Hey, nagi, I'm sorry I didn't see your post earlier. That is very interesting information and pretty disappointing. According to BQ my fans will stall around 5 volts, so if I don't have at least three on the phanteks then it would be pretty bloody useless (and even then they may run too fast). I gue...

That Phanteks part looks perfect! I might see if I can build one myself from an Arduino as a project, but the splitter you posted is a good option.

I appreciate the response. When I say three fan headers I am not including the two CPU headers which are consumed by two CPU fans. There are only three controllable case fan headers on this motherboard. People who want more are expect to pay an extra 100-150 dollars for the Extreme edition which has...

I feel like this should be a basic question, but after several years messing with PC silencing I still don't know the answer and my google-fu is weak on it. I recently had to replace my X99-A motherboard with a Crosshair Hero VI (don't buy X99, 5930k CPU for sale!). This has reduced me from four fan...

I'm a little confused. Coil whine occurs even in cards that don't have custom coolers on them, and MOST people don't use zip ties to secure their card, so I'm not sure how this helps us figure out the "cause of coil whine" under load. =\ That is not my thesis. What I found is that torsional stress ...

For a while now (months) I have been dealing with increasing noise from my GTX 1060 while under load. As frequency increased, so would the pitch of the noise. I run F@H on the GPU at all times, so this was a real problem. However, I believed there was nothing I could do about it. I have just discove...

I am getting near the point where I am ready to put together a build guide, but I thought I should update this thread with my last results. When I returned home after two weeks I found that my temps had dropped below 70 on all cores at an ambient of 24 (The A/C was fixed while I was away, hurrah!). ...

re: 650 min RPM: have you tried combining PWM and undervolting the fan as well? Maybe that'll help, although I don't know, I usually try to stay clear of PWM. I'm not sure exactly what you mean, but currently on the CPU I have a pair of 3-pin fans with a resistor on each to keep it down. I don't th...

I'm going away for a couple weeks starting tomorrow, so here is a quick rundown of where we are. I haven't gotten a stable 4.4 GHz yet. Increasing vCore hasn't gotten me anywhere, though it will run for more than 24 hours before crashing. Right now I'm leaving it at 4.3 and will look at other settin...

OK, just re-did the GPU and now it's ~67°C with ~1400-1500rpm stable under furmark, with OC. IIRC I used the paste that was pre-applied to the cooler, maybe that was the problem, maybe something else. I also removed the extra heatsinks that might have collided with the cooler and thus borking the h...

In my experience PWM fans can produce what oyu describe - coil whine - when controlled through PWM signals. Even high-end Noctuas. I suppose it is some form of coil whine, but it was very strange. It sounded almost exactly like a dial-up modem. I have experienced this sound or similar with Noctuas ...

I suppose it is some form of coil whine, but it was very strange. It sounded almost exactly like a dial-up modem.

So, today's strange news. I had everything pretty close to where I wanted it in Speedfan on Friday, then we went away for the weekend. I came back to find my computer making a bizarre chirping noise. I used the "jam your finger in" test to make sure that it wasn't coming from any of the fans. It sou...

Furmark temps: With OC, (+75%core, 120% power target, +90 core clock, +400 memory clock) ~1700 rpm will keep it at or under 71°C. Without, it's stabilizing at 1500-1600 and 69-70°C. That does sound a touch high in temps and fan speed, though of course Furmark is the great VRM killer to it isn't out...

Since we're talking about TIM, have either of you ever experimented with the Coollaboratory products? They appear to be massively effective performers, and I'm wondering if they really as risky to install as some places are suggesting. Well, it's very easy to just twitch the brush and let some of t...

That's rather good: you should be able to shave off a couple of degree with some (more expensive) higher performance paste (like the Prolimatech PK3 or the Thermalright Chill Factor III, IME), but the MX-4 is quite good. Based on the comparisons I have seen, it seems like by far the best price/perf...

Can you see a change after the thermal paste reinstall? It's hard to say because I did a whole bunch of things in one go, but my instinct is that reapplying the thermal paste and doing a clean installation of the cooler led to the largest change. One thing I'm going to do is get my hands on a large...

did you just remove the HDD cage or did you even mount a second front intake fan? Just removed the cage. I don't expect this made a huge difference, but my reasoning is that there was no reason not to do it. At worst it will only marginally improve airflow and turbulence. About the thermal paste, w...

Most recent changes: Flipped the PSU (Did this yesterday. The difference was marginal, but better cable routing is possible with it flipped) Figured out how to override most of the motherboard's fan control so that Speedfan can stop fans. Removed the Ninja 4 and reapplied thermal paste, this time ge...

About running at full bore at high temps, well, I think you could brush up on SPCR fanless PSU testings . That's actually very compelling. I get the reasoning behind flipping the PSU, and given the results you pulled with the 400W Seasonic (which is basically the maximum wattage I pull from this un...

My guess is that trying to have an intake at the top of any case is not going to be helpful. The natural convection is for warmer air to rise, and the best air flow set up works with this; not against it. That was my feeling also. Installation and / or CPU spreader flatness is something we haven't ...

Do you mean as a top-front intake or top-rear intake? I haven't tried either. Flipping that top fan is such a quick check that you should. And I certainly will give it a shot when I get back home. If you mean flipping it on its top so that the vents face down, the manual specifically says not to do...

I have a 140mm Silent Wings 3 as a top-rear exhaust fan Did you try it as an intake? And what about flipping the PSU? Do you mean as a top-front intake or top-rear intake? I haven't tried either. If you mean flipping it on its top so that the vents face down, the manual specifically says not to do ...

We both had issues until the side door was removed. Your case looks like the intakes are more constricted than on mine - and until I added the top 140mm fans, mine had issues. Your case also has more internal obstruction - the drive frames, in particular. The Ninja 4 is one of the best coolers, and...

NeilBlanchard wrote:Are you using a top fan(s)?

I have a 140mm Silent Wings 3 as a top-rear exhaust fan, and the top-front mount is exposed because air likes to flow through it.

What is your reasoning about the case as a bottleneck?

While I haven't finalized the whole system yet (which could take weeks as I have to tweak and test OC settings), I thought you deserved an update because I have made good progress. I managed to coax two 140mm fans onto the Scythe Ninja 4 (a Silent Wings 3 on the intake and Silent Wings 2 on the exha...

BTW I think you have to tinker a lot with the controlling method, to reduce the noise: I wish you every success in your work. Thanks, I will keep this thread posted as progress is made. I am already seeing gains from fitting a 140mm on to the Scythe (thought it required a barely adequate kludge inv...

Personally I'd try to follow a different approach, I'd try if the SW3 140 HS alternative anti-vibration corners were somehow compatible with the Ninja's clips: in case, your heatsink should sport two pairs of clips, so my first move would be moving the 2 SW3 140 HS from the case exhaust (a bit poin...

It does, but only on the intake panels. I will experiment with removing them, though I suspect that the underside one may be worth the restriction.
