OK so i've had my watercooling setup running for a week now, and am very dissatisfied.
Its an external setup, with a 10gal res of tap water, a Maxijet 1200 submerged, ½" ID tubing, 5½"x7½" heatercore, and a Maze2 waterblock. The processor is a 1700+ Tbred B, running at 12.5x166=2088Mhz for a rating of 2600+ at 1.75v. My temperatures hover around the 40°C mark (measured by my EP-8RDA's sensor) - sometimes higher, like 44° in the morning when its really stuffy inside, sometimes lower, like 39° when i've left the window open for a while. Room temperature stays between 72°F and 76°F. The water is cool to the touch, even after running for days straight. I am using just the heatercore right now - when i have a fan on it (shrouded), temps drop around 3-4°C roughly. Why the bad temps? With this exact same setup but a 40CFM fan on my AX-7, i was getting the same temps, maybe a degree or two higher. What i want to know is whether i ****ed anything up to make my temps so high... with a shrouded fan like i have, they should be much lower, shouldn't they? And the heatercore is in free air so it should be giving lower temps than one mounted in a case. ![]() I used AS3 the first time and mounted the block without washers, with just the springs and the nuts. This time i used Chomerics 1641 paste and used washers to increase mounting pressure (taking due care to avoid crushing the core) The block seems to be on there pretty solid and i have used thermal paste before, so its not likely i messed it up twice... I'm using 10ft of tubing total - 5ft from pump to block, 5ft from block to heatercore (the outlet of the heatercore flows into the res) The flowrate is nothing to write home about - neither a trickle nor a torrent. What could be wrong??!??! ![]() ![]()

Always use the fan, shroud. Only use a very very small amount of AS3. To much of any thermal paste can be harmfull to temps. The biggest things with your setup I would think about changing is that submersed Maxijet, and that long 5ft tubing from pump to block. Find a way to shorten that. Those two things are hurting your temps worse than anything else. ![]() |
