watercooling n00b needs some assistance

ok i just picked up an aquarius II watercooling kit from a member here as my first venture into watercooling...i just got finished setting it up...its cooling(i use that term loosely at this point 😉 ) a barton mobile@1.45v@1.8ghz on a nf7-s v2 right now and my temps are quickly climbing up to 55C! yikes

wondering if someone might be able to give me an idea of what to look at first...its set up as follows:

pump output-->cpu block inlet-->cpu block outlet-->radiator inlet-->radiator outlet-->resevior

the pump is submerged in the resv...it appears to be pumping...the pump is running...but when i start up the system it takes about 3-4 minutes for the cpu temp to go from 34C to 55C...thats where i shut it down...any ideas? is my loop set up wrong? maybe the cpu block isnt making proper contact?

i've been overclocking for some time, but this is my first watercooling experience...i'm not off to a good start, lol

any help would be much appreciated!

thx in advance
 
ok i figured out my first problem...air in the lines...doh!

now i have some questions about how to get the best temps out of this setup...should the fan pull air through the radiator? or should it blow into it? i am going to lap my waterblock tomorrow... its not in very good shape at all...gouges and imperfections galore...i cant even see a reflection of anything in it when i try...think that will drop the temps considerably?

i'm running at 41C right now idling at 1.7v@2.2ghz...this is performing about like my old air setup(thermalright slk700)...i didnt expect a lot better performance out of a kit this small...but i expected it to be better than air at least...anything i should change with my loop?

any suggestions would be welcome...i'm about to start playing with my clip holding the cpu block down...maybe if i can get a bit better contact i can get lower temps...
 
ok i got the temps down some more...i'm at 46C under full load right now at 1.75v

the water block wasnt down tight enough...i didnt realize just how tightly you had to clamp it down...i was afraid i was gonna crush my poor little athlon xp's core, lol

tomorrow i get to lap the block...it looks awful...hopefully that will net me a couple more degrees 🙂

guess noone is planning on giving me any advice 🙁 ...o well, i'm figuring it out on my own anyway.....

any suggestions or ideas are welcome!
 
In your case I'd suggest plumbing your rad just before your blocks. The fact that you're using a submerged pump means that you're imparting pump-heated coolant to the start of your loop. This configuration will also supply the highest Delta-T to your rad, which makes it perform well in terms of cooling. Also, and I know this is going to be a downer, but your selected kit doesn't rank towards the top in terms of performance.

thanks for the advice...i'll try that...i know its not a really good performer...but i got a pretty good deal on it, and its pretty quiet...besides...its a good way for me to get my feet wet(heh, no pun intended) with watercooling
 
and why has my case temp gone up about 2C after installing this kit?

i figured it was gonna go down...since the hsf isnt there radiating heat into my case anymore...
 
OK, I have a Big Water that performs quite good. Your case temps are up probably becouse the radiator is making more obstruction than your previous config. I guess everything is inside the case. Don't bother, that makes almost no difference. I have my WC set-up like you and performance is pretty good for the price. Is your radiator 120mm? Lap de WB, mine came with mirror finish. Also let you thermal paste take it's time to perform as it should 😉

well...the radiator is mounted in my case side panel...where the fan for my cpu duct used to be...none of the other case fans have changed...its an 80mm rad...and yeah i need to lap the waterblock..its looks awful right now...a better radiator will probably be the first upgrade i do...i like your setup btw...it looks pretty good

how big of a difference would a better pump make? i'm thinking a good dual 120mm radiator will help more than anything at this point

EDIT: i also changed the loop to: pump>rad>cpu>resv that dropped my idle temps about 1C...about to see how it does under load
 
Between case temp and CPU temp there are 6 to 8C difference. That's the performance of the cooling.
Also the pump is not a big factor. Mine does 120L/h, with the diameter of my tubes it goes at a speed of 1,7m/s, which means it does go throw the whole circuit in less than one second. I think yours is 90L/h, whixh is quite less but not a real handicap. Changing it may give you 2ºC better perf. The 120mm rad is the way to go IMO.

Glad you like my comp 😉
 
k then...looks like my delta is 10C at idle and about 16C at load...not too bad considering i have $60 tied up in this whole thing...and that was shipped to my door 😀
 
ok i just got done lapping the waterblock and i'm down to 39C at idle...dont know what my load temps are yet...gonna check that in a min...i bet my temps drop somewhat in a couple days, though...since the thermal paste will set

All good reasons to go for it. 🙂 2c increase? How and where is your rad positioned?

it is in the side panel of my case...right where the fan going into my cpu duct was...the fan is on the outside of the case, the rad is on the inside
