    Mods, this thread is about fitting a watercooled system in a new case, if possible without modding. So if i choose the wrong place to post this, feel free to move it where it belongs!

    Hi everyone. I got tired of looking at my stacker 830 with a 120.3 hanging on the side (the way my girlfriend looks at my rig isn't helping either) and finally bought myself a bigger case, the Lian-Li A71F. Was 150$ at ncix.com, and i just couldn't resist.:rolleyes:

    Now my question is, does anyone have this case watercooled? I spent a few hours searching for a build log on the net, and i just can't find pictures and clear explanation, just people projecting to install this and that. So i'm turning to the place i bought half my watercooling set-up, TPU!:rockout:

    This is what i'm using right now, and everything is working beautifully:

    Cpu loop (i7 970, currently running at 4300@1,424 vcore)

    -Thermochill 120.3 thick rad
    -6 coolermaster fans in push-pull (1500 rpm, can't remember the cfm)
    -Apogee gtx cpu block
    -MCP 350 pump

    Idle temps are 25ish, intel burn test in the low-mid 60s (except for one core who's in the 70-71. Is this 7-8 degree difference normal by the way?)

    GPU loop (cooling 3 gtx 460 768mb, running all at 910@1,087v)

    -Swiftech MCP320 slim rad
    -Three swiftech mcw60 in series
    -MCP-355 pump
    -Three noctua fans pushing air (1500-1600 rpm, also can't remember the cfm:shadedshu)

    Idle temps are really close to room temp, 17-20 degrees C, while folding the first gpu is at 48, the two other are running at 50 degrees.

    I run the two loops from a XSPC dual bay dual reservoir.

    Now i'll have to fit all this in my new case, and i've got two other radiator i could use:

    -Slim 120mm swiftech rad
    -Black ice gtx240 thick rad
    -plenty of fans to run them in any possible configuration

    First question: Am i gonna see a (huge) difference from running my cpu with the thick 240mm instead of the 120.3? I bought this cpu to fold, and my overclock is limited by the cooling, so any drop in cooling performance will lower my ppd. Not good! :laugh:

    Second question: would i see a huge gpu temperatures increase if i were to run all in a single loop? I know with temps in the high 40s-low 50s i've got headroom, but i don't want to see them fold over 60c, as other area of the card could get quite hot, considering my blocks are now full cover ones.

    I would like to have some proposition on what kind of loop order should get me the best temps (keep dual loops, put that rad before that block, etc.) and how i should fit them in the case. I almost sure i'm gonna have to buy a dremel before i start (i got experience in the watercooling department, but close to nothing in the modding one), and it seems that any modder without a dremel is no longer a modder!:toast:

    And to finish, the least pieces i'm using, the bigger my for sale thread (and ultimately, my wallet) is gonna be!

    On a side note, is 70A (TX850) enough for everything? It is currently running strong, but i don't want to blow anything (and if i have time to wait for a good 1000w to be on sale, that would be great!)

    Ok. I've heard from someone on another forum that the psu is at it's limit, but should do it. What do you think.

    And could a a71f owner tell me if the front fan are 120 or 140 mm. I've read post and reviews featuring both, so help me clarify that!

    No watercooling comments of any kind? Anyone?

    Check my system specs, my rig is probably eating more power than yours (owing mostly to the GTX470s being power hungry) and works just fine with a TX750. I cannot help you out with the WC as I've never seen that case before.

    Thanks for your sharing your experience. We should be in the same watt range, as i've got 3 gpus instead of 2. Under full load (cpu+both gpus), is you power supply exhausting hot air? By hot i mean you can defenitely say the air is HOT, not only a little.

    Oh, I missed that 9600GT. I still say you're fine, though, seeing as your PSU is beefier.

    IIRC, I did not notice anything particularly hot about the PSU exhaust when under load. It is warm, but not HOT.

    I ran dual 4870X2s and a quad plus my watercooling which is a bit more involved on an 850W thermaltake. You are more than ok with that PSU.

    I forgot to change my systems spec: as i said in my original post, i run 3 gtx 460 768mb, highly oced and overvolted. Those alone should count for 400-450 w. But i believe you're both right, 400w for the cpu+hard drives+loop should be enough.

    Well i'll have to update this thread, as my power supply went up in smoke yesterday...

    Got home only to smell something i was not recognizing, then start the rig and see some light and a cloud of smoke coming from the psu...

    Guess we were wrong! RMA already approved by corsair, i'll se what they send me back.
