Review on Noctua NH-D15S Dual-Tower CPU Cooler with NF-A15 PWM Fan - Premium Brown Edition by Agata Wydra ᠌

Took on 3700X. Normally, nothing seems to cool this percentage, but in comparison with the budget Arctic Freezer 34 CO - heaven and earth. The installation of the second valve immediately gave a minus of about 5 degrees while reducing noise, since both are now spinning more slowly than one before. Namely, at 100% load of 6 cores and the temperature inside the case is 28-30 degrees, the temperature of the cores is stable at 74-75 degrees (loading all the cores adds a degree somewhere). This is with a standard valve plus Scythe Kaze Flex 120 mm for blowing. Both valves are set to 40%, stock spins at 680 RPM, optional 800 RPM, both are virtually silent. If you unwind the regular one up to 55%, and the additional one up to 50%, the temperature will go somewhere in the region of 71–72, that is, not much lower. At the highest speed, in the “cosplay vacuum cleaner” mode, the temperature can only be brought down to 69. With the same staff in the medium-comfort mode (that is, the same 55%), it was possible to achieve 77-78 degrees. Prots, infection, at all these temperatures stubbornly holds 4.2 GHz. Up to 4.4 accelerates only when the load is reduced. It's for temperatures. In terms of geometry, this is an absolutely ingenious solution, it does not interfere with anything, it does not rest against anything. Mounts for valves at 120, that is, you can install round 140 (as a regular one) and ordinary 120. The second is better than 120, because otherwise it will run into memory. The mount allows you to move it back and forth as you like, but if you set 140 and move it up, this will increase the already considerable height of the cooler. The build quality is, of course, excellent. In the photo, the mother of the Gigabyte Aorus Pro V2, the Fractal Design Define S2 case. The same system, before and after installing the second valve on the cooler and two additional ones on top of the case.
