I think I noticed this same thing when I got my HG10 on and H90s going. It was loud but it didn't make any sense. At first I thought it was the pumps, so I unhooked all of them. The sound was still loud. I plugged them all backed in. I noticed that the sound was coming from the blower fan, it has a fixed minimum of 50% and it was very loud. This was probably my main motivation moving to the kraken g10. The blower fan is loud even at the minimum setting, to me this eliminated the benefits of water cooling, but maybe not for everyone Try to manually stop your fans with your hand while the PC is on desktop, I bet you notice the sound goes away. Good luck

You could probably sell those cables. One thing I was thinking though, not sure I know enough about the DC electrical but I think you'll end up with a max fan speed equal to (5/12, 42%) of the the designed maximum. This would mean your minimum speed would be 40% of that, or 17% of max speed. When the card is under max load your fan will be providing a fan speed equal to the minimum on the default power. I don't know if this makes any real impact but something to think about. I just don't know why they made those fans stay at 40%. Most people installing these kits are likely smart enough to know not to run it at zero when you're gaming.

More likely is that your ambient temp is actually 21'c as a radiator can't decrease temperature below ambient. We don't refrigerate our radiator becasue if we did cpu temp would go below ambient and we'd get condensation. Same as when you take a cold beer out of the fridge and place it on the counter. Anyway, your temps look very similar to mine on the G10. At my base clock of 1328mhz (EVGA SC+ ACX 2.0) and an H90, in SLI I get Idle of 23'c Peak load in furmark about 15 minutes = 39'c on both cards! with case on. My max overclock is about 1500mhz on both cards and the temps go up to about 43'c with voltage +87, 110% card power. I saw very similar temperatures to thedudelasse when I got my HG10 N980 to mounted properly. I still think that regardless of how good you mount it it's still a bad mount.

I've given up on the HG10. Especially since getting the G10. G10 gets exceptional temperatures, even in SLI and it's simple to install. I'm hoping to slot away quite a few hours of fallout 4 this weekend, in silent gaming! That's a good idea though with the fan. I was also thinking another method would be a fan controller which would cut power.

I am not to familiar with that motherboard. It looks like it's compatible with fan xpert and ai suite. The limitation I was talking about is that in fan xpert you only get the choice to link to 3 temperature diodes. One is the pch (chipset), cpu, motherboard temperature (not sure where the diode is). So you can link any header on the board to either of those three diodes. on my motherboard the CPU is the only header that needs a fan attached or the system will error. You can remove this error though if you don't want to use teh cpu header. The others have no limitations

Wow looks great. One thing I considered with the fan was to hook it up to the motherboard (you will need a converter). That way you can cut power to it (on my Asus I can anyway, I think others are probably the same). Basically it auto turns the fan off. The issue with that though is it will be linked to the CPU temperature and not to the GPU but I am sure your CPU temperatures go up when you are gaming. It would give you a way to control the fan when you're not using the video cards.

It's very noticeable, I have the same card and when I hooked up the hg10 I noticed it right away. The fan cannot be turned down below 40%, eventhough the EVGA card allows for that, it just won't go any lower even if you set your own fan curve. Apparently it looks like they've put a minimum fan speed requirement through the PWM. My system in windows desktop was silient before I put the HG10 on so I noticed the fans right away. That was one of the selling feaures of the EVGA card, silent at idle. I actually saw really good cooling results from my HG10, but the fan was so annoyingly loud compared to the stock acx 2.0 that drove me to get the G10. To me, having a fan that is loud at idle removes the benefit of going for an AIO.

I think my ambient temp is about 21'c or so. Last night I ran at stock for the 4995 at 100% fans and I recorded a 34'c load temperature!! after 30 minutes of furmark. The HG10 just doesn't get the same contact to the gpu I want to get heatsinks on my vrms so I can put a bios on my card to increase voltage. How did you attach your heatsinks? I bought these ones: http://www.amazon.com/Cosmos-Aluminum-Cooling-Heatsinks-cooler/dp/B007XACV8O/ref=sr_1_3?ie=UTF8&qid=1447255807&sr=8-3&keywords=ram+heatsinks The fit perfectly on the idividual mosfets but I'm having a hard time getting them to stick, it seems like its hard to get tape to stick to the back of those chips? How did you get yours to work?

I received my G10s today. I took the HG10 off and replaced it with the G10 to compare. Yes I know no vrm or ram cooling, but with the mount on the HG10 I am not sure you're getting anything that will cool better than just air. I bought some heatsinks to go on later. Anyway on to the results. I've installed on one card so far. H90 push/pull in open case. Corsair N980: 28'c idle, 55'c load stock clock (fans at 100%, 4995 card) Corsair N980: 28'c idle, 63'c load overclocked (fans at 100%,+87mv,110% power, ~1450mhz) kraken G10: 23'c idle, 39'c load stock clock (fans at 60 %, 4995 card) kraken G10: 23'c idle, 42'c load overclocked (fans at 60%+87mv,110% power, ~1450mhz) I think those results speak for themselves. It all has to do with the mount difference. The G10 gives a far better mount and you can see it in the results. I am blown away by these temperatures, they are from furmark for 30 minutes. I even increased my overclock and almost got to 1500mhz, on my low asic card. Even better the fan is quiet and I can set it to zero rpm. I think I'll return my N980, sounds like corsair is leaning towards recall anyway. Not a great execution but I hope they continue to push forward on PC development, one bad product isn't so bad.

