No worries, there will be pics GALORE as I work through this and after I put everything together :)

I hope to have the whole thing up and running and be tweaking things before the end of the weekend.

General plan is:

1. Prep GPU tonight (mount heatsinks, etc...)
2. Assemble out of the case test loop for 12-24 hrs
3. Tomorrow put together full rig in the new Rocketfish case and assemble loop in case and perform in case leak testing with the computer off (obviously)
4. Sunday if there are no leaks I plan to go live!

After that, the final touches will be Voltmodding the 8800 GTX to get every last mhz I can out of it, and remounting/playing with the FuZion accelerator nozzle kit and try different nozzles and the included washer.

I may even leave some slack on the rad line to mess around with chilled water by submersing the rad in a bucket of icewater, although Im not really sure I want to play with that since I do all of my serious benching subzero and I have hard time believing I can achieve anything remotely close to what I get on LN2.

Ok guys, project is completed! Still needs ALOT of tweaking, but all of the basic constuction/assembly is done.

Full system is Q6600, P5K dlx, 8800 GTS G92, 2 X 1 gb mushkin PC8500, Corsair 520hx, 2 X 320gb 7200.10 in RAID 0.
Cooling is: D-tek FuZion with washer and quad accelerator nozzle, MCW60 + DD Fatboys + swifttech ramsinks, PA 120.3 + EK G3/8 barbs, D5 vario, Micro-Res + DD Fatboy barbs, Tygon 7/16ID 3/8OD

I have some temp issues though.....

Ambient is 24c

CPU idle is 44/44/42/42 (Q6600 9 X 400 for 3.6Ghz), and load with P95 small FFT is 68/68/63/63 at 1.46 Vcore in BIOS.
Thats the same as my TRUE 120 on my other case which I felt was a sweatbox.

GPU idle is 40C (8800 GTS G92) and load is 45C. Clocks are 800/2000/1100.

These temps are WAY too high IMH
I have bled the system, but Im sure there could be more air bubbles somewhere. Ive turned it every which way you could possibly think of and shaken it so much my shoulders are sore LOL.....

I have new fans on the way (Yate Loon 12DH-12 from Petras) that reviewed very well on the XS fan review to replace the Antec tricools Im currently using.

I think that my Radiator mount/placement could be an issue. From top to bottom here is how it is mounted on the top of my case on the inside. RAD -> Neoprene Gasket -> Fans attached with #6X1/2 inch screws -> Fans directly attached to top of case with fan case screws. Do I need a shroud to move the fans further away from the radiator? The fans are on top of the rad in a pull configuration.....would I get better results moving them to the bottom in a push config?

Also, the hole I cutout for the rad at the top of the case is less than perfect. Cosmetically it looks good since the radgrill is covering it, but I made a simple rectangle that was about 1/8inch smaller than the screw holes on the PA120.3 This leaves approximately 1/4 inch (or so..??) of fan on the periphery which is covered by the aluminum top. Is this significant?

GPU temps are ok, but I think thats likely because its a G92 and not a G80 and produces significantly less heat. I still think it should be cooler though.

Pics to follow later today! I still need a TON of wire management but didnt make sense to start since Im going to be pulling out all of the fans later this week, and wanted to settle up with temps first.

Thx!!

remove the d-tek, clean off the paste, and re-mount with vertical line drawn essentially between the two cores and don't be afraid to tighten it down if you're using a spring mount, you can basically crank them down till you completely crush the spring.

Ceramique was applied properly as per the AS website for quad cores. I also buried the pro-mount spring loaded screws AS FAR as they would possibly go. AS FAR as they would go!!! Hehehehe.

Ill try a remount later today, BUT....I also do not like my GPU temps. How could a bad CPU mount cause increased GPU temps?

Do I need to drain the system for a remount, or just be careful with everything and leave it all full?

Also, just HOW far off are my temps?

Im thinking I should be somewhere around....

CPU - Idle 35-38C, load, 45-48C

GPU Idle 25-30C, load 30-32C

Are those unrealistic considering Vcore 1.46 (BIOS) and CPU 9 X 400, and GPU 800/2000/1100?

