New build to replace my previous dual Xeon 5440 system for work. CoolerMaster HAF XB case Gigabyte GA-Z77X-UP5 TH planar board Intel i7 3770 Ivy Bridge processor (non K - need virtualization!) 16GB Corsair Vengeance RAM @ 1600 Mushkin Chronos Enhanced 256GB SSD Western Digital Black 3.5" 1TB HD for mass storage EVGA GTX560ti 2GB GPU LG 12X BluRay burner Thermaltake 850W modular power supply Antec Kuhler 620 closed loop liquid cooling system For the cooling system I replaced the stock CM 120mm front fans with Cougar PWM fans controlled by the planar board I also installed two Cougar non-PWM fans on the Kuhler 620 in push-pull configuration bringing cool air into the case from the rear and exhausting it vertically out the top of the case via a 90 degree duct. In testing, I tried a single Cougar on the radiator before adding the second. The additional fan lowers Prime95 torture test temps 10 degrees C without adding a significant amount of noise. Overall the system is VERY quiet - I can barely hear it on my desk less than three feet away. The PWM case fans spin up a bit under heavy load but it's still quite livable. I hate noise! Temp wise, the CPU never goes above 60C according to CoreTemp while running Prime95 for hours. The PWM fans respond to the chipset temps and spin up after a few seconds then spin right back down when the CPU load is removed. At idle and during normal light use like web browsing, the CPU stays at 28-30C. I didn't bother adding 80mm fans to the lower level - temps down there never get anywhere near warm. The heat from down there rises up the sides and finds its way out anyway. Benchmark wise, my old dual Xeon ran Geekbanch 2 64 bit about 12,000. This 3770 system runs it a little over 18,000 which is a noticeable improvement. I really like the HAF XB case. On my desk it looka a little like the ED-209 - squatty with an attitude. I'll add external pics tomorrow when I get to work. Only things I plan on changing are adding 16GB additional RAM and a NZXT black perforated card reader to the lower optical bay.
