post #1171 of 3006
My bracket from Dwood took over 3 weeks to arrive, and when it did, I didn't get what I paid for. It was missing 90% of the fan mount part, required sanding just to fit, and wasn't machined to the exact precision required by the provided mounting screws. Overall I'm very disappointed. I understand he's busy, but I wish I had known this before ordering. If I had, I wouldn't have gone through the trouble of ordering 2 H80i's (first defective), a 92mm fan, vrm heatsinks, etc. A round Antec would've been the way to go since they only require zip ties.

Anyway, i tried installing the bracket anyway. Insta-crashes under any kind of load. GPU-Z reports 70C on the core in about 3 seconds of load, and idk why or what's wrong. I have the H60 rev2 (using that instead of h80i because it actually doesn't fit in my case) plugged into a chassis fan header and the fan plugged into another chassis fan header. This is on a 7950 with a reference 7970 pcb.

The shim is required for the 7950/70's right? Can anyone recommend good thermal tape for the chips surrounding the core? I really want to make this work.

My bracket just came in as well and was flawless. Do you have a picture of it?

Insta-crash under load means that it isn't seated correctly, period. A shim is NEEDED for 79x0 series cards, and the die on a GPU is huge so it needs a lot more TIM then a CPU would. My first mount hit 90c instantly under load and when I pulled it apart the GPU was bare on all 4 corners since the TIM didn't spread enough to cover the whole thing with the center dot method. I recommend the "old school" way of applying TIM since before CPUs had IHS's - using a brand new, clean razor blade to spread a thin layer of paste instead of hoping the mount pressure will spread it over the huge die.

If its not instant crashing and just running really hot, then make sure the fan header you are using for the pump is not using software to control it, set it to 100% in the BIOS/motherboard software.

Why does the pump need to be at 100%? I was planning to use PWM control for mine, using Speedfan, and base it on GPU temp (along with the rad fans as well). Is that a bad idea with these closed loops?

Not necessarily 100%, but they at least need to be setup properly. Some controllers will default to way too low percentages like 30%, which may be fine for a case fan but may not even be enough to push the coolant through the tiny AIO pumps.

The pumps are so quiet anyway I don't see a reason to not leave it at 100% IMO.

Good to know, thanks! My controller will allow for both configurations, so I'll be sure to test every variation.

The TIM (MX-4) was spread out (I added more to areas that the initial press-down didn't cover) and the bios had everything at 100% (even though I am unsure which headers run with full voltage and which don't)... 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.


This is what I ordered. The above might still work, but it's definitely not what I thought I was buying.

Hmmm, the screws are very small so if the mount got tweaked or bent any during shipping then it will make the screws not run straight. I would set both the mount and the shim on a piece of glass or a mechanics straight edge to verify that both are perfectly straight. Does the block move any when installed? I installed the nuts by hand, then took a mini screw driver and torqued them down just a tiny bit until the block wouldn't rotate as easily. Too tight and it will bow the PCB and not boot (or worse), and too loose and the temps will be poor.

Stupid question, but you put TIM on both sides of the shim right?

yeah I'll take pics of the mount in a week unfortunately frown.gif I'm itching to get home and retry lol.

If this works well and it turns out it was due to my error, then I'll do it again in Crossfire but with an Antec so I don't need to wait on a bracket.

Can anyone recommend thermal tape? How thick is stock tape?

So, guys, I just had an idea of how to install the square style AIO coolers like some of the Corsair without the custom brackets. Since the block is square. Why not try to create a square with multiple zip ties? When I get paid back from my friend, I'll be purchasing one of the coolers for my first attempt, and testing out this idea.

I managed to steal a great deal for the HD 7970!!! Met up with someone who sold this thing to me for $220!!!
He was initially asking for $150 and I felt bad for him so I give him extra money. Never the less, a great deal.

Anyways I want to do the watercooling mod for the HD 7970.
I have done the mod with Nvidia cards before but never AMD.
After dissembling the card, i found out that I needed a copper shim for the mod to work properly.
So my question is will the extra piece of metal sandwich between the cooler and GPU effect the temperature?
How am I suppose to apply the thermal compound, apply to both sides?
