I just put together an EX58a UD5 based machine. The CPU cooler is a Thermalright IFX-14 hooked up to two connected Arctic Cooling AF 12 PWM case fans that are connected to the CPU_FAN.
The BIOS (just flashed to F2c) has CPU SMART fan-Enabled & CPU SMART FAN-PWM.
Although the Fans are running (apparently at full speed), the BIOS as well as EasyTune and Speedfan 4.0 list the fan speed at 0 RPM. No matter how I set the PWM Advanced mode in EasyTune5->Smart, the fans just keep rolling on. How do I get the PWM function to work properly?
The I7 920 at default values runs at idle CPU 32|Core32/30/32/29. At 100% the values are CPU 47|Core54/54/53/49.
As an aside, although this is not my first computer build, it is my first experience with an aftermarket cooler. The installation of the IFX-14 was difficult and necessitated the removal of the ends of two radiator leaves to make room for the Corsair Dominator memory I'm using, a large long-nosed set of pliers was necessary to plug in the ATX_12V_2x, the PCIEX1_1 slot is covered up and not usable, the DDR3 memory in the first slot cannot be removed, the DDR3 also interfered with some of the fan clips so I had to resort to cable ties to place the fans and the business end of this monster cooler was convex. If I ever have to take this cooler off, I will replace it with something smaller and easier to install.
