Is it possible to remove the shroud?
Usually they either clip in and/or are attached with a screw or two.
If that's the top of the case, you'll need to turn the fan round so it vents out.
This looks like the front of the case. The reason I say this is because you already had one fan at the front, yes?
If it is turn the top fan the same way round as the bottom fan.
I think you have the photo's mixed up as this is a photo of one fan and probably the top of the case.
If it is the again turn the fan around so it's extracting out.
Let's get your fan set up sorted first but in any case stick to the method that is currently stopping the crashes.
Thats great.
So the one placed at the top needs to be the other way round so it extracts out.
Lastly when you take a photo can you pull back a little so we can see which part of the case being discussed as it saves on confusion.
Now you see all those cables you have? You can, when your feeling up to it, tuck them out of the way. See where the other cables are going round the back? You could always follow that route if there's room.
This isn't super critical but it makes for a nicer looking machine and the airflow isn't impeded.
Yup your right, great job! Looks nice lit up too.
Looks really good. Nice one.
Ah ok so are they running at 100% do you know or at a lower speed?
Well I think with that controller you plug it into the cpu header, then plug all your fans into it. Whatever the fan speed is set at via the cpu header will determine the fan speed for all fans plugged into the controller.

If your fans are at 100% chances are they'll be very noisy, is this the case (re the noise)
Yes..
As long as your temps are fine then all is good. I didn't want you sitting there with the fans driving you nuts so I'm pleased to hear they aren't doing that..
So, now getting back to your gpu, do you still need to back the clocks off?
