Some updated temp/energy readings

Apparently the thermal paste has cured, and now I'm able to run Prime95 on all four cores without it immediately hitting 100c+. Prime95 - Four Cores pic (Click to show)

I also ran both Prime95 and MSI Kombustor to measure maximum energy use at full load of both CPU and GPU. It never went past 121w. Kill-a-watt pic (Click to show)

With the new ventilation hole for the GPU, I'm also seeing temps max out around 71c while playing Civ5 or running MSI Kombustor, so upwards of a 20-30c drop. Civ5 Temps (Click to show)

Now the bad news... I'm getting constant crashes when doing anything power intensive. I'm really not sure what the cause of this... as I had zero issues until drilling the holes in the case on Tuesday. I even played for 10 hours last Sunday, with the video card hitting 100c almost the entire time, and it didn't crash once. I've ruled out the HD 7750, SSDs, and memory, so the only thing left is the CPU and motherboard. Unfortunately I'll have to wait some time to order either of these to figure out which one it is... in the meantime, I'm basically unable to play games for longer than 5-15 minutes or so :'( Once I get some spare cash, I will probably order an i3-3225, as that was my alternate choice of processors, and I'd be interested to see what differences there are between it and the 3570k in this system.

Probably because of the GPU.

No hole + hot GPU = GPU throttling and lower power draw.

Hole + cool GPU = No throttling and power usage goes up.

It seems to happen even when using the integrated GPU (7750 not even in PCI-E slot). Also, 120w is far below what the PSU is rated for, and when playing Civ5, wattage never goes above the low 90's.

Edit: Not sure what I did, but it's rock solid now... just ran Prime95 for almost two hours, 30 minutes of it I had MSI Kombustor running as well. CPU stabilized at 87c, GPU stabilized at 84c til I put in a piece of paper to act as a crappy shroud. This reduced temps to 79c. Enabling a -20% drop in AMD Overdrive's Power Control Settings reduced temps further to 70c (Kombustor was running the entire time I was doing this). Power Control reduction will reduce performance as well, but I can at least leave it low until I need more performance, to keep fan noise to a minimum.

Edit #2: put together a bit better shroud... if anyone knows any good ideas for a more permanent solution than construction paper, do tell!

New shroud is performing fantastically. Kombustor had a difficult time brininging the temps to 64c. Kombustor w/ Shroud (Click to show)

SpyderMS - what a great job you're doing here.
I'm just 2-3 days from building very similar machine. It's not easy to find passivly cooled chasis with high WAF smile.gif
I ordered:
Case: Streacom FC8 Evo (from caseking.de - shipping form Germany to Poland in 2 days smile.gif )
PSU - dedicated Streacom nanoPSU
MB: Asus P8H61-I
CPU: Intel i3 3220T (35 TDP)
SSD: Samsung 830 64GB
RAM: G.SKILL DUAL DDR3 2x2GB 1600MHZ RIPJAWS X CL9 FOR SANDY BRIDGE
Remote: streacom IRRC + Logitech Harmony Remote
Keyboard: one of those small Rii mini keyboards

Build is for XBMC machine ( to replace my xtreamer player in bedroom). I'm reading this tread with most interest cause I'm starting to think about expanding capabilities of my HTPC with graphics card for light gaming.
In bedroom I have also Xbox 360 buy it's really noisy. For single player gaming I could use my HTPC machine (Steam Big Picture + PC adapter for Xbox 360 controller).

And here are my goals:
1. either use passively cooled graphics card (but as I understand with this passively cooled Streacom case it could be risky?)
2. or use graphics card with fan AND switch from iGPU (used for xbmc purposes) to graphics card (light gaming). Why switch? Using iGPU with switched off dedicated GPU gives total silence during watching movies. Is it even possible? @ HDMI cables: one for iGPU and the other for graphics card?
3. maybe PCIe extension cable and graphics card outside the Streacom case? And dedicated "box" for this graphics card? Used ONLY for gaming?

What I'm trying to achieve is totally silent machine for xbmc (iGPU only? Passively cooled graphics card - rsiksy? passively cooled graphics card but outside the Streacom case?) and a little compromise during light/medium gaming (graphics card with fan but switched off during watching movies? graphics card with fan but outside the Streacom case also switched off during watching movies?)


Spyder MS can you attach photos of case with the shroud option? smile.gif
Have you tried switching between iGPU and AMD?

Maybe there is possibility (I know some notebooks have such possibility with Radeon graphics) to set up iGPU as a default graphics and AMD for chosen games. Can you check this?

Once again, great thread.

