Watercooling in a lian li pc71

jetjaguar · 02-18-2002, 03:16 PM

ok .. well i will be watercooling my northwood in my pc71 case ../ but i have a couple of questions ... first off here are my components ..

maze2 with socket 478 hold down plate ..
black ice xtreme
eheim 1250
1/2 silicone tubing ..

now .. im placing the rad up top connected to the blowhole ..
my question is where to put the pump and res .. i really dont know where ... i mean i know on the botton .. but the hard drive cage really takes up space ... that is why i was thinking of getting a combo thing .. like from dtek or somewhere .. but i would rather get an eheim 1250 if i could fit everything .. i want a res .. no closed loop .. not to sure on filling and bleeding the system .. res just seems easier .. can you guys give me some suggestions please

Really depends on how handy you are and what your motherboard looks like (where the connectors are, etc.).

I'm putting together a new system using the same case (such nice and roomy cases). If you can make a simple plate to mount the pump on, here is what I have in mind, may or may not work for you

Attach a plate directly above the bottom HD rack (the one that slides out the side.) Mount your pump to the plate. If your M/B and cabling allows it, you can mount the pump so it points towards the processor (it will over hang the M/B slightly). In this direction it will actually fit between the bottom HD tray and the top 5.25" drive rack (right in front of the little 3.5" tray that slides out the front)

Or, you can do the same general arrangement, but mount the pump to the plate so it points UP. In this case, the top of the fitting will be just in front of the lowermost drive slot of the top 5.25" drive rack.

Doing it one of these ways, you can still use the entire bottom slide out HD tray, still access the little 3.5" tray (since it slides out the front), and still have access to all the top drive bays

You can either attach the tray you mount the pump on to the M/B plate (if your motherboard is ATX size there will be two rows of unused mounting holes on the M/B plate) or you can attach it to the top 5.25" HD rack at the bottom.

hmmmm .. that sounds like a good idea ..
but where the hell does the res go ..

the most used place is generally at the front of the case, especially in the pc70, it is quite deep, so you won't lose any pci slots, even with a big rad and duct. You could have the pump beside the resivoir, both just behind the rad, or you could mount the pump in one of your 5.25" bays, it'll probably take up 2 or 3 of them though, you could also mount the psu right at the top of the case, and have the pump just under it, ontop of the mobo

well the rad is going up top .. in the center attached to the blowhole .. almost all my 5 1/4 bays are taken up .. so that is out of the question .. if i took out the hd cage .. i could fit so much ..
hmmm .. keep the ideas coming .. or any pictures of lian li 's with watercooling setups ..

where the 2x 80mm's are, next to the atx i/o panel

My Eheim is probably going here:

The m/b I'm using is 0.2" too wide to fit a 1250 there. (just a shade over 3.5" available in mine).

You could make the res the approximate size of a 5.25" drive if you have 1 slot free in the top cage. Then you could access it from the front

Or put the res at the top, between the front of the case and the radiator with a fill port going out the top of the case.

jetjaguar · 02-19-2002, 10:25 AM

phaestus .. how are you gonna mount it . ??
i was thinking for a res .. i would just get a 4x4x2 marine junction box .. and that should be enough ... and maybe put that at the top above the psu ?? and the pump where phaestus is .. and the rad uptop .. that should fit i hope ..

EMC2 · 02-19-2002, 05:15 PM

I would suggest putting the res to the front side of the case if you mount it up top, with the rad adjusted towards the back if needed. Reason being so that nothing blocks the two 80mm inlet/outlets at the top back of the case. I'm guessing that your fan is going to be blowing out on the rad. If you restrict those back two inlets, then most of the air going to the rad will be the heated air from down below, leading to higher temps. (besides, I try not to put anything directly over the top of the p/s, just in case. Water doesn't conduct low DC voltages very well, but the AC in the p/s is another story all together)

I don't know what Phaestus had in mind, but I use a drill, a bolt, nut, and rubber grommets.
