We pull apart this complex GTX295 card to squeeze out better temperatures!

The GTX295 has been NVIDIA's latest card, taking the performance pole position and squashing ATI's offerings underneath its black shell. But how often have you wondered what exactly was inside one of these cards? Is it just a heatsink, or is there anything else in here working a little magic and if so - can we improve it?

While we're reasonably sure it's not going to be magic, we do know that there's going to be some cooling in here that can get tweaked, and that's where we step in. Pulling apart the 4870X2 was a relatively simple affair, something that most can manage without too much worry - this card is anything but.

This extra complexity comes from the GTX295's design, in that it's two separate PCB's sandwiched together, rather than two cores on the one. Both are oriented to face each other, and hence share the same heatsink, needing a very clever cooling solution and a lot of screws.

Knowing that most manufacturers will make their cards with an excessive amount of thermal paste, we narrowed our improvement choice down to just that - clean off the original goop, and replace it with some of our own. When we first had a look at the GTX295, we recorded an idle temp of 55 degrees and a load of 78, but will our improvements work? Keep reading to see what we do to the test subject GIGABYTE GTX295 pictured below.

Having an irritating bastard like me pipe up about the Alienware photos must've motivated the cameraman to do better :D

The GPU die size on the gt200 cores even at 55nm is so large, it makes me appreciate ATI's rv770 die much more.

Wow, so brave. I have a 9800GX2 and I would NEVER do this.

Reason? It works fine now.

But nice job guys. Really interesting to see how they actually fit the 2 pcbs together like that.

Snake: There are a lot of reasons we love getting into the guts of stuff. For one thing, it's fun, and for another, we figure (correctly, it seems) that this is something we are able to do that a lot of people would not feel at all comfortable doing, but may well be very curious about.

The other reason, and this only became apparent after we took the thing apart, was that factory applied thermal paste is damn sloppy! Just adding better paste, and applying it well, kept card temps down a few degrees. It may not sound like much, but in an overclocked, enthusiast-grade system, we think every degree counts.

V1RUS: Check out the Atomic Feedback section of the forum - always glad to hear suggestions and comment there :)

Well done! I must admit, it's always a first step of mine (after making sure it works) to disassemble and reapply thermal compound where possible. Just makes the project feel a lot more personal, and the extra few degrees are often worth it

Impressive piece of tech. Be fascinating to see how the factory assembles these things. Any chance of some sneak peeks from the Jolly Green Giant?

Oh, the second and third pics are the same too - the 3rd pic should be the one showing the 13 screws on top of the card.
PS. Can't edit the post? Am I missing something?

Great guide, i would have run into strife without it. Interestingly, on my reference model card (inno), temps dropped 10 deg C across the board after a disassembly, dust and new thermal compound. quite a dramatic change and worth the time...
