Dremel Time

SNC00100copy.jpg


If I could turn back the clock I'd have made the 24-pin hole wider and tucked it in further behind the mobo. The hole pictured above is large enough to get the 24-pin through but the angle to the motherboard means its a very tight fit getting it past it. Would be a lot easier with a wider hole and I'll widen it next time the computer comes apart. The hole at the bottom for sata cables is currently unused as cables are too short.
The 8 pin connector hole is perfect. Couldn't go further left due to the metal support thats there.
Silverstone's mobo trays are thick, took a few reinforced dremel discs to cut through.

Hole to route cables from PSU

Quite tough getting a wide enough hole to fit the thickest cables through. Cutting the hole right up to the edge of the mobo tray slot without cutting into it took some time.
Realised after putting the case back together that I could cut the side bar off (between the red lines) and it wouldn't be a problem. Next time its apart it shall be done! Had to dremel the hole from underneath:

Don't Trust Used Fatboys

A few hours into an earlier leak test and the tube on the pump output sprung a nasty leak, a litre of f1 sprayed everywhere. No electrics were harmed thankfully.
This was the offending fatboy:

The tube had been stretched and used before. That coupled with the awkward angle of the tube onto the barb must have caused the leak. I've learnt my lesson and have wormdrives on pump and rad, cable ties on all visible connections and clips on the bloodrage IOH (dont trust its soldered barbs)

Leak Testing Final Loop

I'd have liked the CPU to have come straight after the rad in the loop, but I couldn't have IOH to GFX as the tubes would unavoidably kink.

Love this case :)

Silencing the Pump Vibrations

The pump dampening kit you can buy does little to nothing to stop vibrations. But the metal block to fit the pump to is great and I wouldn't nest the bare pump on foam as it would warp and possibly melt it.

I originally cut a cradle out of box foam to mount the pump on, and stuck the cradle to the case with the sticky pads included in the dampening kit, but this cradle still transmitted most of the pumps vibrations:

I then cut most of the cradle away, and used layers of various bits of foam from components' boxes. Vibrations gone.

400 grit, all the way to 10 micron. Lapping Kit came with glass base.

Be careful when ordering 4870x2 make sure it's to ATI reference as there are a couple of newer models that have custom coolers and the board layout has changed, making it impossible to fit waterblock. Asus Tricool card which I bought first without knowing is one of these (thinking it was Asus's older reference car). Couldn't return the card as I'd messed about with it.

Then bought a Sapphire. Fidly fitting the waterblock. I did what EK recommended and applied the block twice, freshly applying as5 inbetween to ensure maximum contact.

got some ac ryan locking sata cables. great for component end of cable, but didnt fit in the mobo so had to cut off the locking clip and file down the plastic

zalman ZM1000-HP - this thing is as quiet as it gets

SNC00056.jpg


sorry log isnt really complete, was a gradual build over a few months, i ran a water loop on my old pc spec just to get used to working with water. then slowly added and changed things along the way.

few things of note:

The AC ryan cable braiding kits are a bit pants. the heatsink doesnt come in the right sizes for all the different braids, was far too big for the smaller braids used for fan wires etc. the murdermod cable braiding kits look far far better, failing that get your AC ryan braiding and heatshrink separately.

the lian-li bay mounted HDD rack doesnt sit right in this case, front grill protrudes a cm or so,

i managed to overload one of the 4 fan channels on my fan controller with an ac ryan quad fan splitter and it burnt out, pretty sure each channel could handle 4 fans but the cable had LEDs on each fan socket which must have overloaded it.

4 x 12" UV cathodes works well for lighting up case, i didn't find 2 to be enough. also tried 2 blue cold cathodes and 2 UV but the blue ones deaden the effect of UV quite a bit.

Not bad at all mate :)

I like the cut-outs on the mobo tray keeping things tidy, this and a v2000 water cooled I saw in the gallery is making me want to order some wc kit :D
 
cheers!

Am still struggling to get a stable computer.
4ghz w/ HT on - Prime stable over 8 hours. Temps maxing out at 87.
The problem is when I cut power to the mobo, then restart, the computer will fail to post on ANY overclock. Problem seems to be solved by making it fail to post in this way, then cutting power to mobo again. Then I can restart and it post again. Bizarre problem, will contact foxconn to see what's up.

I'm also seeing a big temp difference across cores after lapping. Looking at the final lapped pic above, I think I'll have to lap it again, completely levelling the edges this time.

Having the fan controller is fantastic, and I recommend it to anyone wanting a quiet build.
On full voltage the noctuas are quite loud. The dense grills of the tj07 don't help but to get anywhere near quiet you have to voltmod them or run them through a controller.
With all fans down to near their minimum spins, all temps are fine and the loudest things are the pump's whir (without the vibrations) and the hissing of the electrics on the gfx card.
I can't hear the zalman PSU fan over the pump or the gfx hiss.

It really is incredible the difference a quiet computer can make when listening to music.
Running from my emu-1212m to audiolab 8000A amp and Quad 11L speakers, songs have opened up a lot and i'm hearing things that used to only come through on my beyer headphones.

3.8ghz stable with HT enabled
prime95 for 8 hours, temps maxed out at 87 (hot hot hot)
that's +240mv on vcore and +180mv on vtt
bclk of 200
multi of 19

here we go testing multi of 20 for 4ghz,
temps have hit 86 in first couple of minutes of prime. i sort of wish i had separate loops for cpu/gfx. i can get a stable bclk of 210, and i have a feeling i could push 4.2ghz with HT on but i'd need the triple rad all to the cpu.

idle temps of 50ish, mid 70's when gaming

woooaaaah 90 on one core in first hour of prime (i need to lap this cpu again)

I'm no expert at watercooling, but it looks to me that you are trying to cool too many very hot components (Dual GFX, NB, CPU) with one radiator, and I don't think all the lapping in the world is going to get your temps to an acceptable level.

I think you might need to consider a second loop, but like I said i'm no expert.
 
yeah, the 4870x2 has pushed CPU temps up around 10 degs or so.
dual loop is something i may well consider in a few months.
but im getting temp difference of up to 5 degs between cores (after my first attempt at lapping) under prime @ 3.8ghz measured, 86,87,83,82 as max temps. sure enough sign that cpu needs reseat/more lapping?

gonna lap cpu again, reseat and see what happens!

worst comes to worst i'll stay at 3.6ghz @ lower vcore and keep things a little less toasty untill i make the decision to dual loop.

5 degrees between cores would seem to indicate that there is some issue with either the lapping or the fitment of the block, although it could even be poorly spread paste, but you're not going to get much lower than the lowest core temp is now, and that IMHO is too high.

I do think you'd be best to stick at 3.6 until you can get a 2nd loop running.
 
looks great can you take a few more pictures of the bottom of the case so i can get an idea space wise with PSU and RAD, want to see if i can push/pull the RAD and still fit my PSU
i also noticed your using the 92mm fans as intakes, ive seen this mentioned in another To7 thread why? i was going to use them as exhausts and fit a front fan aswell as the 2 top ones as intakes??
 
I have 2 Scythe Kama Bays in the front of my TJ07 and the 92m, fans exhausting atm, seems better than having them as intakes, i have also turned the top fans off as they mess up the air flow.
