looking for ideas to improve my water system performance

[[]i9]

hey all. After getting my system back up after my recent hose change (which I can recommend the stuff) I find that my overall temps are not as good as I would hope. I hadnt been running my vid card in my loop for since I got my new Geforce 6600 GT, because I couldnt find a waterblock to fit it.
Since that has been resolved, I would like to get ideas on what you guys think are my weak spots, and weak components.

So here is a list of components:

CPU Block- Dtek White Water
Chipset- Danger Den Maze 4
Video card- Polar Flo TT
Pump- Swiftech MCP600 160 GPH
Radiator- a dual 120mm size heatercore no brandname
all of the system is 1/2 ID
I use a T-Line for filling


So right now my temps are (this is according to NVMonitor)
CPU: 105 F 41C
System: 89F 32 C
GPU: 145 F 63c

under load Ill get around here:
CPU: 110F
System: 93F
GPU: 185F


And this is my hose routing
Pump> CPU > vid card and chipset block > radiator > pump

any thoughts?

thanks

Are all these temps at stock speeds? Also I'd try pump>rad>CPU>chipset>VC>pump.

woops. I should have mentioned that. GPU is stock, FSB is at 228, so the cpu is o/ced to 2052

did you see a change between putting the rad between the pump and cpu and putting before the pump? If so how much?

1) pump is too weak. you're going through a dual heatercore with 3 blocks and you're only using a MCP600. i'd suggest at least a D5, preferably an iwaki.
2) that CPU block isn't the best. DangerDen and Swiftech hold the best of the best in CPU blocks (under Little River of course ^o^)
3) order... try going pump -> rad -> CPU -> GPU -> chipset -> pump

and please post temps in celsius for us. i'm not really familiar with fahrenheit since i never use it in regards to system temps and most of us usually use celsius.

you can add another MCP600 to the loop, these pumps work well in series, it'll give you a nice boost in performance. The pump before the rad should give you a small boost but nothing too significant because your pump doesnt put out a lot of heat for the rad to remove. Take out the chipset block it is completely useless in your system and just adds heat and reduces flow which you lack.

I posted celsius or ya

where in the loop do you put a second pump?

I'd skip the 2nd pump idea, it'll just take up too much room. I'd just upgrade the pump. The Hydor L30 is a pretty decent pump and its cheap.

I use a L30, RBX, Maze4 GPU and a BIX rad with 1 120mm fan. These are my unloaded temps with a 3400+ and 800xl.

[moonlightcheese]

i dunno... for 3 water blocks... i'd suggest the Iwaki. your flow is already suffering a lot.

Best performance to decrease ur temps:
RUN ur air condition!
I am so sick of paying 200 bucks every month paying gas and electricity,
which forced me to decide get phase change for both my comps

what temps? I cant see anything.




Okay, so heres what Im thinking so far. If I take the NB cooler out of the loop, that drops my head about 18 inches. (sorry metric guys)

I cant really change out the GPU cooler since its the only one that fits this card. And Id rather not spend the $75 on a cpu block and not improve my gpu temps at all. So a new pump sounds like the best option.



Is the Iwaka a 12v pump? And aside from that one, what pump would give the best performance? I had read somewhere that the Whtewater did better with a low-flow anyway.

he posted his temps in a thumbnail. click the attached pic.

taking out the NB is a good idea, then you don't really need the iwaki and a D5 would work just fine. the iwaki is an AC pump.

[[]i9]

there is no attached thumbnail that I can see. My browsers I guess. Oh well.

Is the D5 a DD pump?

D5 is from DangerDen, Swiftech MCP655 is the same pump. Laing makes both of them. either one is fine.

There it is. Want to get temps down? Drop room temp by 5C...CPU temps drop by 5C...it's a 1:1 with watercooling...

not in my house. If I could drop my room temps by that much, it would make little difference to my sys temps.

I'm pretty sure the laws of physics aren't any different at your house than they are at mine. I'm telling you...the radiator works on a simple deltaT principle...drop inlet air temps by 5C and outlet temps go down by 5C...and water temps go down by 5C and then CPU temps go down by 5C. Now, there is a little more math to it in some places but nothing you would ever notice. Point is, just get the room temperature down.

it's true. that's one of the advantages of water cooling. closer to ambience than air cooling. the cooler the ambience, the cooler the temps. i keep my place coooold ^_^. i like it cold. just like my compy ^o^

hehe. my house doesnt follow standard laws of physics.

Doesnt matter, that would be the most inneficient way of dropping 5 degrees anyway. I want my computer to drop 5, not my house.

Pumps are much cheaper than electricity.

these guys don't lie man!

reducing your ambiant temp has a HUGE implication for water cooled setups, I know, as my room temp changes 10-15 degree F in a given day. In the morning my cpu is idle at 26c, in 6 hours it's up to 34c idle and still rising.

It's much easier to drop your temps by droping the room temps.

do you guys honestly think that I am so stupid as to not understand the simple concept of room cooler= computer cooler?

Im telling you now, it is not a worthwhile option for me. If you want to pay my electric bill fine, Ill crank the AC.

Good god

I think what we are trying to tell you is that you could have God's very own WC setup and it won't matter if your ambiant temps are sky high. Thats all. Nobody is trying to make you feel dumb or anything.

5 posts is excessive. I dismissed the idea after the first post.

[MaxxxRacer]

FGC, it pretty much works like that as you say, but I've noticed that its not perfect. it is fairly linear in a small change in temp but if u change 30C in temps the linearity goes out the window. but im sure u know that!

[moonlightcheese]

hey []i9... sell me that chipset block XD

hey []i9... sell me that chipset block XD

as soon as my HSF comes in from Newegg, its yours. I have some other water stuff too, but I cant post that here yet. If anyone is interested, I guess its okay to PM me.

hope I dont get banned for that.
