Water Cooling with high temps need help!!

[Warlord2]

I just got my last part for my water cooling setup today so I put everything together. After I got everything together I purged the water for air and started it up and seems to be holding at 46c idle

that is worse thim my fop38!!!

Im using DD maze2 and the DD cube and a good size resivor for the 140gph pump
I have 85cfm of air sucking through the DD cube "120mm radio shack fan"
so Im thinking it is either the GPH that Im lacking or the cfm
I live in a very hot climate "bakersfield" but like I said my fop38 was doing 41c hella loud though
what do you guy recommend I do????
Im a little scared about tieting the maze2 screws any more sense I dont want to crush my 1.2ghz cpu
the spring that came with the maze2 are closed to 3/8" on all sides at the moment "from block to screw"
my case is also open if anyone wanted to know that...
right now my room temp is around 85f
note that the water seems a little hot when I touch the plasic
Im also using around 90% water 10% anifreeze

where is your resivor in relation to the computer, in other words how much tubing is the pump pushing the water through?

what order is the setup running in?
pump>>>maze>>>radiator>>>> pump is what ive seen the most also seems the most logical to me..

now when you say the water seems a little hot when you touch the plastic are you refering to the tubing or the res?...if the water isnt being cooled enough that maybe your problem..how large is the resivor? and what is the temp of the water in the resivor?

I think you may be right about the GPH but if the water is warm, your room is 85f, that could be your problem as well...rememberthe higer up the water gets pumped the slower it goes.

[Warlord2]

Im not using much tubing at all just enough for me to get the water where I want it maybe 2 1/2' of 3/8

Im talking about the tubing when I say its hot to the touch
I have no idea how hot the water is getting sense I have not temp probe now

Im also running pump->maze->radiator->resavor

the resavor it about 11" hight and 6" diametor

I think Im going to get a new pump like a 300gph
the pump Im using now is about 20 years old so it most likely pumping around 100gph instead of 140gph

[Tacoman667]

Look at my sig. Those are the temps I get with my closed case, DD cube inside the case, a YS-Tech 131cfm 120mm fan sucking the air outta the cube, adn a Eheim 1250 Hobby Pump submerged pumping thru about 3 feet of tubing from DD and doing so at 315gph. You should get a better pump that pushes more thru the system because it looks to me that your water is absorbing the heat too fast. Plus, heard of an air conditioner? My room temp stays around 70-75F and I get these temps all the time. Try these things.

[Obsydion]

I echo that belief as well. You seem to be lacking in pump capacity. I have your setup which works fine. With the cube the pump will have to be at least 300GPH.

[Colin]

I'm about 60 miles North of you and understand your ambient temps. Your pump could be lacking. I have found the Danner 700 to be optimum with a Cooling Cube and Maze 2. You could also run distilled water and Water Wetter. It transfers heat better than antifreeze. But if your tubing is quite warm to the touch, the heat is getting into the coolant, there is just not enough flow to take advantage of the Maze 2 and Cubes unique properties.

BTW, I should be at the computer show in Bakersfield on June 16. Going to skip the Fresno show this weekend.

[Warlord2]

thank you soo much you guys Im going to try to get a new pump tomarrow and should I get a new fan as well?


how load is your fan that is sucking 131 cmf

well anything is better thin a fop 38 but how many degrees will I loose with a 131cmf fan?

[Warlord2]

Im using distilled water right now

maybe I will try putting more water in

[Warlord2]

boy I was pricing some 300gph pump and they cost alot!!

does anyone know of a good pump that is around $20-30?

The danners I think. But I saw the prices myself, and what turned me onto the Eheim is that many here use it and say the quality is oustanding. So I got one and I have absolutely NO complaints on them. I can pump out 315gph up to 5 feet of tubing. Not many can beat that. The magdrive's and rio's seem to have a magnetic effect on ppl's components so I would stay away from them. Just a few suggestions. I feel the 70 bucks I paid for my 1250 Eheim is well worth the money. I will not be needing to change my pump anytime soon. Hehe.

[Colin]

The Danner 700 is about $55 from one of the online pet supply vendors.

[Warlord2]

does anyone know how big the Danner pumps are sense I have to fit it in a 6" diamitor resavor?

[Spewn]

Is the tubing coming off the radiator hot? Or just the tubing coming off the waterblock. If the tubing coming off the radiator is hot, then that means your pump is doing just fine, but your radiator isn't pulling it's weight. If not, then it's the other way around :)

[Colin]

About 5 * 4 * 4" without fittings. I would run it inline though. If you are running a submerged pump your plumbing order should be pump/reservoir, radiator, block. This way the radiator can take the heat the pump adds to the water out before it gets to your block.

[Timmæy]

If you water is running hot like yours is then try to put the rad before the block, also try getting either more cfm over the rad or try running a bigger rad. I am running at rio600,moded to sit outside the res,the a 1.5 gal res,the the water goes to the rad,a heater core i pulled from a 72 toyota pickup, then down to the block. I idle at ~24ºC with a rad inlet temp of 26ºC.

