Need advice on case kooling (koolance)

[gumboglue]

Hi !

I need some advice on my case-cooling.
I got this baby http://www.koolance.com/products/ccs-a01/# (click more pictures)
And my problem is that i get system temperatures up to 37ºC.
System temperature is the case-temperature, right ?
My waterblock-probe reports max cpu-temperature to 38ºC but my socket-probe reports CPU-temp as high as 47ºC.
According to Koolance this is no reason for concern and its because of no air-circulation around the socket.
My idle-temps are usually 27-34 (CPU and case) and room-temperatures varies around 18-26ºC.

OK, this is probably my own fault because i want everything as silent as possible.

The three fans on top cooling the radiator are Papst 19cfm's (12dB) configured to blow cool air in to the case at the radiator.
At the back i have two more 19cfm's to exchaust air and i've moded my dualfan PSU to use two 19cfm's to exchaust (full speed).
I've used sound-deadening mats in the pc and the only other air-intake is the hole infront of the water-container.

What do i do to get down system temperature ?

Do i move the water-container and install another 19cfm as intake ?

Do i turn the front top fan to exhaust air from the radiator where the hot water enters (thus making it possible for the other fans to suck the hot air in on the radiator again, was standard config) ?

Do i make a top-hole for exchaust with another 19cfm behind the radiator-cooling?

I'm considering replacing the 19cfm's in my PSU with 26cfm's(19dB) since it gets a little hot. I won't make a blowhole in the side-door because of noise-issues.

Any advice ?

38C is good enough..
your mobo reads a higher temp cause no air circulation..

but if you want lower temps you can get a big resovior

Ive got one of those koolance systems myself with CPU, HD, MB, and GPU watercooling. First What are you cooling? Are you just watercooling the CPU? or are ya cooling other things? Second, Where are you geting these temp's from? Are these the temps that your koolance thermal probe is reading that's attached to your waterblock or are these temps of a probe you put in? Right now with Ambent room temps of around 22C My koolance probe reads 31C LOAD and my CpuNurse Thermal probe (located right next the the cpu core) reads 35C LOAD. Ive got CPU, HD, MB, & GPU all watercooled with the system too. And ive also got NO rear or front case fans. The only fans that are in the case are the 3 on the radiator, and the 1 on the PSU. IS your CPU or any component overclocked? If so then your getting good temps?

[raventy]

ah crap you are overclocked.. and a pretty nice OC I might add.. 190 FSB damn.. hehe .. thats no longer a 2000+ cpu ya got thier.. more like a 2200+ ;) But yea those are good temps for your oced system.

[kaltag]

your temps are fin IMO. I don't want to bash on it but those koolance systems aren't that great. they've only got 1/4 inch tubing, a low volume pump, and plastic top waterblock. i'd say your getting surprisingly good temps with that setup :)

Thank's for the replies. Well, i was hoping to get case-temperatures no more than 7-8ºC over room-temperature.
I think i'll try adding an intake and replasc the PSU-fans with some 26cfm's. If that doesn't do the trick i'll try to turn one of my radiator fans to exhaust.

[gumboglue]

Raverty ! It's the front radiator fan that is set to exhaust on the standard config right ? I think the water enters the radiator in the front... Is the air that it exhausts hot ?

[Wicked Klown]

The first two fans are intake and the last is exhaust.

[raventy]

yes, the fan at the front of the case on the radiator is exaust while the others are intake. The air that comes out for me is "warm".. not hot not cold.... my psu on the other hand... is pullin out hot air.. haha.. damn 400watt untec psu... I think ill be getting a better one sometime some, like an Eternmax. Oh and I think the water flow goes to the back of the radiator (where the 2 intake fans are) then goes to the front... If ya want I can check when im home latter.. hehe right now im at school durring a free period.

[gumboglue]

Yupp ! seems like there has been different radiator fan-config's.
The one that Klownin79 mentions is the old one and the ones we have is used with the 601 system.

