Need help on my loop de loop H20 build

[Lu(ky]

Hey guys new to forum. :D I am getting ready to start my new build soon. I am wondering what would be the BEST loop(s) possible in my build. I will be using a Lian Li PC-S80 case in this build. I have been modding it for a while now. I am hoping to get this case on the front cover of PSU magazine. Anyways I need some input on my loop process. I will be using on the top of the case a BlackIce GTS360 and in the front of the case standing upright a BlackIce GTX240. And I can add a third radiator a GTX120 to the back of the case if I have too.
Will a BI GTX240 be enough to cool or will it produce allot of heat on the i7-920 1.35v on a Swiftech GTZ? Reason why I ask this will be my intake fans on the GTX240 with a push/pull 78CFM blowing into the rest of my case from the front. If it does produce allot of heat I was thinking of going to the last configuration at the bottom. I am thinking I need to push the heat loads out of my case as much as I can specially from the eK 4870-X2 block. What do you think?

Loop #1 BI 240GTX - Swiftech GTZ - 355/XSPC Acrylic Reservoir - repeat
Loop #2 BI 360GTS - eK4870 X2 - 355/XSPC Acrylic Reservoir - repeat


or -----> BI 240GTX - Swiftech GTZ - BI 120GTX - eK4870 X2 -355/XSPC Acrylic Top (http://www.performance-pcs.com/catalog/index.php?main_page=product_info&cPath=59_439&products_id=22700) - BI 360GTS - 355/XSPC Acrylic Reservoir (http://www.performance-pcs.com/catalog/index.php?main_page=product_info&cPath=59_439&products_id=23357) - back to beginning (This last one will blow all of load HEAT out of the case with this last configuration)

The 240 GTX will handle the i7, you won't have the most ideal temps in the world, but it'll work if that's all you're shooting for. Temps will be better than stock air, but again, it won't be ideal either.

Can we get some pics of this case? You've peaked my interest.

all those Rads need high flow fans to work right .. Soo ask yer self where is the hot air gonna come out @ ... even if have to put a Vent in side of the case ya goota exit that hot air
what is on the 360's loop ? & what pumps are u using ?
we ...... as in the Experts here @ RR ........
Will need more info sooo we can help ....
& we do want to help .........

I found a review of this case here:

http://www.dansdata.com/llpcs80.htm

It certainly looks like a 120.3 in the top and a 120.2 would certainly fit in the case. I am not sure about the spacing of the front two fans, but assume you can make it work.

I would use the 120.3 for the CPU as it would benefit the most from the colder water. My experience is GPUs are volt limited and colder water does not necessarily mean higher overclock.

Also, Most GPUs are designed for hotter temps.

I do not see much room for pumps or reservoirs. Are you sure you want two loops? You may want to try a single loop with both rads first to check it out. If you are not happy with the temps you could always add the second pump and res.

@Bigslappy, it looks like there is a vent on the side panel to help exhaust the hot air.

All the fans will be at 78 CFM on the intake with a push/pull and the top fan will be the same with a pull. And the pumps will be these 2 x Swiftech MCP355™ 12 VDC Pump with the following links in the first page.

I am aiming at this last configuration but not sure if my 2 x Swiftech MCP355 12 VDC Pumps can handle this setup?

BI 240GTX - Swiftech GTZ - BI 120GTX - eK4870 X2 -355/XSPC Acrylic Top (http://www.performance-pcs.com/catalog/index.php?main_page=product_info&cPath=59_439&products_id=22700) - BI 360GTS - 355/XSPC Acrylic Reservoir (http://www.performance-pcs.com/catalog/index.php?main_page=product_info&cPath=59_439&products_id=23357)

The reason I like this setup is it pushes the heat loads out of the case. To start my first heat load will be the i7-920 1.3v and go to the BI 120GTX out the back of my case, then to the eK 4870X2, then to one of the pumps to the BI 360GTS top of the case heat load out of the case then back to the other pump and we start over to the BI 240GTX

No problem with those two pumps in series with that loop. I have even more in a loop with only one of those. I do not think you need the 120.1 though.

The temperature of the water will eventually reach equilibrium and be constant everywhere in the loop. Loop order does not matter.

Have you tried Martin's Flow Rate Estimator Spreadsheet to calculate the flow rate of various components?

I find it useful for just such questions.

Here is some more quick pix. You can see I have plenty of room in the picture for BI 240GTX and the pumps. I thought I had a BI 120GTX it is a GTS. I think after hitting my i7-920 the heat going to the ek-4870X2 block will be allot of heat. So using the 120GTS after the i7-920 sould help? The 2 pumps working together should work you say?

[Snyxxx]

I see you gutted the case nicely. Plenty of room.

Did you try the flow spreadsheet?

[Septim]

still looks roomy in there... enough for thicker rads...

i would just look for exhaust vents, if most of my rads are pulling/pushing air into the case... the rear 120 rad you could probably do without...

[Lu(ky]

After hitting my first block Swiftech GTZ (i7-920 1.3v) will this produce allot of heat YEAS or NO? If it does why would I send it after this block to the eK 4870X2 block to add more heat to that block?

My thinking is after each hit of a block I would send this heat to another radiator pointing outside my case. See picture below starting point is number #1 with the BLUE lines represent cool water after hitting a block line turns to RED meaning line now has hot water after that hitting a radiator cools it back down to cool water again.

(1) Black Ice GTX240
(2) Swiftech APOGEE GTZ (i7-920 1.3V)
(3) Black Ice GTS120
(4) eK 4870 X2 Full Block
(5) Swiftech MCP355/XSPC Acrylic Top
(6) Black Ice GTS360
(7) Swiftech MCP355/XSPC Acrylic Reservoir

Look, I know what you are saying and it makes perfect sense. But, the temperature of the circulating water is what matters.

I have put in-line water temperature sensors everywhere in my loops and the difference is only 1°C at the entrance/exit odf the radiator which should be the biggest differential.

The water will eventually (a few minutes) even out and loop order does not matter. Try it yourself, do some testing and experiment.

[Lu(ky]

Yeah here is another picture without using the 120GTS and other pump. Only using the BI GTX240 & BI GTS360 and one pump

BI GTX240 ~ CPU ~ GPU ~ BI GTS360 ~ PUMP ~ back to start

i would suggest avoiding criss cross loops...

you may want to reposition the 2nd pump and do it series... then to both radiators and then cpu to gpu and back to res top ddc...

I am really starting to get confused :confused: Guys tell me do not go from CPU block to GPU block. Let try this question by question.

(1) I would like to know if the water going through the GPU block then to a radiator will put heat back into the case from the fans?
