For every one who ragged on Koolance - Load = CPU 39-40 GPU's 51 + build pics 56k= :(

[1031.nu]

Every one talks alot about flow being the most important thing in the world. Every one says without without that highflow pump your system will be the elsucko. From what Iv read koolance is def. not in the high flow category at all, so just cooling a cpu down would be a work out for it. Now adding 2 6800 ultras must really do some damage.

Some of you may remember, I had slightly damaged my home made block last month and needed to get my system up and running, so i was able to get an old koolance unit from a buddy of mine. This is the exos, with the 3 80mm fans. Any way, thinking the little guy woudnt be enough for a cpu, and 2 gpus I decided to play with some resources from my last build that failed.

Screenshots of the first tests below, keep in mind this CPU is old and beat up a little bit.

I left one side unpainted, I only wanted to put a light coating of paint over the visible side to have a nice clean look. I didn't want to hurt the thermal transfering abilitings by covering the fins with paint, which ment the heat would have to be disapated through another service.

1/2 Gallon of Zerex and Destilled water ... I ended up doing around a 50/50 mix. I may add more water later.

During testing it was about 78-79

And the links below are the screen shots I took for the first tests on the system. The first shows only a load on the cpu, the second shows a load on both the cpu and the GPU's.

Screen Shot 1 = 1 hour load temps - CPU (http://www.1081ds.com/pics/koolance/ss1.jpg)

Screen Shot 2 = CPU + GPU Load temps (http://www.1081ds.com/pics/koolance/ss2.jpg)

Thats rite now .. I'll be ocing the video most likely soon, and seeing what else I can do with the CPU.

So just a note to every one ... Koolance isnt that bad, dont need to spend alot of money to get decent temps ... No its not perfect .. but it'll work till I get a pump and res and some other stuff and build a completly internal system.

What you measuring temps from.

[Holst]

Nice one :)

The najor problem ive had with coolance is there rads, and you seem to have solved that rather nicely :)

As long as the waterblock is designed for lower flow you can still get fairly good temps.

It would be an interesting experiment to put a bigger pump in your system, just too see if your temps drop much .. I suspect that they wont. But it would be nice to try it.

nice clean install, good job :D

[afireinside]

Crank up the clocks and volts and say its still good. Koolance sucks. Big time. End of discussion.

I'm using the same block with mcp655...you'd be right. There's actually a point where the water will move too fast through the block to cool it when the pump is cranked, and temps rise about 3c...not enough turbulence for the high flow i guess.

Puhleeese dont start with this rubbish. If temps rise it is due to pump heat, not because of too much flow.

Theres 2 links up there with screenshots from my desktop, they show the speed , volts, and temps through mbm5.

Yea my main issues is that its alu, and my other one is copper. Which is why i'm using such a heavy concentration of zerex, to help prolong that corrosion every one speaks about.

I plan on getting a new pump and res sooner or later, and maybe a new water block and move some stuff around but I'm not sure what to do yet. I plan on keeping it all in my tiny old mid tower case. Its white with black drives ... ohhh sooo trendy and I don't want to get a bigger case. So I'll use this till theres nothing left. Rite now I have a 1/2 inch between my HD and the second rad, theres just no more room :)

Its running fine for me. I plan on uping the clocks soon enough. Im only at 2574 rite now so we'll see. I would love to try out a new chip but no money. So I'll have to see how far I can get this old NewCastle to go.

:D never thought of that. :rolleyes: so i could be getting lower temps then, but the pump is preventing it? :eek:

so then why have a higherflow pump? :stick:

For blocks like the storm I would imagine.

[cadaveca]

Yeah..that was kinda my point from the start. Koolance have done a decent job in choosing a pump to match thier block. Could be better, but as you say no too bad.

But you are using a second rad, apart form the exos, no?

Yea i am using a second rad. My point was to show even with what I would think would be a pretty damn low flow rate, with 5 things in the loop (2 rads, 2 gpus, and a cpu) my temps arent that bad. Flow rate isn't everything, and koolance isnt the devil.

[Cathar]

Pish-Posh. Storm is designed for Eheim 1046 pumps and higher.

SystemCooling put the newer Koolance blocks about dead even with the Swiftech MCW6002 (click for reference (http://www.systemcooling.com/images/reviews/LiquidCooling/CoolTechnica_AquaXtreme/image31big.gif) - also includes proof that the Storm canes the Koolance block with ANY pumping power)

Using a big radiator, and a decent pump, is it any wonder that the setup performs fine?

I wasn't sure what the storm block was designed around but you learn something everyday.

The koolance 300-v10 uses 3/8 hoses, I'm still using the tiny 1/4 hoses, again would love to upgrade but its all money.

As far as the pump, its nothing special in my setup just the koolance. People rag on koolance day in and out, just wanted to give koolance a little push, and help show there not the worse out there, especially with a little work, even with the low flow. Im using an Exos1 im not sure if they upgraded the flow for the Exos2.

[Craash]

Well answered my question to the post i just left. Have you tried a parallel setup? Ive read it helps the flowrate and from personal experiance with the exos in series system it might help some. But very intreasting post.

[Cathar]

You won't hear me ragging on the Koolance setups.

My personal opinion is that they are middle-of-the-road mass-market focused water-cooling setups that do an okay job of servicing the "I want to water-cool but want a kit" crowd.

Of all the water-kits out there, you can certainly do a lot worse.

Koolance are fine, just not top-end. Sometimes people get a little snobby about it at various forums that like to focus on top-end performance, that's all. No point in stirring people up though. It's like a midget with steaks strapped to him walking into a pack of ravenously hungry wolves and attempting to pursuade them that he should not be eaten too.

[MaxxxRacer]

As holst and a few others, the koolance blocks are very well optimized for low flow (well you would be hardpressed to get high flow in them) and thus do no need a large pump to be used correctly.

again as pointed out, koolance provides horrible radiators in their setups which cause overly high water temps, cuasing poor performance.

This is the only setup I have tried. I don't want to start splitting stuff to run a parallel system. If some one knows how to hook one up easily, I may give it a try, but not just yet. I'm not concerned about flow rate, if I was I woudn't have the GPU blocks there. Just tring to see if I can take the focus off of that.

Im not defending that they are amazing buys and every one should go pick one up. If I hadnt gotten this second hand, its a good chance I woudnt of tried it at all. Now that I have tried it, I know that with just a little effort you can make what people consider a bad system to a better system, and its some what DIY. Some people dont have all the tools to do a good DIY. Like me for example, I coudnt find any nylon bolts long enough to go through the rad, so I had to resort to using zipties. It gets the job done, but Id rather something a bit neater.

Quick question, does UV additives hinder performance in any way, or do they allow for extra groth or corrosion possibilities ?

[MaxxxRacer]

UV dye shouldnt have an effect on biological growth in the system nor promote corrosion to the best of my knowledge.. havnt done any test, but it seems unlikely such a small amount of fluid could make much of a difference.

the amount is so small it really wont effect performance at all.. granted if u dump in a ton of the stuff it might have a negative effect.. but for the amoutns we would use.. no harm..
