    I ahve a gigabyte 3d Aurora case, Usually my gpu's idol at around 78-82'C however today i took off the side panel for about 20mins and the temp dropped to 60'C, i have 2 8800gtx in the case and i they do get fairly hot at times.
    Does anyone think its safe to leave the side panel off when gaming?

    Or even better if i were to install a 4th fan in the computer how would i go about powering it, retro fitting it is no problem as i have my ideas!!!

    If you've no power headers left on the board, you can easily get adapters to connect them to the 4 pin drive power connectors instead.

    i know this isn't really answering your question, but with a rig like that would you not consider investing in a liquid cooling system??

    An example (don't actually buy from Overclockers though)

    Not a good idea. Sure, lots of us have done it lots for ease of access, but it doesn't keep it cooler. If it did, the game rig makers would put mesh side panels on machines.

    Basically the airflow inside a machine is (/should be if building from scratch) designed to pass cool air over the hottest parts of the machine. Any extra openings, will only slow down this airstream.

    If your car was overheating, you wouldn't fix it by removing the bonnet

    not at all...just don't overfill the resevoir. leave room for liquid expansion. my buddy learned this the hard way.

    You can pick up a splitter cable in Maplin & just put it between one of the existing connectors on one of the big fans.

    Wow.It has been a while since me modding and gameing days but that seems kinda high. Am I wrong?
    Any chance of a pic of your the inside of your case.
    If you temp is dropping by 20 degress with the side open then there must be a problem with your air flow. Either your intake/outflow must be screwed up.

    totally off the point here but that's not bad for a phone!!

    anyway...have you considered the liquid cooling?? a rig like that would be very easy to hook up an well worth it.

    Well if i do go liquid i think im only gonna do it for the CPU, i heard that taking the fan off the GPU invalidates the warrantly which isnt an option. However thats where my problem is. if you look at the picturs the bottom gpu is really close to the bottom of the case and thats where the heat is, when i take off the side panel it can escape no problem...

    Would a new CPU fancooler do a good job considering how much cheaper it is and less hassle!
