Asrock FM2A85X-ITX - the ultimate FM2 ITX mobo to lust for? - Page 22

post #211 of 213
Right now I'm using the stock cooler and the case is Abee T20R (doesn't get much better than this as far as airflow in a mini itx case is concerned).

Idle temps are low-mid 30ies (fan on lowest speed) load temps currently somewhere in the low 50ies (fan at full blast).

At first I was using this 6800K on a Gigabyte f2a85xn-wifi with a Scythe Samurai ZZ (supposedly safe for up to 130W TDP). Right off the bat the temps seemed atrocious to me:
- on stock settings the BIOS readings were ~57°C,
- with CPB off ~46°C,
- turbo always on ~70°C (all open case)
I haven't even bothered stress testing this setup and tossed a 6700 in it instead. Thankfully this one behaved better, reporting ~40°C on stock settings.

I decided to keep the 6800K (DDR3 2133 support) for use with the asrock board and limit the core clock, hoping I'd be able to at least replicate 6700 thermal behaviour. Temporarily using the stock cooler the temp rose to cca mid 50ies if left idling in BIOS at 3.6GHz but I figured I'd be safe since BIOS doesn't engage any energy saving features and reports "close to load" temps (?).

Unfortunately during the first p95 run the computer shut itself down mere minutes into the test (I should note I never even got to see any p95 errors). Immediately I assumed the APU reached Tmax (only 74° on this?) and shut itself down to prevent damage. I "drastically" lowered the clock from 3.6 to 2.8 GHz to check if there were other factors responsible for the shutdown and sure enough 6+ error-less hours of p95 confirmed my suspicions.

I'm hoping I'll be able to run this at 3.2 GHz once I get an appropriate aftermarket cooler but so far it seems I'm a "random victim" of a poorly applied IHS, an inevitability since they switched from soldering the IHS to using thermal grease.

I would like to use this board in a UNRAID build along with my A4 5300 APU installed into a Fractal Node 304 case, my main reason for selecting the board is the 7 SATA ports, I cannot find any other FM2 motherboards with over 6 SATA ports and I intend to install 6 HDD and 1 SSD. Are there any issues with this board being used within this application, or suggestions for a different board?

I have this motherboard inside a Fractal Design Array R2.
Using this as my UNRAID-server and it works lika a charm.
Im so far not using all SATA connections but will soon need them all.
My only concern is the stock CPU cooler for the AMD A4 5300 makes too much noise.
Will have to look into aftermarket cooler that fits in this tight case, but Im sure it will be sorted out.
Good board, nice chassi

Best regards
Anders from Sweden
