CPU making a lot of noise

Hello there, so I installed a new CPU and GPU today.
Everything seems to work just fine. The CPU seems to make a lot of noise though.
I checked which fan was making the noise and its the CPU fan.
So I did some checks, installed HWMonitor and AMD Overdrive.
HWmonitor shows temperatures of around 55 celcius, with a min of 54 and a max of 84.
AMD Overdrive shows temperatures of about the same, more into 60 average.
This is all while not doing anything but just having a chrome browser open.
While gaming however AMD Overdrive show me temperatures of 30-40 celcius. :S
About the fan, AMD Overdrive shows me its running at 4500 RPM, but ive seen it stay at 5500 aswell while gaming.
Keep in mind, this was the first time I replaced something inside my PC and im pretty sure I installed everythign correctly so I dont think thats the reason.

motherboard: MSI FM2-A55M-P33
CPU: AMD Athlon X4 760k
GPU: MSI R7 260X 2gb DDR5
PSU: 500W Cooler Master OCZ ModX streamPro
RAM: 2x4gb cant remember which ones

Are these temperatures normal? and what about the RPM of the fan?
Any advice on what to do? New CPU Cooler? if so, which one would you reccommend?

Smart Fan Target is most likely the setting you'd need to enable to allow for thermal control of the CPU fan. It is probably expressed as a duty cycle or percentage and a temperature. A typical setting I'd use would be 6 (or 60) and 50C. This will keep the fan at a 60% duty cycle unless it reaches 50C, in which case it will speed up to cool the CPU. This alone may help, although you may still want a better or quieter fan, especially if you consider overclocking.
Make sure the CPU cooler is properly mounted, with the right amount of thermal interface material. If it is the stock one, the pre-applied amount should be fine.
I assume the PSU is a ModXStream Pro and the case is CM (not that it matters; this sounds like a CPU fan issue).
AMD stock fans tend to be noisy, you might want to check out an alternative. Any 120mm (or even 92mm) tower cooler will be better and quieter than the stock cooler. Rosewill, NZXT, Enermax, and Masscool have versions that are as effective but much cheaper than their CoolerMaster equivalents.

I'm pretty sure its properly mounted with the right amount of thermal paste. it is indeed the stock fan with a thin layer of pre-applied thermal paste on it. I'm not sure if I did something wrong on that part, as far as I can tell its properly installed. So I checked the temperature in MSI BIOS aswell, and there it shows a average of about 56-58 celcius and the fan at 5200-5400 RPM. I guess ill be buying a new CPU cooler, any suggestions on which one to buy? I have no idea what to look for, like sockets and different sizes? Dont wanna spend a fortune either, already went over my budget buying the CPU and GPU.

Ye so I checked the BIOS settings, but I dont really know where to look for this setting your talking about. The only settings about fans I found were about some CPU Smart Fan target which is set to <disabled>. And another setting for FAN01 which is set to <auto> and thats not the fan on the CPU thats making the noise.

When replacing my CPU I basically checked where the CPU fan was connected and thats exactly where I connected the new CPU fan. I guess ill be looking for a new CPU cooler, 30$ is not that bad.
 


Does the CPU Smart Fan target have any values? Usually you'll see percentages or RPMs. I would try setting it to something to see if that has an effect. Sometimes NO value (like "disabled") could make it go wide-open. If it has an AUTO value, set it to that.

Edit: If you do choose a value, let's say 25% or 800rpm, and the fan slows down, MAKE sure you go back and set it to more reasonable values. If the fan can't be controlled, then you likely need a new fan that supports PWM.

Ye, I enabled that Smart Fan Target now, 2 more options came up, one where you can choose temperature between 40 and 70C with 5C intervals, and another option for fan speed %. I put the settings at 40C and 62,5%. Looking at HWMonitor now, the RPM went down to around 4000, but going back to 4500 again, and still making relatively the same amount of noise, just a bit less. Ill check if putting the temperature setting to around 50-55C will make a difference, if it dont then I guess I have to buy a new CPU cooler. Thanks for the info guys, muchas gracias :)
