Alienware M17x R2 loud fans

My M17x R2's fans are running very loud. I re-applied thermal paste on the CPU and both GPUs but no luck regarding the noise. Also I'm concerned about the temps on my CPU, the program I am using is 'CPUID' and 'REAL TEMP' and both are showing all 4 cores of my CPU are fluctuating between 70 C and 90 C....

I noticed the left fan on my left/main GPU isn't working, could it be possible the other fans are trying to compensate for the one that is broken?

My main concern is my CPU temps being so high even after applying new thermal paste on all the heat sinks and dust busting everything.... The programs temp fluctuate so fast between 70 C and 90 C its hard to even say what the consistent temp is.

UPDATE:
Heat issue solved (I think?), I fixed the wired connection for the left fan and it's working now. Temps are consistently under 60 C now. As for the loud fans, they are running much more quiet now. I've been told loud fans when gamming is common with the m17x r2 and that higher than average core temps are common as well.

Here's a screen shot of my temps currently can someone tell me if they are good?

 

It all seems to be working fine now. The fans are loud depending on the temperatures that it is reaching, that''s why now that the temps have dropped, they noise has also dropped.
