Here is a few pics with narration (oc.net didnt have narration) ill try to demonstate how my method improves cooling on those parts.

Here is the naked pcb, looking down on it without its heatsink. There is all sorts of crap on that pcb, none of which im going to try to pretend i know, cause i dont. The important part here is there are important sections on that pcb, namely that section with the black metal part surrounding it and again the other part....over there. All these important parts are mostly exposed without any type of heatsink attached to them save that black metal part on the pcb.
Here is a picture of the heat sink, its massive.

Important part, the heatsink only has TIM on one spot, nowhere else does heatsink come incontact with the pcb/other parts. Only the grahics chip and heatsink touch, held together by four screws.

The two fans line up with the two large finned sections and need to blow air into those finned section, once past the air gets to blow on the pcb/stuff on pcb. The air is also hotter as its picked up the heat going through the heatsink...could be as much as 78c...the hottest ive seen my Matrix get benchmarking.

You can see right through to the pcb here, ive removed the heatsink and was just dryfitting the shroud. There is no resistance between the fans and the pcb, those are big fans, 90mm each, thats alot of air movement. Right now, this alone allows for better cooling as the air is unheated by the heatsink and there is no heatsink to restrict the air flow.
Now just to gloat lol,,,kidding

This is my Zotac 560ti heatsink. The Matrix was my second mod, this is how i know the zipstraps are awsome for this mod. Not only is it totally stupid easy, i couldnt slide that pump around if i hit it with a hammer. Like i said it may as well be screwed. The matrix Had some tinny play, almost unmoveable but if you really tried you could get it to just budge. I figured once the tim cured abit, stiffened up some it would be rock solid.

Dry fitting the pump. I wanted to make sure the hoses came off the pcb NOT facing the motherboard. As it turns out i had to wedge one coolant line between the Motherboard and whatever room was left after snapping the Matrix in to its slot...got lucky there
🙂I never modded the Corsair H70. The coolant lines were sleeved. Im weird that way, everything has to be sleeved. I didnt want to cut the lines to do it so i just stitched it on the back and i turn the sleeving so the stitches are seen.

Well worth the time IMO

Thats a close up of the H70 pump pressed against the graphics chip...i chose the card method to spread the TIM.
The fans and shroud are attaced to the rest of the card by 4 screws, two screws on each end that screw into the heatsink, no heatsink no way to keep the shroud attached to the pcb. The shroud now attaches to the pcb using a bracket i made from a black plastic coat hanger, i wanted somthing that would not short out the pcb. I cut it down with a haxfile blade i had lying around.
Just clips to the pcb

here is a benchmark. I was agressive with my overclocks. The first was 965mhz, then 1000mzh. Took three attemps to keep 1000mhz stable.

I really need to keep the "Matrix" lite, that was unconditional, needed to keep the light.

The H70 rad is square now, i was still dry fitting the card and had not screwed the rad down completely.
Quick shot of my Zotac 560ti, fantastic card btw, great overclocker after this mod. Their card had the same type heatsink design with only the graphics chip and heatsink touching. I had lots of people asking about worse cooling with this mod too. Note here too that the fan for the 560ti is completely removed, nothing cooled the pbc here. I ran this card like snot, really beat the crap out of it and i never had a single issue with this card. Works to this day perfectly and still overclocks poorly when its stock heatsink was replaced.

Thanks for letting me post some pics. Very fun card to play with. Cant wait to really beat this card up benchmarking l
