Thanks for the pics, do you know if the panel fan will fit due to the height of silver arrow dissipator?
I guess that top fans fill fit.
I see that he has removed the original fans of the graphic card, do you know a thread with more pics and tests about this mod? I plan to buy a Sapphire Radeon HD 7970 Dual-X
I believe the side fan vent is over GPU not CPU so should not be an issue. But removing the side and top vent covers increases noise and changes airflow even if no fans are in them. My experience with this build and several others is with other PCI slot covers removed and 3x good intake fans using PWM control requires at most 1 exhaust... the rear vent. Case temps are 5c or less above room temp... usually 2-3c
My Define R2 has bottom and back vent grills removed with 3x TY-140 fans; 2x front intakes and 1 bottom intake are PWM controlled by CPU PWM signal. Side and front top vents have stock covers.. only back top vent cover is removed. No exhaust fans at all. I do have a duct (sides and face, mobo side open) from back of cooler to back vent and I/O cover is removed for exhaust of airflow over motherboard. To lower mobo temps I built a box vent under CPU cooler with cutouts for heatsinks & front cooler fan below cooler. This allows the front cooler fan to blow air into "box" and out through the mobo heatsinks. NB was 56c max before (still plenty safe) and now it's 51c max. CPU and case fans idle 700rpm@26-28c and 100% on 6x cores rendering graphics they run 950-1050rpm@44-50c. Temps in case are 1-3c above room and never more than 4c above room.
The build in pics has a VTX3D Radeon HD 7950 X-Edition V3 cover removed w/2x Arctic F12 TC case fans with sensors between PCB and cooler. Was 70c with stock shroud & fans, now 50-60c, ultra settings, 60fps unless particularly detailed cut scenes.
You may have seen this before... I've posted it many times but as it applies to your case (no pun) I will add it again:

There is much more to cooling than the CPU. Modern GPU's make more heat than CPU... and getting that heat out of the case can be a challenge.
Setting up the case to cool properly is the hardest and most time consuming part of a build... And the most neglected by most builders.
Putting fans in case as intake and/or exhaust is only the first step. These fans only move air in and out of case.
This does not mean heated air is not mixing with cool air.
Nor does it mean cool air is going to where it is needed.
Getting the air to flow inside of case properly is even more important. We want cool intake air flowing to components and heated air from components flowing out of case without mixing with the cool air and warming it up.
How we manage that is what determines where the air flows inside the case. We can do this several ways; deflectors, cooler intake fans, exhaust fans, removing vent grills, using fans with higher pressure/airflow, building ducts to or from CPU/GPU cooler, etc.
Using a remote temperature sensor to monitor what air temps are is the key to finding out where the cool air is flowing and knowing heated air is not mixing into it. By monitoring this we can than make changes to get airflow the way we want it.
I monitor the temps with a cheap indoor/outdoor wired remote or terrarium digital thermometer. Twist a piece of stiff insulated wire into the last 8" of sensor lead so you can bend it to position sensor where you want it... like 40mm in front of your GPU cooler/radiator intake.. to see what the air temp going into CPU / GPU cooler is compared to room temp. The closer it is to room temp the better.. Shouldn't be more 5c maximum, 2-3c is what I usually end up with after 30 minutes full load on both CPU and GPU.
