First build for Day Trading - Advice?

Some info:

1. 90% of the noise of a system on air comes from the gpu's fan when under heavy load.

2. to get quiet pc you need to put everything on liquid cooling, this will go over your budget but still with lc you are still dealing with fans, so if you truly want a pc is quiet, you need to go custom lc and custom fans, and that really goes over the budget.

3. now for your use I don't see gpu fan noise being an issue but you sound like you are very sound conscious and I'm not sure how an air system will sound to you, to me it would be ok but to you it maybe loud.

Now I can simply tell you to get this and that and you will be fine but I'm not the type to guess things like that so please let me know what you think about this info.

we can use noise suspension and lower fan speeds but in return your temps could go high at your house and then you would need to set the fan higher and thus more noise, which is why I think its best to go with a quiet fan/setup right off the bat.

To be honest as I'm trying different configs, the hydrolux pro (the lc system) is pushing us to over $2500 and that is with a 1060 and an i5 6600k, which I rather have you in 6700k which then pushes us to around $2700. And we have not even got to asking DS to install quiet fans on the pc / lc system.

I would put you in a lower lc system but I'm not confident about the noise level.

How would you like to proceed?

for example I could tell you to get a bolt like this config but I'm not comfortable with doing that, both for temps and noise:

Ticket Number: 1470925



the other build I would feel comfortable recommending as a base,(as in a start point to which we still have to make modifications to) is this one but as I mentioned the price is above your budget:

Originally posted by mikeb029 Now I don't know if I'm being too conscientious about fan noise or if these machines are just loud. For example, in your opinion, is a non-lc DS machine louder than, say an Ibuypower with same specs? If not, than i'd probably be OK with it. Does DS publish Db ratings? $2,500 is over budget...we'd need to keep it down around $1,800-$2,000. thank you......

With no games or streaming I doubt you'll hear it too much according to the reviews. I haven't received mine yet, so I can only speculate

May have more storage than you need too. If so, removing the mechanical drive would reduce a bit of noise. Added premium fans too.

IMHO with 4 monitors you are going to have noise no air, I trade also with multi monitors btw myself.

if its the same fan for example you will not notice a difference no matter where you go.

so no DS system is no louder then any other systems with the same specs.

if you want to be on air then go with this for most power and least amount of noise on air:

Ticket Number: 1471462

You want brand almost all the time unless budget does not allow so that you know what you are getting, ram can be different a bit, for ssd I would only go samsung here.

No what I was saying is that if you are going to go with the builds you suggested then my build would be more quiet then the builds you suggested. Otherwise what I said before stands about most quiet system = cpu/gpu on lc = price higher than $2000.

you see the only way for us to make your gpu quiet is to put it on lc, a basic lc system will have loud fans if the system is going to get warm or hot. Now do I know if your pc is going to get hot or warm? I don't know, and instead of gambling with whether it will or not, I choose to take the stand that lets assume it will, in that senario what kind of cooling would do better? that would be lc, now if I want quiet lc then I have to put quiet fans on the lc system, for this we need to go hydrolux pro, HDpro will put us over the budget of $2000.

Hope that helps, Now theoretically if your cpu and gpu don't get warm enough, specially the gpu, so that it's fan does not have to spin higher, then you would be ok, but with 4 monitors I assume your temps will go up when you are running the interactive stuff.

build 1471462 will be quiet as long as there is not much load on cpu or gpu otherwise gpu on air + good load = high fan = loud noise.

Hope that clarifies, I'm not the type of person who is gonna put you on air and tell you that you gonna be fine when I don't know if you will for sure and it seems the noise is important to you, so I want to give it that much attention.

assuming the fans on the hydrolux lite are quiet then this build is what I would go with, again assuming fan on the rad for the lite version are quiet under load.

Ticket Number: 1471543

problem is they may seem quiet to us/me but not to you.

Slate has more fans which I'm not sure how loud they would be to you, I would assume the case fans will be quiet and should not bother you, that being the case then perhaps the slate would be more quiet but that will raise the price plus we are on air, which again I'm not comfortable saying that on air a system is going to be quiet.

db did you grab those from swiftech's site or a personal bench? I find they bs the numbers a bit.

at 43db I think he will come to my house and take my head off I think at 36db he is still not gonna be happy.

Thanks for the info db

also, i don't see much need for his usage to run the fans at 100%.  day trading programs aren't particularly demanding even with working on 3+monitors.   

i doubt it.  but i think Swiftech uses those NoiseBlocker e-loop fans, which are pretty good.  if he wants quieter fans he'd have to look at some Apache Black or GentleTyphoons i would think.

I was thinking SGT also, I think he wants to be below 30dba to be quiet, he is adamant about it being quiet.

agreed on gpu, which is why I'm telling him to put gpu on lc.

he said he has already returned a pc to a different builder due to noise.

Edited by DST4ME - 15 Aug 2016 at 4:41pm

well, he's restrained by budget and there's only so many options for his price range

it was whole system build, so yeah it included the gpu being ran under extreme load with fans maxed.  i can't remember the gpu model, but it was probably a reference card for testing purposes.  it was pretty amazing, i couldn't believe how good that 550D was from an acoustics perspective.  the thermal performance was midling, but that's what you get with a "closed case".   

well, it would probably consume his entire pc budget just to get him a silent custom open LC loop to do it really right.

Pretty close..thanks DB

Day trading?You will use multiple monitors and running many tasks at the same time?

Lots of ram and a cpu with many cores would be what I would base that build from.

So tell us what you think and what you are thinking now as far as noise and air and lc?

from Anandtech's review of the Corsair 400Q (DS Slade):

Thermal testing has been performed with all of the case's stock fan operating at maximum speed. Noise testing has been performed with a background noise level of 30.4dB(A). Advanced noise testing is also being performed, in order to assess the ability of the case to dampen the noise of the components installed inside it. This includes the installation of two noise-generating sources (strong fans) inside the case, one positioned approximately over the first expansion slot and one over the CPU area, which generate ≈ 44.2 dB(A) when unobstructed. During the advanced noise test, all stock cooling options of the case are entirely disabled.

(talking about the Corsair AF fans included) Combined with the sound dampening material, they made the Carbide 400Q one of the lowest noise ATX tower cases that we have ever tested. The Carbide 400Q showed very good sound dampening capabilities as well, reducing the sound pressure generated by our dummy noise source by 5 dB(A), from 44.2 dB(A) to 39.2 dB(A). The dB(A) scale is logarithmic and that translates to a sound pressure reduction of over 60%, which is easily discernible by the human ear.

they tested this case with an 820watts thermal load.
