I have tried to use SpeedFan but nothing is working, I know there's a way to change the fan speed manually in the BIOS but I don't know how. The fan keeps shutting off while I play games and makes the game's frame rate drop massively as it heats up. Is there a way that I can force the fan to be on at full speed all the time?

I would however check the BIOS under hardware or something like that. What motherboard is it?

As I said, check the BIOS under hardware or something to that effect.

I checked and changed the fan control to manual but it is asking me to set the slope and I don't know what it means. It is currently on 0.75 and the max is 2.50
I don't know what that means or what to do

"Slope" must mean the temperature curve, check the manual from page 18 through 32 for any setting suggesting that.. or detailed information on the fan speed or CPU temp warning. I'll keep searching through the manual for any relative information.
http://download.gigabyte.us/FileList/Manual/mb_manual_g...
Slope PWM (page 23)
Allows you to control the fan speed. This item is configurable only when
System Fan Speed Control is set to Manual
Options are: 0.75 PWM value / ºC ~ 2.50 PWM value / ºC.
Based on the description of PWM (Pulse Width Modulation), the higher setting must be higher power applied to the fan motor for higher fan speed and more frequent intermittence between stopped and running state which should translate to cooler running CPU.

I'm looking at it but I don't understand what to set the slope to, would it be better higher or lower?

In any case, configure it to the higher setting, and use the computer, later adjust it to the lower setting and see the difference so you can adjust it to the best setting.

I just set it to manual and the slope to 2.50 and launched a game to check but it still stopped spinning but as soon as I exited it the fan started spinning againIts weird that it would stop running. Even when I am at 9C my PWM water pump keeps running at full tilt. Sounds almost like a motherboard issue.

I thought it was SpeedFan at first, messing it up but I've removed it now and tried changing everything but it still doesn't work, I don't know what to do next.

Games should not have influence on the CPU fan, but CPU heat they cause may... obviously a fan in good condition would not be affected.
My Advice:
1. Consider replacing the CPU fan
2. and meanwhile recheck the Silent Fan Speed Control in the BIOS settings... check it still is on Disabled.
3. Reset the BIOS and after that reset the Fan Speed Control to disabled.
4. A BIOS update would remove possible BIOS corruption.

How do I do any of those?

1. First off, check that the BIOS Silent Fan Speed Control is disabled so the ran runs at continuous full speed. If you have to change the setting, restart the computer, preferably turning it completely off, so the setting takes effect. Next open the case to visually check the actual fan speed against the BIOS setting. Play the game if necessary to recreate the actual conditions when the CPU fan fails, while visually checking the fan speed... If the fan keeps stopping, buy a replacement.. if it's a regular stock cooler fan, you can buy a replacement at any computer supply store or on the Internet. If it's a brand name specialized CPU cooler, see if you can get a fan replacement from the manufacturer or searching around on the Internet.
2. To reset the BIOS check the different ways you can do it.

3. A BIOS update: You can download the BIOS update from the motherboard manufacturer's product page, from the Support / Downloads page. The BIOS download normally include the instructions to install the BIOS update. http://www.gigabyte.com/products/product-page.aspx?pid=... Download the F10 version from the link that indicates your area of the world.
