Probably best to lower the wattage setting to 180-ish Max Watts (at least for that loop). 120-125 is the overheating area.

As per philipma1957 page:

Temp Front / Back T,B
33 °C / 72,67 °C
Fan Speed
40
Start Voltage
0.62 / 0.62 / 0.62 / 0.62
Max Voltage
0.67----------------------------- try 0.63
Max Watts
180 / 180 / 180 / 180

I can't see the photos as this site f'd them up.

sp20's should run under 1400gh more like 1300gh forget the ratings of 1650 to 1700gh.
