Only one Fan is really working

I just bought a hp pavilion 15-bc018ca laptop. I noticed that when using the speedfan application it says I have two fans. However, when playing games like witcher 3 only one fan speeds up to around 4500+ rpm but the other fan only goes from 100 to around 300. Is there something wrong.

A few other questions I have:
1. are temperatures of around 80C going to shorten the life span of the i7 6700hq?
2. is a fan speed of 4000+ rpm going to end up ruining the fan?
 
Solution
1) SPEEDFAN may not be accurately reporting things, or applying profiles if you try to monitor.

100RPM to 300RPM does not sound correct for any laptop fan. 4500RPM may be correct, though that would be pretty annoying likely.

2) 80C is okay. Intel recommends mid 70's for "optimal" life of the CPU. It won't throttle down until around 100degC.

3) Fan at 4500RPM ruin it?
Agreed, but it mainly depends on the QUALITY of the fan. Presumably the laptop manufacturer chose specific parts that wouldn't wear out in a reasonable length of time (and again it may not be an accurate number).

All fans wear out, and if it spins to 4500RPM presumably there was a need for that so the fan is designed to run that high (and should have a rating that says...
1) No. Its maximum temperature is 100c, and the rest of the laptop will likely crumble around it long before it dies.

2) Eventually, yes, but I'm sure the fan was designed to run at that speed for a certain number of years. Laptops are disposable, eventually it's going to crap out.

Regarding your speedfan reading, it's probably just a false reading. Most of speedfan's displayed data for my motherboard is nonsense.

Well the laptop does definitely sound loud enough to be going at 4500RPM. How do I find this rating? I've looked through all the papers that came with the laptop and looked up the laptop model on hp's official site and other sites that sell the product. They didn't seem to mention anything about the fan of the laptop (not much of a selling point I guess). I'm guessing Speedfan is probably not that accurate as the temps shouldn't instantly change when I do things (like from 70C to room temperature by closing something). Not to mention the fact that task manager says that at most I'm only using 30% of my CPU which probably shouldn't heat it up too much. At the very least I guess the fan is doing its job since the laptop itself feels very cool to touch other than a few small areas and the fan holes.
