X2 4800 + 7800 wise idea or not?

[Usurper]

well i have nearly finished building my new system, (just awaiting 4800)

i will be watercooling the cpu (Eheim 1048,1/2 tubing,TDX block,black ice extreme rad, double bay res) if i added a 7800 to the loop would this hinder my overclock on either the cpu or gpu? i have watercooled before ( and briefly vapochilled) but only ever with the cpu in the loop. just curios before i go to try find a 7800 block.

chrz.

[a5h]

it should be fine ...only the pump is kinda weak. and the TDX needs high flow rates.

it will hinder the overclock of the CPU slightly, but then again will increase OC on the 7800 over air cooling :)

[alexio]

A stronger pump would help a lot ;)

[Usurper]

such as?

i would say go with a bix2 at least.

[Usurper]

Not sure ill be able to find any of thoose in the UK, stupidly i was under the impression a mains eheim was one of the best :(

As others have said, your pump is a bit weak for the CPU-block used. At a minimum, switch over to the 50z. All the recomended pumps should be readily available in the UK, if you know where to look. Also switch over to at least a double size radiator [ie: BIX2 instead of a BIX1]. DangerDen recently dropped the price on their rads, some nearly 50% off. If you do go with an X2 CPU + Nvidia GPU you will probably want to step up to a 120.3 style radiator or one of Weapon's HeaterCores. Both the CPU and GPU dump a lot of heat.

[Usurper]

OK i just bought the Black ice extreme rad so reluctant to sell when it hasnt even got wet.(also great fit in case)
what about the 1260 eheim pumps?

[BRiT]

If you just bought it from a store, return it for an exchange to a properly sized one. I'm not sure the BIX.1 will even be able to handle the heat from the X2 CPU.

[jellybeard999]

id advise....

upping to a thermochill pa160, 120.2 Thermochill, or 120.2 BIX AT LEAST - www.over-clock.co.uk / www.overclock.co.uk

getting a aquaxtreme 50z - www.extremeprometeia.co.uk

[aznblueeboi]

yea...the extreme is a nice pump with good flow rates

[Usurper]

The Thermochill rads will NOT fit in my case, pfft begining to wish i hadnt started this now hehe
I cannot change the stuff as it was mostly bought off ebay.( seems only the pump and rad are your areas of trouble) i will try and get one of the pumps.

not happy about the "I'm not sure the BIX.1 will even be able to handle the heat from the X2 CPU" quote :(

i am assuming if i just leave the out the gpu, that the rad i have and the 50z will cool the cpu ok?

[WeStSiDePLaYa]

i had the chenming which is almost indentical to your case and i was able to fit a bix2 with 2x35mm thick fans on it, ALL internal.

[BRiT]

If its just the X2 CPU + 50Z and a single 120mm fan BIX, then it's still possible the heat dump from the CPU will overload the radiator. Over time the water loop will keep heating up. It may end up no better than normal AIR cooling. All depends on how much heat-dump the X2 cpu produces.

Not possible really.... radiator gets more efficient as temp delta of water and air goes up. It will stop in reasonable point. Even with peltier in the loop, it will be extremely hard to see these type of radiator going 20c above ambient. You will most likely be near in range of top end air cooling at same noise level most likely.

[MaxxxRacer]

not reading the above posts i can most certainly tell you a single BIX and 1048 pump will hardly handle the heat from both an X2 and a G70... that is jus too much heat. a good pump to start with is the D5 or AQX50Z. and a good radiator is the BIX3 or HE120.3, or a weapon modded 302 heatercore

[Usurper]

how do i close the thred?

ive contacted 2 people who have overclocked 4400 and 4600 with similar systems with no trouble, ( 1 even without a res )

[MaxxxRacer]

you dont close the thread. the thread is open to anyone who wants to add any further information, comments, or experiences.

btw a res wont get you better temps. infact it will net u slightly lower flowrates...

[Usurper]

ahhhhh well that could make a big big difference

if i got rid of the bay res i could put a bix2 as i have roughly 11inches head room.

whats your opinion on that, would i need anything extra?

[WeStSiDePLaYa]

???

I havent mentioned which case i have

didnt you have antec amg in your sig before?

[Usurper]

noooooooope.

i have a cm stacker, with 6 bays for wc stuff at front.
this is a total headf***.
was sure i was doing A, then it turned to B, i think at current im on about F.

TDX block is staying, 50z pump is on the way, i could fit a bix2 IF i loose the res. but i dont know if i need extra tubing to compensate for the loss of fluid ( i know the fluid will warm up to the same temp, in a case of this size )

[aMp]

You've got a Stacker and you're short of room?! What do you have packed in there, an Antec Sonata? Sheesh, I've got a full-sized 2-199 hovering over the giant intake hole in the bottom of the case, with tons of room to spare all around.

Don't freak about the heat output of the 7800GTX. It's actually lower than that of the 6800 Ultra -- still hot, admittedly, but far from unheard-of.

