I built a pc 3 days ago and I woke up this morning to turn my pc on for it not to boot up because of CPU temperature. I went into BIOS to see that my CPU temperature is 87 degrees Celsius.

My PC Specs are

AMD Ryzen 7 1700
Default CPU Cooler
16GB DDR4 2400 MHz
Asus Prime B350-A Motherboard
1TB HD
240GB SSD
Corsair CP-9020098-UK VS Series 650W
Corsair 275R Case ( Only 1 fan works )

If I was too add more case fans would this lower my CPU temperature?

Have you overclocked? If not then that sounds like a more fundamental problem than *not enough cooling*. Did you use the stock thermal paste? If not, what did you use? A stock 1700 should not really go above ~70 degrees, with the stock cooler, effectively regardless of case airflow. I would suggest checking that your fan on your cpu cooler is funcrtional, and that it has a decent fan curve and can operate at full capacity. If all is normal, check if your motherboard has any auto-overclocking style features, as they can increase heat and cause instability if not functioning properly. If even that is normal, you should clean and reapply thermal paste.

I haven't overclocked. I don't know how too. Before I reset my pc all was fine and then when I went into bios everything was messed up. I used default thermal paste and from what I can see my cpu cooler is fine. I don't know what you mean in regards to fan curves tho. With the motherboard auto overclocking style there is 3 options. Standard, Energy Efficient and ASUS Overclock. I have it on Standard.

I would suggest resetting your BIOS, which can be done by shorting the reset pins on your motherboard (I'm not sure if your case has a reset switch). You can refer to your motherboard manual to find out which pins are the reset ones.

Does your CPU and case fan rotate when you turn the PC on?

If they do and at a reasonable speed, then you may need to remove the heatsink, clean off all the thermal paste and reapply, just one drop of paste.

You may have used too much paste and not have a good thermal bond between heatsink and cpu.
