Review on 💨 Cooler Master Hyper T2: Compact Dual-Looped CPU Cooler with 95mm Fan and Copper Heat Pipes for AMD Ryzen/Intel LGA1151 by Donotello Figueroa

I wanted to build an "almost" silent PC that didn't want to stay fanless, but I wanted the fans run so slow (or turn off) during normal operation, which was quiet, and only during intensive operation did the fans increase performance. I bought this Hypter T2 CPU cooler as it is the largest Cooler Master that fits in a standard case and then replaced the fan with a Noctua NF-A9 and am very happy with the solution. I'm giving 4 stars instead of 5 because I had to replace the fan, but I would still recommend doing that instead of buying the much more expensive Noctua CPU cooler. This saves about $30 even if you buy an extra fan. Why did I have to replace the fan? Because the Cooler Master fan sucks and won't let you lower the fan speed below 32%. I was very upset because I didn't know why he wouldn't sink so low. Was it the fan controller on the motherboard? Or a software fanatic (either in the BIOS or in the operating system itself)? But after much debugging, I finally determined that the Cooler Master's internal fan controller was to blame. It stays at around 850 rpm for any PWM setting below 32% including zero, but once it goes above that it increases the correct speed to a maximum of 2500 rpm. I have a small workaround. To give you a little more control if you want to stick with the default fan: switch your fan controller to DC fan mode. In constant current mode, I could reduce the fan speed to about 500 rpm at 32% (3.84 V), and if desired turn it off completely, which the fan *NEVER* allows in PWM mode. It's really frustrating that the stock fan doesn't allow for this control and I wonder how many people blame their fan controller without realizing it's the dumb fan's fault. So I would suggest buying a Hyper T2 and then replacing the fan. for Noctua NF-B9 (yes, B9 instead of A9 which I use as it's cheaper and works just as well). the rest of the system, as well as the EVGA Gold power supply in "Eco mode". I have a really quiet PC that a fairly sensitive dB meter can't tell it's on. I have to test in the middle of the night because even cars driving outside can be detected. But at 3am it shows 21.1dB with PC off and 21.1dB with PC on. My stomach gurgles and this stupid thing goes up to 24dB, or I click the mouse and it goes over 30dB, so believe me when I say the dB meter is sensitive enough to take pretty small readings . To eliminate noise, the fans run at 13% on the back of the case, 10% on the CPU, and 5% on the GPU, with the front case fan off. But it's enough for airflow with good heatsinks, so the system temperature stays around 40 during normal operation, while the CPU and GPU temperatures stay in the mid-50's.

Other companies have unnecessary 2-pin fans. Also note that I replaced the fans included with Noctua NF.-B9 as their fans were noisy when overclocked.) -2 of 4GB DDR4 2400 Kingston Fury DIMM-Samsung 960 EVO M.2 SSD EVGA 650 GQ power supply in Eco mode
