to 25c, and then up and down, up and down... so I don't understand what is the real temp. my room temp is arround 20c and as Iv'e heard its not recommended to have cpu temp lower than a room temp. I noticed that bus speed of cpu is jumping from 1405 mhz to 4212 mhz also up and down... I think everything is auto in bios, should I change to manual and raise the voltage up in order to raise temp over the room temp?

The sensor or software is misreporting .... unless of course you are using your computer in an area well below room temperature (13C ~ 55F). Your CPU is not below room temp as it has no way to get below room temperature using an air cooler. To get below room temp you'd have to cool it with something cooler than room temp which the D-14 does not provide.
CPU speed varies with load, you want a constant speed, apply a constant load.
Download HWiNFO64 and Asus Real Bench and try again

I still have same results, is that normal that frequency is jumping so drastically? From 1400 mhz to 4200mhz (i mean, these are the only numbers i see, theres nothing in between). and continuously jumping up and down on idle. I understand when speed changes depending on load, but why it jumps half way up and down on idle? If those applications which i have are showing wrong temps, would you recommend any program for amd 8350? (Amd overdrive shows same stuff). I didn't find HWiNFO64 showing temp. Just makes me panic when i see program one second showing 13c next second 25c and after that i straight away check bios and i see 40c that means i was entire time provided with wrong temp information also getting same results with amd over drive... Its my first build and im total noob about this, so it makes me stress a lot... As I understand there's no point of making these stress tests if I am provided with wrong information... Also all settings in my bios is auto, and im afraid to change anything without proper knowledge. I have option to control fan speed in bios, changing duty cycle. some people said even if noctua fan has 3 pin connectors its still possible to change speed. But i can do what ever I want, speed stays the same... My bios is updated. It did work with amd stock cooler. However i would be more than happy if i could see constant temp (without ridiculous jumping) somewhere, somehow, (not in the bios) so i could feel calm about my rig. Would be even better if i could could control fan speed, and at last, i which to know if its normal for my mobo north bridge digi+ power control normal to get so hot, that i could cook egs on it.

Again, the speed is jumping because the speed acts in response to load .... when you are "idle", you are "mostly idle". Open task manager and you will see this is not actually the case.
In BIOS no windows based power saving features are active so CPU is always full speed. It will therefore be hotter than when at idle in windows.
CPU temp is reported in numerous ways..... usually a package temp which is an aggregate of numerous sensors as well as core temps.
HWiNFO64 reports many temps.... run it with sensors only and scroll down the list.
Again, the only temperature of significance are those when under fill load. It's kinda like worrying that you have the heat in your house set at 72F and its 69 outside and your heat hasn't turned on. The concern with regard to a heating system is can it keep the house at desired temperature when it is as cold as it gets in your area.
Put your CPU at full load (Asus Real Bench) and then see if your cooling system can handle it.

I feel so stupid. I don't understand whats the point of making these tests if temps reported are wrong? I just don't get, i know that on stress my cooler handle fine, but i don't get why on idle i see temp jumping 13c to 25-30c how i suppose to know which temp is right. That really confuses me. Could you also have a look at my previous post as i was editing when u answered. Maybe it will make more sense about what i mean. Sorry for frustrating you, but i just want to make sure i don't have faulty mobo or other components, also don't want to ruin them with my stupidity.

Not sure where you get "wrong" from ..... (well except for the 13c which is impossible) If I look at my phone it reports 5 different times from 5 different cities all over the world .... are 4 of them wrong ?
They are measuring different things.
1. Is it normal that cpu speed jumps ? - yes, except when it is under full load for which for some reason you seem reluctant to do.
2. Why does it jump on idle ? - because in truth it is NOT idle. Again, the CPU will be asked to do various things after startup .... mine doesn't calm down for a few minutes after booting it's usually at 4 GHz + for a time and then chills put to a relatively stable 800 Mhz ....to it still spikes. Under load it jumps to 4.7 GHz. I fail to see why this is considered significant. If you were watching your electric meter on your house, would I see jumps while everything is at idle ? What about when your fridge compressor went on, what about your AC ? All these things happen in the background w/o user input. Again, if you opened Task manager, this would be very evident.
3. If you connect your fans top the MoBo ....
a) Most non low budget MoBos come with a speed control utility (i.e. Asus FanXpert).
b) Failing that there is usually limited speed control in BIOS.c) can always d/l SpeedFan and see if there's a profile for your MoBo.

Have a look at the image below. both sofwares shows minimum 13C
This is after I left my pc on IDLE for a while. I didn't touch pc for an hour and a half so its not after start up. and my speed didn't settle down to 800mhz like yours, even if my bios is all auto... one sofware shows current temp 16C as you see.
but under asus sabertooth tab cpu curent temp is 34C , same temperature I see in asus ''al suite'' software. but as I understand this is mobo cpu socket isn't? That's how I see my temp all the time and its confusing, if 5 softwares shows the same, and you say that 13c is impossible. On idle, temp literally, in ten seconds, goes up and down twice, from 13C to 30C. People says thats because sowtware reports temp from different areas. So ok then, which one should I rely on and where that 13C comes from?

1. If running two utilities at the same time, that's one sure way to get erroneous readings
2. I still don't understand the fixation on idle temps. Like complaining about mileage for a car that's running in the driveway.
3. Is your room cooler than 13C ? If not than having a component on the PC that is 13C is certainly contrary to the laws of thermodynamics
4. It would appear that energy saving features are working as HWiNFO shows what I think is core multiplier ranging from 7 to 21. We haven't done a AMD based build in almost 4 years so I'm a bit rusty. But as I said previously, the sensor is prolly supplying a false reading.... not at all uncommon on AMD boards.

Sound familiar ?
5. Again , forget about 13C ... it's not real and idle temps are of no real significance.
Your CPU temp can not be below room temperature without an alternate source of cooling. You have an air cooler.... and you can't cool something that is 13C with a 20C "coolant". Any condition in which this was "real" would require entropy to reverse and the universe to collapse.
If you are going to load the CPU I will be happy to help you further, but I can't give you any different answers to your system's "imagined" 13C issue.
