AMD Ryzen 7 2700X Review: Redefining Ryzen

Thermals And Noise

The Wraith Prism

Ryzen 7 2700X's Wraith Prism thermal solution is a large, high-finned cooler with four flattened heat pipes and a plate behind them for stabilization. The heat sink's entire contact surface is thus made of copper. Its fins are arranged in such a way that the exhaust air is focused toward the memory and I/O shield.

The fastening clamp is a big disadvantage of this large cooler, which takes us back to the old Athlon XP days. Even at maximum load on all cores in the stress test, the CPU only reaches a maximum temperature of 82.8°C (corrected value), so it remains below the thermal throttle threshold. The cooler handles the 105 watts easily. You can expect peaks up to 70°C and a little above, depending on the motherboard's predefined fan curve.

The cooler is loud and emits 44 dB(A) under load (50 cm distance, 45° diagonal) when the fan is spinning at 2600-2700 RPM. The fan can even be a bit noisy even when the system is idling on the Windows desktop. Unfortunately, the fan adjusts much too rapidly as the cooler reacts to short-term temperature jumps.

We see the result in the narrow-band frequency spectrum of the motor noise, which shifts back and forth between approx. 240 and 300 Hz. The fan generates almost 39 dB(A) at idle, which isn't necessary. It helps if adjust the fan curve to a fixed speed of at least 1400 RPM if the processor is under 60°C. However, you'll have to experiment because each case will require different settings.

AMD has made good progress with XFR2 and the powerful cooling finally pays off in terms of performance. The power consumption remains largely the same and you get a nice clock rate increase, but we don't like the unnecessary noise levels or the fiddly mounting mechanism.
