not even measured, at this point it changes so little because of room noise that it's not worth measuring usually

GPU is here, gave it some tests

under 60°c, the fans turn off. it idles around 50°c in my case with a room temperature of about 20°c. fans are not audible above the vent noise in my apartment when they turn on.

very happy with this GPU.

just ordered a new gpu to replace the clicking one, decided to go for an rx 570, will report on its noise when it gets here

The CPU is thermally rated for 95w and only uses up to 70w at full load, I'll be fine while I'm still using this processor.

TDP specs are usually set around one number; the ryzen 5 actually has a significantly lower usage than the ryzen 7, but the spec says they have the same usage. This is counter-intuitive for people depending on exact numbers to be published but is fairly convenient for preventing people buying 30w co...

well, I can still hear it, since the GPU is fairly loud, so I'll be replacing that, and the PSU is still loud, so I'll replace that too. EMI issues persist but I've switched keyboards temporarily (packed up the big one for moving) and the issues went mostly away, so I'm definitely getting a new keyb...

cooler is here. Much quieter.

SNR at mic is now about 55, this time I did the measurement correctly (last time I was measuring with a weak "aaaaaaaa", this time I measured with full-volume talking at the correct distance from the mic, previous SNR with just the case was 50)

Cooler size comparison.

well, as said before, I'm moving soon, and my new place will be much quieter, much better for recording. also, it seems after some cleaning and temp testing that the cpu cooler didn't quite need to be replaced yet, except for the clicking, but I'm moving soon and need to have this money on hand so.....

unfortunately I did the SNR calculation by hand using a dB meter. To note: I did this in windows, which doesn't let me solo my mic input from my guitar input on my interface, so there's a -52db noise floor from the guitar preamp. I don't have software to measure dB in realtime in linux, even though ...

sorry for double posting twice, case got here and I installed the computer into it.

aside from being kinkin "new case, no post" kijkin, it's increased the SNR at my mic to 45 from the previous 32, and improved cooling, so I'm already liking it. Cooler hasn't shipped yet.

Yeah, this makes no sense. Keyboard supply voltage is 5V for both PS/2 and newer USB. There is no high voltage or low voltage involved. I am assuming this is a wired keyboard and not a wireless one... keyboard is wired, and other keyboard collectors have noted similar issues with their early model ...

ordered the bequiet cooler recommended to me, and talked with some keyboard folks about keyboard EMI. apparently a very common issue with high-voltage keyboards like my own, and circumventable by using a low-voltage and/or high polling-rate keyboard, as I suspected before. Both the cooler and case w...

effective but... will they actually fit in any real, existing case?

I'll definitely check the wall sockets if it persists when I move. On the case of audible noise, I was just able to order the Define C just now but not a cooler with it. I'll be purchasing one of the coolers in not too long, but for now I hope the case alone causes enough of an audible noise decreas...

Case: I think, given your power load, the included fans should be fine. Try them out - you can always adjust as part of the build - and once you start down the quiet-my-pc path, there's always the next thing to work on :) No need for foam/etc. When you go with a well ventilated case and quiet compo...

Ok, thanks for the info. 1) Get a new case. One of the primary purpose of a fanned case is to move air through it and to remove heat build up around the CPU/GPU. So, your current noisy cooler isn't getting the benefit of this airflow...and while it won'tr solve the cpu cooler problem, it'll help in...

Welcome to SPCR. I infer from your comments that this PC is used in a live mic environment? Maybe you could detail your applications and s/w so we could provide better answers. Some questions and comments: 1) What's your budget for now and future? (Best way to prioritize fixes). 2) How are you cont...

wave would be the best quality, but is uncompressed

AAC is the second best quality and nicely compressed

surprised you can't save as FLAC though, that's compressed with no loss of quality over WAV, though a lot of devs are slow to support FLAC

Recommended articles seem to not have been updated in multiple years, so here I am. My room SNR is 32db thanks to my loud computer and untreated walls, latter is being taken care of when I move soon, but I need some help with the PC. Currently, I use two SSDs, a 7850 (inaudible over the other compon...
