Dell r720 2 u server change water

Time:12-01

Mention dell r720 a lot of people say it's the garbage, but I think can also, after using the graphics card whether apply colours to a drawing or 3 d drawing, after all I use enough, fan noise is a little things that are not and very worry about heat dissipation, so he moved to change the idea of water and the experience of many twists and turns, but finally managed to change water,
One, planning waterway, N the design, but finally picked a mistake the most complex solution, if let me start all over again, I want to won't use this solution,


Second, custom related accessories,
First is water, water is ready to use 3, 60120, for the first, water is a little complicated, gave up, in the end, the two 60120 cooling water to graphics, custom made a 60 * 380 * 27 drainage to give two CPU heat dissipation,





Followed by CPU cool head, also drew N kind of figure, feel good people say bad processing, the last and chose the most simple,





Other accessories, can be taobao,


Three, assembly parts,
Assemble CPU water: modified fan first, put 6 6025 purchases add to speed, and the purpose is mainly fan speed to deceive the server, if not the, after add graphics card fan has been turned at a high speed, the noise is too big, the added after the proposed speed can pass a fake speed signal to the mainboard, let the fans don't have to go so fast, in order to ensure the cooling effect, I chose four wire fan, the fan power pick out a quasi speed, at the same time to fit the rotational speed signal received speed, speed line or receives fan, fan or with the original adjustment function,





Then put the original fan to be removed, and pull down the inside of the fan frame dampers, which terminates and modified good fan in, finished products are as follows:






Assembly graphics water: the two 60120 water drainage mouth cut shorter, two water between two 60 fan, corresponding with three sets of water mouth, cements,








CPU cold welding head,






Modified flow rate meter and thermometer: because the server installed don't know whether the inside of the water in the flow, this is necessary, is to meter the LCD display of the thermometer removed, by fly line from the front panel,






Three, began to assemble: nothing said, according to the planned waterway is installed









Sheung shui, cover




Four, boot test
Boot normal use after two hours, with the big niang pressure test for 10 minutes,









Five, some bits and pieces,
The entire waterway in the double pump, completely no problem, I tried to use single pump installed double pump, but now that let him both to work, two pumps, a velocity of thermometer, two video card fan of water, from the back of the disk array take electricity mouth take electricity, to turn the fan interface, a line a no spot is customized, 45 yuan a piece, because the water go too complicated, it took a lot of energy, if let me again, won't go, so simple point, don't display card water, also need not four mouth dual CPU temperatures, also with a single pump, in that way, it is much easier,
