GTX 460 reference design + MCW60: Work Completed

post #1 of 28
Thread Starter 
Here is a preliminary report for my video card change. I am not done yet, work in progress



Above is what greets you when you remove the cooler. As you can see the thermal paste used on the GPU does not really look like a good one. So even if you don't WC still remove it and replace the TIM with a better one.

This is the 768MB version of the card and the small circles show you where the memory modules will be in 1GB version.

I was going to order a MOSFET heatsink but thanks to Galaxy I didn't need to. The big blue circle shows the MOSFET heatsink that is used by Galaxy. Thank you Galaxy for not making a big block for cooling everything



For removing the cooler you only need to remove the left 4 screws shown in circles in the photo. The other 2 circles to the right are the screws that are for MOSFET cooler which you don't want to play with.



You can see the 2 heat pipe cooler above.



And this is how the cooler looks from front.

I had G80 and GT200 adapter kit for my MCW60. One option is to buy the new bracket adapter which will cost you $15:

http://www.frozencpu.com/products/12...ia_GTX460.html

For the other option follow up. Unfortunately there is no way you can use G80 on this GTX 460. For GT200 adapter you will need to drill holes. Here are the diagrams needed to convert the GT200 bracket to a GT400 bracket.

GT200 bracket.


GTx460 Bracket


Update:

I finally had time to finish this. Below you can see the picture of the bracket after the drill work



My holes were a perfect fit on the card but still you have to be careful when drilling those holes. You don't want a very tight fit on the card.

As long as you follow this guide you should be fine fitting MCW60 on this card. Btw temperature are now around 25-40 C although the whole heatspreader is not covered by MCW60. So you shouldn't have any doubts on this and run out buy MCW80.

Enjoy

P.S: This is a guide for only MCW60 on GTX 460 regardless if it is reference or not as the holes are the same. If you are looking for a full block guide pass on this one.

Gt400? You mean gf104?

Interesting I want to move my galaxy cards (same model) to watercooling. It looks like the standard reference design to me from your photo (compare with http://www.koolance.com/technical/vi..._reference.jpg)

However performance pc's claim it's not a reference design. If it is, then xspc full block is a great deal. If not then I'll have to decide whether I spend more for a full coverage block.

<edit> After looking at the installation manual for the xspc kit I see that it was designed to cover the vrms with an extension plate. As this has a heatsink I think I should be fine using the xspc block to cool the gpu + memory and leaving the vrms cooled by the heatsink as it is now. It might even be possible to use the extension plate depending on the height of the components between the vrms and the memory. Certainly the caps could be easily moved to the other side of the board if needed.

I could go the same route as you and just use the mcw60, but it seems to be in the same ballpark as the xspc full block ($55 vs $60)

I have posted the block diagram for GTX460. This one follows it.

Like I said the mosfet are already passive cooled. The memory modules doesn't really need cooling. The original cooler only cover the GPU not the memory as well.

haha, yea, I know what you posted, and it is right, I was just making fun of you because there is no such thing as a gt400 it's the GF1xx

I would highly recommend getting some ram syncs, they do not NEED cooling, but when you start OCing they will start to get hot and on graphics cards that will cause you to get artifacts sooner. so ram syncs = higher OC.

They don't make an adapter plate for the MCW60 for GF104? From what I have read, the MCW80 retains the same physical footprint as the MCW60, and brackets would 'likely' fit between the 2 models. So, thinking the correct bracket would be a good way to go, but if you want to save yourself the ~$10/bracket, go for it...hope it works.

Kevin I was not responding to you. It was for stren.

But since you are insisting on with your joke here is your answer. The naming for the bracket for this card is just GTX460. However, there actually is a GT400 bracket, that's the naming swiftech uses. You can see for yourself below.

@ Rubix: Yes they are selling the bracket I posted in the first post. I am not wasting $8 + $7 shipping for that one bracket (frozencpu). The setup is done now it worked out pretty good

Gotcha...I was just wondering if it was a cost issue, or bracket availability. I currently run 2x MCW60's, so glad to see they are at least supported to this point.

Well it is discontinued with the release of MCW80 but the brackets can be used with one another. However MCW80 footprint is large enough to cover the GTX460 GPU unlike MCW60. To me it doesnt really matter as long as it covers the important part (the center area).
