Photos: building a Sandy Bridge PC

Summary: We needed a testbed PC running Intel's latest-generation Core i7 processor, so we built our own. Here's how it turned out.

  • Installed in a brand-new (also top-of-the-range) Intel DP67BG motherboard, this Sandy Bridge processor needs a new 1,155-pin socket, one fewer than the previous generation. Intel's argument for the change is that the new architecture is too different to make compatibility worth maintaining and that the performance increase is worth it. The DIMM sockets, supporting a maximum of 32GB of DDR3 memory up to 2,400MHz, sit right next to the CPU as you'd expect, while at the bottom you can just see the first of the two PCI-E slots. The header at the top of the photo supplies the CPU fan, while the one lower down supplies the rear chassis fan.

  • This view of the motherboard shows the general arrangement of components. Note the two blue PCI-E x16 slots, which are separated by enough distance to fit a pair of double-width SLI-enabled graphics cards, and the trio of PCI-E x1 slots. At the bottom sit six outward-facing SATA sockets — two of them 6Gbps-enabled, the rest 3Gbps — and an eSATA socket. The on-board RAID function offers RAID levels 0, 1, 5 and 10.

    Under the 'Desktop Board' heatsink lurks the P67 chipset, which provides what Intel calls the Platform Controller Hub. There's a single Gigabit Ethernet socket, support for 7.1 audio, 14 USB 2.0 sockets and a pair of USB 3.0 sockets on the back panel. Also noteworthy is the 'Back to BIOS button' on the back, which forces the board to power-on to the BIOS menu using default values while retaining previously saved changes.

  • This shot showcases the Noctua NH-C14 heatsink and its six heatpipes with dual 140mm fans, which are very quiet in operation. The system includes two sets of cables that slow the fans' spin speed from 1,200rpm to 900rpm or 700rpm. This promotes quietness, and a 140mm fan shifts a lot of air — 110.3 m3/hr at 1,200rpm, 83.7 m3/hr at 900rpm and 71.2 m3/hr at the slowest 700rpm setting. We used the 900rpm setting and the CPU temperature hardly shifted from 33 degrees C. Despite the overhang of the fans, we managed to install memory modules with the heatsink installed, although you could probably take the lower fan off to make DIMM installation a bit easier, as well providing greater noise reduction while retaining plenty of thermal headroom.

  • Update: We will, of course, be keeping an eye out for the SATA II bug in this system's P67 (Cougar Point) chipset

  • Jeez thats a massive heatsink lol! Typical of a big company like Intel to make such a small error :(

  • The heatsink IS pretty big, especially for a 95W part, but it'll cope easily when this extreme version of the chip is computing flat-out.
