Hey guys I’m in the process of putting together a Unraid/server build in a Corsair 678c.

I’m planning on using an Aquantia 10gb nic (ASUS Areion) but while it has a large passive heatsink it runs hot even when idle.

I’m looking for a way to dump as much of this heat as possible and wonder about the possibility of using a PCIe slot exhaust fan, provided of course it’s not too noisy.

Has anyone ever tried one of these? They come in both blower and 10mm fan flavours.

I have my eye on this one but wonder how noisy it is.



Thanks
 
OP, would you not be better with the likes of the

ASUS XG-C100C PCI-E Network Interface Card

Is it this one?

If so, I'd remove the top plate if possible, leaving just the heatsink (therefore exposing more fins), and then the Front to Back case airflow should be more than enough.

Those blower fans are normally noisy

Thanks for the replies all :)

Yep, that’s the one. There’s no way to remove the top layer and expose the fins unfortunately, its moulded metal and sealed together with the section along the top for the led indicators.

You could always use a fan controller of some sort if too noisy

Was thinking this. It’s just a standard molex connector so easy enough to switch the pins over to 7 or 5v.

PCIe slot fans are notoriously loud and move almost no air.

Have you considered just removing other PCIe back slot covers? Assuming your case as enough intake vents good fans in them, case should flow plenty of air from intakes back and out open PCIe slot openings.

As above the pcie slots are perforated, I’m not sure removing them will help much.

What I’m thinking of doing is buying a 4x pcie riser cable, running this to the vertical GPU area in the case (2 pcie slots) place the ASUS ROG Areion in the first slot and one of those PCIe exhaust fans directly next to it. Thinking that way the heat generated by the NIC will be immediately exhausted out the back of the case and won’t get a chance to affect overall temps (that’s the theory anyway!)

I’m using all 5 PCIe slots on the board. If I drop the NIC in next to the other cards the heat generated is insane. I need to either keep it separate or find a way to remove the heat quickly enough.
 
I assumed it was the same but was thinking it would be cooler without all that shrouding making it more bling than practical rather than buying it and remove shrouding like Mod above said.

Added to the one above is in stock and the other is not non places I looked.

Sounds crazy because it is just a NIC but the rest of my build is grey and black so that was the decider - lol my OCD.

While it is available separately (maybe only in stock in Aus) the ROG Areion comes bundled with the x399 Zenith Extreme mobo.

I’ll maybe try a PCIe fan like the one above and see how it goes. They’re not too expensive so if it’s a fail I’ll not have lost much - worth a try I guess!
 
You can always change the order of the fan cables, from 12V to 7V, if needed.
Main issue is if close to the GPU, which may give insane temps.
 
If you're only going to have a GPU (top spot) and the network below it, depending on how much space is left remaining, you could grab a normal more silent fan that's small enough to fit under the Network card, and exhaust directly outwards on the PCIe slats at the back of the case. Just make sure there's some cool air coming across down at the Network card level. I've used this method to help keep a GPU cooler.

The easiest solution. I'm using 2 of those generic PCI brackets for fans, as I'm running the push/pull at the minimum speed possible, but to avoid lack of airflow, 2 very quiet fans, one pointed diagonally towards the back, cooling the RAM, NWME and and the VRM. Bottom one, same orientation, cooling the X570 chip and the M.2.
Inaudible.
 
I found and ordered a x4 riser cable. The 678c has vertical GPU slots so I’ll try putting the NIC in there (should hopefully keep it far enough away from the other slots to not interfere with temps). Still thinking about the possibility of adding a fan too so one of those brackets combined with the riser cable may be the ideal solution.
