N7 Core i7-8700K Custom PC

Modded Phanteks P400S case with Mass Effect N7 scheme and better air flow.

Kraken X62 and additional 140mm Noctua fans keep the system cool at nominal 4.7GHhz. Also runs happily but slightly warmer at 5Ghz.

Fan Configuration. So I actually started this build back in November 2017 when the i7-8700K first became "available". Since then I have been tweaking the fan configuration until where it is shown in the pictures. The general intention is to intake cold air from the front and bottom, run it over the components and exhaust from the back and top. Originally I had both Noctua fans blowing up and out of the top of the case but the one closest to the front was blowing cold air out so seemed of little value. Therefore I moved this 140mm fan to the inside side of the X62 blowing directly out across the 1080Ti. I also took the second Phanteks 120mm case fan and mounted it to the underside of the red PSU shroud at the bottom. This is sucking cold air from the front (from the underside of the shroud) and blowing it directly up at the hot 1080Ti. The final Phanteks 120mm fan is simply exhausting from the back of the case.

Temps. The i7-8700K @ 4.7Ghz runs at around 58C while being torture tested in Prime 95 (max heat mode) on all cores for a length of time. This is roughly 5C cooler with the front panel mod than without it and similar to running with the front panel off altogether and just the Phanteks magnetic filters in place over the front 140mm Kraken intake fans. I spent quite a bit of time down volting the CPU as this made a huge difference to it's temperatures. The fans are barely audible in this mode. None of the software or games I run (Mass Effect Andromeda, Fallout 4, Fortnite) get anywhere close to maxing out the CPU so it seems a bit unnecessary to run at 5GHz. Nevertheless, at 5Gz, the CPU needs more voltage, the temps rise and the fans speed up to a level I can hear them. A prime 95 torture heat test results in around 69C, but admittedly only after 30 mins or so.

So the CPU is cool. This is not always true for the 1080Ti. This is often hits 100% loading in games with the settings at ultra and operating near the 140Hz GSync limit of the Acer XB270HU 2560x1440 monitor. The 1080Ti hits around 78C and can make the glass directly adjacent to the fans quite hot. This is why I've currently got both the Phanteks 120mm blowing cold air at it from the bottom and the 140mm Noctua fan blowing across it from the side. The result is that the glass temp are back to warm and the 1080Ti fan speeds are lower.

Great case mod! Would love to see more pics of the interior... But definitely a plus 1!!

Thanks for the comments. I've had a chance to add a reasonable picture of the interior and how the fans are set up. I could post more if you are interested in anything in particular...

Nice Build man! What are your temps and fan setup ?

Thanks for the comments! I've added a couple of pics of the insides and how the fans are set up. I also added a bunch of detail on the temps to the description. I hope it makes sense!

What did you use to cut the plastic? Also, where did you get the rubber piece that goes around the cut?

I have the same case and am having problems with high temps after installing 1080 GPU

Hi! I used a Dremel 4000 for all of the cutting. The front panel is metal so be sure to wear eye protection as there are a lot of tiny metal fragments flying around. There are some good youtube videos on how to do this and also how to cut rounded corners using the dremel at 45 degrees. For the edging I used McMasterCarr: 8507K63 "Rubber Edge Trim 1/16" Inside Width, 5/16" Inside Height, 10 ft. Length". (https://www.mcmaster.com/#8507k63/=1dux3b0) Hope this helps!

Hey! Not sure if you still check this or not, but if there was any way you could link to the mesh/filter thing you used for the front or something similar, not sure what to search for to find it. Building a whole new PC soon and love the case but have seen people mention a little about the air problems so I wanted to fix it as soon as I get my hands on it. Thanks!

Hi CookieCubed, I tried various meshes but ended up using a dremel to cut out a rectangle from this: https://www.amazon.com/Honey-Can-Do-OFC-06208-Black-Vertical-Sorter/dp/B013TSW2P0

Although I got mine from Walmart for less. https://www.walmart.com/ip/Honey-Can-Do-Steel-Mesh-Vertical-File-Sorter-Multicolor/50276710?athcpid=50276710&athpgid=athenaItemPage&athcgid=null&athznid=PWVUB&athieid=v0&athstid=CS020&athguid=73eaf190-1f0-166dfba2507df0&athena=true

Behind the mesh I use a breathable black foam which came from an old graphics card packaging. This gives it quite a smooth finished look a bit like a speaker. Its easy to remove which I do every few months to brush the dust off. I'll add a couple of pics...

See if the last few pics (just added) make things clearer...

Hi there, just a quick question regarding your build: I already have the exact same GPU and am interested in getting this case, but PCPP is telling me that since this GPU is over the 290mm recommended size for the case some of the drive bays may be unusable. Was this an issue with you? I'm just new to PC building so I can't quite tell myself. Thanks!

Just seeing your message now and I'm sure your're well past this decision, but in case anyone else has the same question: there is plenty of space for a full length graphics card. If you want to add SSD's where they are visible on the back-plane adjacent to the motherboard, the 2nd from bottom <may> interfere, but there are 3 others places which won't in addition to the drive slots out of sight under the PSU cover. I'd recommend an NVMe drive directly on the motherboard for the speed, lower latency and convenience though.

Thanks! I really like this case too. I just wish there was a bit less restriction on the airflow at the front- but this does give us a very good excuse to play at modding! :-)
