Yes, apply the paste to both sides of the shim. The hardest part will be keeping the shim in place while you tighten it down.

I'll try again when I'm back in town in a week. Below is a pic of what I got followed by a pic of what I ordered...

The mounting holes for the 7950 are the inner ones. Unfortunately they aren't deep or wide enough for the screws to be flush, so they bend outwards when the H60 block is screwed down onto the bracket. I have to loosen the H60 so the mounting screws can be straight just to fit into the card... the seating issues might come from there...? If you look closely inside the square, I had to sand down that nub on the center left for it to fit over the gpu core. Very annoying considering I didn't have any tools to do so... I had to make due with a pair of pliers that had teeth.

Yeah... Dwood changed the bracket mount from full fan to half fan late last year. Unless you specifically order "full" fan bracket, you'll receive "half" one.

And just to let you know, you're not alone dealing with not so stellar bracket finish quality. I'm being nice to Dwood here, but his bracket would not work for me either without fixing machining defects. Just like you I had to file down machining marks on the inside of the GPU bracket, otherwise it would not fit over GPU. Just as in your case my GPU screws would not sit flush so if I tightened the waterblock screws all the way, the GPU screws would bend the bracket enough not to fit through the PCB holes. I had to drill the GPU holes a little bit to make sure they're flush.

I spent better portion of the day on the project but in the end it worked. In my experience nearly instantaneous jump to 70C is normal. I'm not sure if it takes 3 seconds for me, but I definitely reach 70+ degrees in under 10 seconds, but after that it basically flat-lines and holds steady at ~75C with 800rpm fans going. So that's probably normal, although 3 seconds seem a little too fast. Like the previous posters have said, make sure you're using a copper shim, otherwise it will not work. And make sure you spread the thermal paste over entire GPU die, don't do the drop/line method, take a razor blade or credit card and spread the thermal paste over entire GPU die, and then make sure to do the same on the copper shim that's facing the waterblock.

Wow this sounds like a nightmare.

#1, website is not accurate on what you're actually buying
#2, a simple bracket requires major modification... I assumed this bracket was made for people who didn't have the tools to do it themselves. I for one don't have the skill, tools, or desire to drill into my $300 graphics card to fit a 50 cent bracket
#3, I've heard nothing back from Dwood after 3 emails. I was going to file a PP complaint, but **** it. He can keep my $ - I'll just take this as a lesson learned and slap my own wrist.
#4, I think your temps are too high? What GPU do you have? My reference 7950 doesn't hit 70C unless at full load for a couple of minutes, but then the fan kicks in and drops it to ~69C... With the AOI cooler, shouldn't it be closer to 50C?

Thanks for your feedback. It's nice to know I'm not the only one screwed

My mount which was purchased around the same time is perfect and needed no extra work.

58c full load on a 7970 @ 1150/1575.

Is lapping the Antec 620 necessary? NVIDIA thread said the surface has a curve but mine seems to be flat :/

You can't go by eyeballing it, what are you using to actually measure? Use either a machinists edge or a piece of glass to test flatness.

You're right, it does seem a little off. Looks like I'll have to lap it a bit.

Unfortunately I ran into bigger issues. Popped off one of the inductors by the longer VRM:



Fortunately it looks like just a little soldering can get that puppy back on smile.gif Hopefully nothing permanent has been done. I'll be able to do it tomorrow and test it again tomorrow night.

Thanks for your feedback. It's nice to know I'm not the only one screwed

Just to be clear to anyone who read my post and got similar impression, I did NOT drill into my videocard. And I do NOT recommend anyone do it either. The only modifications I had to do was to the bracket itself. I did not have to physically modify my videocard in any way other than removing factory heatsink.

All I had to do was to file down several machining imperfections, and I had to drill out GPU bolt holes in the bracket (NOT the videocard) to make sure they were flush. Overall I was really annoyed that I had to do it, but in the grand scheme of things it wasn't that big of a deal because I had the right tools for the job, but yes, I can see how it would be frustrating to someone without the right tools. Dwood should also update the photo of corsair bracket. Like I said there was discussion late last year when Dwood changed the design without changing photos and at least one more person got upset because he expected full bracket.

My temps are a tad too high for my liking. However, you have to keep in mind that one, I'm running two 800rpm fans on my H100i while most of the people in this thread run 1300+rpm fans. And two, my load temps are synthetic load tests, not in game tests, no game I own stress my GPU to the same degree as synthetics. Synthetics is essentially the worst case torture scenario - I know it's as bad as it's going to get.

Anyway, I just got rosewill fanless PSU two days ago because the fan in my Antec was chirping ever so slightly thus making it the loudest/most annoying component in my computer. And I also got another 900rpm (1000rpm really) scythe fan. So I will be swapping those components sometime this week, hopefully today. This will remove the annoying PSU fan chirping noise, and help with the max GPU temperatures a bit, albeit at a slightly higher noise level, but I think that will be OK. As long as my fans stay under 1000rpm under load and under 700rpm at idle, I'm happy.

Finally got around to installing everything.

Took awhile for the brackets to come in and then it didn't have screws. Had to go trace them down at lowes.

Anyway here is my crossfired 7950s.

Kinda disapointed in performance. My heavily OC'ed 670 would never break 65 with one Noctua fan. Using two on the top card and on on the bottom card, at stock they max at about 70 to 75 (depending on ambient tempature) while bitcoin mining. Around mid 60s while gaming.
