*4* GPUs? Wow - I take it you've some funky vehicle or aircraft simulator
running?

Anyhow, just thought I'd follow up and say thanks for all for comments. I
ended up getting a Core 2 Duo E6850 with an aBit I35-Pro mobo. The Zalman
CPU cooler is fantastic and the PC is just a quiet hum in the background
just as these things should be. My GPU has a heatsink, no fan so I guess
thats lucky.

A little OT but I also plumped for a 64GB SSD and am trying Ubuntu 12.04
with Unity (!) as my main desktop. From Grub hand-off I get to the login
screen in about 5 seconds :-)

I was intruiged by the remote desktop/VNC/SSH forwarding style
suggestions and will maybe try them out as an experiment.

Thanks again guys.

 Heh. If you think the CPU fan is the loudest noise, you haven't heard
 a gaming rig with 4 GPUs... :-) The loudest noise in my study (which has
 three running computers in it) is my GF's video cards in the next room.

 (But then admittedly, if you're going for something quiet, you're

Re: [Hampshire] Quiet and cool PC running?

2012-05-05 Thread Ian G
undervolting works well. its also important for either chassis fans to maintain 
a flow of new air rather than allowing ambient temperature to rise inside. 
pastes are good but again needs to be accompanied with sufficient cooling. 
liquid coolers are cheaper these days, but for a p4 would probably be overkill. 
i find AMD cpus harder to cool, but bios/emi on modern chips have the Cool 'n' 
Quiet feature which usually just throttles the CPU to prevent heating + fans 
sponning harder.

Bear in mind that NX is no longer Free Software. The older versions were,
but they've moved the current release to a proprietary licence.

Older versions are still available - and work pretty well, IME. Google

Re: [Hampshire] Quiet and cool PC running?

Last year whilst rebuilding my PC* I bought a PSU with a huge fan 
(Maplins); I am very pleased with the resulting peace.
The fan is controlled and in very hot weather can run a little faster; 
there are no case fans and no rhs side-cover.

The PC is in front of my shins so the quiet is very welcome.
*2-core AMD 64-bit, fanless graphics card - all recent but not cutting 
edge because bought for domestic use with Linux.

Re: [Hampshire] Quiet and cool PC running?

2012-05-02 Thread Gordon Scott


FWIW, there are a number of quite impressive coolers around (at a price).
The heat-pipe types are particularly effective, and yes, the Zalman's 
are good.


These people have a wide range, including both heat-pipe and water coolers.
http://www.overclockers.co.uk/productlist.php?groupid=701catid=57

Sadly few manufacturers or suppliers quote the performance of their 
coolers in an absolute form one can use for calculation.


Incidently I've seen people buy big, expensive, coolers that keep their 
CPU to below 40C, so well worth the cost. If you're not doing risky 
things like overclocking, your CPU should be fine if you keep it below, 
say, 80C. You'll not destroy it even if it gets to 100+, but it would be 
at a higher risk of misbehaviour.


I second the view that the other fans will likely notice once the CPU 
fan is quietened.


Gordon.

I do this when writing software or processing data sets. Let a fast remote

Yep, the 3GHz P4 is basically a small electric fire, by modern standards. 
However, there are heatsink and fan combos that are reasonably quiet. Look for 
big heatsinks and big fans, run at low RPM.

Any particular reason for Core2Duo and not i5/i7 or phenom/bulldozer?

That one looks interesting. There are some other (more monolithic) blocks with 
larger fans.

The reason for looking to large diameter fans is to move the same amount of 
air with much reduced noise. There are some very detailed explanations of why 
this happens on the web, if you are particulary interested in this aspect

wouldn't got for a E6750 slap up a bit of extra cash and go for a Q6600 granted 
these processors are a few years old but they still run anything you throw at 
them. Or I would go for the i5 2500k, which essentially is the successor to the

Re: [Hampshire] Quiet and cool PC running?

2012-05-01 Thread Imran Chaudhry
Thin client idea - funny you should say that because I do have the
ingredients already to do that! But for me doing development would become
a bit of chore because of having to await two machines to boot up instead
of one. Also the wife would not tolerate another server in my data centre
(aka behind the living room sofa) so I would be back to square one with
respects to noise.

To answer some other questions - I never buy current generation hardware to
be honest and I like to grab a bargain where I can. I think I could get a
used Gigabyte-brand mobo + good C2D + 4GB for around £60. I think that
would be fine for my purposes for a few years. I never play games, strictly
productivity stuff and web-browsing really. As long as the system can
*quietly* run Debian Squeeze with Gnome 2 (and eventually Ubuntu 12.04 with
Unity 3D) in 1900x1200 (my GPU is a GeForce 8400GS PCI-e) with my usual
session: several gnome-terminals, Chrome with ~10 tabs open, Clemantine
playing music in the background, gedit, XChat and usual LAMP services such
as MySQL, Apache2, modperl etc then I will be very happy. Phew - listing
all that makes me think I should go for quad-core :-)

The P4 actually exposes 2 logical cores (via Hyper-threading I think) to
the OS and normally the load keeps low - however YouTube, Picasa and other
stuff seems to push the loadav to 3 or 4+ very easily. Thats when the
temperature rises and the fan noise kicks in.

  Teradici defined standards for KVM over IP (with a zero client on your
 desk)
  a while ago, and we have been using the Dell variant of the kit (FX100)
 for
  quite a while at work. It's very good stuff, but I wouldn't use it at
 home due
  to the price!

 I was thinking more along the lines of VNC, or X over ssh on a 1gig local
 LAN.
