Fan does not need to run continuously at 90%
Your merely creating a profile to allow for your GPU fan to run up to 90%, instead of the stock 50%
MSI afterburner or Cam PC monitor are both free.
Cost you nothing to try

My case has 3 filtered fans pulling air in, and3 fans exhausting including GPU fan.
Why would you push your graphics card fps beyond what your monitor is capable?
Your lack of wisdom coming through loud and clear

For got to mention. Only using 60 hz TV. So frame rate set to 60 fps through AMD Crimson. My frame rate holds constant 60 fps. If I take frame rate cap off . My frame rate jump to 75 fps

Negative.. graphics settings maxed out... underload, no overclock on my R9 290 temp 52 C.. I7-4790K CPU
Asus motherboard with 5-way optimization. CPU overclock to 4.6 temp 33 C
Like I said. GPU fan will only spin up to 50% stock
Can't keep up with the cooling required.
Using MSI afterburners or Cam free PC monitor to create custom GPU fan profile was I able to keep GPU temp under control

Nobody mentioned this, but MSI has a software program free called MSI afterburner. Basically allows you to create a custom fan profile for your GPU. Kinda was having same problem. Found that my GPU fan never spun up pass 50%.
Suspect this was trying to keep fan quiet.
Created profile allowing up to 90% fan rpm, selected temp range. Stopped display driver from crashing. While maintaining temperature
