HDD_1: Seagate ST1000DM003 1TB, 7200 rpm, 64 MB

HDD_3: Seagate 2 TB, 7200 rpm, 64 MB
PSU: Corsair HX520 W
Case: Fractal Design Define R4 Black Pearl
Now, I have problems with this AMD CPU....it's hot.
I think problem is in CPU cooler, H50 and VRM's on ASRock 990FX, Extreme 3.
This H50 is ok for CPU but it's not great solution for cooling VRM's of this poor 4+1 MBO.
What's your advice about cooling? Maybe to replace H50 with top down cooler like Scythe Kama Cross 3 or I need to take new MBO (it's not great solution right now)?
About air flow in Fractal Design Define R4, what's your advice's? Two 140 mm intake in fron of case, one 120 mm intake at bottom (because of cooling GPU) and for exhaust fans maybe to put two (or one 140 mm) fans on Fractal back side? Now I have one exhaust fan on Fractal top but will be better to remove that fan and put it on Fractal back?
Changing MBO is my last option but I will do that if nothing else help with temperatures.
Thank you all on advices!
This is short log from AMDOverdrive just to see temperatures:
We must make the hot Asrock club... If you are after 4Ghz, follow my advice here:
If you don't want to run 4Ghz, you can follow the same guide, except the part about raising multiplier and instead aim for 3.5Ghz@ 1.18v more or less. But you will lose turbo clocks. I can't offer an undervolting solution with turbo on, unfortunately.
The H50 isn't very good as coolelr. The Asrock 970 motherboards, no matter what you do, what cooler you use, will always run hot. The info you provided tells me nothing useful about how hot your motherboard runs under stress, but it's a typical Asrock trait.
As for motherboards in AM3+ and FX8xxx:
If you want to sleep without headaches, you 'd better aim for at least 6+2 phase from either ASUS or Gigabyte. With Gigabyte, you will have to struggle with BIOS bugs.
If you want MSI, you need at least MSI 970 Gaming.
If you want Asrock, you need at least 970a G3.1 and provided you are happy with something like 4Ghz and not after overclock records.
The Asrock boards will still run hotter to the competition, because they 're thinner.Edited by Undervolter - 6/14/16 at 7:42am
