CPU waterblocks on Crossfire 7970+MCP655 Mod - Page 2

post #11 of 15
Thread Starter 
Thanks.

I haven't ran my GPU miners since I got the second 7970 because of a weird bug that mines on both cards when crossfire is enabled, and one card was air cooled so was crazy loud and hot. I could disable crossfire, but I'm too lazy to go back and forth with it and I only mine overnight since dual cards at full load for hours on end will heat up a room quick!

Real busy week and I was gonna finish it Tuesday but the second block wasn't in yet. I'll probably drill out the bracket and dremel the edges on the second block tomorrow after work, then put it all together and redo the whole loop Saturday. The cheap tubing I was using on the GPU loop started leeching plasticiser after mining 24/7, so I got some Tygon to replace it. I can see the slimy strands sticking to the divider in the res. Also, being ghetto I used red food coloring which faded away to a nasty cloudy pink in like a month LOL. Now I have some blood red Primochill Intensifier dye which is inert and made for WC loops.

Pump is going in the bottom section, but still debating whether I should mount the rad on the bottom as well with the two quads, or on top and move the drive bay to the top rear exhaust fan...

Haven't had time to post a real update, but after a few snags I do have it all together working amazing. After an Extreme HD Valley run my core temps on both cards never passed 42c, and VRMS were 59/54 smile.gif. Down from 55c with the modded H70, and 57c with stock H70. 15c cooler then a stock AIO mod.

Looks like I need more rad, after leaving it mining overnight on both cards, the water temp got all the way up to 39c(12c over ambient!) and core temps rose to 49c. Still cooler then the AIO, but a 280 is not enough radiator for dual overclocked 7970s under constant load. Will eventually replace the AMS dual rad with a third Black Ice 2 GTX 480 quad.

Realized I never posted a finished pic, but they are already installed so here is a quick pic through my side window of the bottom card. Bit of glare off the window, but you get the idea. VRM plate portion was cut out of the stock cooler, and fans are mounted above them. "Top" (middle, really) card has the same mounting but the DWood bracket under it for the fan, since it has the customized "Puck" lip on it. Both are cooled with the MCP655 going to an Aquacomputer AMS 280mm rad and Phobya res. Upgrading to a GTX2 480 eventually, since a single 280mm is a bit small and the water temps on the GPU loop get pretty warm with dual OC'd 7970s.
