    With a 92mm cooling fan you can probably cool both video cards.

    It's important to mount the cooling fan securely so that it can't accidentally make contact with any cables, wires or anything else inside your case.

    No offense but that has to be the worst case of cable mismanagement that I've ever seen!

    Can any of the cables be routed behind the motherboard?

    Can you remove the empty upper 3 bay cage to mount an additional fan aimed at video cards.

    I have an infrared digital thermometer and found that the video card's pcb gets quite hot.

    More food for thought:

    Take a look at how I installed my AIO push/pull fan setup with one fan mounted on the outside of my HAF XB computer case.

    Yeah that's a good idea and I'll see what u can do with wires when I'm changing the motherboards over, and the top three weren't empty, have ssd drives in there but I could sort something :)

    Installing a second 120mm front panel fan should help.

    A web search using: computer case cable management will provide some excellent guides.

    Drive cages restrict airflow even when they are empty.
    It looks like your drive cages are riveted to the case.
    You should be able to route most of your psu cables behind the motherboard tray where you can use cable ties and/or velcro to secure the excess cable length.

    ~~~~~~~~


    Cable management examples on the web from an image search using computer case cable management:













    Other options for your computer case that might provide better cooling:
    • fan direction, such as top fans for air intake with front panel fans for exhausting air
    • radiator location on the top
    • mounting ssd's vertically behind the motherboard tray

    It goes without saying that twist ties or cable ties should be used to keep wires and cables against the case panels so that they don't block airflow and don't increase air turbulence.

    With my push/pull radiator/fan setup the VRMs get better airflow and heat can't be trapped above the VRM's and under the radiator and interior fan.
    I've had good results using a fragrance softener dryer sheet as a fan filter when I've used top mounted case fans for air intake.

    Does it take a lot of time and effort to optimize cable management? YES!!!

    Yeah I'll definitely do it properly when I change the motherboard over just waiting on delivery now :)

    Also I have looked into mini inside case fans to have one on memory cards and getting a more powerful fan for the front I still think having the top two fans as exhaust fans is a good idea though because as we all know heat rises so it will get rid of the heat faster drawing it out the top, may even drill holes in the case window for a side mount fan, I work in fabrication so it should be a simple enough job?? I really am taking in what you're all saying and trying to get the best out of what I have got, so thanks for all the help guys, and corsair said that ram should be fine with the motherboard so soon as it comes I should be up and running :) I could put the side mount fan right on the graphics cards is my idea or see if there is room to put two 120mm fans because I have 3 fans spare what you think? Would be cool air from outside case and I have looked at the case and sorting the wiring shouldn't be an issue, I just never thought of all that, first time building a beast machine ^.^ last one I built was mediocre and it lasted me 3 years ^.^

    Common sense is good, but you also want to keep an open mind to alternatives that might work better. You are engineering a setup that will provide you with optimal cooling for your cpu, VRMs, graphics cards and memory.

    With positive internal case pressure some of the heated air will also be exhausted out of the unused, vented rear I/O panel slots and this will assist in cooling your video cards.

    Using an infrared laser thermometer will help determine if any of the components are too hot.

    Measurement Range: Between -50 C and 380 C (Between -58 F and 716 F): Amazon.co.uk: DIY & Tools



    HWiNFO is an excellent monitor tool for voltages, temperatures, and other system information and you can optionally save the information to a log file.

    MSI Afterburner offers an excellent saved graphic monitoring feature that you can review after gaming or running video stress tests.

    The motherboard has finally come today, will be installing it and doing the fans and wires tomorrow, this weekend I finally get to play! Will let you know how it goes guys, overclocking the gpu's first and let you know how that goes too see if I can get some screen shots etc.

    Check out HARDOCP - Overclocking - XFX Radeon R9 285 Black Edition Video Card Review where Afterburner was able to increase gpu voltage.
    YMMV, your overclock might be higher or lower.

    A reference Radeon R9 285 has a base GPU clock of up to 918MHz and a memory frequency of 5.5GHz. The XFX Radeon R9 285 Black Edition ships with a factory overclock of 57MHz on the GPU clock and a factory memory overclock of 300MHz for a 5.8GHz effective rate.

    For our overclocking efforts, we started by increasing the voltage to +100mV (the maximum allowed) and power limit to +20% (the maximum allowed) and began increasing the GPU clock speed. We were able to get into games at stable both 1175MHz and 1200MHz configured as the GPU clock, however, at those speeds the PowerTune functionality kicked in and throttled the GPU speed down, varying between 1075MHz and 1150MHz during the course of gaming. As our sessions went on, it settled in closer to 1100MHz. Through further experimentation, we discovered that the power limit was the limiting factor on the overclock and causing the GPU to throttle down from our desired speed. In order to combat this, we tried reducing the voltage in increments of 10mV to see if we could free up some power to allow the GPU to run at a solid 1175MHz. The lower voltage helped us to achieve higher observed clocks within games, but it also became unstable. Even dialing back to 1150MHz with a reduced voltage resulted in a rather prompt crash. Next we tried 1125MHz with the voltage pushed back up to +100mV and found that it would generally stick to 1125MHz throughout game play. We did notice a few instances where it would throttle down to 1115 to 1119MHz, however, this only happened in a couple of games and we deemed it a success.

    Our next step was to begin increasing memory clocks. We started with a modest 100MHz (200MHz effective) rate boost within MSI Afterburner and quickly began noticing artifacts as we were playing. We bumped it down a 50Mhz (100Mhz effective) and the artifacts disappeared allowing for stable game play.

    The final overclock of the XFX Radeon R9 285 Black Edition achieved an observed GPU clock increase of 150MHz over stock clocks and a memory increase of 200MHz GDDR5 effective rate.

    With the increased power limit and voltage, we observed the GPU ran about 5-6 degrees Centigrade warmer than it did prior to being overclocked with the fans spinning significantly faster. The faster fan speed was noticeable on the test bench, however, it was not distracting during game play.

    Below is a screenshot of MSIs Afterburner and GPUz after achieving our maximum stable overclock, which will be used as the operating frequency through the rest of the evaluation as a fourth video card.

    From their conclusion:

    Overclocking

    The XFX Radeon R9 285 Black Edition turned in a decent 15.3% overclock above its factory default configuration. However, when compared to the stock Radeon R9 285 clock speeds, the maximum GPU overclock speed represents a 22.5% increase over the reference clocks. We were a bit disappointed to hit what seemed to be a power wall during our overclocking sessions. We believe if there was enough power available at 1175MHz or 1200MHz to maintain the voltage at the maximum level, then the card may have been able to game at those speeds. We ended up with a final GPU clock of 1125MHz, a 150MHz increase over factory overclock. We were also able to increase memory 200MHz to a 6.0GHz GDDR5 effective rate.
