Review on Noctua NF-A9 PWM: Premium Quiet 4-Pin Fan (92mm, Brown) - Efficient Cooling Solution by Adam Browning

A few weeks ago I bought an NH-U9S for my CPU and decided that instead of a single fan I needed a push-pull fan system on top of the heatsink. So I bought this fan as a second fan. This fan is of excellent quality from Noctua and is identical to the fan that came with the NH-U9S. This fan has a Y-cable that comes with the kit. This cable is needed in my case because now I can connect both fans to the same CPU fan connector. The only other option was to connect one fan to the CPU fan header and one to the CPU OS header, but the OP header runs at a constant speed, which I didn't want. rear case fan. When I received this new one, there was a problem. This fan should be placed on the right side of the sink as an exhaust fan. The only problem was that the RAM got in the way, so the fan itself sat on top of the RAM sticks. It doesn't matter which slots they were in. So I had to remove and reinstall the headgear from bottom to top. This configuration worked like a charm and now nothing is blocked! The CPU temperature is between 28 and 35 degrees Celsius when idling, around 45-55 degrees Celsius under load, but no more. No complaints here after rotating the head orientation.
