how much radding do you reckon i will need after my q4 upgrades?
here is what i want to watercool:
2x 8800gtx's (gonna be highly overclocked),
4x 1gb ocz flex xlc @ 1200mhz 2.4v,
C2Q6700 @ around 3ghz i hope :)
my striker extreme (http://www.aqua-pcs.co.uk/index.asp?function=DISPLAYPRODUCT&productid=701)
so, im going for 2 120mm rads with HIGH cfm fans (200cfm) and a dual rad with med cfm fans (100cfm).
Do you reckon i will need more?
many thanks
tek
 
Are you cooling the ram?
If you're actually cooling all of that, TN's on the right track: you're looking at least 5x 120mm worth of rads, if not dual 360s
 
sheesh, well, would triple 240's be enough? im looking at the tagan black pearl case, if i empty the HD racks out the bottom i should fit dual 240's in there and a 240 up top?
thoughts?
yes, everything will be cooled :)

Add up the estimated amount of heat your components will generate. That will give you a rough idea of how many radiators and how big they'll need to be. An average 1x120mm radiator will dissipate 150W of heat with medium CFM fans, 10 water/air delta, @ 1GPM.

8800GTX = 200W x 2 = 400W
Q6700 = 125-150W
Chipsets/Mosfets ~= 100W

Throw everything together and you'll need to cool about roughly 650W. 650/150 ~= 5

You'll need a 3x120mm radiator and a 2x120mm radiator to cool all of that.
 
Ranker, that means I'm pushing it on my loop:

8800GTS (to be overclocked) + E6600 (to be overclocked) = ~350W max of heat (using GTX and Qxxxx values) being cooled on a dual rad @ 300W of heat being dissipated.

:confused:

the E6600 doesn't push that much heat. If you're pumping 1.5v to hit that 3.6GHz, then yeah, you'll break the 100W barrier and edge towards 125W. The C2D's just aren't as hot as the Quads. The 8800GTS put out about 150W if I remember correctly.

You're close, but you should be ok. Worse comes to worse, just buy stronger fans.
 
Thanks for that clear up :)
im going for 4 rads on high CFM fans for now, all i can fit, then if i need more i can always add them.
cheers

You know you can purchase 2 MCR220QP's rather than 4x MCR120QP's or whatever brand you decide on. You'll save some money like this and make your tubing runs a lot easier to manage.
 
All those components and you're just going to run the processor around 3ghz? Ha, seems like a waste to even watercool it since it'll prolly do 3ghz on stock vcore.
 
i didnt want to be shouted at for presuming an overclock. the main idea is to waercool my gfx cards, but cpu n mobo too is nice.
ill try for around 3.5ghz, or higher, depends really.
so what do we reckon on that rad n ram?
 
Well, I agree. The CPU is so much heat that it should be watercooled. But just to hope around 3ghz is kinda weak. Especially after how many rads you're considering.

someone read 4 posts above!!! 1 rad possibly.

Although I've never owned that rad, I'm conjecturing that you'll need a strong pump to push through all of that. Forget about mounting that radiator internally as well. You'll need a wall in your room to mount that. I'd honestly be wary of anything made by Alphacool righ tnow. It's not that their products are bad as I use plenty of their products. It's due to the company's uncertain status at the moment. If the company goes belly up like many are speculating, you'll be up shit's creek without a paddle if the product requires a RMA.
 
yup, i can see what you mean, there's another rad, looks identical, by a different manufacturer, so ill grab that.
Im thinking of a laing D5 and mounting it on the case door?
Do you reckon i could use passive opperation?

I personally wouldn't go with anything less than two DDC's in series for a radiator like this. It might work passively given you're only aiming to cool your quad core, but I've never been a fan of passive radiators. My experiences with the Zalman reserator weren't positive.
 
would 2 d5's not be enough?
im not familiar with ddc, could you supply a link pleasse?
thanks
 
D5s are fine, though the DDCs do have some advantages.

SystemCooling's MCP350 (Laing DDC) review. This is the same pump that was used for cooling the 2.5 GHz Mac G5. It can be modified to heighten flow performance by various means -- check out Petra's acetal top, for instance.
 
so which would you recomend, that laing ddc or a d5? i want it to be small too.
 
jeez have rads started to suck that bad lately ? My god these are not P4 furnaces any more.

Yes that one rad will rule them all. Plan out your fan mounting and shroud, lots of room for a cool custom mounting there. Take a look a the AC ryan mesh panel, if I read the details right it should be big enough to cover that rad and give you something nice and easy to mount fans to. That rad is like 17inches x 15 inches aprox .
 
what order would you guys run the loop?
pumps---rad---cpu---gfx1---gfx2---mobo---res?
cheers
 
ok, so cpu, mobo, gpu?
ive heard the acrylic on the mobo blocks is bad, should i remove them from the plan?
