One big question to you:- your sig rig points to an EVGA GTX570 having non traditional cooling (ie with a central fan and the card exhausts heat bi-directionally via the front and the rear = pic 1) while your pictures above seem to show EVGA GTX570s having traditional cooling (ie front centrifugal fan with uni-directional exhaust via the rear = pic 2). Which is yours?
If you have the non traditional cooling ones, this is another big reason why your GTX570s are having high temp inside a RV01 because the hot exhaust from the card's front just runs against the uprising fresh air, resulting in ineffective heat dissipation. If so, then a HAF-X with its side panel fan should bring a higher improvement.
If you have the traditional cooling ones, then the HAF-X 's VGA duct could also be very helpful to direct more air via the front.
However, given the bolded numbers above, it is hard to say with certainty whether the improvement would be 10C+. I think it is highly possible because your are currently seeing a 5C improvement when the side panel is removed. So, with the additional help of the HAF-X side panel fan and the VGA duct, another 5C is quite likely.
(I suppose if you do get a HAF-X, the RV01 will be sold to recover some money and so the net will not be $200)
Lastly, if you have an extra 92mm or 120mm fan, perhaps reconsider my previous suggestion of using such a fan at the top of the RV01 to facilitate the airflow exhaust. You do not have to cut anything. No permanent 'damage' at all. Just remove all the unused PCI slot covers for better air movement. The fan can be fixed with double sided Scotch tape or adhesive epoxy or Blu tack.
I have the gTX570 that matches Pic2.
There are so many EVGA GTX570's if you go to newegg, like 10 of them. All the same but light differences. Mine has the fan offset to the end blowing air out the rear.
i HOPE Someone else finds this thread if they need help but I wentinto EVGA precision and actually went into the options and turned on the "FAN PROFILE" Setting where the fan increases in intervals such as:
50% fan speed - 50degrees
60% fan speed - 60 degrees
70% fan speed - 70 degrees
etc.. and so on.... same 10 unit intervals parallel...
WELL, My cards aren't getting hotter than 70C on 100% load gaming 1920x1080 on HIGH SWTOR with both panels on.
WOW. The fan speed gets to 70% and its a little louder but totally fine and aceeptable.
I was using the custom profile before but never knew you could get it to do step intervals like that off the EVGA precision program.
I'm just going to keep it as is I guess - I'm really happy and happy I bought EVGA cards for their warranty and 3rd party software.
So other than that, I'm going to move on to overclocking my CPU - couldn't be happier, just hoping running the fans at 70% won't kill the fan. then again , these have lifetime warranty
