Well,
I am not talking of people who are crazy abt. you.
I am talking of the number of fans you have installed
on your computer to keep its kool.

I have 5 in all
1 of processor..actually i don't need to mention it.
1 of the SMPS
1 fan bringing cool air from the bottom front of the cabinet
1 fan sucking out hot air out from the cabinet on the back top.
1 fan almost bang behind the CPU fan, that is it provides
air to the CPU fan from the outside, instead of from the inside.

All in all I was able to silence it after all these measures.
I had to take these measures after my first SMPS got burnt
due to over heat!!

Well, people what do u do to cool your system?
Don't say A/Cs
Here in India we have 'em only in posh offices.:mrgreen:

0 in my desktop:
watercooled powersupply
watercooled cpu
watercooled gpu
passive cooled chipsets

All provided by water with the Zalman Resorator (and the pump broke, now my pc doesn't make any noice now, the broken pump does, got to replace it :evil: )

Don't know about the laptop, it makes too much noice if you ask me :D

Edit: never gonna do the watersplash adventure again, costs way too much, better put the pc in another room...

On my previous setup I had 12 Fans. 8 pcs. 80mm and 4 120 mm. (watercooling)
My Athlon 64 OCed from 200 to 275 Mhz FSB. :p
All fans running low rpm for a very silent system.
My current setup has only 4 fans, and is much noisier, and warmer too.

But I'm tired of configuring cooling systems, maybe I'll do one again later.

10-

1 proc
1 Video card
2 power supply
2 92 mm exaust
1 120 mm exhaust
2 120 mm intakes
1 chipset fan (On a passive ASUS board.... hmm)

Well each of the laptops has one fan for the CPU but that's normal.
The desktop AKA The Hulk (it's a Matrix Green full tower case).
1 for CPU
1 for Chipset
1 for GPU
2 in the PSU
2 in the front sucking air in (one of them is cooling the HDD at the same time)
2 in the back blowing air out
1 in the side of the case to pull hot air away from PCI slots
Total: 10
Even with a fan controller to turn down the RPMs the thing sounds like a jet ready to take off :)

can a single power supply support all of them?
or wud it burnout?
I 've got one more place to install fans on my system.
But that wasn't where I wanted the fan..so had
to make a hole for a fan on the cabinet!!

Fans don't use very much power.
Most only use about 1 watt, above 2 watt they usually get real noisy.

Are all these people with small scale gas turbine cycles attaching fans to preset points or botching their own. Then again my PC has:

2 fans top and bottom
1 CPU fan
1 GPU fan
2 PSU fans

so thats 6 but that takes up all the mount points on my case.

My Linux machine is a PII with no CPU fan, but there is a fan on the power supply.

My Windows machine is an Athlon with 3 fans: 1 on the power supply, 1 on the CPU and one on the video card.

2 fans:

- 120mm case fan
- Zalman alcu-???? CPU heatsink/fan (AMD Sempron 64 3000).

Fanless PSU (well, mostly) - Antec Phantom 500.

Mostly they run on the lowest speed possible. Although I turn the cpu fan on full during anything processor intensive for a long time (meaning a whole weekend or something), e.g. trancoding etc, even though I ran cpuburn-in for 64 hours with no ill effects after first building it.

Also have one hard drive in a SilenX hard disk silencer thing and the other, a 40Gb IDE which I just use dor nightly backups of /home, is in sleep mode (hdparm -y [dev]) when not in use.

Very quiet, but the saying that the more you get into quiet computing the louder they become is too true, so I am thinking about getting a scythe ninja heatsink and running it fanless and swapping out the 120mm fan for quieter seasonic.

However, I may wait for the new Intel CPUs to come out and get a bit cheaper...

On my desktop I have 2 120mm fans, one in PSU and one in radiator. It's a combination of passive and water cooling.

On my laptop there's only one fan.

It's not the fans that make your system cooler, it's how you build it to get a good airflow in right places ;)

Very good point!

Adding fans improperly can actually reduce cooling. I was reading an interesting tech thread about this on another board a couple of weeks ago.

I pulled a large rear chassis fan from my new case on my main (XP) office machine as it not only had almost completely restricted intake as installed, but was extremely noisy and was actually working at cross-purposes with the adjacent power supply and CPU fans. It was a total waste.

I have found that in my own experiments that sometimes adding chassis fans, even properly, didn't make any difference in measurable CPU temperatures, though I have had to add a fan to cool the new Maxtor main HD in this office box as it runs remarkably hot (apparently a Maxtor trait).

I really want to run more quietly.

When I installed the HD fan this morning, I hot-silicone mounted it to the front HD fan mount on the chassis, after removing the highly-constricting and otherwise pointless stamped fan guard. The silicone mount not only gives a good seal, but provides a lot of vibration/noise damping. I then jacked up the case on rubber feet to give a little better air-intake gap under the front of the box as there wasn't adequate flow to the fan as designed (this case has terrible venting). Unfortunately, while very markedly improving airflow through the fan to the HD, this has produced a really nasty reflected and resonant fan racket, nearly doubling the overall perceived noise of the box. :(

I bought one of those enormous Zalman dry coolers (http://www.zalman.co.kr/images/product_img/cooler/7700_AlCu.jpg) to try to get the noise down. It will cool the CPU adequately even with the fan off, but there are still other fans making a racket -- particularly this new one for the HD...though it's doing a great job of cooling the Maxtor after my removing the I/O airflow restrictions on the fan. :-|

If you really want a cooler-running box, though, pull off the cover or main side panel.

Ugly, Lo-Tech, cheap...but it works. :-k

YOu must have something that actually blows air into the cabin..

erikpiper
July 26th, 2006, 05:02 PM
Actually, in some cases, (Normally when the case has a BAD airflow design..) it can actually help- just try it and check your temps. It CAN help withought an additional fan..


