Is this to much pressure???
 

Hey guys, Im back, I had some windows problems :(

Anyways, I have a pressure gauge attached right after my pumps outlet.

It reads a steady 8ish PSI...

Is that to much? Does anyone else us a pressure gauge?

My pump is really powerful, so flow is real good.

And my temps are now at about 35c CPU, and 40c GPU

Thanks ;)

That sounds about right. It's on the high side though.

What size tubing are you using? if 3/8, you'd benefit from the 1/2 upgrade.

What pump? what WB?

Need more info...:drool:

Im using the Flotec 350gph, Im using 1/2 already.

I have hte Maze3 and the GF3 block, I here the gf3 block restricks flow.

I alsto have alot of 90s and T Fittings.

try removing the 90's and T's (or as many as you possibly can) and see what the pressure drop is (and hopefully a cpu temp drop)

I almost forgot your pump... That would be normal for it.

Like Brad said, you should really try to eliminate 90D bends. Your pressure will drop a little bit.

You didn't mention if you were running the blocks in series or parallel. If series, switching to parallel will reduce the pressure, and increase the overall flow.

If you're already in parallel, then there's not much you can do...

Have you had any leaks yet?

can anyone explain series vs parallel or know of an article

A pressure of 8psi is 18.45ft of water and ,unless I have my silly hat on , this is much higher than the Maximum Delivery Head of many many competitor's pumps. For example: Eheim1250(max flow ~300g/h) Max Delirery Head 6ft 7in; Eheim1060(max flow ~600g/h) Max Delivery Head 10ft 2in.

have you seen his pump? it's a monster! I'm not suprised it's delivering that sort of pressure:drool:

series has the water flowing through one block, then the other, and so on, in a line.

parallel has the water being split before it reaches the blocks, so the overall flow is divided between the blocks.

So, does that mean people usually do series if they're only cooling one device such as the CPU and parallel if cooling more than one device (CPU + GPU)?

If their just cooling the CPU then it is series yes, that's prety well the only way to do that, when there are more than 2 things to be cooled it can be done either way (or a combination of both with 3 or more)

eg; CPU-GPU-northbridge (series)

/GPU\
--CPU----------- (parallel)
\northbridge/

Volenti,

Ahhhhhh. Thanks for your ascii art, it makes it a lot easier to understand. Is there a standard in which people choose to do series or parallel when cooling 2+ devices? pro/con?

Series vs. parallel
 

Some good discussion (and data) here:

http://forum.oc-forums.com/vb/showth...eries+parallel

summary: the decreased resistance from parallel plumbing will not typically counter the increase in temps from cutting flow rates in half. Series is therefore preferred.

but if you already have a powerful pump to counter the decrease in flow rate..................................

Then you don't need to run parallel since you have enough head to push through a series setup:D

jokes aside, I can see suituations where parallel would give better results than series, say you have a 1/2'' cpu block and want to add a gpu block, for whatever reason you can only get a 3/8 or even a 1/4'' block for that. Surely it would be better to *steal* 20% or so of the flowrate from the cpu block(running both in parallel) than to run them in series and reduce the entire system flow to 20-30% of what it was.

HUH HUH U said Head preassure...... HUH HUH hUH

Fixittt,

hehe, the good ole days before that show got cancled :)

Would you consider the Eheim 1250 (300Gph) pump one of those strong ones where series would be good enough or would running parallel be better at cooling the chipset, gpu, cpu? (probably just cpu/gpu for now. the chipset on my Abit KR7A doesnt seem to produce anything worthy of being watercooled). BTW, it will be in a 1/2" setup

also, when we say 1/2" are we talking about the OD or ID? I just recently found out what those (ID/OD) mean; i told you i was new :p

yea that would be fine(series), you just need a low restriction 1/2''(OD) GPU block, don't let my hypothetical ramblings confuse you, I'm a bit anal that way:p
