It is unbelievable to be writing this, but I replaced the stock fan on the Wraith Spire with this Delta fan, and I am now able to overclock my Ryzen 7 1700 to 4.0 GHz (1.42V) in my small form factor RVZ02 case with the dust covers on. This may not sound like much but the stock fan was already at its limits at 3.6 GHz and CPU temperature was hitting 89 degrees. Now, the fan does hang over a bit by half centimeter in both directions but I was able to securely fasten it to the heatsink with a single screw on corner, and the temperature now reaches a peak of 69 degrees Celsius with IntelBurnTest after 30 runs at Very High which lasts about an hour and in Prime95 and small FFTs, I get maybe 65 Celsius. In real world gaming and video encoding tasks, I see low 40's. Idle is about 25 degrees Celsius or 5 degrees above ambient.
