Thanks for that link, I've been watching that thread too. I used to search every day for new links but I'm satisfied the board is a good one. I'd really like to find a real review but there might not be any until there is another mini-itx socket 1156 board with onboard graphics out; like the Intel board. What I'd like to hear about are more low profile coolers that are used.
The i7 860 might still work with the original case, motherboard and video card if you downclock it or reduce the number of active cores in the bios. A high pressure exhaust fan like a
Noctua 120mm that can be constantly run at full speed and still be quiet might improve the cooling on the DFI board with the H50.
The i7 860 has a 95w tdp and the Corsair H50 should be able to handle the cpu cooling. In an HTPC case and with a liquid cooled processor I wouldn't be surprised about the rest of the system heating up. Frequently the cpu cooler is critical in keeping the air moving in an htpc case for more than just the processor. If the cpu wasn't hot the fan might be running at a low speed making airflow in the rest of the case even worse. For HTPC I prefer a low profile cooler that also moves air to the side of the cpu. Personally, I think the PC-Q07 really needs ventilation holes on the top of the case.
You still might be able to get the DFI board, GT 240, and i7 working well in a different case. Perhaps one of the Micro-ATX cases with better cooling where you perhaps wouldn't even need a low profile cooler. You'll probably need to air cool the cpu unless you get a case with much more airflow though. The
Antec Mini P180 or even the
Silverstone SG06 look pretty good. I'm a big fan of vents at the top of the case for small systems to make better use of convection cooling.
Unfortunately, for the socket 1156 I haven't seen low profile coolers that don't just blow air straight up or down. I'd really like to find one with the fan embedded in the fins that would, in my opinion, provide better airflow around the processor.
I suspect there are more coolers with 1156 brackets that just don't have the docs updated. This
Scythe "Shuriken" SCSK-1100, for example, isn't listed as 1156 compatible but the manufacturer site and user comments say it is.
Much of the time I end up trying several coolers and fans on a new build before I'm happy. I plug them in outside of the case just to get an idea how they sound and where the air goes at full power. I rarely use the stock fans for any cooler I get if they can be replaced. I have lots of spare parts. :-p
