It might be normal, really it depends on what the fan model and what is normal for that fan in terms of idle and maximum RPMs.
While that RPM does not seem particularly high for a laptop fan, if it WAS high then this means that either there is a problem with the thermal sensing capability on the laptop, whether due to the fan controller or the thermal sensor itself, has failed, and is defaulting to full speed operation, or the CPU itself is actually overheating because it has been thermally degraded, or there is dust and dirt built up inside the unit, or the thermal paste has become dried up enough that it is not longer working effectively, OR the fan itself has some kind of issue but it would seem unlikely to be the fan itself since the RPMs actually seem pretty normal in terms of being pretty middle of the road for a laptop fan.
My guess is that either in the BIOS, or in the Windows advanced power plan settings, there is a setting which is set to active cooling policy rather than passive cooling policy, and to be honest this is probably preferred. If the fan level is DIFFERENT than it used to be and you've made no changes, then I'd recommend getting a can of compressed air and blowing out the dust from each vent in the sides or bottom of the unit. Alternatively you might consider taking it to a repair facility and having them thoroughly clean any dust out from inside the unit and then remove the old paste between the CPU and heatsink and replace it with fresh paste. This MIGHT be something you can do yourself if you are very handy, and highly technically inclined, but it is not usually an endeavor for those lacking experience or are faint of heart. It's easy to completely ruin a laptop by disassembling it. There are many ways it can go wrong for the uninitiated.
Knowing the EXACT model would certainly be helpful.
