I realised (just shy of my 42nd birthday) that I had not had a new computer since 2003 :o All of my systems over the time had been cobbled together from second hand parts or cast-offs from friends. As I want to get into racing sims with friends at work, I realised I needed a decent PC. I also needed to keep the WAF (wife approval factor) reasonably high so the system needed to be compact and quiet. To this end I chose a Cooler Master Silencio 352 Micro-ATX case after reading about is cooling capability and damped side panels. Here is Australia it's fairly well priced against rivals like the Corsair Obsidian 350D and Fractal R4 mini

The system is not as quiet as I thought it would be since the front case fan (connected to CHA_FAN1) runs at full speed all the time. According to the UEFI I should be able to slow it down - still researching that one

In my very humble opinion, your system isn't well thought noise wise.
Anyway, IIRC cha-fan 1 is a PWM header (4 pin), while CM stock case fan (a rather mediocre one) should be a voltage controlled one (3 pin): am I right? In case, you need either a new fan or a different header.

Or you need a fan mate.

I would ditch the intake fan entirely, and get a PWM fan for the rear exhaust. It will be 100% A-Okay from there.

Eventually you could upgrade to a tower cooler as well, with a better PWM fan for that as well. That said, at idle and under light use, the stock Intel heatsinks are very quiet. They always ramp up to 100% on startup, but after that, it's smooth sailing.

Your build looks pretty neat as it is. That case is pretty nice. Your height limit for the tower heatsink is about 160mm, for future reference.

Yes given the excellent motherboard PWM fan controls PWM chassis fans could be a better option for this case. And certainly the exhaust would be the prime position. However the Silencio 352 intake fan does blow air directly at the CPU cooler and graphics card, and for this reason a PWM intake/exhaust combination would probably be the optimum configuration. For a PWM fan I would recommend you consider the Noctua Redux NF-S12B 1200 rpm PWM which has a nominal speed range of 400 to 1200 rpm. Depending on the BIOS settings and ambient temperature this fan would idle somewhere in the 400 to 500 rpm range. The Noctua Redux NF-S12B 1200 rpm PWM from sources such as PC Case Gear should be around $20. As your motherboard has only one PWM chassis fan header if you decide to fit two fans then a PWM Y splitter cable will be required. For example the SilverStone PWM Fan Splitter Cable which is about $10 from PCG. I appreciate this adds up to another $50 Australian but it would give you a really quiet system under idle and low system stress conditions, and under gaming stress conditions the PWM fan(s) would automatically speed up to increase air flow and limit CPU and GPU temperatures (and fan noise). You would get a 'fit and forget' system but equally the BIOS controls would allow the fans to be fine-tuned if required.
