I think maybe you need to be administrator to set affinity. I know that Folding@Home sorts its own affinity and that asks for administrator rights when starting.

Gaming performance post: Will be updated as I run tests.

i can tell you I'm already satisfied with how well this system performs. It's no quad-SLI powerhouse but it more than meets my needs for gaming.
Heat Issues (Click to show)
There are definite heat issues with the video card in this case. When playing video, streamed or otherwise, it is not an issue, but when playing Skyrim, I could hear the fan getting very loud as it reached toward 100% speed. I had Hardware Monitor running in the background to keep track of temperatures, and when I exited the game, I saw that temps had reached 81c on the GPU (processor temps on the other hand, were surprisingly low). I removed the lid and ran the game again. No audible increase in fan speed, and after exiting the game, Hardware Monitor showed nearly 20c difference in max fan temps. Unfortunately I think this means I definitely need to get ventilation cut into the side of the case where the GPU fan is located.

How are the temps on the 7750?
Confirmed this tonight, it does not extend beyond the motherboard at all, seems to be lined up perfectly.

Results of this were a bit more acceptable. Only ran it for 10-15 minutes or so, but it seemed to be leveling off just above 80 degrees. This was with the top off the case, but the top doesn't seem to affect the processor quite as much as the video card. In fact some benchmarks show the top on giving the processor lower temps. I'll have to look more in to that...

GPU temp of 81C while gaming isn't in itself a problem, I'm guessing it's the high fan speed that bothers. If you are thinking of cutting a hole in the side, try first making a test lid out of cardboard, and see how the fan reacts. Try also making a shroud to channel air directly from the lid to the fan.

Love passive builds. People these days are too afraid of high temps. As long as it's stable, there's no need to worry. Intel has safeguards for actual thermal damage. We have servers at work that stay at TJMax for months at a time.

I wasn't too worried about the 81c temp, more about the 92c temp during the MSI benchmark, although I suppose that is apples and oranges. The sound does bother me a bit, but only because I know some simple ventilation could help it quite a bit.. The fan on this card is quite small, so the whine at high speeds can be pretty annoying. I don't know if there is room to fit much of a shroud. There is very little room above the GPU to route anything, and it would have to route over it and to the back of the case where the ventilation is. I'll see what I can work on though. The cardboard idea is interesting, I will have to try that... Side view showing lid clearance (Click to show)

Wi-Fi miraculously got better today. Still not where it should be (my Galaxy Nexus pulls 13 down, 9 up, for example) but it's definitely better than it was.

I'm with you 100% on that. This has been something i've wanted to do for a while. Wish the card could be passive as well but I think I would have to sacrifice too much power for that. It is completely inaudible when watching movies and surfing, and sound from games will mostly drown out the video card, so I should be happy with it.

Quotes snipped for clarity.

Since you have no other case fan, the hot air coming off the heatsink has no reason not to be sucked back around in front of the fan. This is because the fan is the only place causing negative pressure. If you make a cut in the side next to the fan, putting a shroud between the fan and case wall will ensure the fan is getting cool air only. With the shroud, that negative pressure will be displaced to outside the case, and the overall effect will cause the inside of the case to have positive pressure and exhaust through the holes on the base and elsewhere.

Ahhh, thank you for the clarity, that makes considerable more sense than what I had been imagining tongue.gif

Hi guys,

I hope it is not to rude to interrupt your thread. I've a big problem with my Streacom FC8 EVO and ASRock H77-ITX:

There is not enough space for the internal USB 3.0 cable under the heatpipe:


I haven't measured it exactly, but only half of the space that would be needed is there frown.gif

Looking at your pictures with your Z77E-ITX the placement of the USB 3.0 Header looks way better. But you didn't connect them right? Did you forget to order the internal USB 3.0 cable or where you suffering the same problem like me? (Btw. the placement of the PSU looks way better!)

Best Regards,
Robert

Hello XBMC Fan, not rude at all smile.gif

I actually couldn't find a short USB 3.0 header cable. Is yours shorter than 50cm? If so, can link me to where you ordered yours? I looked at pictures of the H77 board... that definitely seems to be an issue since it is much closer to the CPU socket than on the Z77 board.

All of the header cables I've found, even the kind that aren't female-to-female, all have a lot of hard plastic above the connectors; although I'm not entirely sure why, as I've seen some USB3-to-USB2 cables that appear to be heat-shrinked, which would be a lot more flexible. I wasn't able to find any right-angle adapters, but even if one existed, I think your PSU connector is too close as well. You might try taking your current cable apart, and/or seeing if you can cut away the hard plastic that keeps the cable from being flexible. You can see from the picture on this page that the connector itself is fairly small.

What CPU are you using? If it has a TDP of 65w or less, and depending on what you're using your PC for, you might try removing one or two of the heatpipes on the right (over the header connector). The old version of the FC8 was only rated for 65w and less, and came with only two heatpipes.

Last but not least, Streacom has a Thermal Riser that can be used to raise the heatpipes higher. Here is one German site that sells it.. More can be found on Streacom's list of places to buy. This actually might be the most efficient solution, but probably also the most expensive. Might save you from ruining your USB 3.0 cable though...
