  1. Hey Everyone, In early 2020 I bought myself a Corsair 1000D for a planned build. As part of my plans I needed the optional 8x top fan tray. It was out of stock when I bought the case, so I added myself to the Corsair Shops notification system and waited.... and waited... and then waited some more. In the mean time I built myself a temporary system because I was unable to do what I had planned with the top bracket. By September 2020, with my build 8 months delayed, I contacted Corsair support. They apologized for the wait, and offered to send me a bracket for free as a one time gesture of goodwill. I told them that it really wasn't necessary, I'd be happy to pay for it if I could only get it, but said I would accept it if that was the only way to get it. The ticket was closed, time went by and I never got either shipping confirmation or a top tray in the mail. Then in October I got a notification that the Corsair store had them in stock again. I assumed I was never going to get the one from support, so I logged on to buy one, but apparently I was too slow. They were out of stock again. Since then I've been back on the in stock notification, with my temporary build still sitting under my desk, checking in every now and then, but the part is seemingly permanently out of stock. It has now been 22 months, almost two years, of me waiting to finish my build I started planning in 2019. I'm practically getting ready to upgrade the components I bought again before being able to finish. At first I assumed it was just a pandemic related supply chain problem, and they would be back soon, and it keeps just not happening. So I ask, is this 8x fan bracket ever going to come back in stock again? Or should I just move on? I feel like I've already held out hope longer than most people would, and it is quite frankly starting to get ridiculous. Appreciate any thoughts.
  2. Yep, and inofficially you can easily fit a 420mm (3x140) radiator up top as well, as long as you don't mind losing your top drive bay and bending the top two tabs in the drive cage. Just don't go with a much radiator thicker than 45mm, or once you add a typical 25mm fan, it will likely interfere with motherboard components. 60mm thick definitely won't work unless you plan on going fanless :p 120mm radiators might be able to be thicker, because they ahve more clearance on the bottom for various caps and other motherboard components to fit, but it's going to be on a case by case basis.
  3. So... Posts from Corsair reps have been conspicuoulsy absent for a while now. Are we still expecting a fix?
  4. He's not using the n980. The other bracket is easier to get to make good contact so temps are better, even at low fan speeds. That being said, I have dual noctua 140mm industrial ippc-2000 fans in push-pull on each of my h90's connected to my 980ti's I have them PWM controlled off the video card, and at stock (factory OC) speeds and the default fan profile the fans barely even turn on at typical gaming loads. Highest I've seen has been 18%, which corresponds to 360rpm This is technically below the fans minimum speed, but I think the video card accomplishes this by pulsing them on and off. Otherwise I'm not sure how it works. Either way, its silent (apart from that one H90 that has a groaning pump, I really need to RMA before something bad happens.
  5. You can find out by connecting it to a power supply and connect one of the ground wires on the PSU to the fans PWM wire. It will then spin at its lowest speed.
  6. I've posted the below many times. Only solution I can think of. Really isn't that difficult, just requires a soldering iron, some solder and some wires you can cut apart and use.
  7. I did both of these by making a custom wire harness. I'd repost it but I am currently travelling in Brazil and only have my phone. I posted a diagram and a picture of the finished result, several pages ago, I'm sure you can find it. The reason the hg10 fan is noisy is because the pwm specification allows fan makers to specify a minimum fan speed, below which lowering the fan percent just keeps the fan running at that same speed. IMHO the fan chosen for the hg10 has a much too high minimum fan speed, especially since it only needs to cool the VRM's and VRAM. I solved this by modding it to run on 5v. Works like a charm, is inaudibly quiet and never overheats.
  8. Nah. HBM Certainly is the future, but in an incremental way, nothing groundbreaking. All it does is let next gen GPUs breathe a little more, but the truth is that currently GPU's are not memory bandwidth limited, so the bottleneck will still be the GPU, not the VRAM. Where I think Pascal will be interesting is that it will be he first die shrink in forever. They have been stuck at 28nm since the Radeon 7970 was launched in 2012, a bloody eternity in these things. If you think of it this way, the 680, 690, 780, Titan, 780ti, Titan Black, Titan Z, 980, 980ti and Titan X are all on the same 28nm process. This is completely unprecedented (at the same time it is pretty impressive how much of an improvement they were able to get going from 680 to Titan X on the same process) Pascal will reportedly skip a generation and go straight for 16nm, which will lowethe power use and heat output, and allow for much more powerful designs. One could argue that this will be the biggest advance for Nvidia since the 680... They probably won't go full out though, unless AMD also.launches something competitive. That way they can pace themselves and leave easy performance gains for the next generation after Pascal, or Pascal2 or whatever you call it, just like how we got a Maxwell refresh. A big Pascal should be interesting indeed.
