Want this question answered?
IF the fan speed in RPM is given, multiply this figure by 60 to find the number of rotations the fan makes in an hour.
the best angle is "45 degree" because the air speed coming out of the fan is giving by this equation V=v.tanθ were : V: air speed,,, v: is the blades speed and we got the maximum of the speed by making the angle 45
The fan blades.
At least half.
the fan has stopped completely and the laptop should be serviced before there is heat damage
Not enough information. Length of UPS run time required.
Fan regulators are similar to light dimmers. Their function is to control the speed of the fan. The regulator uses resistances for the speed of the fan. It acts as a divider and the speed changes based on the resistance.
same as low speed relay its call fan mode
This fan has three speed settings, low, medium and high.
cpu fan speed of 3590 RPM normal(CPU 73c)
with a variable speed switch
Could be a bad fan motor resistor
There are three speed settings for this fan and it rotates 90 degress.
now when you say replaced heater fan multi speed are talking the fan or the switch because ther is a fan speed resitor that can go bad and fan only works on high speed which can cause conector to get very hot and cause insolation on the wires to melt and cause a short in the harness making fan run constantly.
There should be a smaller plastic box behind the fuse box in the engine compartment. There you will find the high speed fan relay as well as the low speed fan relay.Good Luck
no need to check, just replace the whole fan that has a little control module in the fan itself to control the speed as well
A fan or cooler relay is used in electrical furnace to change the blower speed to the blank speed for cooling