With 24C ambients I would expect cpu idles to be sub 40 with full load on both cpu and gpu staying below 50 max, with more radiator than you could need there is a kind of 10-10 rule, 10 above ambient idles and 10 above idle loads but, you're putting a bit more stress on the radiator so I'd say it'll be closer to 12-12. so 36-48. Your GPU won't load in the 30's there is just no way. your vcore is fairly high for basic water, i certainly wouldn't go any higher.

PS - do I need to drain the system for a CPU block remount? Or is it ok to do it full of water and just be careful?

TY!

Ok guys. I did some minor modification of the loop last night by:

1. Remounted FuZion to improve CPU temps. Enclosed is a pic of the ceramique on the FuZion and the Q6600 after I pulled it off. perhaps a tad on the heavy side, but a good spread. Well, maybe a tad more than a tad heavy hehe :)

2. Moved the res to on of the 5.25 bays so it wasnt picking up heat off of the PSU. I touched the bottom of the res while it was running in its original spot, and it was indeed hot. In the process I moved the pump to a slight different area which I felt was a little bit better as far as getting air out of it.

3. Changed the fan direction to suck fresh air in from the top of the case and through the PA 120.3. I also switched the 2 existing case fans to exhaust, and added an extra 120mm exhaust fan on the floor of the case.

4. While I was in there, I did a tad bit of wire management. Nothing big, but since I am replacing the fans on the rad anyhow I am waiting to sleeve everything and make it neat and tidy. I can always go back and do more later :)

After all of this work, my temps are as follows.

CPU idle: 38/37/35/34 (was 44/44/42/42)
CPU load: 60/60/58/58 (was 68/68/63/63) load applied with P95 small FFT

GPU idle: 35 (was 40)
GPU load; 38 (was 45) load applied with 20X loop of 3D01 Nature.

Definitely an improvement, but IMHO I think that the CPU temps still need some work. The thing that I feel helped the most with temps was redirecting the fans to bring fresh air in, as opposed to exhaust hot air out.

I have a PA 120.3 fan shroud as well as 8X Yate Loon 120mm D12SH-12 fans from Petras (top performers according to the XS fan guide) and will replace my cruddy Antec tricools and add the shroud which will hopefully help further.

I also plan on an additional remount of the CPU either tonight or tomorrow, but what else can I do to help improve those CPU temps? Im still more than 30C below TJmax, but I still want to get better temps.

PS - on the agenda tonight is a voltmod on the GTS G92 and then pushing that sucker to see what I can max 24/7 it at :D

Thanks again guys and any additional input always appreciated!!!

holding your ambients at 24C, your getting those temps on load.

60/60/58/58 looks fairly good to me at 24C ambients. Unless your getting your ambients wrong.

Do you know how to do a thermometer test?

Dayam im asking 3 people to do this right now.

Look on the other previous threads on h2o cooling at my post on the thermo test. Report back the 3 things i need to confirm this is set in your system.

24C is indeed my ambient. (75F in my house right now)

Yes I know about the thermometer test, Woodbutcher PMd me about it and I will get it done.

But....60/60/58/58 looks good to you for load temps on a Q6600 with my setup?

You're at a pretty high vcore, so it seems right to me.

Considering your vcore, those are good temps compared to my setup with an apogee gtx and mcr220. Nearly identical temperatures as you on my x3210 at 3.6ghz 1.375v (nearly .1v lower, HUGE difference in thermal load). Plus you have a graphics card in your loop.

I wouldn't bother remounting the cpu block. Your temperatures are really close to each other which indicates a good mount.

Hmmm...so a 23C spike in temp between idle/load is acceptable?

I thought that was QUITE high!

Pretty high Vcore? LOL....well I guess everything is comparatve. Ive had this chip at nearly 2.1v before :D

Are you mad? I haven't used 2v on a chip since my AXP Barton with dry ice cooling. I'm worried that the 1.7v I'm going to use on my A64 sandie will kill it with -20C chilled alcohol.

Hehe :D

Well, yes I am a tad on the crazy side....but keep in mind this was also under LN2 on a suicide run :)

Chip is still runnin 100% fine :)

Well thermal load increases by the square of the voltage increase. So .1v higher is a big change.

And you are crazy to do 2.1v, that's just asking for an instant failure.

Perhaps Im crazy yes.

Perhaps I could have instant failure...sure...it could happen.

Perhaps I could also get a WR overclock too :p