Actually, best place for a computer (Especially with a BOTTOM intake) is right over the AC vent.. lol

Removing side panel helps if the case has very bad airflow. But that also increases noise seriously.

Blowing air in to the case isn't very useful. Axial fans used in computers don't create much pressure. It's more effective to use fans up in the rearside to suck air out of the case. In most cases only reason to use a fan on front side is to provide some air flow for hard disks mounted to front of the case if the case is designed badly and rear fans won't create enough air flow where your disks are. For example if your case's whole front side is open, or if you have holes in the side panel for CPU or GPU cooling..

You also have to remember that there are more parts inside your computer that need cooling than you'd think. Not only CPU, GPU and hard diskd need cooling, but also the power cirquitry on your motherboard and both noth and south bridge need proper cooling too. You can of couse just mount a fan for every piece that need to be cooled but then you'll end with lots of noise.

For basic ATX case the most effective way is to use a fan up on the rearside or on top of the case to suck air out together with the PSU, and then seal the the rest of the case tight only leaving holes for air to flow into the case directly in front of you hard disks (most PSU's use thermal controlled fans and if all hot air flows through the PSU it will increase the fan speed and noise).

So the air will first cool your hard disks, then flow up the case cooling your graphics card, south bridge, north bridge, power cirquitry and CPU and then exits through rear fan and PSU. If you have high-end graphics card you could also remove covers from the lovest PCI slots to give your GPU more fresh air. Thois would slightly mess the airflow, but not as much as holes in the side panel.

July 26th, 2006, 06:48 PM
What? You'll have to speak up! I can't hear you over the noise . . .

let's see:
2 rear exhaust
2 front intake
1 side exhaust
1 top exhaust
2 PSU
1 on the video card
1 on the CPU heatsink

It's loud, but it stays cool.

have only got 2, one on the cpu one on the psu, both were installed wen i brought the computer so they can get loud. and my gpu etc are passively cooled,

im thinking of adding a front intake fan to help cool the hard drives down, but im currently out of work so i cannot afford to spend to much, anyone know were i can get cheap case fans ( 80mm )

Theres 5 in my Mac Pro, and its virtually silent, can barely hear a thing unless its using a CD at all (the included DVD drive is about twice as loud as the machine itself).

The laptops, my Macbook Pro is a lot quieter, has 2 fans as far as I'm aware, and its pretty darn quiet. The PC laptop is a bit noisier, has a couple of fans too, and it goes mental when under load, but otherwise its fine.

My desktop only has two, the PSU and the CPU. The CPU is a Zalman 5000 fan (cant remember exact model), and while its not perfectly silent, its way quieter than the one that was in before.

2 in front pulling in fresh air
2 at the back sucking out hot air
2 on 320GB harddrive cooler - very effective - brings the HDD temperature down with at least 10C)
1 on 120GB harddrive cooler
2 on top cooler in front extracting hot air -fits into 5.25" bay
2 on Powersupply
14 in total
Windows machine

I have given up to try to cool down my 3.0 GHz Prescott Socket 478 CPU - (idling at 50C and 67C at full load) before I will do watercooling will rather upgrade to a Core 2 duo - I have built a PC that runs at 23C when idling and about 33C at full load!

Agree with you there, I also "love" the fact that my Prescott sings almost all the time.:popcorn:

I have three fans, on directly on top of my CPU fan and the other facing perpendicular to the CPU and the fan on top, it sucks air in whereas the one on top of the CPU sucks air out.

Just for the records, my Prescott runs at a max of 68C and idles at 60C. Impressive isn't it?;)

October 27th, 2007, 04:54 AM
I have:

1 fan in the power supply
1 exhaust fan at the rear
1 fan on the cpu cooler
1 fan on the video card

That is four fans. However, the one on the video card runs at a very slow speed, so it is almost inaudible. The rear exhaust fan is also set to run at a slow speed.
And the CPU fan runs at a slow speed most of the time, only to go fast when I run programs which are extremely demanding on the hardware! When the system got overworked it would start slowing down!

I've got nine in all. The computer runs very cool. I guess you could say I'm a little adamant about it. I won't buy a computer case unless it has enough room for at least two 120mm fans for intake and exhaust. I've also put hepa filters on all my intake fans so I only have to clean the inside of my case once a year, but I do the filters every other week.

Power supply:
1 120mm internal intake (850rpm)
1 92mm exhaust (1420rpm)

CPU:
1 120mm (1138rpm)

GPU:
1 60mm (1410rpm)

Northbridge:
1 40mm (1878rpm)

Case:
2 120mm exhaust (1430rpm)
1 120mm intake (1500rpm)
1 92mm intake (1318rpm)

Hrm..I have 2 on my AMD 64 desktop box.

One on the PSU
One on the CPU.

I am seriously thinking of adding a case fan - the mountings are already there, and the motherboard has a plug point spare for it.

The Nvidia card just has a huge heatsink, and under any intensive OpenGL work, it forces the CPU fan to spin up rather fast, so yes, I think I need another fan.

All stock fans. Running at around 41C to 50C just desktop using, i'd like to see that number when compiling something :D HDD runs at a stable 39/40C. Had it running like this for 5 years, even running Windows XP (15 minute boot times FTW). Surprised its still running perfectly.

Edit: Went inside the case today to work out why there were some weird noises coming from it. Turns out i got it wrong:

1 PSU
1 CPU

That use to run at an average of 46C. Now with the case off its running at a steady 33C. Im sure it wouldnt have made much difference if i had an exhaust fan, but the eir was just sitting there after coming through the holes. I need to buy some fans!
