Hello all, Just wanted to ask if my temps are high for the Kraken X31 that I run with my i7 6700 (non K) I just move the componenets of my pc to another case (In Win 303) and I replaced the thermal paste, I used a small dot in the centre (I am aware of how much to use). With this in mind, I am getting about 30c at idle and I feel like its a bit high, Also wanted to ask if there is a reason that the fan on the radiator tries to spin on startup but cant quite spin properly, but as soon as I spin it a little or breathe on it, it spins just fine. Regards, Ghost

Hi guys! I just joined the forum, and I seem to have a small problem with my kraken x31, I'm using it with a G10 bracket on my 980 Ti, but I can't control the fan that is attached to the fan header on the kraken it self. I am running CAM 3.0.6 The krakens 3-pin power cable is connected directly to a molex-->3-pin (can still be controlled in CAM 40-100%) The internal USB header from the kraken is connected to the motherboard And the fan the cool the VRM is a 3-pin fan that is connected to the 4-pin cable from the kraken itself and it is in the "correct" fan header with the PWM signal the problem is that I can't control the fan for the VRM, it seems to be running at 100% all the time, which is loud! (some 92mm Noctua) is it even possible to control this fan or does that fan simply have to run at 100% all the time? BTW. my pump is rattling all the time even at 40% maybe the entire unit is faulty? Kind regards abger

I'm using Kraken X31 for my i7 4790 cooling. Bought it with one reason only ... it looks cooler with S340 case, rather than air cooling. But ever since I got it, it's pissing me off. Under CPU load, it will get kinda loud, even if fan and pump are both working with the same speed all the time. And yesterday I was playing with BIOS a bit and found another strange thing with it. For CPU clocking there are some setting to change multiplier for each core or for all cores. When I have it on AUTO it works okay (aside from that annoying loudness on high CPU load). But when I set in BIOS those multipliers to 40x (so 4GHz), Kraken will start ratling noises. it's comming from the thingy on my CPU (I guess there is pump there?). I have no idea why it does that. Temperatures of my CPU are just fine. Usually under 55°C. Any idea why my Kraken X31 is strating with ratling noises if I change multiplier to anything else than AUTO? Even if I put all cores to 36 ... When it's on auto I get 4GHz performance out of it without ratling noise. That thingy is just causing me headaches from the begining. I apologise for my grammar mistakes.

Hello everybody! I have ended the life of a EVGA 04G-P4-3975-KR 970 SSC ACX 2.0+ card & I'm coming to ask you guys for help. Obviously I've done something wrong & I'd like your input so the mistake can be avoided in the future. Hopefully this thread will not only help me out but save some other people from these troubles in the future. To start out I want to say I've been running these amazing bios from over on the Overclock.net forums for three months with constant everyday use. I ran this card at 1532 core & 7906 memory with no problems! I never adjusted the power via sliders or anything else once the modified bios were put in place, I just used EVGA's PrecisionX 16 software to modify the speeds & run a more aggressive fan profile. I had tested this card at higher speeds via AIDA64 Extreme, 3DMark Pro, Cinebench 64, & Valley Benchmark where it did fine. I bumped it down to those speeds for a little bit of safety instead of putting it on the very edge all the time. At absolute worse it would get to 80C with the fans at 100% sounding like a jet was taking off in my office. (though it never downclocked) Skip forward a couple of months & I was really tired of the noise. Specifically when I was doing video editing, the scrubbing would make those fans rev up and down enough to make you pull your hair out. Or even while streaming on Twitch, no matter how good of a audio filter you setup the noise could become a problem at times. Wanting to solve two problems at once I figured I could help protect the long term life of the card & bring it's noise down by installing an AIO water setup on it. I have alot of NZXT products in my build so I figured I would stay with what's worked so far & purchased a Kraken X31, the G10 mounting kit, some Noctua NT-H1 paste, & 16 additional copper heatsinks. I was worried there was a lot of this card that needed cooling that the fan included in the G10 kit wasn't going to adequately take care of. I have a ton of air flow in my case so I thought with some well placed heat sinks I wouldn't have any issues keeping this card nice and quiet while it screamed on those modified bios. So I put everything together & it worked great for a while. I wanted to see how it would handle maximum stress so I fired up every benchmark I could. This card would never get over 55C, it was rock solid & finally silent. I was in heaven for about an hour. I tested some additional overclocks just for grins. The card would bench at 1600mhz core & 8,000mhz memory but after a while would start to stutter. I kinda laughed that even on water that was probably pushing it to far so I backed it down to 1550 on the core & everything was fine. I mean that's only 18mhz faster then I had it running on air for months. I really wasn't concerned one bit since this wasn't about getting it faster. I had a bunch of work to get done so I just let it run endless benchmarks in the background to see how it was going to handle the new setup. About 45 minutes into this I got a business call that took me away from my desk for about 20 mins & being naive or just really dumb I didn't for a second think to turn off my stress tests. I came back to a black screen, the system was still on but there was absolutely no video response. From that moment on this card was officially dead. I tried separate PCI Express slots, I ran completely different cables from different ports off my PSU, I took the card out & put it in another system all together. Then I took an old Quadro FX 3450/4000 SDI card I had laying around & tested everything. My system was fine, I couldn't find any damage to anything but the 970. No matter where I tried to run this card, the systems would never power on for more then a split second. I mean you could push the power button & watch the system fans just twitch once not even really move. That was the fate as I tested it over and over. I removed all my mods off the card completely, reinstalled the default stock cooling system, & well you guessed it, obviously still dead. I got a magnifying glass out just to see if there was any sign of physical abuse on the card, like I nicked something during the mod or I don't know, just if there was any sign of what had happen. Nada, card looks great. I'm truly baffled as to what went wrong. I have speculated that a few of the tiniest chips I couldn't fit additional heatsinks on failed when they overheated. I'm also rolling the idea around in my head that I should have tried to install the X31 on top of the secondary plate that covered all the chipsets / memory instead of putting on all the copper heatsinks myself. I'm really not sure, I've highlighted the spots that didn't get new heatsinks in the pictures below. So I've got another of the exact same card coming. It'll be here Monday. Hopefully with all of your help I can install this X31/G10 on it & not ruin another $350 card. The sticky pads that came on the copper heatsinks have got to be dry by now & I didn't order any permanent bonding compounds yet as I wanted to hear what you all had to say before going down that route again. I watched a bunch of videos of people doing this same mod & clearly I've screwed up somewhere. ALL ADVICE IS WELCOME. Please use my mistakes as an educational grounds to improve your own future builds. Pictures in the spoiler box below: Thanks in advance, 'Gobby

