Watercooling

Three Dell U2711 27inch monitors - 8064x1440 resolution!

I have been running Eyefinity for a while over three screens at 1080 lines of resolution limited by a Samsung 1080 monitor either side of my Dell 2711 27inch monitor.  However I was able to upgrade the two side montiors to match the middle meaning the whole lot can now run at native reoslution giving a total of 8064×1440 pixels.

However pushing 11.6 million pixels around was too much for my Radeon HD 5860 video card, so I also upgraded this to two Radeon HD6970 cards in CrossFire (linked together so both cards share the workload).  While the two new cards were able to drive all 3 displays I found they got hot – very hot.  At idle running Windows 7 they sat at about 60c, however when running any kind of full screen graphics they burned at 84c!  Too hot to expect a long working life.  After reviewing aftermarket fan cooling solutions I decided this was impetus enough to bite the bullet and install watercooling, especially as the ambient temperature in the room itself can get well above 30c.

 

Outside view of Watercooled PCInstalled is a EK FC6970 V2 full cover water block on each video card, a koolance CPU-370 water block on the CPU connected to a koolance 360 radiator and koolance RP-1200 combo pump and reservoir.  Details of the equipment and installation are in another post, however the result is a whopping drop of well over 30 degrees when running hot.  Windows idel now sits about 44c and maxes out at about 50c when being pushed hard with full screen graphics.
