i always try to build redundancy into my cooling systems, since i've had several system failures over the years caused by fan failures. with my strategy of "all components passively cooled; multiple low-speed case fans," any single fan failure should not stop or damage my system (i hope). i guess i would not disagree with the assessment of "overkill." call it intentional overkill.nightmorph wrote:... Given that you don't have a discreet graphics card, nor any hard drives in the upper chamber, why on earth do you have all those fans in there? It strikes me as a bit of overkill. ...
i'm sure all my fans are well under 800 rpm now. still, i may take your advice and try using Q-fan to reduce noise even further, while keeping the same number of fans.Rebellious wrote: Why aren't you using the CPU fan header? I'm also cooling a 125 Watt CPU + GPU with Ninja passive using only 2 anemic Noctua fans. I would not have been able to do that without thermostatically controlled fans. The Asus BIOS q-fan thingy ramps up the fans only when needed, but under normal use they run ~800 rpm which makes for a near-silent machine.
using a 3-pin Nexus D12SL-12 fan, connected to the CPU_FAN header, with start voltage 5V, i tried:Rebellious wrote:CPU header works fine with 3-pin fans. Set BIOS q-fan to:
auto mode start voltage = 5 v or lower
auto mode start speed = 30 deg
auto mode full speed = whatever AMD says is the max core temp for your cpu
i did not actually remove the stock northbridge heat sink, but i did place an HR-05 IFX directly above the stock heat sink, to see where it would lie on the board. i'm quite certain that the heat pipes conflict with the capacitors that are tucked in under the fins of the stock heat sink (see the first photo on my original post above).mdahu wrote:You say that you cannot install a thermalright HR-05. Have you tried? Are you sure? How about a thermalright HR-05 SLI or xigmatek PTR-N881 HDT.
I've completely removed the front fan cage, filter, and metal 5.25 bay covers to allow for a larger air intake and decrease the whooshing noise.AlpineCarver wrote:gpu's a little warm there.speedkar9 wrote:Idle CPU: 34, MOBO: 41, GPU: 59, HD: 38. Load CPU: 52, MOBO: 42, GPU: 90, HD: 38 *C.
maybe time to install a 92mm in the lower front fan mount of the solo?
