While waiting for the game Mafia II to arrive very soon I took the time to make sure that the Green Reactor 3D Test PC using water cooling for the processor and the video card(s) is ready to take on the challenge head on. The system now has two GTX 480 video cards working together in SLI, of course water cooled as well as the CPU in order to ensure quiet operation and very high performance… plus some overclocking of course. The good news is that the two 480s are enough to handle the game in 1920×1080 resolution, with maximum details, AA enabled, PhysX set to High and in stereo 3D mode on top of all that with an average framerate of a bit over 30 fps at any time according to the benchmark available in the demo. That is of course with the Core i5 750 CPU running on default frequency along with the two GTX 480s also running on default frequencies, and with a bit of overclocking for all of them like 4 GHz for the CPU and 840 MHz for the GPU and 4468 MHz for the GPU things are looking much better with an average framerate of almost 40 fps. And hopefully the final game will be even more optimized and perform even better than the heavy benchmark built inside the recently released game demo, and I’m not going to have to wait much longer in order to be able to confirm that. Meanwhile, are you ready for the Mafia II challenge on your hardware in order to play it with max details, PhysX and in stereo 3D mode with 3D Vision of course… did anyone actually get a dedicated video card for the PhysX?

As I’ve mentioned a few days ago the new Green Reactor 3D Test PC is ready and functioning with just a few minor things been tweaked and changed/fixed, mostly related to the appearance and not the functionality. And of course the good question that arises here is how well does the custom liquid cooling does its job in keeping the CPU and the VGA cool enough, so here are the temperatures of both. The two components are being cooled in a single loop with the water first going through the CPU and then through the GPU water block. For really stressing both main components I’m using LinX for the CPU and FurMark for the GPU running with everything to the max and even 32xAA active to really push the video card to the limit…
The processor being currently used is Intel Core i5 750, a quad-core CPU with idle temperature of about 34 degrees Celsius and it goes to around 50 degrees Celsius in about 20 minutes and stays at that temperature after that. This is with an ambient temperature of about 30 degrees Celsius and the fans not running at 100%, but at 60% instead to be really quiet, which still providing really good airflow and cooling performance.
The idle temperature of the GPU is around 42 degrees Celsius with 30 ambient temperature in in about an hour of serious load with FurMark its temperature rises up to 71-72 degrees Celsius max and pretty much stays there after that. If the cooling liquid did not go first through the CPU block and then through the GPU block the temperature could’ve been lower, but even this way it is still very good. Silent operation and around 25 degrees lower temperature as compared to the loud air cooling and the high working temperatures reached with the same level of high load otherwise. If staying at default working frequencies the voltage of the CPU could be further lowered while the card continues to operate flawlessly, up to something like 0.86V the temperature drops with about 10 degrees under maximum load of the GPU, and that is something that you should do if you do not intend to overclock the video card.
