for the most part, you want the pump pulling water from a ready supply of water....aka the resevoir. This way you avoid any chance of cavitation of the pump causing lots of bubbles to circulate through your loop.
the ideal loop config would be:
resevoir -> pump-> cpu -> radiator ->...
restricting the outbound water flow is fine. Any pump 10GPM or lower will be fine at .1gpm flow. What you do not want to restrict is the inbound flow, ie from the resevoir to the pump. I recently changed out the piping from my radiator(car radiator no need for a resevoir) from 1/2"ID tubing...
for most people the Eheim 1250 is more than adequate, along with using 3/8"ID tubing.
Resistance going through your system is the main point. Resistance is measured in head/ft. The higher the resistance the lower GPM rate you get. Resistance depends on a few things. How many waterblocks...
Just a little comparo between the two pumps....
Pump I have now
link to Mag9 pressure curve
Pump I just bought
link to i40rt pressure curve
Im giving up about 2.1GPM flow for almost double the max head/ft. I think it will be worth it. Im pretty sure that overall flow will improve...
all i had to do was remove that black thing, and the 2 mounts were already there. just screw the two posts in and slide the waterblock on and follow the install...
washer - spring - washer - nut (on both sides) and then just alternate tightening....
piece of cake.

no, i dont know where the piece fell off to. Yes, i know Mouser.com sells that kind of stuff, i just need to know the specs of the capacitor so i can order the correct one.
Its an SMD Capacitor, just dont know which one....

Some more pics. Dont mind the mess =]

You can see the New 1"ID tubing coming into the pump and the bypass valve

my 2800+ is at 2.6GHz([email protected]). It booted at 2.7GHz, but wasnt prime stable and i ran out of voltage for the vcore adjustment. dont limit yourself to just the 3k+. Althought i wish i would have a 10x multiplier....

I have a 9700 Pro, with a busted off SMD Capacitor. here is an image link:
Busted
I don't remember how I broke this, but it is causing overlay problems with video. Its showing black dots at certain points of the screen, only while playing video, not for desktop use. Otherwise the card...
Its a pretty decent board provided you get a great cpu and ram. The top voltage on the Chaintech VNF3-250:
1.7 vcore (overvolts to 1.8)
2.9v for vdimm
1.9 for chipset
it actually booted at 2.7GHz but wasnt prime stable. I need maybe another .1v on the vcore. After testing 2.65GHz for...
I added a bypass into the loop. I also changed out the tubing from the radiator to the pump. Its been replaced with a 1" ID tube. seems to work a bit better. no restrictions going in now.... Between the two of them, it seems to have quieted my pump down a bit, but its still making...
I thought about that before actually....but i like the current setup, how it is now...
ive been thinkin about adding a bypass from the pump directly to the rad to releave some of the pressue. It would also pass the water when i disconnect the quickdisconnects so i dont have to turn the pump...
Thats 54C with no fan blowing over the radiator.....IE passively cooled rad.
I just got a radiator cap for it, ill see if pressurization makes any difference on temps or temp delta....
-Vi
Those temps are with a fan blowing on it. For some reason, even though the temps are under spec, it shuts off without the fan cooling the rad yet...Without the fan Load is 54C.
I think what happens is the capacitors right near it (the cpu) heat up with the extra 10C and extra voltage, and...
I guess no one cares about my project on this forum other than me. Consider this my last post about my system then.
Athlon64 2800+:
currently running at [email protected] = 2.65GHz
Idle temp = 34C
Load Temp = 44C
Have a nice day...

Well did you try under the main page, not the top triangle thing (low-level) but the second one should be Driver one. It should be in the AGP settings in there....
I tried to go back into it, but it was grayed out in mine...i swore it was selectedable in there...maybe ive been staring at to...
well yeah that great and all....
But which one yeilds more performance when you do OC it?
I know with the 9800pro, you saw a much larger jump in performance when you OC'ed the memory on them.
Im guessing its the same for the 6800's since the difference between the 6800NU and 6800GT's...
