  1. I have done the volt mods too several 9700pros....first thing to remember is that some oc well and some hardly at all. I am running under normal conditions (gaming).... 1.92v vcore 3.19v vddq 1.75v vdd core=452 mem=364 agp aperture set at 32mb (different for each mobo) agp frequency @ 70mhz fast writes on video ram cache disabled agp8x enabled agp spread spectrum disabled (important on some nforce 2 boards) score= http://service.futuremark.com/compare?2k1=6534407 cooling: swiftech mcw50t, large swiftech radiator, acrylic bay resevoir, 4x120mm fans for the radiator, swiftech mcp300 pump, and a dedicated 320watt mean well peltier psu. Here is the info on doing the volt mods....you dont have to use fixed resistors....as a matter of fact I would highly reccomend using variable resistors and set them to the values in the article to start. That way you can adjust them to your liking or to accomodate your cooling. One thing they dont mention is that you cant set your resistor for 1.6v and then use your bios to adjust from there adding 1 v to the bios figure....for some reason this doesnt work. You will also notice that in the article they got their radeon much higher then mine......I dont know how since they are using just h20.....could be variations in the cards. Dont be impatient and be sure to test step by step only adding voltage when you need to. Stop once in a while to check the temp of your water block or if you use a pelt then carve a spot for a temp sensor in the side of the cold plate. Something else that I have done is to make a bracket to hold 1x80mm fan above the top of the card and below to cool the ram. The ram seems to be held back more by quality then cooling though as I originally used 2x80mm delta big boys and noticed no change from using 2 70mm ys tech magnetic fans other then noise! Here is that site and let me know how it goes...... http://www.xbitlabs.com/articles/video/dis...erclocking.html
  2. yes, you are correct.....which is why on most superbikes there is no fan or if there is then the fan only kicks in while below a curtain speed. Obvoiusly this only works to an extent.....as far as aircooling a radiator goes....assuming your ambient temp is 70 degrees then you accelerate that by either causeing a vacuum within the fins of the radiator or a blowing through the radiator. No matter what though you will always have a point where more doesnt neccessarliy mean better. That is why more people either lean towards commercial chillers for their resevoirs or phase exchange coolers like the prometeia. You could chill the air running through the radiator but then that would be so inefficient that its not even worth thinking about. :-)
  3. First here is where you can find your parts.... http://www.cpufx.com Before you purchase from them though I must warn you....they definately take their time in processing and delivering. Sometimes up to a month. Checl reseller ratings.com and you will find that most people get their orders but not within a reasonable amount of time. Secondly, the diameter of the tubing is not as imperitive as the speed of the flow. Most people think that having the fastest pump will benifit them in some way. Well, not true! If you can slow the water to increase absorbtion then you will have more heat carried from the processor. A half inch system can outperform any other so long as you have a slow pump. Remeber that the mass over the chip will be a large determining factor in how much of the heat will transfer within a given amount of time. Clearly a half inch system will place more mass over the chip at any givin time. Most people make the assumption that the water is to cool the waterblock and keep the chip cool.......but it is really to absorb the heat and continually move the heat away allowing the chip to constantly transfer its heat to the waterblock. http://www.docmodgod.com------homepage not a store!
