Testing Methodology:

We are primarily focusing on the performance of each cooler at 100% fan speed and also when locked to 40dBA noise output. We will focus on cooling performance using a manual overclock with all-core frequency and VCORE locked to 5.2GHz/1.3v (AMD) and 5.5GHz/1.3v (Intel) and Precision Boost Overdrive performance.

• The test data is logged using HWINFO and the final 10 minutes of the data is calculated to find the average CPU temperature and CPU clock multiplier (AMD PBO Test) and then plotted in the charts.
• For testing, we use a 30-minute looped run of Cinebench R23 and record the steady-state CPU temperature at the end of the test. This ensures that the CPU has had ample time to warm up and reach a steady state under all of the coolers.
• The ambient is maintained at 19-21 degrees Celsius. Where there is variation beyond this temperature range, we add extra repeated tests to ensure consistency. However, this is well controlled now with A/C.
• We also test each cooler with at least two fresh installs (typically three) to mitigate the likelihood of poor mounting spoiling results.
• Ambient temperature and humidity are controlled via a mini split air conditioning system inside the test room. Ambient temperature is maintained between 19-20C, Temperature delta figures are shown in the charts (ambient temperature is deducted from the measured component temperature).

Acoustics

Let's start by looking at noise output as this gives us a good indication of performance based on the noise.

At 43dBA the Sudokoo SK700V isn’t the quietest of the coolers we tested, but considering the fan is running at high speed over 2100 rpm it is relatively quiet compared with other single-fan coolers. Only the be quiet! Dark Rock 5 manages under 40dBA at max speed.

Thermal Performance: AMD Ryzen 7 9800X3D

With the fans running at maximum speed and the Ryzen 7 9800X3D clock frequency and voltage fixed, the Sudokoo SK700V manages a very respectable 63°C over ambient average temperature which put its level with the Deepcool AK500 and just in front of the dual tower Thermalright Peerless Assassin 120 Mini, but only a couple of degrees off the huge Corsair A115.

Reducing noise to 40dBA gives us a great indication of the cooler's true performance. Again the SK700V does well here at 65°C over ambient, which puts it just in front of the Corsair A115, but only a few degrees off the excellent be quiet! Dark Rock 5, however, this is good performance from the SK700V.

In the PBO test the important metric is the clock multiplier as the CPU automatically boosts frequency to hit a target temperature.

The Sudokoo SK70V does very well here, producing the highest clock multiplier at 51.4x, which means the CPU is running 20 MHz per core faster than Corsair A115, be quiet! Dark Rock 5 and the Deepcool AK500, which is higher overall clock frequency but in the real world it wouldn't be very noticeable if at all.

However it shows that the SK700V is a very good cooler for AM5, especially so for the 9800X3D as it shows solid overall thermal performance while outputting relatively low noise.