I agree, a recall would make sense. I'll hold on to mine and see what they say. I look at the kraken g10 and how simple the design is then look at the N980 and see how infinitely more complicated it is just to avoid having an additional back plate and to support VRM and ram cooling The whole idea was that you could cool your vrms and RAM all in one. Well with a curved board and not all ram or vrms being covered I can't say you get the greatest vrm and ram cooling. I think the G10 with cheap vrm and memory heatsinks may out perform and likely be less stressful installing. I still don't get why they didn't do a through board design, I mean this is aftermarket upgrades. People who use these types of kits are probably most concerned with performance and looks second.

Nice quiet fans that makes sense. I agree that's most important over cooling anyway, I don't think anyone gains much from 5'c cooler when they aren't even overclocking. I still think your idle temp is high at 36. You might want to try adjusting a couple of the bolts a bit tighter while running a benchmark and see if it changes at all. Of course be careful if you do this, it isn't the safest thing but with these brackets I think it might be the only way to get the best mount. I ordered myself two G10s to compare to the N980. I will post results when I've installed them.

I think you should be getting better temperatures than this, even with an 80i GT. Are you using a push/pull configuration? It's very likely your mounting isn't 100%. It's probably impossible with this bracket to get a perfect mount. Reason I say this is because if you read reviews of the EVGA Hydro card, it has 120mm liquid cooler and peaks at 50'c under load while overclocked. I have two cards. EVGA superclocked 980tis and in SLI running heaven/furmark they both peak in high 50's, say 58/59 (I am using push/pull H90, no break in period). At idle they go almost as low as room temperature (27'C). Your high idle temp leads me to think you have a bad mount. Unless you operating in a sauna. Also, I saw a youtube video yesterday with an 980ti hooked up to a G10 kraken and he peaked at about 55'c in heaven (with one card).

Well I can almost confirm they've done what your saying. I am talking about the blower fan, does seem to not go below 1600rpm, even if I set the fan to 0%. In my opinion they are loud enough that it really hurts the whole AIO idea. In fact, my PC is way louder now all the time but probably only slightly quieter when gaming. I also took the bios and looked at it, it's set for 0% minimum which is what I would have expected. This almost means for sure the fans are coded to not below a 1600rpm Corsair anyway for me to turn this off?

I've noticed something about the HG10 which doesn't make sense to me. I had two EVGA 4995 cards which I've put the HG10 on. I assumed that I would be able set a 0% fan profile exactly how my stock card allowed. When I'd use desktop applications the cards were completely sient. Now the fan will not decrease below 50%. It doesn't seem like the card responds to anything less than 50% of cooling. I can go up to 100% but can't go below 50%. Any idea on this? I want to avoid flashing my bios etc as it seems to be a bit risky.

I used 3 standoffs on each cards and used 1 long case screw with washer. I thought about using just the screws but not sure that would be any better. I was just happy I found something that would let me complete the project today. Setting it up is difficult, not like a cpu. CPU is brainless just screw it down. With these you need to tighten a bit, check it to see if it's properly sitting adjust and continue. One thing I learned is it's almost impossible to break your card, you should have seen what I did to my cards today. Don't be shy with the install I think this is hurting a lot of people, they are scared to bow their cards at all. Your card will bow. I can post some pictures, but I don't have an account on any image website. I wish we could just attach them, seems a bit ridiculous we can't.

It's a delicate exercise. Not as easy as CPU install. Install the bracket first with screws. Then put the coller and slowly tighten it checking to make sure it's balancing properly, check if you see any thermal paste, if you do readjust your cooler screws and move the cooler around. Tightening the back plate screws or the cooler screws essentially accomplishes the same thing, you don't need to overdue both or you end up with U shaped card. Its a bit of give and take on that one.

I spent the best part of Saturday installing this bracket on two EVGA SC+ ACX 2.0 cards. I had the same issue many readers are reporting, putting the bracket on and noticing temps are worse than stock cooler. I broke two standoff bolts in the process also, I found a work around for that: There is a long case screw with added washer you can use instead of the standoffs. The longer type of screws usually come with most new cases and have fine threading that works perfectly with the HG10. I can post a picture of one. The secret to getting a good mount is first adjust your heat pads, the ones on my brackets were terribly placed. Second, you need to use minimal screw pressure for screws holding bracket to card. The main pressure you want is from the cooler pressing down on the card. Once you tighten the cooler on the card tilt it up to a light or use iphone light to see if contact is being made. All occasions when I had bad temps I could actually vaguely see cooler not seated properly. Essentially the rule here is if you can see any thermal paste your not seated properly. In all cases (10+ mounts) where the temps would go up quickly I was using the INTEL bracket, I noticed using the AMD bracket seemed to take a lot easier. I think moderate bowing is impossible to avoid. A lot of people are probably scared by bowing, I can attest the cards are fairly robust and can take a bit of bowing. On my cards one side you cannot tell, the other side has a small bow. The results: 2x EVGA SC+ ACX 2.0 2x H90s Stock cooler: Temps 30/83 (ambiant/peak) for top card, 30/76 (ambient/peak) bottom card, running furmark With 2 H90s and HG10 N980: Temps 30/56 (ambiant/peak) for top card, 30/53 (ambient/peak) bottom card, running furmark I gained about 30mhz on my overclock so far, I can hit 1525 on one card, and 1465 on the other. Almost a 30 degree drop. Well worth the aggravating afternoon, I wish everyone luck with their brackets.
