Antec Kuhler/GTX 480 Closed Loop Water Cooling Mod *~GUIDE~*

Hi guys, this is my little guide for how I installed an Antec Kuler on my new/refurbed EVGA GTX 480. I included pictures showing installation using both the cable tie method and the more secure mounting bracket method. I got my bracket from user "Dwood" over at OCN. After conversion from USD to GBP, the total cost of the bracket (including postage) was around 8 quid and it took about 2 weeks to arrive. Feel free to ask any questions :).

Things you'll need
GTX 480 (other compatible card)
12 or so cable ties or an appropriate bracket
A philips head screw driver
Scissors
Some Thermal Interface Material (and something to clean the old stuff off with)

The Guide
First step is to pop the top half of the shroud off. You don't need to remove any screws for this part, you just need to pop the plastic tabs on either side (4 tabs on one side, 3 on the other):

Once that's done you'll be left with something that looks like this:

The next step is to remove the following 4 screws.:
Note: These are the only 4 screws you will need to remove during this mod.

You'll be left with something like this:

Clean off the old TIM to get the Kuler and card ready for mounting:

(IF YOU'RE USING ONE OF DWOODS BRACKETS, SCROLL DOWN A LITTLE :p)
Next, take 4 of your cable ties and slide them through each other to form a shape like this (make sure to leave room enough for you to be able to slide it round the tabs on the Kuhler):

Slide the square cable tie shape over the Kuhler and tighten them a little:

Next, slide 4 more cable ties through the 'corners' of the shape and tighten around the ring:

Slide the 4 ties through the holes around the GPU (don't forget to use some thermal paste):

Take 4 more cable ties and slide them over the last 4, and tighten to 'lock' the cooler in place:

Grab a pair of scissors and snip everything down for a nice clean look, and the job's done :):

(CONTINUE HERE IF YOU'RE USING A BRACKET TO INSTALL THE KUHLER)
First off, grab your bracket:

Arrange everything so that they sit in this order (top to bottom):
Bolt -> Bracket -> Kuhler -> PCB -> Washers -> Screw

Tighten the bolts just enough so they stay on, then stick the Kuhler through and twist just like you would with the stock bracket. Once it's in, screw it tight enough that the Kuler doesn't move below the bracket, but no so much that you bend the PCB:

Stick some decent fans on the Kuhler, pop everything back in the case and reap the benefits of your quiet, cool running GTX 480 :D:

With a 900MHz overclock, my temps after Kumbuster (running for 40mins) maxed out at 58 degrees (confirmed by CPUID HardwareMonitor and MSI Afterburner, though Kumbuster itself registered max temp as 60 degrees). Playing BF3 on Ultra Preset (4x AA) @ 1080P for half an hour on Grandbazar (64 man conquest), temps maxed at 70 degrees and frames were avg 52FPS. At no point did it get any louder than at idle :D.

Nice.

Are the memory chips, vrm's, etc still cooled by the stock bracket then? I would have thought heatsinks and some direct air flow is generally recommended.
 
Very nice :D

Cheers :D

@MichaelM
You're right. The stock bracket is handling the VRM and memory, and from touching it while running BF3, I'd say it's doing it's job well :cool:.
I've left the stock fan on to keep some air moving over the bracket and it works fine :).

If you wanted to keep the stock shroud on (and the directed air flow & aesthetics it provides) you could if you used the cable tie method, but because of the bracket I've used I'd have to brake off the middle 4 plastics pieces shown in the pic below:

I just did this to a 470 good edition. I just wondered if there is any way of controlling the 120mm fan speed from the gfx card?
 
Surely its getting to the point where evga/asus should start looking at doing this retail? Seems like a cracking idea with these all in one water systems
 
would this work with literally any videocard?

yep its been done with many different ones including a 4870 !

I did it recently with a GTX 580 and the OCUK Extreme see here GTX 580 cooled by OcUK H²Flo Extreme Liquid Dual Fan CPU Cooler - Mod

Its a bit harder with this as the pump block is square.

You could use the plug/wire from the 470 and either solder it to the 120mm fan wire or use a connector block.

On mine I have both the pump and 120mm fan controlled by a fan controller as it then gives me the RPM and control over noise better.
 
double thickness one though ?

first off it depends what you call "double thick"... corsair list the H80 as being double thick, but at 38mm I call that marginally above average

even if it was, double thick rads don't give double the cooling, unless teamed up with monster fans, which would then be quite noisy and somewhat defeat the purpose of watercooling

as a general rule, a 120.1 rad will cool 110 watts with 1600rpm fans, a 60mm (e.g. actually double thick) all copper rad will do 123watts at 1200rpm, 150ish at 1600rpm and over 250ish at 3000rpm

a decent CPU + GTX 580 will be close to if not over 400watts when overclocked, so you'd have to be running something like 5000rpm for a 120.1 rad to cope :D

(radiators do get more efficient the hotter the water gets over ambient so it might be marginally cooler than an air cooler at the same noise level, but it is not going to be in any way comparable to a custom loop kit with say a 120.3 rad which would probably not cost a great deal more if done with a universal VGA block)

its not really a factual term I was using anyway but an adjective really. The OCUK Extreme radiator is double the thickness of the Antec 620.

It was just the best way to describe it. I understand what you mean about the cooling etc but the description for the 760GC says its designed for a 570 or 580 so why would they sell something with rubbish cooling ?

Although its not on sale in the UK and I have not seen a review yet ............... ;)
 
it probably does offer a small advantage over "stock" air cooling, e.g. Intel reference cooler and Nvidia reference cooler

but as is typical with these sealed unit water coolers, they won't compare well with aftermarket air cooling (which will in all likelihood be a lot cheaper and quieter) or with a custom loop (which will be a little more expensive but will be a lot lot better), and will start to struggle when overclocked - e.g. you will probably get a good air cooling OC, but no where near a decent water OC

some people are put off by building a custom loop because water + computer = scary, so these sealed units offer a small part of the benefit of water and you are paying someone else to build it for you (unless you get lucky on a kit like yours that they seem to no longer sell)

Can someone give the link to directly order these? Wonder if anyone has done it with a 680....

EDIT: Don't worry found it (and he did the mod for his 680...interesting....)