  9. That is true. I thought of doing this, but I am using these with the EVGA backplate on them, and I am concerned a bigger M3 screw won't fit cleanly in the counter-bored hole on the backplate. I might try something though.
  10. Yeah, I noticed this before even installing the HG10's into my system. I addressed this by volt modding the blower fans, using a custom wire harness, which also allows the GPU PWM signal to control the 140mm fans on the H90. Click for Bigger: My blower fans are now inaudible. At 0% PWM signal they spin very very slowly at 5V, and when the PWM signal increases, so does the blower fan speed. I figured I could get away with this, as the fans seem designed to cool a full GPU, and in this configuration they are only cooling the RAM and VRM's, so a much slower speed is all that is needed. The PWM signal also controls the 140mm fans in push/pull on the H90, meaning I can still use MSI Afterburner, or EVGA precision X or other tools like that to manage fan profiles. I initially suspected the noise was coming from some fan in my system, as it sounds like a fan hum from the outside of the case, but when I systemically went through with ASUS Fan Xpert and tested each fan header, it turned out that the noise went away when I messed with CaseFan1, which is where I plugged in the H90 pump for my top GPU. My theory now is that either there is vibration due to the way EVGA connects the PCI bracket to the board, that leaves the hole unpopulated once the HG10 is installed, OR I have a bad H90, which I may have to RMA. I ahve not had the time to open the case and poke around yet. When I do, I will find out more. I didn't notice it when I was doing my install at my workbench in the basement, but I have pretty loud flourescent bulbs above my workbench which probably covered up the noise. To illustrate the screw issue, on the EVGA ACX2.0+ 980ti models there is a screw (closes one in the corner in this picture) which you have to remove in order to take off the black heatspreader EVGA installs for the RAM and VRM's. The heatspreader needs to come off in order to fit the HG10. The problem is that the PCI bracket has a loop that the screw pokes through to hold it in place and the hole in the heatspreader is threaded. The HG10 doesn't have any screw mount in this location. So, once the HG10 is installed, there is a hole in the board, that lines up with the hole that attaches the board to the PCI bracket, but there is no threaded backing, so you can't tighten a screw in there without a nut. The PCI bracket provides a large amount of the boards stability when installed in the PCIe slot, so with a pump vibrating and the bracket only installed on the bottom, it is very possible this could result in my noise issues. I need to figure out what size the screws are so I can get a nut, and tighten it down. The Manual calls these screws M3 screws, but they are smaller than the M3 screws that are normally used in computers, for such things as screwing in 2.5" drives. Those screws are M3x0.50. Either these video card screws are the smaller threaded M3x0.35 size, or they are not M3 screws at all. Unfortunately I lack the tooling to properly measure the screw threads. Technobeard / CorsairDustin: Would either of you be willing to share the screw size of the little black mounting screws on the BOM of the HG10? This would be very helpful for me to find a matching nut. Thanks, Matt
  11. Nope. I'm using mine (installed with the washers as suggested by Corsair_Dustin) I'm not seeing quite as good temps as I had hoped, but certainly better than I did with the stock ACX2.0+ cooler, and they are perfectly silent. During actual game play at stock clocks, the most my GPU fans have spun up to is 17% (and the Noctua fans are dead silent at that speed) and sit at ~60C. The current titles I am playing don't require overclocking, as I have them vsynced at 60hz and am getting no more than 60-70% load, so I just keep them at stock speeds for now. Before they would spin up crazy fast and be very loud. Now I can't hear the computer at all when wearing my headphones, even during extended gaming sessions. I'm sometimes amazed when I take the headphones off, at how quiet the computer is. Now, I am waiting for the official fix, to get the temps I want so that when I need to overclock, I can. My biggest annoyance right now is that the pump on one of my H90s (top GPU) is making a humming noise. I THINK it's just vibration, and I need to tighten something down. (I suspect the fact that on ACX2.0+ boards you lose the top PCI bracket screw when installing the HG10 might be a contributing factor here). I haven't had time to address it yet though. Hopefully soon.