Yes please, it would be nice to be sure which way the water flows trough the radiator.

Would you say that the air from the radiator exhaust-fan is warmer than the case temperature ? approx. how much ?

I had an enermax 330w and didn't like it. The molex plugs started to make bad contact after connecting them 7-8 times and the one i had was a silent type but the fans was to noisy (not the adjustable type). I'm very happy with my Topower 420w and think it's a better PSU. I opened them both and the Topower had larger "heatsinks" and had the "quality look". But enermax is still one of the better PSU's around (no flaming please ).

Ps! Have you always used the 200w.waterblock ? If not, how much cooler did the CPU get from the 100w block ?

btw. I'm only cooling the CPU and the GPU

Alright after looking at my case, My tubing goes from left res pump nozllele, to HD, to GPU, to MB, to CPU, then to the Rear Radiator nozzle. I belive the water flows it that order too. So it hits the back of the radiator first then goes to the front. Ive always been using my 200Watt waterblock so I wouldnt know. And for those who like flamming the koolance system, I think they are wrong. I mean after seeing the results on some of those home-made ones with the maze and aquaview waterblocks.. my temp beat them, and ive got GPU, HD, MB, and CPU watercooling. I think the koolance system is designed to keep everything at one steady temp no matter how many things you attach. (Well their is some limit but you can attach quiet a bit). I think the air coming out of the radiator exaust is a little bit warmer than case ambient, but is not that much. The diffrence doesnt seem that noticable. Yea when I get more money ill probely buy a new, better, PSU.. ill have to look up some info about them. I need a quiet and pwoerful cpu.

Thanks !
Think my water is pumped up to the front of the radiator and exits at the back. That would make sense too since the first fan is exhaust and thereby exhaust the air from the hottest part of the radiator insteed of blowing it into the case. The last fans wil then cool the last part of the radiator with cool air before the water returns to the cpu, mb, etc.before getting sucked back to the pumps.

I turned all the fans on top to blow outside air in on the radiator for maximum CPU-cooling and i also thought that it was kinda noisy with the air exhausting in front. Im sitting pretty close to the pc and that was before i replaced the fans with quiter ones.
My concern now is that the radiator is heated up by the hot air in the case.... Allthough i got three intake and three exhaust (+1 in series in PSU) it seems the hot air isn't getting out, 38ºC.....

Seems koolance has used many different -fan/radiator configs.
My manual had an "addon" saying my radiator was turned for easier access to the drain-screw and i'v seen pictures on the web with two exhaust and one intake-fan (first model?).

[raventy]

yea I think the one where it has 2 exhausts and 1 intake was the earlier model. Oh and what fans did you use to replace the koolance supplied ones? I would assume their still 80mm, and are they quiet?.. and how quiet might that be.. like virtualy quiet or barely diffrent than b4? And do the ones u put in still cool the system as well?.. like is their cfm rate alot lower ect...ect.. Oh and now that I think about it... im not realy 100% sure which was the actualy pump is pumping the water... I kno the tube does go from my cpu cooler to the back of the radiator, but today when I had an air bubble in my waterblock it seemed to be being pushed the other way.. hmmm.

I use 3xPapst 8412NGL 80mm 19CFM at 12dB. Originals are 28cfm's probably at 28-32dB(max).
The papst doesnt use ballbearings and are therefore quiter than other low-cfm fans.
http://195.70.174.166/rubweb/prodpages/8412n2gl/papst8000.pdf

At min mode (level2 beneth 35ºC) they run at aprox 80% speed where the others ran at 50%? At 38ºC they run at 90-95 %speed. They run faster than ballbearing fans on that controller-board because they got less impedance / resistance / Ohm's / whatever.
I first tried with Papst 26.5CFM's at 19dB , but then there wasn't much lower noise at normal use, only at full speed, and the temp.readout was the same as with the 19CFM's.

I guess by using weaker fans i'm not able to cool down the same amount of heat anymore, but it's still more than enough for me and the controllerboard never uses full-speed mode.
