Description

Lazer3d LZ7

Ryzen 1700

GTX1070 AERO ITX OC

I wanted something very minimal, unique, small and well ventilated. I've choosen LZ7 but the main problem was the cpu cooler, under/equal 60mm are very noisy, have poor cooling performance and for AM4 there is almost nothing.

Then I remembered about the best CPU cooler under 70mm: Zalman CNPS8900. They sent me the wrong AM4 adapter kit but then I realized that also with the right one I would have problems with ram clearance, so I decided to use some parts of the wrong kit and make vertical oriented brackets by myself. LZ7 has lateral intake, so lateral oriented heatpipes shouldn't be an issue. I could say this is my first step in Modding!

Building LZ7 is so funny and fast, no problems, no side panels that block the hands while working! This case is a MASTERPIECE for sure!

Ryzen 1700 is the most efficient of the line, very low temperatures! 3.2Ghz with XFR, no manual overclock. 60°C After 4 hours of Prime95. 46.5 with Aida64 CPU only stress test.

I don't know why there is not Prolimatech Ultra Sleek Vortex 14 in pcpartpicker.com, it generates a huge amount of airflow for such a small depth, so nice and well built!

EDIT 11/11/2017

Someone in the comments shows that Zalman CNPS8900 Quiet fits also with original AM4 Kit with 1mm ram clearance!

Part Reviews

CPU

Impressive low temps for high performance!

CPU Cooler

Inaudible at full speed! Best cooler under 70mm. Helps in cooling all around (Motherboard, VRM, RAM and maybe the GPU), very important for components lifetime and overall system stability.

Thermal Compound

Ryzen 1700 at 60°C on Prime95 in a 7L mini pc case!

Motherboard

Nice layout, I've tried to overclock my Ryzen 1700 to 3.8 and RAM to 3333Mhz.

Memory

They work well with Ryzen, overclocked to 3333Mhz without problems.

Storage

No overheating in my build.

Video Card

Silent, only a little noise at full speed, 57°C on FurMark 4K stress test. No coil whine at over 230fps!

Case

Small, Stunning, impressive venting, with a lot of possible customization.

Mounting every single piece avoids obstacles when installing every single component, GPU install is very simple despite lenght space is very tight.

Panels have a matte finish, nice at touch. When assembling is completed the case is very rock solid.

The GPU ha 360° venting, very important with itx graphics cards that push hot air up,down, rear, front. I don't if is rilevant but GPU is cooled also on the back of pcb, expecially in my build with the help of my flower cpu cooler Zalman CNPS8900 Quiet. Intake fan is very close the CPU cooler, in my build I have heatpipes in front of the fan (I think this helps a lot in cooling performance, after stopping CPU full load it takes few seconds to return to almost ambient temperature).

I reccomend the option with Vandal Switch with its panel for the cleanest cable management possibile. If you need max cooling performance with lowest noise, it's better choose fan grills option; same temperatures as an open air bench!

Really Satisfacted!

Power Supply

Silent also on load! Nice short flat cables.

how does the Zalman cooler work well against the stock cooler?

  • 25 months ago

I really don't know, this is my first Ryzen build and the stock cooler is over 70mm height.

Pretty similar to my build. But i'm using a node 202. I have the same CPU, motherboard, cooler and RAM. Just letting you know the proper zalman AM4 kit with the cooler mounted the other way with the pipes facing the ram do work. The pipes clear the ram by about 1mm. I did have to mod the case a bit to get the cooler to fit but.

I'm getting similar temps running the 1700 on stock. Have you tried to overclock yet. My r7 1700 keeps crashing on prime 95 after about 20mins at 3.7ghz. I think i may have to up voltage a bit because temps are not crazy high.

Its a great cooler very quiet much better than cryorig c7.

Where did you get the proper AM4 Kit? Can you provide a photo with the Zalman Installed?

Oh, Australia only...I live in Italy. I've tried to OC: 3.6Ghz without changing anything, I've reached maximum 3.8Ghz with higher voltage but I don't remember how much, but something under 1.35V for sure . It was for testing only, I don't want to overclock in this build.

So, what's your maximum CPU temperature running Prime95 for 20 minutes (maximum heat) without OC? Thanks a lot!

