macros1981 Posted May 21, 2005 Share Posted May 21, 2005 Had a trawl through all the posts in this section but cant find any info with regards to changing the stock fan on the Hydro cool 200EX, is it easy? anyone got a quick guide or recommendation as to what fan to use? Seems pretty easy just wondering if anyone has done it and can share their experience I was also thinking of adding an inline speed control for real low revs and quietness, again anyone any experience? Been a frequent reader of this forum but never joined, be kind i am a newbie. Thanks in advance. Link to comment Share on other sites More sharing options...
macros1981 Posted May 22, 2005 Author Share Posted May 22, 2005 No-one? Tried just turning off the fan to the radiator, temps do rise but not as much or as quickly as you would think, makes me wonder how lower revs i can get away with. Link to comment Share on other sites More sharing options...
KaptCrunch Posted May 23, 2005 Share Posted May 23, 2005 you an use a reo-stat or a resistor on the fan line, or go geo-cooling if want silent cooling Link to comment Share on other sites More sharing options...
macros1981 Posted May 23, 2005 Author Share Posted May 23, 2005 you an use a reo-stat or a resistor on the fan line, or go geo-cooling if want silent cooling Whats geo cooling? surely not this, sounds wacky, http://h2othouse.com/html/geothermal_cooling.html Put a resistor on the line, sounds so much better for very little drop in performance, even tried running with no fan for a while but a couple of hours really gets the water temperature up though! Any recommendations for a nice and quiet fan, seems to be a lot about, any suggestions? Link to comment Share on other sites More sharing options...
KaptCrunch Posted May 23, 2005 Share Posted May 23, 2005 yip thats it but no mistifirer just ground coolness cooling your burried heat exchanger, also fanless, using water pump an water blocks Link to comment Share on other sites More sharing options...

Seems pretty easy just wondering if anyone has done it and can share their experience Macros1981, If you would look hard enough, maybe after a few hours :biggrin: , you would have found these threads here ... :biggrin: http://www.houseofhelp.com/forums/showthread.php?t=25865&highlight=fan http://www.houseofhelp.com/forums/showthread.php?t=26357&highlight=fan http://www.houseofhelp.com/forums/showthread.php?t=27127&highlight=fan The detailed information about the HydroCool fans and mods are all around this forum. The fan is screw mounted into an aluminum fan shroud. Just do not over tighten the screws since the shroud has press fit PEM fasteners. Too much torque will strip the PEM's out. The fan plugs into a front display PCB connector header. It's under a glob of hot glue. You could either spend a bunch of time picking at it VERY CAREFULLY and avoid breaking anything, or just splice out the old fan and re-splice in the new fan. Or, keep the old fan and splice in your speed controller. A Digital Doc +5, an EnerMax or CoolMaster would be a good choice for a control panel. Doing an "advanced search" under a "topic" word(s) using an author name like Bio-Hazard, Morrisgs, Clevor, and Eva2000. This will save you many hours doing searches in the forums. Also, narrow the search by picking the "Water Cooling Products" sub-forum. The searches will run faster too! :sunglasse Link to comment Share on other sites More sharing options...

Clevor Posted May 26, 2005 Share Posted May 26, 2005 The OEM fan in the unit is a pretty stout unit (2500 rpm I believe). The only fan worth changing for is the Sunon from Newegg that runs 3100 rpm, but it's noisier. One big advantage of this fan is the hub is smaller, so there is less of a dead spot in the center of the radiator. I would install one of those speed controls so you can drop the rpm if you like. Maybe this fan has too much airflow, too close to the radiator, and might not work so good without a shroud. Link to comment Share on other sites More sharing options...
