What happens to the temp when the fan kicks in?
The issue with the 100C factory cut-in is, by the time the fan kicks on the engine is already heat soaked. The fan will only cap the temp there, it is not sufficient to bring the temps down by any significant measure. I have seen temp drops of ONE degree per minute, until I got to 35-40 mph again.
What should I do if my fan temperature is too high?
If the temperature inside the fan housing can exceed 1,000° F, installing proper insulation is vital to controlling bearing temperature. Ball bearings generate less heat than spherical roller bearings, but changing from spherical roller to ball bearings requires conducting a load analysis to ensure adequate L10 life.
What should the operating temperature of a fan be?
Operating temperature is another important consideration in maximizing the reliability of fan bearings. The operating temperature of roller bearings should never exceed 200° F. Excessive temperature damages bearing components, particularly the cages and seals, and degrades the lubricant. The four sources of heat that normally affect bearings are:
What should the CPU temp be when idle?
Noticing spikes in idle temperature 50-70+ C with no load. Normal idle CPU temp is avg 38-40 C. Performed a quick scan and temp shot quickly to 80 C. In my opinion CPU should not have gotten that hot. The fan will “take off” anywhere from 20 seconds to 2-3 minutes (with varying speed) and many times when the system is completely idle.
How does a fan affect the air temperature?
If the supply fan is downstream of the cooling coil in a draw-through configuration, the fan heat increases the supply air temperature, increasing the supply air volume required to meet a given space load. If the fan is upstream of the coil in a blow-through configuration, the fan heat is absorbed directly by the coil.
Do you include fan heat gain in cooling load?
Fan heat is a significant cooling load that must be included in the cooling load calculation. Supply fans produce the largest heat gains, but heat from return fans and mixing-box fans must also be considered if these are present in the system.
What should temp be when cooling fan does not come on?
NOTE: if the cooling fan doesn’t come on when the engine has been operating for 20 minutes or more, make sure that coolant is reaching operating temperature, around 220°F (104°C). You may be dealing with a stuck-open thermostat.
How does a fan affect a cooling coil?
If the fan is upstream of the coil in a blow-through configuration, the fan heat is absorbed directly by the coil. In either case, the fan heat adds to the cooling coil load.
