Yea is not a reference model, the alienware x51 came with a lousy graphics card reference gtx555, an i decided to take a risk an bought a non reference Gainward Phantom gtx670 which had a very good cooler, but not good for a small form factor like the alienware X51

And the Phantom came with heatsink you can see it in the picture the silver metal one, and the copper ones are the ones i added but i forgot to take a picture

What comes to fans cooling, I added a 8 by 8 fan that you can see in the pictures is the Blue one, and in the back there is an original PCI fan who was there in the past and pushes air to the graphics card compartment

Anyway my machine is not a very common pc, but this AKA mod did magic to him !! ( I was always running over 85 c in all games, now the must max so far had been 56c 4 hours play max setting on crysis 3, on a warm room average 27 c using a fan of course lol)

Thats great results, congrats.

Can someone please point me to a picture of a fan mounted on top of the VRM heatsinks with only ZIP-TIES, and not Dwoods Bracket? His bracket keeps the fan some milimetres away from the card components, I read that some users used zip-ties, I am afraid of damaging a component or melting the fan or something.

Thank you. smile.gif

Wuhhhhh - is that all one loop? Are the Kuhler's cheapo waterblocks or is there a pump in one/both of them? Build log? Awesome? smile.gif

Looks nice. No VRM fans?

I got 2 H70's for the 2 GTX 670s I've got and found out the holes to secure the bracket will not fit. Has anybody run into this problem? Or has anybody used the H70's to give me a run through? Some pictures of the process to make the brackets fit would be great!

Yo. Check Post #3808 it should give you an idea of how to proceed if your using your own bracket supplied with your cooler.
post #4098 of 8621
Done the mod, partially at least, because its not finished. I put my Asetek 760GC CPU+GPU WC kit cooling only the 2500k @ 4.3Ghz (while I wait for my other 670 to arrive) and a Asetek 740GF GPu WC kit cooling my 670. I put some heatsincs on the gpu ram, mosfets already had it. In the photos you can see the PCB lenght difference between my old 570´s and this new 670, they must have been 1/3 bigger. I am not very good with cable management but when I put the other 670 I will try to do better wink.gif
My results are pretty impressive, my gpu idle temp is 25C (room is at 17C) and my CPU at 35C. On load GPU gets to 43 smf CPU to 53 but My GPU fan dosent rise from 30% so its very quiet while gaming/benchmarking. My old top and bottom cards in SLI would get to 35 and 28 in IDLE mode and 97 and 72 degrees while gaming so I am very happy with temps. Also like the fact that I now get 9000P points in 3DMark11 with only one card, when I used to get 1000P with the 2 570´s.
The only thing I certanly o not like is the noise while in idle mode. I have Noctuas NF-F12 PWM on the Asetek 740GF connected to the CPU_1 and CPU_2 MB headers and I have a Gentle Typhoon AP-15 on the 740GF, connected to the 3 pin header on the watercooling kit (it´s suposed to control the fan automatically, confirmed bt Asetek support). Also mounted with zip ties a 92mm arctic cooling PWM connected to the VGA fan header, with the respective adapter of course, along with the kit pump. I connected the 760GC 3 pin pump connector to the 3 pin PWR_1 MB header and the sensor reports it at 1450 rpm. The CPU fan RPM sensor is always at 750 RPMs but I hear a fan spining faster when I start the PRIME 95 stress test.
What am I doing wrong? Should I ditch the noctuas and buy another 2 gentle typhoons, connecting them to the 760GC 3 pin headers which I am not using? Should I connect the fans to different headers or someting? I really want to reduce the noise, that was my purpose from the beginning...

And I want to thanks for all the help and ideas you´ve been giving me. smile.gif

The CPU PWM reading you're getting is from the pump, not the fan. I'm not sure how those units work (lower models like mine don't control the fan speed just keep 100%), but I would assume the pump is controlling the CPU's radiator fan speed. If this is the case, the CPU fan/Gentle Typhoon is probably spinning pretty fast and could be the source of your noise. What speed/model of GT is it? You might consider putting a resistor (your Noctua's should've come with them) on the Gentle Typhoon to decrease it's maximum speed - some of them can get really loud.

If it's not the GT then I would grab a toilet roll/paper towel roll tube or something and check to see where the noise is coming from. You own really quiet fans (assuming the GT is a lower speed one), so if the NF-F12s aren't spinning faster than 30% I wouldn't expect much of your noise to be fan noise, even if the GT if spinning at 100% (unless, of course, it's not the 800 or 1400 rpm version).

In my system the loudest components are the pumps. This is probably your situation as well. I was also disappointed to find that my system was louder at idle after the mod than before, but I guess what they say is true - unless you have the time/money to buy a nice pump and decouple and soft-mount and maybe even dampen it, air is quieter than water.

Thanks a lot for your thoughts.
My gentle typhoon is the ap-15, a 1850rpm model. It's mounted on the 740gf, the GPU only kit. I ve put my ears real close to each component and got to the conclusion that that fan is indeed the quieter one, but even so I believe I will use the low voltage adapter. The only thing is that adapter is a 4 pin and the Gentle Typhoon is 3 pin, I think it won't work, but I understand what you mean. Meanwhile I disconnected 2 standard fans that came with my CM storm scout case and noise is a bit quieter. Regarding pump noise I didn't know that it was so resembled with typical fan noise, so I believe you are correct. Also tried controlling the Noctua's fans with Asus probe or speed fan but it doesn't do anything. Maybe I will end up removing one of the Noctua's. Connected the 3 pin power connection of the Asetek 760GC to the P8Z68 Pro motherboards 3pin pwr_1 fan header (not voltage controlled) and the sensor reports it ar 1450 rpm fixed, would it help if I connect it to the Chassis_1 fan header (voltage controled by bios) ?
I will keep trying to improve the setup. Now I am waiting for the other gtx 670 and my 27 inch 1400p monitor, if you have other ideas I would be thankful ;-)
