hello

names vicky and im new to the forum and came here for a little bit of advice on water cooling.

basically i have bought the following items second hand, all were good working order as the computer was running when i 1st looked at the parts.

parts i bought were

xspc 750 dual bay pump and reservoir combi
1 x 240mm rad made by xspc
i amd cpu block and fittings
i radeon hd block
1 x phobya 200mm rad
enough tubing and compression fittings for the whole system. 6 metres of unused tubing as well.

what im looking for is the pump powerful enough to push enough water thru all the tubing, radiators and blocks or would i need a mre powerful pump. dont fancy me and my boyfriend building it all up to find out its not strong enough.

also i presume it shall be enough to cool an fx 6300 and a radeon hd 7950

thanks you
 
the 750 is an ok pump not on the class of the d5 or ddc but it should work fine with your system. What exactly are the gpu and cpu blocks that you have as their restrictiveness is relivant
 
the amd cpu block is the raystorm the person i bought if from said he bought it as part of a bundle of this website and the gpu is an ek-csq, its clear plastic type stuff with circles on it
 
should be fine then those blocks are high flow so they arnt very restrictive. Throw it all together and dont forget to take pics
 
so you definately think that one pump will run that ok??you see weve never tried this before and dont fancy ripping the pc apart to find out that it doesnt work. how will i know when its all together if its pumping water quick enough?? i presume the temperature of the cpu will let me know??
 
Use cooling configurator to check the block does actually fit your 7950 too.

750 pump res will easily manage that loop.
 
Yes temps are an indicator. Although the difference between .5 gpm and 3 gpm only relates to less than 5 degrees difference anyway so you probably wouldnt notice, you could buy a flow meter but personally i wouldnt worry about it
 
the gpu water cooler was already attached to the card in the person selling the stuffs system, i also boiught the card in case your wondering, i had a read on the internet last couple of days and there was conflicting reports as to whether the pump would be powerful enough to push the water through the 200mm rad as well as everything else as as i said i dont want to build it up to find it doesnt work properly

also on a side note when i bought the stuff the guy had opened the cpu block and removed the silver resister inside the block and couldnt find it, he claimed that all it did was restrict the flow of the water and ran better without it. will this turn out to be a problem?? my boyfriend has opened it up to have a look and doesnt think it will affect it and there is nothing on the internet regarding the piece of metal

your referring to the jetplate id look to see if you can get a replacement although not needed the do improve the performance of the block
 
exactly as its name it is a plate with a small hole cut in it which jets the water into the core of the block, run a kitchen tap and it provides a steady flow now stick you thumb over it covering half the tap, same principle.
 
ok ive got you now so would it not be better without it then? im assuming thats why it was removed to give a better flow of water or is that not how it works?

anyways are you completely sure that my pump will definately be enough to pump water around my entire loop??

next question ive read that its best to have tubes as short as possible how will i work this out as i will need to put the 200mm rad in the bottom front of my case and is it ok to use a few 45 and 90 degree angles as well as thats mainly what i have
 
No because you want the pressure in one area rather than spread over the whole block

in the kitchen sink it doesnt mater as you say the sink still gets filled however a cpu block is different the bit that matters and does the cooling is smaller than the whole block say youve got 2 buckets a smaller one and a larger one on top with a small hole in the bottom. you can fill the bigger one up with a wide jet and let it drain through to the smaller one or you can "jet" the water so you get the same flow but higher pressure so it fires through the hole to the bottom bucket rather than wasting pressure and flow filling the top bucket first, the bottom bucket still fills just less efficiently as your filling the top bucket first

Yes its best to have tubes as short as possible but youve got to be realistic it just means dont leave feet and feet of excess tubing run it in a logical way so your not wasting any, 45 degree and 90 degree fittings are fine just remember the more you use the more pressure will drop, like filling the bucket with 3 bricks placed on the hose

thnx for the replys im going to give this a bash this evening with my boyfriend however he is still unconvinced that the pump isnt strong enough to pump the water round at an acceptable rate
 
it will be fine the 750 will push up to 750lph with up to 2meters of head pressure a 9.5kw power shower only shifts around 300lph
 
thanks stuie just started and already ran into our first problem. looks like were going to drill some holes to line the 200mm radiator in the front of the case

Without using an analogy, it forces the water through an orifice causing turbulence, the turbulence in the water going over the fins inside the block improves cooling performance, however it also adds restriction to the loop which is probably why it was removed.

Imo you shouldn't worry about replacing it with an FX-6300, I'm not trying to disrespect your CPU, its good, its just that the performance difference we're talking about is only a few degrees, which is usually more important to people with high end processors pushing the overclock.

With your CPU its not really going to make a noticeable difference, and leaving it out will make life easier on the pump (by lowering the restrictiveness of the loop, and therefore the head pressure required to get X result).
 
managed to put all the stuff together along with the new graphics card, was actually pretty straight forward tbh. not sure what sort of temps to expect however both cpu and gpu are sitting idle at 26c so cant be that bad
