Then the variac is turned on to apply heat load and dialed in to W and the fans are adjusted to RPM.
The Crystalfontz is then used to monitor fan RPMs and adjusted to a good stable level and all 17 of the thermal sensors are also turned on to start recording air in, air out, water in, water out over those 17 sensors and the fan RPM.
All of these are then recorded each second and allowed to run and log temperatures for approximately 1 hour while carefully controlling ambient temperatures. After about 30minutes the data log is brought into excel and reviewed for stability and ambient results. After the system reaches stability while ambients are nice and level, the data is saved and trimmed and an average of the stable data is averaged.
This averaging includes the average of the fan rpms at the time of the test as well as all the temperatures. That data is then copied to the below chart to calculate the results. At that point the radiator fan speeds are increased to RPM and heat load to W and the test is repeated. Next the fans are increased to RPM and heat increased to W and data logged and extracted again. The most critical and difficult part of this is maintaining a constant ambient temperature.
This is why logging is used to evaluate and continue logging data if needed to collect a good data point. Simple things like someone opening the front door for a minute will cause a sudden drop in ambient and the test has to be redone. In a nutshell, I am spending a great deal of effort to review logged data and extending the data logging period as needed to ensure a good stable ambient temperature which results in more time per data point but a much more accurate data point.
