The problem with watercooling to me is also the sound of the reservoir.. If I were to consider going for this, I'd probably think of a long trunking and try to leverage the use of my air-con units, at least one of which is going to be on anyway.

To get really low noise at low cost, if all other concerns were not critical, I'd just knock a hole in the wall and put the PC the other side really... too bad most of my connecting walls are to non-useable spaces (e.g. toilets, walkways or roof terrace).

Should be starting the build soon if my friend is up to it. Let's see how it sounds.. if not I can find alternative location to put the PC to get more distance from it.

Though my room is quiet, I think it should not be <10dbA anyway (definitely not during rush hour even though I have triple layered glass). 2-3 low noise fans should be able to achieve <15dbA and if I place it 4-6m away (as an option), it may be inaudible. My old Antec PC was about 23dbA with stock fans and that was abit noisy, but I think liveable with for some gaming performance.

sorry not familiar with watercool.. maybe what i meant is the pump. You need something to push the water right?

Dual core Atom, but still Atom. He wants an i7.

Built my i7 PC but waiting for a few more cooling parts to come in before complete. Temporarily bought some noctua stuff to use while waiting..

Installed Win8 and just compared playback of youtube to my existing PC.. so much details missing...

If I have time, will want to explore what's the difference.
Some things I can think of:
1. EMI/RF from fans
2. Different secondary HDD causing EMI/RF (though I am running both on ssd for OS)
3. Haven't found the right usb slot on the new PC yet....

Should have gone for a massive passive cooler instead of going with the Noctuas. The PWM controllers inside the fans will introduce way too much noise into your system.

Oh one more thing, you should have tried running a separate power/mains rail for your PC and another one for your stereo.

Am buying but i don't think i can go passive for the whole PC (GPU and casing) so that's a moot point.

Separate power mains is also another story.. I do have 3 lines for my setup, 2 of which can be used for my conditioner, but am using only one now. Other things make a bigger difference. In any case - the comparison is done using the exact same equipment as the first PC. Same power cord, usb, etc.

Anyway, just to report that even without the better casing fans, and CPU cooler, the normal noctua d14 with stock case and GPU fans undervolted is already decent giving a decent result though not as quiet as I'd like it.

My guess is around 20db with no load. Loudest thing in my room now (other than rush hour traffic).

You can undervolt the CPU and GPU as well to reduce temps if you're not OC-ing.

Just did some tweaking to the i7 to Win8 processes and so on.. brings its performance better in terms of dynamics but still a big difference in texture, detail, weight and presence versus the fanless i5..

That's what I meant about fans being an important piece of the story.

BTW, I've noticed that the general noise floor in SG is a hell lot higher than the village I lived at previously. Power also seems a lot more noisier, staying up late won't help matters too.

It's definitely killing the sound....not good.

So you believe all the difference is just the fans?

Have you been using a fanless PC by any chance?

Anyway, my own theory is still the same as above:
1. EMI/RF from fans
2. Different secondary HDD causing EMI/RF (though I am running both on ssd for OS)
3. Haven't found the right usb slot on the new PC yet....

Add:
4. More 'busy' motherboard with Z77 vs P67
5. Desktop vs tower casing and isolation


Before this gets out of hand, I'm going to say that I'm not expecting this i7 PC to be better than my i5.

Tests lined up in next few weeks:
- Seeing if any difference if adding SOTM sata filters which helped previously on WD Green
- Testing if FSP rack PSU in dedicated separate casing sounds better than my existing seasonic, and doing ground tweaks
- Jplay v5 beta on two PCs, network play
- Audiophilleo vs Legato converters
- Test on different methods of ripping via the new CD ripper
- Testing different footers on the power strip
- Miscellaneous in room treatment area
- More playing with torque
- More playing with TC to see if it is a true improvement

Sounds abit busy...

Hmmm, should I start showing off my HTPC? Hahaha, 20db on a HD6850 and 3770K!
Don't go philosophical on me and play retard.
