ls1_alex Posted May 23, 2005 Share Posted May 23, 2005 Emailed Cool Guy and have not heard back for a week. Tried calling Tech support but cannot get a person on the phone. Hoping maybe a Moderator will see this post and help out. I own a Hydrocool 200ex and now with summer coming it is starting to constantly tick and hiss as the temps go up to 36-38. Below those temps it is very quiet and keeps my PC fairly cool. It is not low on water, the hoses are not bent, and the air filter is clean. This only happens at those temps.. I still have about 4 month of warranty on this puppy and hope to get this resolved before it runs out. Any suggestions would be appreciated.

See these forum threads here: http://www.houseofhelp.com/forums/showthread.php?t=28391&highlight=cavitation http://www.houseofhelp.com/forums/showthread.php?t=26776&highlight=cavitation http://www.houseofhelp.com/forums/showthread.php?t=25580 http://www.houseofhelp.com/forums/showthread.php?t=27475&highlight=cavitation Peace!

ls1_alex Posted May 24, 2005 Author Share Posted May 24, 2005 Thank you for the info Stev, some of the links you gave me describe the exact symptoms I've been having. Can't wait to try them out. Thank you :o: Link to comment Share on other sites More sharing options...
ls1_alex Posted May 25, 2005 Author Share Posted May 25, 2005 Allright, it seems for me that pressing on the pump resolves the issue as well. I tried swapping the water hoses quite a few times through the day and the ticking never went away. I am using a mobile athlon going at 2500mhz - my temps are 43 idle and playing everquest 2 56-58 - room temp is 80F. I expect it to get worse as the summer gets warmer. These temps were never really acceptable to me but I noticed that if I put a blower fan pointing on the heatsink the temps went down considerably. I've been using it that way for a while. With the blower the temps are 38idle 46 playing EQ2. I bought this unit from ZipZoomFly and it was missing most of the parts necessary for assembly so I am wondering if perhaps I received someones returned unit... The parts were eventually sent to me after a few phone calls to ZZZ. Btw I did not notice any difference with the system being on the floor or above the waterblock. Please advise on what my next step should be. Link to comment Share on other sites More sharing options...
KaptCrunch Posted May 26, 2005 Share Posted May 26, 2005 looks to me you need some air management to work with your case, by chance do u use cathoids? or add a top blow hole in case Link to comment Share on other sites More sharing options...
ls1_alex Posted May 26, 2005 Author Share Posted May 26, 2005 Although this case was chosen specifically for air management the system now runs with the case fully open. The temps I reported are with the case open. It has been for quite some time now. Today it cooled down a bit and the noises went away. But if I put my blowdryer on a slow speed and let the temps get to 36c on the HC the noises come back big time. :(: Link to comment Share on other sites More sharing options...
stev Posted May 26, 2005 Share Posted May 26, 2005 ls1_alex, Putting an extra heat load on the cold-block to raise the temps actually increased the noises? OK, the question I have, since the ZZF issues is, did the HC system come with a FULL bottle of coolant? Also, did you fill the unit and top it off with "distilled" water? The coolant mixture is critical. Corrosion can settle in the system if there is an improper balance to the 33% Propylene glycol (PG) to 66% distilled water that is needed. Remember, the cold-block in the HC uses micro-channels. Any internal corrosion can clog them up. With the pump making noise, it sounds like the PG coolant balance is off too. The PG coolant also acts as a pump lubricant. Link to comment Share on other sites More sharing options...
ls1_alex Posted May 26, 2005 Author Share Posted May 26, 2005 Hi Stev, actually putting the extra heat on the water tank in the HC system and heating up the water causes the noises to start. I used a hair dryer for that. Yes the system came with a full green bottle of coolant and I did top it off with distilled water :): If you think I need to add more coolant to it I can try that. The pump is dead quiet though at 35c and below.. :roll: Link to comment Share on other sites More sharing options...

The pump is dead quiet though at 35c and below.. :roll: ls1_alex, OK, your coolant mixture should be just fine. Topping the reservoir to the first few threads inside the reservoir is the best level to keep. Another question, when the heat is applied to the reservoir via the hair dryer, can you look inside the reservoir and see any white foaming action going on? If this was a return product back to ZZF, the previous person MAY have used regular tap water or a non-friendly coolant. Why do I say this? The unit did arrive to you with a full bottle of coolant. If this is the case, you could RMA to ZZF per their terms, or try flushing the HC with "Distilled Vinager" and then flush back in 33% PG with 66% distilled water. This is only my best guess. It may OR may not correct itself. Keep us posted! I'll be away at an offsite training class for a week shortly. Stev Link to comment Share on other sites More sharing options...
ls1_alex Posted June 8, 2005 Author Share Posted June 8, 2005 Well it seems that in order to quiet this system I have to add more coolant to the HC system which is way above 33% and kills the performance of this system. Taking fluid out of the system and adding more distilled water I noticed the temps were better but the ticking started at a lower 31-32C. As usual applying pressure to the pump resolves the issue. This can't happening to all HC systems out there, is it possible I just have a lousy noisy pump? :confused: Btw swapping the hoses did absolutelly nothing.

7SinsLust Posted June 8, 2005 Share Posted June 8, 2005 I never got a reply from COOL GUY either, it was a good thing that RAM GUY replied, at least I had the forums to relate my problems to. Link to comment Share on other sites More sharing options...
Zappattazz Posted June 10, 2005 Share Posted June 10, 2005 How does one determine if the existing fluid in the HC is the correct 33%PG/66% DW? In my HC200, I started with the full coolant bottle provided with DW topped to the threads. Even with various tube lengths possible, does this method create the proper mixture values? Once a month, I check the "fluid" level and top off to the threads with DW if needed -- wouldn't this "thin" the soup over time? How do I know when to add additional PG to get back to optimum? An automotive antifreeze bulb tester? :eek: Link to comment Share on other sites More sharing options...
SpDFrek Posted June 10, 2005 Share Posted June 10, 2005 Zappattazz- An automotive tester would be the only way to tell exactly what your mixture was. If you continually add a small amount of water you will eventually have a low mixture %. At that point flushing the system and starting over with a full bottle of coolant will again give you the right mixture amount. Link to comment Share on other sites More sharing options...

Hopefully everyone has kept their PG bottle that came with the HC. :roll: It will help with the measuring and mixing of the coolant. If you tossed out the bottle, :eek: then go to the kitchen, swipe the 1-cup measuring cup from the wife, and for every one cup of PG coolant into a one gallon jug, add two cups of distilled water. :) Just rinse and place the measuring cup into the dishwasher when done. :sunglasse PG coolant is food friendly safe. PG is found in salad dressings, gummy bears and other food products as a sweetner. Stev Link to comment Share on other sites More sharing options...
ls1_alex Posted June 15, 2005 Author Share Posted June 15, 2005 Hey guys remember me? :p: Should I RMA my unit and hope to get a quieter pump or what? Other then choking the unit with coolant and killing the performance I don't see any other options of quieting this thing down. :confused: Link to comment Share on other sites More sharing options...
Yellowbeard Posted June 15, 2005 Share Posted June 15, 2005 It sounds like RMA time. I'd contact ZZF and provide them with a link to this thread to demonstrate that you have been thorough and tried to resolve the issue. Since you have having problems with an incomplete kit, they "should" RMA with no hassle. If they don't help you out, post here again. Good luck, Mike.
