Today I looked at the temperature on rb4011iGS + rm in idle 34 C. And on rb1100ahx4 the temperature is 40 c with zero loading. The rb1100ahx4 case is barely warm. there the radiator does not touch the hull, but in a dream it seems it should still be hot. Who checked them at 100% loading cpu? What ar...

You can reduce the frequency by going to system-> routerboard-> settings-> cpu frequencu. When installed at 800 MHz and the 2.4Ghz WiFi is turned off, the temperature should stop at 37 C. This is idle. But I do not know how it will affect performance.
