Is it normal for the rpm of my stock Intel Fan for my i5-3550 to go up and down?
What i mean is according to Asus Suite II Sensor Monitor the rmp goes up and down between 1094 and 1229 and actually if i look close enough at the fan when my pc is on i can actually see it changing speed every few seconds is this a adaptive feature similar to my GPU?
This is simply a curiosity, and i hope someone can sate it for me
Yes. The fan speed varies according to the temp. Same for many good power supplies. Some motherboard bios have a calibrate function and optional settings after you finish calibrating. I set mine on "quiet" but your bios settings may be different.
