There are adapters but they're usually not worth the cost since you can usually get a better fan to begin with after tacking the cost of the adapter on top of a fan. https://www.amazon.com/Pocaton-Female-Socket-Connector-Cooling/dp/B073XJV5L9/ref=asc_df_B073XJV5L9/?tag=hyprod-20&linkCode=df0&hvadid=241963357402&hvpos=1o1&hvnetw=g&hvrand=1768550020676952586&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9032039&hvtargid=pla-465213213731&psc=1#customerReviews

I have a Artic F8 80m fan that has only 3 pins on it.

I am getting a Dell Optiplex 990 and thought it would be better if I replace the fans that game with it with better ones.

The motherboard fan headers are pwm and could be adapted for 4pin pwm fans. 3pin fans don't have the built-in pwm ic to modulate the incoming 12v on the 2nd pin nor the 4th pin to receive a pwm signal so they'll run at 100% rpm if sent a pwm signal. 

I'd recommend seeing how the stock cooling performs before deciding on whether or not to change any of the fans. Dell's prebuilts tend to already have optimized airflow.

So I just got my fans finally, and turns out the fans on the computer that I am trying to replace are 5 pin fans not 3 pin, can anyone help me find a adapter that has a 3 pin male to a 5 pin female? Or does it not matter and I can just hook up the 3 pin fan to the 5 pin on the motherboard?

What mobo? 5pin connector is proprietary, and usually used in prebuilds. There are no adapters. So if younneed to either connect fans directly to PSU or get hardware controller, like Grid or Commander Pro.

Yeah, you need to get hardware controller if you want to control those fans.

What hardware controller do I need and how would I set it up?

You can get either one with knobs, or USB connected one. USB ones use software and fan curves. Most notable ones are NZXT Grid (CAM as software) and Corsair Commander Pro (used to be Link). There might be other ones, but I'd need to do some digging to find out for sure.

He just run them with DC, no worries, it's like running PWN without that "fine tuning"

That might work with software like SpeedFan but I don't think dc control is normally available from Dell's motherboard settings.

And new gen motherboards, like my MSi mpg z390 ace, i can switch on all headers from AC to PWM
