I agree, I have three of the Hybrids running and I don't hear them at all. Just sound of water trickling on startup.

I think it should be fine to attach the heat sinks to the front plate, at least I will try that. The way I saw it, the stock ACX heat sink on 4995 hardly even touches the front plate, its mostly attached to the GPU. Though it has a fan on it. The front plate does get very hot, so I guess it is transferring heat from VRMs and fan cools the plate.

I meant, Iff (Note: iff), the GPU heights were different for 4995 and 4992, then Corsair could not have the same mounting height+plus screws which work for both 4995 and 4992. They would need two sets. But iff.

That leaves only screws being different then. The HG10 has its own thumb-screws, but they mount the water block on to the HG10, not to the board. The HG10 is separately mounted on the board first.

I find this very interesting. I have EVGA 4995 cards. On one of them I used HG10+H80i, no stand offs, it sat well but I don't think I was able to align it, the temps were not good as I mentioned. On another 4995, I used EVGAs Hybrid kit, although EVGA says the kit is not compatible with 4995, but its compatible with other EVGA cards with non-ACX cooling e.g 4992. What I noticed while installing EVGA kit was that when the water block is flush with the GPU, the screws (M2x6mm I think) )which came with 4995 are not long enough to mount it as is. The screws came with springs, I had to remove the springs and then only the screws could reach the block (from the below the board). All installation videos I saw with non-4995 cards show the screws being used with the springs! I think there are only two possibilities: 1. The 4995 screws are shorter than other EVGA cards 2. The GPU surface height is different for 4995 vs others I looked at a videos and screw lengths "appear" to be similar. Which leaves point 2 open. Is that even probable? The gap of 1-2 mm you saw, would be consistent with GPU height being lower on 4992 vs 4995.

I also give up on this bracket. I re-installed the EVGA hybrid kit and it does not even hit 55 on load, 10 minutes on Valley. Where's as the HG10+H80i was hitting 70+. I suppose the fundamental problem is that does not mount directly on the PCB as the EVGA does, so will be mis-aligned unless you get really lucky. Not to mention the bent card.

I do not have experience with this, some 3M double sided tape or super glue won't do? It black and gold alright. Edit: I think it's a bad idea, that thing is heavy and spinning at 1000rpm. And the hybrid shroud does work with 4995, there are no mount points. I think I'll just put an extra fan blowing down on the cards. That should keep the VRM cool I guess.

I should correct myself. I have 4995s, ACX SC+, the fans for them are on the heat sink. That's not usable. For the Hybrid kit, they have given a floating shroud. As per the instructions, if you use a stock card, the blower should be already on the card. I guess it should be on the front plate, I do not know for sure. Either way it's not on the Hybrid shroud. I my case with Hybrid, I will have to mount/stick the fan on the front plate, black coloured plate similar to the back plate. Then put the Hybrid kit shroud on top.

Yes, it's fixed on the front plate, the shroud just hovers over it.

Wow! Something to try then.

So then I am off by degrees at least with HG10+H80i. I am using two Noctua fans in push pull though. The bend I think is a serious problem. I had a tough time slotting it in the PCI slot even though my bend is very slight. I am sure either the card or the PCI slot or the MB is going to get damaged sometime. I managed to install the EVGA hybrid on the 4995. I could use both the front and back plates. I had to just remove the springs from the GPU screws. Temps are similar to HG10+H80i, but that I think is mostly due to thermal paste getting a whack I was trying to adjust the screws. A refit should solve this, now that I know not to use the springs. I might add the fan from the HG10 for now for VRM cooling, it fits within the EVGA Hybrid shroud. Maybe Corsiar should just sell the fan;)

What idle and load temps we should expect with 27deg room temp ? I just tried the EVGA Hybrid, it won't fit with HG10, the square opening is not big enough.

I doubt just higher speed fans will bring it down to mid 50s. I should have the EVGA kit soon, let's see how that fits with HG10.

Are you sure they will go down by 10 degrees after break-in?

The G10 is also not an option for 3-way SLI, as I think its extends to the 3rd slot. Also how does one see the VRM temperature and how will you know it not cooking? I am not sure its a good idea to run without a fan.
