Noctua NH-D15 with GTX 1080 ti

deepai · Mar 25, 2017

I'm building a deep learning AI system that can make full use of the GTX 1080 ti power when training models. It'll be running continuously for extended periods of times (potentially for a few days) at high power. I've chosen the Noctua NH-D15 as a cooler and had two questions about it:

1) Will it be capable of maintaining good temperatures that allow the system to run continuously?

2) The website mentions that on the motherboard I selected, it'll block the first PCI slot and will have to shift the graphics card over. I read that this is the "prime" slot for best use of the gpu. Do you think it'll degrade how much power I'm getting out of it because of this change?

Also, is this an appropriate build for this purpose?

Thanks!

There is a guy who attached a coolermaster hyper 212 evo on his gpu. Just saying.

It would be quite something attaching an NH-D15 on a gpu.
Sorry I realized I wasn't clear in my explanation. I meant that I'm using the cooler for the cpu but the way it's going to be placed would overlap my first pci x16 slot so I won't be able to put the gpu there. I have another pci x16 slot (third one down) that I can use. However I read conflicting posts about whether the non-first pci x16 slot would provide the same performance as the first one. So to sum up, would placing my gpu in the third slot down (still x16) on an Aorus z270x Gaming 9 motherboard reduce the gpu's capabilities relative to placing it in the first slot?

Uh................. what?

deepai :

Well it'd be physically impossible as a) no mounting brackets exist, and b) even if they did exist you'd most likely wind up breaking your card due to the excess weight.

Yeah PCI slot placement isn't that big of a deal. The extra slots are there for 2 and 3 way SLI usage and they're the same speeds as the other PCI slots. So you can use the card in the lower most slot and be fine. It's really a matter of how you set your airflow up.

Sounds great, thank you!

Im not kidding, he literally twisty tied one n his gpu.

Did you check the ram? I think you will have problems because corsaire dominator are pretty tall and the dh-15 has a limited space for ram.

Dragos Manea :

Bro he will put it on his gpu.

Dragos Manea · Mar 29, 2017

No he will not, pay atention "I'm using the cooler for the cpu but the way it's going to be placed would overlap my first pci x16 slot so I won't be able to put the gpu there", a few posts above.

This is hilarious.

Sniff sniff, ill go to the corner

deepai · Mar 29, 2017

You're correct Dragos Manea, I won't be placing it on my gpu. It sounds like a disastrous idea.

Thanks for the heads up about the ram clearance. Turned out that it won't fit with the two fans in place even if I raise the second one. It'll have to be a single fan setup.

But the Noctua seems to be a headache for its size. Would you recommend an alternative that would do the job but not be as big? Keeping in mind that I'll be running the computer at full power continuously for a few days at a time to process my data. And that I might expand the number of gpus in the future.

Cooler master hyper evo 212

Dragos Manea · Mar 29, 2017

Well an alternative would be NH-U14S or a liquid solution (an aio) if you have space for a 240mm radiator.

deepai · Mar 29, 2017

Dragos Manea :

Sounds good, I'll look into those. Thanks for the help everyone, I appreciate it!

Guest · Mar 29, 2017

Cooler master hyper evo is good enough

deepai · Mar 29, 2017

Thanks Inonothingatall, I'll check it out as well

Dragos Manea · Mar 29, 2017

This cooler is not ok anymore, it is designed to transfer heat a bit more slowly, while the new cooler are more effective in transfering heat. An i7 700k will overheat with this cooler with prolonged 100% usage.

OP go for noctua or a 240mm liquid cooling.

Guest · Mar 29, 2017

? Ummm ok.... Ill just keep quiet.

deepai · Mar 29, 2017

Thanks Dragos Manea, I'm thinking about the Thermaltake water 3.0 240mm. My knowledge about coolers is very limited. Would you recommend it?

Dragos Manea · Mar 29, 2017

Yes it is one of the top 240mm cooler along with corsair h100i v2,nzxt kraken x52, deepcool captain 240. Do you have space for a 240mm radiator in your case? If so then yes thermaltake is a good choice.

deepai · Mar 29, 2017

Yep there's space at the top. Perfect, Thermaltake it is then. Thanks a lot! That was really helpful

maz89 · Mar 29, 2017

I would personally prefer an air cooler, something like the Cryorig R1 Universal or Phanteks PH-TC14PE.

Dragos Manea · Mar 29, 2017

maz89 :

They are really big and they obstruct ram slots.

EDIT: I m have almost the same cooler as you, nh-d15 because it is the only serious cooler for am4 and trust me i hardly wait for my corsair h100i v2 bracket for AM4 because it restricts me very much.
