  1. My recent project DIY CPU water cooler. I'm not desperate to overclock my pc, but want to make it to work quiet. First I'm going to replace CPU heatsink/fan with heat exchanger , if this is going to work, a graphic card will be next. I've managed today to cut out 2 parts of heat exchanger from 12mm aluminium plate.

    job for tomorrow: to cut out cooler mount ( I don't have any alu plate apart of 12mm so I have no other choice than to use 3 mm steel plate)

    Looks nice, will be interesting to see how well it performs. I think it would be better to have thinner channels and more of them, but I'm sure that whatever you do will be far better than most air cooling systems.

    What are you doing about getting the area where the block contacts the CPU smooth? It needs to be a very flat surface to work well.

    I'm thinking of making one at some point. You can simulate the heat flow very nicely in solid works without too much effort. What socket is yours?

    brings back memories, i used to overclock my PC's when i was younger, and had full water cooling to keep the noise down.
    May be better to make it out of copper and also lap the underside to get it as flat and smooth as possible.

  4. I have Intel Core2 6400, 2.13 GHz LGA775 Socket. Heatsink is original Intel supplied together with CPU. It's wholly aluminium. When running with few aps on average CPU temp is about 50C. After light 400 grit wet sanding a contact surface I would risk to say is more smooth than original heatsink.

    There is some more pictures & details of this project at my website:

  6. Finally a clear pipe arrived today. I decided to try gravity circulating cooling system before I start to mess with any pump. At the moment of writing this a computer is on for more than an hour. Temperature of CPU is 33C. CPU usage is about the same like last time picture. So for now full success :dance:.

  7. When you get time can you run IntelBurnTest v2.50 and report your CPU temps?

    This will really test how good your cooling is.

    I'll, but to have precise cooling capability comparison I would have to use this program with old heatsink as well. For temp check I use ASUS AI Suite- program supplied together with mainboard. 2h 15min of running a comp and temp is 37C, but I believe as a result of water heating up in a water storage tank(3l plastic bucket).

  9. I've attached two DS1820 temp sensors as pics below(below black tape) to measure temp of in and out coming water from cooler.

    That's a water temp readout shown in 0,1C.
    Top line- Outlet
    Lower line-Inlet
    While pics below taken CPU temp - 42C

    I've run this test @ standard stress level,5 times to run. Max CPU temp reached 59 centigrade in a peak (when started this test the comp was running for nearly 10h non stop since morning). Is my cooling any good then?
    Few issues appears:
    1st- Top surface of the CPU is not perfectly flat
    2nd- Average temp of the chipset is higher than 55 centigrade with standard heatsink.