Also, your water temp won't change much between a T-line and a res. Over time, temp depends almost entirely on the cooling capacity of your heat exchanger rather than the volume of water in the system. On the other hand, it's true that a res will lower flow rates a very small amount, but since you've upgraded to the 50Z it won't be a real problem -- maybe a 0.1C difference. So make your decision based on the limitations of your case and ease-of-use instead of performance. Personally, I find reservoirs much easier to work with than T-lines, especially because I tweak my rig so often and T-lines can take hours to bleed. But that's just me.

Have you considered mounting a PA160 to the top or bottom of the case? It would require a little case-cutting, but that's not as difficult as it might seem. And even if you screw something up, Cooler Master will ship you a replacement panel for a reasonable price.

-aMp-

[Usurper]

Thanks for all that.
I have the top panel in top slot then dvd/fan controller/space/dual bay lcd/as the fan controller is custom made and the lcd is loaded up wire wise, i cannot use the bays behind them.
i pretty much wish to use the case as is ( ive been without my pc for over a mth now and i dont want to waste anymore time hehe.)
I think i should change to a BIX2, as i can add the gpu block when im ready then.
i just need to think long and hard about this. but tbh its driving me nuts :(. BUT then again im always like this before i upgrade etc.

[BRiT]

The Stacker unmodified has room enough for a BIX-2, maybe even BIX3. Just put the BIX-2 or Weapon-HeaterCore on the bottom of the case ontop of the bottom intake. That way you won't use up any front 5.25" bays. There's plenty of pics of WC'd Stackers in the WC Case Gallery thread.

[MaxxxRacer]

u can use a BIX3 but only if u only use one cd rom bay.. ive seen it done before...

a BIX2 would be the better option of the BIX's if u want to save drive bay room. As brit mentioned a weapn heatercore will fit aswell and have better cooling capacity.

[Usurper]

It looks like ill go BIX2 in the front of the case.
would you recommend 4 fans or just 2 more powerfull? i have 2x YSTECH 120mm fans here.and 2 slower fans that came with the stacker.
slightly concerned about the top 120mm fan will be blowing across the 7800 in the oposite direction to which the 7800's little fan is trying to blow, will this cause a problem?

50Z>TDX>BIX2>maybe res that order is ok ?

Is this still only sufficient for cpu cooling or can i gpu cool also?

[aMp]

You'll be able to cool both CPU and GPU just fine with that arrangement.

Don't use the Stacker fans, they generate about as much airflow as a moderate fart. Depending on the model, the YS fans should do fine. If you're willing to drop another few dollars, a common arrangement is two 120x38mm fans (generally Panaflos) wired to a rheobus; high pressure fans that can whip the air when needed and be quiet again with the twist of a knob.

The push/pull thing is still contentious, but the general conclusion seems to be that a 4-fan push/pull arrangement will perform slightly better but at the cost of more noise (depending on fans, rheobuses, etc.). Most people don't bother, and just go with a shrouded pull arrangement.

The order looks fine. Some people recommend going res>pump>rad>cpu>gpu, but it probably won't make any significant or even measurable difference. The only definite I've found is to keep the res right in front of the pump.

The only thing I don't get is the question about the 7800's fan. Aren't you watercooling the card? And why would it make a difference? Pics?

[pablo]

now the funny part is what if it cools you 7800 below 35c? dont know what temps youll get but what if? cold bug?

[Usurper]

Thanks aMp.

Ive used shrouds and the ystech fans i have push 120cfm, i have a custom made fan controller so i can slightly lower the volts if needed, ( itll all depend on temps )

I am currently leak testing out of pc, ive added a maze 4 gpu block and as soon as i get this setup ill post pictures and clarify what i meant with gpu fan.

thanks again for all ya help guys, ill post late tomorrow or friday.

[Usurper]

Well after having loads of trouble with the "cold bug rubbish"

and after a updated bios.

im up and running, :woot: gpu is at 500/1300 and the X2 4400 is at 2585mhz. these were just 1st efforts, the new gpu bios doesnt allow the temps to be shown, but the cpu temp is idle around the 30 degree mark, going to roughly 36 under load.
anyway thanks for the tips, im off to clock em both to hell and find thier limits. :D

[MaxxxRacer]

nice. what cooling is on the gpu and cpu?

[Usurper]

DD Maze4 acetal Gpu and DD tdx Cpu

[typer77]

I just finished building my system with the stacker.
I have the BIX2 in front and it left me with only 1 drive bay for DVD and the HD cage that came with the case. On the BIX2, it was fitted with 4 120 fans that I bot from Dangerden. The entire unit was ziptied.
Eventually, I will move it to the bottom to free up some drive space. but I don't want to give up too much battlefield2 time now. :D

[thelostrican]

bix2 or a bip2 should be more than enough for an x2 and a 7800...i use to run an fx55 and two 6800 ultras in sli with a pro2....being that the fx55 runs hotter than the x2 and a 6800 ultra is hotter than a 7800....
get a better pump and try with that rad, personally i would go with either a bip2 or a pa160.....