Hi guys I'm looking for decent AIO water cooling for light to mild overclocking with cheaper price and I already have three candidates: NZXT X40 or X31, and Corsair H60 (Fyi in my place these three water coolers have similar prices). So what should I go with? Or is there any better AIO water cooler with similar price?

I recently built my first custom gaming rig and due to budget restrictions I went with the NZXT Kraken x31 over the x61. The actual cooling aspect works fine, and I can edit the coolers settings from within the CAM software. However I can't seem to get the LED on the pump to work. Iv tried disconnecting the fan header etc to see if a re-initialize would solve the problem, but with no luck. In the CAM software I have set a colour and according to the software the LED on the pump should be working, but when I look inside my case (Through the side panel window) there is ZERO light coming from the pump. If anyone knows of any possible problems/fixes for my issue a response would be greatly appreciated.

I'm thinking about getting an H440 or S340 and change my CPU cooler to a watercooled AIO. However the S340 can only mount a 360mm (like Kraken X61) in the Front, in the rear there is only an option for a 120mm Radiator like the X31. Now in order to get a good airflow, I would need to have the X61 pull in air from the front and have the supplied fans push it out in the rear and the top (or just the top if I get a 2nd X31 for the GPU). If that is actually a bad choice as mentioned by someone in a couple of threads below (didn't want to hijack it thoug), why did NZXT design it like this? On the other hand if I get a H440 I have more options, like mounting it on the top and have it blow out air through the radiator. However due to money constraints I'd like to go with the X41 since it's 50 bucks cheaper, and that one won't fit in the top, so again it's leaving me with the choice of front or rear. For reference I created a table already according to NZXT compatiblity charts: H440 | S340 Rear: X31 / X41 | X31 Front: X31 / X41 / X61 | X31 / X61 Top: X31 / X61 | None So what would be a good and cost effective setup with two Krakens (one for CPU and one GPU, not overclocked but i7 and GTX 970) in either the S340 or H440? Can anyone shed any light on this please? How to arrange both AIO and other fans.

Hello Again Community I have a question to ask of you My h100i is currently suffering and beginning to fail, Now before this post goes RMA crazy, I dont want to replace it with another h100i, I'm looking to changing it out for something completely new i was thinking about the kraken x31. Now i know what your thinking "its only a 120mm" where as the h100i is a 240mm. but im very limited for space in my obsidian 250D. I do have another post on the forum about water cooling the 250D but have run into a snag. parts are expensive and i recently purchased a wb for a gtx780ti reference from someone on the forum and i neglected to research the different positions of the Caps on the pcb so the ekwb will not fit unless i modify it but im too afraid to do that. SOOOOO My question is will the kraken x31 be sufficient for i7 4770k OC'd to 4.4ghz. or should i find another 240mm aio that can take the place of the h100i. Specs: everyone likes specs case obsidian 250D mobo asus maximus vi impact (be mindful of the daughter board when suggesting Aio, rad thickness cannot exceed 27mm) cpu i7 4770k OC'd 4.4 ghz ram 2x4gb g.skill ripjaws z 2400mhz gpu just upgraded from reference asus gtx 780ti to an asus gtx 780ti direct cuii oc psu bequiet dark power pro 10 650w the rest is irrelevant what do you think, let me know if the x31 is too much of a down grade
