Is This Thing On? Noiseblocker's NB-Multiframe at 750 RPM
Let's say your passively-cooled PC does end up in a room where it gets a little warmer than you'd like every so often. Installing a fan is inexpensive insurance, and it'll give you peace of mind that your hardware isn't baking itself. Noiseblocker's NB-Multiframe M12-S1 is an excellent choice for such an application because it’s not even audible from 50 cm away in an absolutely quiet room.
This fan should be used with its included vibration isolation pad. And there’s just enough space between the CPU cooler and the back of the case to accommodate this exact model.
You can plug the NB-Multiframe M12-S1 into the system or CPU fan connector. It really doesn't matter which you choose, since the cooler doesn't support PWM, and our chosen motherboard doesn’t offer simple voltage-regulated RPM control. None of that matters though, since running full-speed at 750 RPM is perfectly fine.
BIOS Trick
If you're using a PWM-capable fan, some motherboards can turn them off when they aren't needed. The feature looks like this in the BIOS:
The platform keeps the fan from spinning until a CPU temperature of at least 55 degrees is detected. This way, you enjoy complete silence under typical loads. We don't recommend pushing a target any higher than 55, though, because AMD's APUs are more sensitive to heat than Intel's CPUs.

Much appreciated.
1. undervolting the CPU and GPU
2. underclocking and farther undervolting the GPU for 2D mode
3. hybrid cooling setup for GPUs where the fan only turns on at a high temperature (may require GPU BIOS editing depending on GPU model)
OPTIONAL (due to risk): removal of CPU IHS
But otherwise it's a neat article, personally I would sacrifice dead silence to use a cheaper HDD and perhaps more of those silent fans if I were to build one myself.

The main issue is the GPU, and that would require a hybrid passive-active cooling solution much like was done for the CPU, but for some reason they didn't even try such a thing...
By the way, I own two of those Samsung Blu-Ray drives and the blue LED in the button is overly bright. I would NOT want to set that case on my desk.
great article toms
