still my rear case fan, is pretty close to the noctua... so idk...
Very little.. maybe 0.5-1c.

Was about to ask how low I should put the middle fan, but you already answered it lol.

Yeah, you wouldn't see much of a difference. I say stick with the two fans included.

You wont get much lower temps by adding a third fan 1-2 degrees, but it will allow you to run the fans at lower rpm and achieve similar temps.

I have my NH-D14 oriented so that the air flow is vertical, exhausting out the top. I've measured that VRM temps are 5-8C better, while the CPU cores are 2-5C better, with much less delta between hottest and coolest core, in this orientation vs. a standard horizontal/exhaust out the rear, setup.

However, this is on LGA-2011 platform where the CPU cores are organized differently than most, and my ASUS P9X79 WS motherboard's primary VRM sink is along the top edge of the board, with no sinks near the rear I/O ports. Hot air from the GPU hasn't really been an issue, as my GPU is in the fourth slot down on my board.

interesting. i never thought of putting the GPU in a lower slot if available. i always thought it had to be in the top slot.

In some motherboards it might cause issues or performance loss.
Some motherboards that support crossfire/sli with 8x lanes active in both PCIe ports will only "use" the graphics card in the bottom slot if the top slot is being used(example being current Intel LGA1155 motherboards).
I always prefer having it on the top slot, cause it avoids all kind of problems that shouldnt happen to begin with.

I have my noctua pushing air from the back with no rear fan, it pulls fresh air from the outside which gets exhausted from the top/front.
It gives me a good overall temperature and a nice air flow.
Both my HD6850's max out at the same temperature, 68 degrees with stock cooler and overclocked with 1.2v from a stock of 1.15.
Using your typical fan configuration with a solo 6850 it would max at 72 degrees.

So far I'm pretty impressed with the cooling ability of this NH-D14 SE2011.

This is with 30-32C ambient temperature (as indicated by the actively cooled, idle, SSD), and 35C+ air entering the heat sink, 13 hours into a very long Prime95 AVX run, with Furmark in the background to increase case/room temp:



I figure the CPU is pulling about 230w at the moment, so a sub 50C temp rise is not bad at all.

Depends on board.

Most PCI-E slots will take a GPU, and if it's a 16x electrical slot, there should never be a performance reduction.

Your motherboard manual should have more information.

As you say, it varies from setup to setup.

This board (ASUS P9X79 WS) has two 16x electrical slots (blue, #1 and #4) that are 16x unless, both 16x and at least one 8x (black) slot are also loaded. All of the slots will take a GPU without issue.

Hey guys. I'm thinking of getting an NH-D14 soon, and I was wondering if anyone has any pics of it with Prolimatech Blue Vortex 140mm fans. I'd just like to see what it looks like.
I'll have a look around the thread, but I figured I'd ask anyway.

Oh and temp comparisons would be helpful if possible. Thanks in advance.

Just fix your brackets.

Because your chipset doesn't need to alternate the bandwidth fed to the other PCIe slots.
The 1155 platform when they have 2x PCIe, they are rated to work at 16x on top solo graphics card or 8x/8x dual graphics card.
The problems arise when the bottom graphics card isn't fed the PCIe 8x bandwidth cause the top PCIe slot is not populated... It's a problem with the motherboard...
It doesn't happen with my motherboard tho... I can use one of my four PCIe slot's for a graphics card and they will all work, which is cool. tongue.gif
X79 shouldn't have any problem with which PCIe lane you choose to run, it doesn't have to split the bandwidth.
