My previous build was very roomy. With this new build, everything fits amazingly close with no room to spare.

Image

The bottom 120mm fan is controlled by the video card's PWM fan header, thanks to a small adapter cable.

I tried a few different fans before choosing the Noiseblocker PLPS. Other fans I tried (Scythe SA1225FDB12H-P, Arctic Cooling F12) had some PWM clicking when controlled by my video card. Finally it pays to have a box full of spare fans.

MSI Afterburner is used for setting a custom video card fan speed curve.

The 120mm hole was was cut with a nibbler hand tool. I used a template from http://www.mnpctech.com/ printed on self-adhesive paper. The case was covered in blue painter's tape during all work to prevent scratches. Both sides of the hole were masked to prevent work-marks from the nibbler. After cutting the hole, I sanded the edge with sandpaper wrapped around a hole-saw drill attachment. I used double-sided carpet tape to hold the sandpaper to the attachment. 80 grit followed by 400 grit.

The solid state drive is mounted above the optical drive.

I added Enzotech MOS-C1 Heatsinks to mosfets on the motherboard with Arctic Alumina Thermal Adhesive.

The slim PWM CPU fan came with a Scythe Big Shuriken. Scythe does not sell this fan without a heatsink. It blows toward the power supply.

The 140mm front intake duct has rubber trim along the edge to block an air gap between it and the side case panels. The other side of the duct had a huge air path short-circuit behind the front USB ports. I have covered this area with duct tape. Finally, I have removed the dust filter included with the case.

The Accelero S1 video card cooler was mounted without the included clear plastic spacers, as they seemed a little tall. I had to remove the long plastic strips from both sides of the radiator in order to fit this in the case. I removed the plastic cover from the heatsink base since it blocks some airflow. There is about 25mm space between the Accelero S1 and the bottom fan. There is only a few millimeters of space between the Accelero S1 and the front of the case.

I measured AC power consumption with a Kill A Watt.

Power Consumption without video card:

IDLE: 26W
CPU LOAD: 111W

Power Consumption with video card:

IDLE: 47W
CPU LOAD: 137W
CPU+GPU LOAD: 263W

Temperatures (25C Ambient):

IDLE: CPU: 40,35,35,40 - GPU: 37,37,32.5,32.5 (GPU Temp, Temp1, Temp2, Temp3)
CPU LOAD: CPU: 70,70,70,70 - GPU: 40,40,35,35
CPU+GPU LOAD: CPU: 73,73,73,73 - GPU: 70,70,71,69

Fan Speeds Idle:
Front: 700 RPM
CPU: 1000 RPM
Bottom: 650 RPM

Fan Speeds CPU+GPU Load:
Front: 1575 RPM
CPU: 1850 RPM
Bottom: 1300 RPM

CPU Load is one hour of Prime95. Torture Test In-place large FFTs.
GPU Load is one hour of FurMark 1.9.0. Fullscreen 1920x1200, anti-aliasing off, dynamic background, burn-in, Xtreme burn-in.

Fan speed, temperature and power consumption is significantly lower during actual gaming. The computer consumes about 135W most of the time while playing Left 4 Dead 2.

Suck Hole Cooling? :lol:

How resilient are the Philmore 0.88" part # 10-647 with Surface Guard Vinyl Bumpers # 9965? Where did you get them?

Nice build.

Any chance of a pic with PSU inside, just want to see how crowded it ends up and how you did the cable management. Btw where did you place the SSD?

I found the plastic case feet at Fry's Electronics.

The vinyl bumpers are from Home Depot. They are thin and a bit soft. They happen to fit the case feet perfectly. These prevent the case from sliding on my glass desk.

I have added a picture of the case with the power supply installed. The SSD is installed above the optical drive.

That is the nicest Q11 build I've seen to date :D

I don't suppose you happen to have a straight-on picture without the power supply, do you?

Like a lot of socket 1155 mini-itx motherboards, the ASRock H67M-ITX looks like the CPU socket is right next to the PCIe slot. How is it that the wide AXP-140 doesn't interfere with the PCIe socket?

Anyway, nice, clean build!

Edit: I did some searching, and found a similar build with lots of pictures. I'm assuming you did the same---the "heatpipe side" of the AXP-140 is what comes close to your video card, right?

That is correct - the AXP-140 heatpipes are on the same side as the video card. Very close but nowhere near close enough for anything to touch, even with possible video card flexing.

I'm building something very similar... two more questions:

Fan - Front Intake: Noiseblocker BlackSilentPro PK-3 140mm


How would you rate this fan in terms of noise? NB's own specs say 27 dBA, 1700 RPM, 90 CFM. How would you compare it to the stock fan? Did you try any other 140mm fans?

My PC-Q11B's 140mm fan is a "LI121425BE-4-A". I couldn't find any definitive specs on it. But on Lian Li's website, the "BS-05" looks the same, and has the same current rating (0.14 Amps). If they are the same, then they rate it at 22 dBA, 1180 RPM, 60 CFM.

The Scythe KAMA FLEX series also looks promising, particularly the SA1325FDB12M, rated at 1200 RPM, 23 dBA, and 75 CFM.

Good catch. I saw that air path short-circuit but it never occurred to me to patch it up!

Did you notice that there is another air path short-circuit right where the fan touches the frame? You can actually see it in your picture. It's a result of the fan mounting mechanism: those rubber grommets prevent the fan from laying flush with the frame. Maybe it's an acceptable tradeoff for reduced vibration? I was trying to think of a simple way to close that one off as well. Maybe use the same McMaster rubber tubing around the 140mm hole in the frame? Might have to epoxy it in place though, otherwise it would probably get pulled off when installing the fan.

I haven't spent much time with the stock fan. I had a different motherboard when I first set everything up. That particular motherboard's fan control had the stock fan at higher speeds than I wanted. I didn't try any other 140mm fans, so I can't compare.

The 140mm NB is pleasing during normal usage. 1700 RPM is a bit crazy though. Originally I wanted this speed since it was going to be the only case fan. I'd like to do more stress tests and see if a 1200 RPM maximum would work.

That gap between the fan and the duct does bother me, especially since I made such an effort to seal all the other gaps! :D The Noiseblocker fan came with a nice gasket but it can't be used with the case's fan mounting holes. Maybe I'll figure something out.