  • 24 months ago

From what i remember it was around 70 degrees on stock. But I didn't run prime on stock for too long I really want to get 3.7 stable. A bit higher than you but the big 140mm fan you have is probably helping as well.

I have bumped my voltage up to 1.275 at 3.7 from 1.25 its been running OK for the last couple of days but I have not run prime on that voltage yet. I'll run prime on it today probably and give it a go.

I'd really want to know if vertical mounting of the Zalman can decrease cooling performance. In the manual they reccomend horizontal orientation but in towers pc. Usually they say that heat pipes must be parallel to cpu die, like my solution, but who knows...

Hey there! I'm looking to use this cooler and your album isn't working for me. Can you tell me what am4 itx mobo your were using? I'm also assuming you were using the corsair lpx?

I've tested overclocking until 3.8Ghz but I really don't need it. I want low temperatures with high performance.

Are you getting a lot of dust though without dust filters ? Planning on getting this case but not so sure with the open vent. :/

  • 23 months ago
  • 1 point

No Dust for now, I think because of low rpm fan, thanks to its big size (140mm). I clean the inside with a CompuCleaner, through the holes, every month.

Hi there! Love this little case, got one and I'm about to update the front panel. That Vandal 16mm switch is it like chrome/silver or golden colour? Thanks a lot!

Chrome/Silver.

Awesome build for sure - could you see there being a benefit to using a PicoPSU 160xt or HDPlex 160ATX/160ATX+80DC? Like more air flow from the missing sfx psu & cables? Those temps aren't bad to begin with but I'm just wondering about OC headroom... Also how close was this to the memory? it looks like you had plenty of room but youre saying the actual kit will only have 1mm of clearance but I'm using the gigabyte ab350 gaming wifi itx - its dimms are all the way to the right up against the side of the motherboard... I have Gskill TridentZ which is pretty tall do you think this will be an issue?

  • 17 months ago

HDPlex heat will increase inside temperatures, Corsair SF450 is cooler ad provides a fan for more fresh air inside the case.

Gskill TridenZ are too big for this setup.

If you want the best venting configuration for a LZ7 you should use the standard one and a CPU cooler that won't block, air like mine or a Scythe Big Shuriken. Motherboard temperatures will gain a lot like this.

You probably could've gotten the Noctua L9a-AM4. $40, silent, included AM4 bracket with no RAM clearance issues, and it's Noctua.

  • 10 months ago

Nope, flower like heatsink also helps motherboard cooling. CNPS8900 has already AM4 brackets, is REALLY silent and nice. Look at this test where the noctua is throttling. L9a/i is for very low height chassis.

I'm running into the exact problem you are having. Using AMD AM4 on ITX board. The standard AM4 bracket does not work as the ram is closer to the processor and the heatpipe gets in the way. What did you use to make your brackets?

  • 2 months ago

Steel.

Can you clarify exactly what you did? I'm looking to use the am4 kit but I'm not entirely sure how to mount it because there are no instructions.

I've created my brackets because I didn't have the AM4 kit.

This is the most silent gaming build I ever made! There is little noise only with all fans at 100% .

I'm impressed by the smaller 1070 coolers (Gigabyte ITX, MSI Aero, Zotac Mini) and the 180w TDP. Pair that with a 65w CPU (regular Intel and AMD) plus a trusted cooler (maybe an AIO) and a good airflow fan and things work well.

I cobbled together a system this weekend with the Zotac 1070 Mini in a Sugo SG05-bb lite using an 84w CPU, Cryorig C7, and Noctua Industrial 120-3000 fan for intake. The thing drives anything at 1080p without breaking 65C on the GPU and 60C on the CPU. Next gen stuff will be even lower tdp/wattage and I'm excited for that.

CPU at 60°C on 1080p gaming is pretty high.

  • 24 months ago

It's a Xeon E3-1245 V3 @84w cooled by a Cryorig C7 in a restrictive ITX case. Far Cry 4 is about teh most demanding thing I throw at it to push the CPU past 65C which is higher than some synthetic tests but I think this is due to the GPU heating up air inside the case and I need to figure out how to add an exhaust fan or find another CPU cooler for this configuration.

Except I'll probably rotate parts around before the end of the year so I don't think a little AIO is worth the money.
