Looking forward to seeing Brickhead in Decembers stats. I noticed he has fired up his GPU again  |

Looking forward to seeing Brickhead in Decembers stats. I noticed he has fired up his GPU again Yes, the weather turned colder, and I have a room where direct electrical heating is the only option. Non-productive space heaters just seem wrong... Unfortunately, one GPU coldplate had sprung a leak (and the PSU sits at the bottom), so there was some tinkering and loop re-routing to be done before the liquid-cooled rig could contribute. |

never trusted myself to have anything to do with liquid inside my PC - scares me to death  I remember the guys at liquid ninja's who built that weird pc that was submerged in some sort of gel/gunk, they knew how to push the boundaries  |

I believe the LN folks used vegetable oil. Perfectly pure water would work better, but only with perfectly clean components and not for long, it takes very little contamination to make water conductive. I sort of agree with the hydrophobia, but the choice of graphics cards pretty much force my hand. One air-cooled AMD 7990 (dual 7970) in a perfectly ventilated chassis (side panel off in a cool room) is barely able to balance on its thermal limit when in use. Longitudinal coolers (radial fan at one end, hot air out the other end) aren't made big enough for two Malta/Tahiti/New Zealand GPUs (375 W), and transverse coolers (two or three axial fans) recycle hot air locally. Close the door, or raise the room temp to T-shirt level, or put more than one card in the same chassis, and there's no way around liquid cooling. Newer, more energy-efficient GPUs you say? Alas, those are all severely limited in double-precision (64 bit) FP performance.  |
