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...

Zen is a very different CPU architecture from the Bulldozer variants. It is focused purely on SMT rather than CMT, for instance.

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: 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...

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...

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.

Bump for latest info.

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 ...