I did a few tests by putting the system under a load with the rad fan off until the rad temp gets to about 110ºF then i turn on the fan to see if the rad/fan is working properly, I drop the temp from 110 to about 88ºF in under 5min. so after you get our new pump in tru a little test like that to see if you rad/fan is adequite.

just my two cents

Having run this setup for several months with a 700 GPH inline pump, I know the radiator is up to the task. 84 CFM from a Radio Shack fan should work although the temps would drop about 4C with Two 100 CFM pushing and pullling the air through the radiator. The problem seems to be water flow. Note my temps dropped 3C when I switched from a Rio 600 to the Danner 700.

[Warlord2]

Colin Im glad that you told me what I would get with 2 100cmf fans

I think Im going to stick to one right now and see what I get

I might also try going resavor->radiator->maze2->resavor

see how much that will help

I alost tryed reseating the maze however that didnt get any better

[Colin]

Just incase you decide to get a new pump, Petsmart has a $10 off $30.

BTW, I run two 131 CFM YS Tech fans on my Cube but with the LM317 voltage regulator they probably max out at about 115 CFM.

thank for the info solin

[Warlord2]

I got a 350 gph water pump and am idling at 41c instead of 44c with the 140gph

my rotation is also changed resavor,radiator,maze,resavor

I think we all know now that I need some better fans for the dd cube

can measure how far there distance is between the block and the screw for the maze2?
and has anyone tryed lapping the maze2 and got better results?

[Warlord2]

but hey the water is alot cooler with the new pump!!!

[surlyjoe]

if you put the rad before the block and afetr the pump it will shed the heat from the pump also , before it gets to the CPU

You may need to tighten the nuts on your block. It may not be as secure as it should be to effectively cool off the CPU.

[Colin]

Glad your temps dropped. Is the tubing cooler to the touch?

Your block is lapped by Danger Den with 600 grit. You my gain a bit by lapping it further and doing the final lap with Artic Silver as the lube but I would get the antifreeze out of the coolant first.

One more thing. One fan on the Cube should be drawing the air through it, not pushing.

[Warlord2]

yes the tubing to cooler to the touch

I am using artic silver right

my fan is sucking the air into the case through the dd cube

I think I may buy 2 100 cmf fans for the dd cube and have the one Im using now suck air out of the case

I would realy like my temps to be below 40c so I can do some o/c easyer

[Warlord2]

now that was interesting I just ran prime95 for 1 1/2 hours and my temps where 41c idle 42c load


Im wondering if my radiator is working good and room temp is just holding it back=/

[LimeyGreg]

I would try to see what the temps of your coolant are entering the rad and leaving the rad and how close the exit temp is to the ambient temp. Is your rad external to the case? If not then you are trying to cool it with warm air from your case.

If you feel adventurous, then remove the whole cooling system and set it up by the sink, take some tube from the block to a bucket to collect water (at same level as rad & res), connect another tube to the inlet of the reservoir and put the other end in a sink/bucket of water. Now fire up the pump and see how much water it pumps in a given time, it should give you a good approximation of how good the flow rate is.

Finally, I would look at your CPU and make sure that it is flat, when you pull the maze is the impression of your CPU die complete or is it partial? It may have a foreign body between them or they are not mating up properly - I doubt more pressure will solve your problem.

[Warlord2]

my radiator is taking sucking in cool air from the outside

as for the water temps I know the water has not reached 100f yet but I dont know what the exact temps are for I dont have a temp gage that is accuret

the pump was $50 and is 350 gph so I dont think that is the problem

Im going to try lapping and putting silacon between the fan and the DD cube
to see if i cant get any more air through it

[Tacoman667]

I only have my one 131cfm 120mm fan sucking air outta my radiator. And it's only held on with plastic zipstrips. Remember that you are only using a 50 something cfm fan on it right now. Pull more air through it and I bet you will see more cooling of the water. Hell, my radiator just sits in front of my front intake fan<80mm> and has the 131cfm sucking that air and some case air through the radiator and I still get pretty close to ambient temps on my CPU.

[Colin]

The Radio Shack fans are conservatively rated at 85 CFM.

[Warlord2]

yes I have a 85cmf on right now

going to have to order for anything bigger

[surlyjoe]

Those Radio shack 120mm fans are junk, I have had terrible luck with those things , out of 4 , only 1 lasted more than 90 days, and the warranty on them does not apply to the replacement. so if the one they replace they bad one with goes out , your screwed

[Warlord2]

I feel very happy now knowing that=/

[Thelemac]

I would definately say that your ambient is holding you back. You're getting a delta of ~11C...not too bad, that's about what I get. Running an ambient of about 30C is bad.

What kind of case cooling do you have?

[Colin]

I have four of the Radio Shack fans in another box. No trouble at all. I prefer the 131 CFM YS Techs for umph but it's hard to stay away from Panaflows when MJPA sells them for $6.99. I bought ten of the 86 CFM ones from them for a future project.

[Warlord2]

my case cooling sucks but right now I have a 15" house fans blowing right into the case but I will need better cooling if I close the case to go to a lan
