Re: Electronic Noise and Tinnitus
I had the same problem, only less dramatic, with the previous machine which has completely different parts (Intel Lynnfield versus AMD FX) and a different monitor. I thought it was audible fan noise that is the source of the problem but I'm strongly thinking it's some type of ultrasonic or a high fr...

Re: AMD Wraith: Upgraded Stock Cooler
Zen is a very different CPU architecture from the Bulldozer variants. It is focused purely on SMT rather than CMT, for instance.smilingcrow wrote:Looking forward to Zen which will actually be a relaunch of the current CPUs but priced $50 higher
Not only that, it is built on a 14nm process instead of a 32nm process.

Re: Electronic Noise and Tinnitus
I'm really annoyed because I kept spending more money making my new computer more and more quiet in the hopes of being able to have a gaming and video encoding PC that doesn't cause tinnitus. But nothing has worked. I bought a 1200W PSU to reduce the fan noise. I put together a 480mm + 360mm radiato...

How loud would 21 500 RPM 120mm Gentle Typhoon fans be?
If one were to set up a watercooling system with two 1080mm slimmer profile radiators and 9 of these fans on each in push configuration, would the noise be quite distinct? There would also be a 360mm radiator connected with three in push. They are rated at 5 dB each but I am wondering what will happ...

Re: Ultrasonic commutator and tinnitus
The radiator has three fans and the GPU has two. All are ball bearing models. I don't know if any of the sleeve type fans in the system have ultrasonic commutators. The trouble with my tinnitus is that when it gets aggravated the sound lasts for weeks. So even if I turn off a fan or all of them the ...

Re: PC in aquarium full of mineral oil
But then your PC isn't fully submerged in liquid, it's running on CPU/GPU blocks, the PSU fan will be audible, ect. The limit of oil is it's surface area, which scales poorly, requiring far greater oil volume to make up for the 'low' surface area. Say our CPU heatsink alone has 880 sq/in (44 fins a...

You seem to have tested a lot of the top end from all the good brands.

Re: Seasonic Platinum 520w (SS-520FL2) - Recommended?
The quietest power supply with a fan at lower loads seems to be the Corsair RM 850. The only drawback is that it uses a lot of Chinese capacitors which bothers some people since it has a 5 year warranty and not a super long one like some other brands do. But, unlike most "quiet" high wattage power s...

Re: How accurate are product specs?
Ignore CFM and decibel ratings on fan packaging. Read credible review sites' testing results. The only reason fan companies get away with lying is because no one has bothered to sue them. That's the conclusion I've come to. While there may be a select few who post accurate specs, proof is really nee...

Bump for latest info. It seems weird indeed that there are two simultaneous premises: 1) Larger fans move more air with less noise 2) Fans larger than 120mm are noisier for the same amount of cooling The only answer I've seen to this conflict is that manufacturers have had more time to perfect the d...

Re: PC in aquarium full of mineral oil
The only way to get the aquarium mineral oil cooling system to work with a high powered gaming pc is with a rly heavy duty pump and a pretty large heatsink like 420mm x 280mm (6x 140mm fans or 12x in push pull) or even a 420mm x 420mm (9x 140mm fans or 18x in push pull). It could still be silent th...

Re: Multiple fanless power supplies?
I suggest you don't encase any noise makers -- like 18 fans. Leave them as unenclosed as possible to avoid the air resonance effects you'll get when you enclose (or even partially enclose) any noise maker. This is interesting. It sounds like having equipment outside of a case is better than having ...

Decibels don't just disappear because some other component produces more of them. Actually... they kind of do. Let's say your PSU w/ a single fan measures 12 dBA@1m. And your 18 fans -- :lol: -- measure 20 dBA@1m. The total SPL from the setup (assuming it's all more or less in one area/case) will b...
