New custom built PC possibly unstable

[Herrasmies]

Since first boot I've noticed many alarming things such as stock CPU cooler running at 100% speed near 4K rpm, high idle temperatures such as 40-50C, motherboards chipset heatsinks seem unusually hot and I feel like the warming up heatsink is causing extra work on the stock CPU.

Also hardware monitoring programs such as FanSpeed and HWMonitor report weird jumpy rpms (from 1K to 2K in an instant) for some fans and some there seem to be random max readings of 20K or 60K to which I have no clue whatsoever.

I've managed to make the temperature readings stay inside the factory recommendations even while gaming by adding an extra case fan and making chassis and gpu fans rotate on higher speeds full time.

I'm getting an after market CPU fan to replace the stock one, but I'm starting to doubt whether the stock is actually the one to blame.

Any suggestions what could/should I do? And whether this is normal or if there is something that I've overlooked in my setup.

The newly built rigs components are listed below:
CASE: BitFenix Prodigy M
MOBO: ASRock 970M Pro3 AM3+ mATX
GPU: MSI GTX 750 TI
PSU: XFX 550W Black Edition
CPU: AMD FX-8320 125W 3.5GHz Vishera
RAM: 2x4Gb G.Skill Ripjaw 1600MHz CL9

My thanks in advance.

First thing you have to do is go into the bios to look at true temp, voltage and fan speed readings.

You can`t trust software, especially hardware monitor.

Aye ye ye ,My goodness people keep buying 970 Boards because their cheap buy the board made for the FX chip 990fx 970 will never read correctly

Hey again,

@AddRam

When read from BIOS CPU temperature starts heating up from 38C all the way up around 50C unless CPU fan is running incredibly loud.
Motherboard temperature on the other hand stayed put at around 30C.
And regarding the spastic chassis fanspeed BIOS aswell reported a jumpy 1 to 2K rpm.

Mmh the case is mATX form factor sized.

As i pointed out you are using the wrong motherboard for that setup don't know what else you need he also linked you to some boards that are the right one

If you want to stick with Asrock get this one i have this board as well

ASRock 990FX Killer AM3+ ATX AMD Motherboard 990FX Killer - Micro Center

Here's how I set up my Prodigy i5 rig and it's a beast ! Hope the pictures help show how great a H80i fits, then a huge Bitfenix 200mm front fan.
