Hi! :D

Ever since I bought this computer some three years ago I have tried to make it quiet. I started my “journey” with Enermax fans, AX-7 CPU cooler, another Antec case with stock PSU (loud). Then I updated it with a Fortron PSU, much better, Papst fans (all fans wired up with Zalman Fanmates), Zalman GPU-cooler and Novibes hard drive mounting (still in use, as you can se below).

But …

… It wasn’t quiet enough, and the Papst were ticking - utterly annoying. So after consulting SPCR, I decided to start over with an Antec SLK3000B case. Compared to my old Antec, it’s very plastic! First impression wasn’t very good, what had I done?? :lol: But after some extensive modding, I’m quite pleased with it 8) I also ordered two Nexus Realsilent 120mm (case fans), Nexus 92mm (CPU fan) and Thermalright SI-97 heatpipe cooler (a real mess to install, imo!) and the new Nexus 9003 power supply.

You can take a look at my current hardware setup in my signature. Yes it’s old (3 years in May) but for what I do – writing news for a Swedish HW website/chatting/web design, it’s sufficient. My next computer will almost certainly be a Mac so I don’t feel any need to upgrade this one, although maybe I buy a used 9800 Pro or something to improve my FPS in GT Legends (one of the very few games I play).

So what have I done to make it silent? Well, let’s go through my computer using some pictures:

Image

Overview of my case, you can see that I’ve cut the fan grill and used rubber mountings for the Nexus fan (corner cutting the Nexus wasn’t very fun at all actually).

Image

A little bit closer. Here you can see the CPU fan, Zalman heat pipe and my not so very nice cable management. The intake Nexus fan is mounted using ordinary screws. Also visible in this picture are all the Acoustipac damping material I’ve stuffed the case with.

Image

This picture reveals my motherboard, NF7-S. The horrible NB-fan is replaced by the classic golden passive Zalman chipset cooler. On the left side I’ve mounted a Fanmate connected to my CPU fan. The black cable with the blue diod is a temp sensor used by the PSU to decide when to start the case fans.

Image

A better view of the backside of the computer … Note that I have replaced the screws with thumbscrews. One could also spot the orange Nexus fan inside the 9003 PSU.

Image

A lot of Acoustipac here … note the golden and not the black stock screws for the CPU fan duct.

Image

Here is why! I installed a dust filter which required me to change the screws. I’ve tried covering as many small holes as possible to prevent dust to enter the case.

Image

Even more Acoustipac! Made wonders for the door’s otherwise very plastic feeling.

Image

Note the ghetto method used to cover the air intake at the bottom.

Comments are appreciated. Except for HDD whining I'm happy ...

Very nice !!
I did something quite similar with my old SLK 2600 AMB : damping, cut the fan grills.

Eventually gave up trying to cut the HD noise and swapped to a 2" 1/2 HD. Got dead silent rigth away.

With that front bottom intake closed off, it seems to me like there's a massive imbalance between the intake area and the exhaust area. Maybe you could try removing some of the PCI slot backplanes and see if that improves airflow?

That hole in the side looks rather small to me, and it's filtered.

What sort of temps you get??

I have the same board, chipset cooler, and CPU HS (SI-97), and on my NF7-S v2.0 I get around 50c loaded on my 3200+ stock at low-mid 80s ambient. I have the Zalman 92mm fan @ 5.5v~ with the resistor that came with it.

Hi!

I have done something similar.
thermaltake sonic tower with 120mm glacialtech fan on 1000 RPM. Another Glacialtech as an intake same RPM, and default tri speed 120mm on lowest RPM on outlet. The noise is very small, but you can hear it. Is it possible to reduce it totally? Hard drives are on rubber dampers and I cannot hear them on idle. Temperatures are:

Motherboard 46 °C (115 °F)
CPU 45 °C (113 °F)
Maxtor 6Y080L0 29 °C (84 °F)
Seagate ST3120827AS 30 °C (86 °F)

only slitly higher on full CPU load.
Funny is that MBO temperature is constantly higher then CPU :-)
It could be due to plenty of cables through case that disturb the airflow.
I wanna know if someone of you had experience with "fanless" coolers and are these temperatures ok?

(don't know how to put picture here :-)

Ciao and keep it cool (and quiet :-)!!