  12. Does anyone know the screw size of the little screws that hold the bracket to the video card? The HG10 manual calls them M3 screws, but I have compared them to some M3x0.50 screws that I have, and they seem smaller, so I think it is wrong. The reason I ask is, that when installing the HG10 bracket on my EVGA ACX2.0+ cards, you have to remove the black heat spreader that sits underneath the ACX2.0+ heatsink. When you do this, you lose the tapped hole that holds the top of the PCI bracket to the video card. I'm looking to get a couple of nuts, so I can screw the bracket back on, but I just don't know what size they are. My computer has a very annoying sound that correlates with the pump on the H90's. My theory is that they are vibrating the video cards, and this is creating noise due to them not being tightened down to the PCI slot cover. Appreciate any thoughts.
  13. Well, the beauty is that the blower doesn't have to be very effective. It only has to deal with the VRM and RAM heat, the AIO cooler takes care of the GPU. My understanding is that leaves very little heat for the blower to deal with. It is probably WAY overkill for what it needs to do, and in fact I'm counting on that, with my voltmod for the blower, making it spin much more quietly.
  14. Just did my first install. I followed Corsair_Dustins unofficial fix to place #6 washers between the Asetek bracket on my H90, and the standoffs on the HG10. I also peeled the purple thermal pads off the HG10's and placed them on the boards during install. I used the Intel brackets. I only installed once, and then went to test, so no retries thus far. I have minimal to no warping of the boards. If there is any at all, it's tough to tell, and only questionable at some angles. ___________________________________________________________________________________ Baseline temps using ACX2.0+ Ambient is 68F/20C for all tests. Unigine Heaven @4k, 8x MSAA, everything max. Stock fan profile. Top GPU (ASIC 82.3%): 83C, 70% fan Bottom GPU (ASIC 71.0%) 74C, 40% fan Manual 100% fan: Top GPU (ASIC 82.3%): 73C Bottom GPU (ASIC 71.0%) 58C Heat rises, so we always expect the top GPU to be much hotter, even though in this case it is the higher ASIC card. ___________________________________________________________________________________ Temps with HG10, H90 and my custom wires harnesses Stock fan profile. Top GPU (ASIC 82.3%): 68C, 20% fan Bottom GPU (ASIC 71.0%) 62C, 5% fan Manual 100% fan: Top GPU (ASIC 82.3%): 55C Bottom GPU (ASIC 71.0%) 42C Some notes: I use two Noctua Industrial fans for each H90 in push-pull. They are governed using PWM from the video card. These fans can move LOTS of air and are LOUD at full speed, but very quiet at minimum speed, and will actually turn off, if given a 0% PWM signal (which the default ACX2.0+ bios will do below 60C) My results are perplexing me though. I was expecting the "top GPU is hotter" result to go away, as all the heat is being sucked out the front of the case, but my top GPU still runs about 12-13C hotter than the bottom GPU, despite having a much better ASIC quality, which means it should be cooler, not hotter. Part of this can be explained by the top H90 being right above the bottom H90 (they are touching) and I imagine some heat rises there. But I don't think that explains everything. I suspect I might have gotten a better mount on the bottom GPU than on the top one, but I am not sure. ___________________________________________________________________________________ I'm not sure, as it was a major pain, but I might try a remount of the top GPU to see if I can get better temps. I'm still holding off to see what Corsairs solution will be. Sorry, no pics. I still need to do some buttoning up, routing wires, etc. Will post in a few days. edit: Just to test I disabled SLI and re-ran heaven. Top GPU temp was mostly the same, so I am fairly certain I have a worse mount on top GPU than on bottom GPU, and that it has little to nothing to do with GPU position.
  15. I'd be a little disappointed too, but on the flipside even a poorly performing mount like this will still be venting the heat outside the case instead of inside of it, and is probably a good deal quieter than an aggressive ACX2.0+ profile.
