Hello to everyone who looked at this topic. This is my first description of the work on this forum, but not the first time at all. I'm from Russia and my knowledge of English not very good. By this do not be surprised if I do not understand your comment, or ask you to rephrase. No sponsors. The project budget is limited, using the materials that I already have. Therefore, no advertising will not be! I will begin with a description of the work already completed. Over a year ago I started working on this project. I had a little free time, so the progress of the work was small. Now my wife needs her own computer at home which occupies minimum space on the table. All components for the computer I already had, so decided not to buy notebook, and continue to work on the project. So. List of main components: MB: ASUS P5KPL-AM CPU: Intel C2D E8200 RAM: Kingstone DDR2 800MHz 2Gb Video: Gigabyte GV-R577SO-1GD HDD: Seagate 7200.2 200Gb (maybe more) At first, I decided to replace the motherboard northbridge heatsink. Here's how it looked originally: Low-profile heat sink was taken from another motherboard. In comparison: I decided to add a copper base to the heatsink. Copper base and raditor were individually lapped on the glass with fine abrasive paste: Then together: The radiator is ready for installation. The height of the heatsink from the board just 15mm.