It's tough to say without trying, although it is true that, with no airflow at all, your passive card would essentially be baking in its own heat. That being said, so was my 7750 before I cut a hole in the side, and although it would get very hot, it worked, and didn't crash. The most powerful passive low-profile card I could find was the HIS Silence H657HJ1G. This is a 50w TDP card, which is comparable to the 7750 (in energy use only, not performance) which is 55w (75w max through Power Control). The one on NewEgg does not have the best ratings, but it's the only one I know of. Other than that you would have to drop to a 6450, of which there are a few options. The 6450 also is only 30w TDP, so it may be more suited to an environment with little to no airflow... however, I would not expect to game much on this card. You would probably be better off putting the money toward an i3-3225 or i5-3570(k) with Intel's HD 4000 integrated graphics. You wouldn't have to worry about the heat from these, and overall you would use less energy than by adding a discrete card. Alternately you could go with an AMD Trinity processor which for gaming, performs better than Intel's HD 4000, or if you can... wait for Haswell, which should double Ivy Bridge graphics performance.

I briefly thought about this as well, but when I'm watching movies, I can't hear the fan anyways. I sit about 8 feet away from my PC though, so perhaps if you are sitting closer, you might be able to hear it... but honestly it should not get very loud when watching movies. Using two HDMI cables may not be an efficient option either, as your PC will not likely switch to the one that is 'active' automatically, which means you would have to go through the trouble of changing it each time. You might be able to set up some kind of automation to do this with a simple press of a button on your keyboard or media remote, I'm not really certain...

This would be the very last thing I would choose, because it wouldn't be any different than putting the card in the case itself. The box would also need to be custom built (unless you spend a ridiculous amount of money for one of the few that already exist for use with laptops) and it would need a variable speed fan, which means more wiring, and the fan would always be on which would defeat the purpose of it being silent.

With AMD's drivers (and I'm sure nVidia as well) you can set up custom profiles that can be enabled/disabled via hotkeys, including enabling manual fan control. I have a profile for the default settings, one for 20% reduction in power, and one for both 20% reduction in power, and manual fan control set to 20%. At 20% I have a very hard time hearing the fan sitting two feet away from it. I think this would be your best option if you just want silence during movies. It won't kill the fan completely... but in my opinion it's close enough.

This shroud is merely temporary until I can figure out something that's fully contained on the inside of the case, and less made out of construction paper... but it works great for what it is.

My ASRock board has something called VirtuMVP, which among other things, allows you to connect your HDMI cable to the integrated GPU, yet it will use your external GPU when needed. You can manually select which programs will use VirtuMVP in the VirtuMVP settings. I have not done much testing with VirtuMVP at all, as I previously thought it was the source of some stability problems (it was not). I'm not certain, but I also thought that I read somewhere that connecting to the integrated chip and using VirtuMVP will give you less overall performance than if you connected directly to your discrete card; but that on the flipside, it would give you far more performance than only using the integrated GPU. Again, I've not done any testing myself to verify this... there may not be any performance difference at all, or it could be negligible... I really don't know yet... but it's another option that might work for you.

Nice! Do you have the option set in the BIOS for the Ultra Fast Boot for Windows 8? It's an option only for Windows 8, so I haven't tested it yet. I just assumed you must have it set if you're getting 6 second boot times. I'm getting about 15-20 second boot times with Win7, but I also have RAID enabled, which takes a few seconds on it's own.


For both of you... and others using this case, or other Streacom cases, I found a potential issue with this motherboard which I believe may be the cause of the instability of my system. The heatpipes are basically laying right on the northbridge heatsink, and are in direct contact with it. I noticed after a crash that my CMOS battery was hot which was kind of curious, so I tried touching the northbridge heatsink and it pushed down, as if it wasn't fully in contact with the chipset beneath it. I realized that the heatpipe could be heating up the heatsink more than normal, causing the thermal paste to become soft, and at the same time, pushing down on one edge, causing the other side to come up off the northbridge, as it's only held down in 3 corners instead of 4 (and obviously not very well). I'm going to see if my computer stays stable providing pressure is put on the heatsink, keeping it flush with the northbridge. If it is the problem, I'm not sure how I will fix it, since the bend in the heatpipes is right there... would not be easy to bend them over the heatsink... might have to file the heatsink down frown.gif

Hello,

First, SpyderMS nice build men! You are in the limit with this case! Congrats.

I've built a computer with this case, the Streacom F8 EVO, it's awesome but I'm having some issues too. But firstly, I'd like to describe the components I chose to use:

1. Asus p8h77-i
2. I3 3225
3. Pico psu (150 watts)
4. Kingston 4gb ram memory
5. Crucial m4 ssd 128 GB

The temperatures of the core are around 60ºc (not Fahrenheit) when I’m using the XBMC, but with the Aeon skin (for those that doesn’t know this is a heavy load skin), this temperatures are ok for my, I set up the limit on 72ºC, the problem I found is on the motherboard, because the temperatures rise up to 60ºC, and this is the limit that the Asus suite sets to the motherboard, I’m getting worry. Someone has any ideas on that?

P.S. Sorry if I haven’t express good, English isn’t my first language

Hello Zirbio, the processor's temp is 60 or the motherboard? If just the processor, then you are perfectly fine. The maximum operating temp for Ivy Bridge is 105c, which you are well below. Even my Core-i5 has hit 105 before but the processor has built-in protection that drops the clock speed in order to not rise above that temperature.

Edit: it has not hit 105c in this case using the heatpipes... wanted to clarify that.
