Hi, I was wondering if it would be possible to remove the power supply-fan.

The reason why I want to do this?
I want to use the computer as a webserver, but that fan is to noisy for me to let it run while i'm sleeping. (same room...)

This is the configuration of the computer:
intel celeron 366 with 64mb ram, isa nic (ne1000 compatible) and isa videocard (trend micro), no other cards. There is also a 10GB samsung harddisk, floppy, and 8X cdrom.
The computer runs linux, cdrom is only used to install linux, and can be removed, floppy is used to boot the computer.
the processor has a 12V +/-5600rpm fan.
it has a 220W power supply, the power connector for the monitor is not used (no monitor once booted).

Does a powersupply produce much heat or can the fan be removed if there is not to much power taken from it?

Are there any websites that are handling such questions?

Johan

I would think twice before removing the fan from the power supply. You will SIGNIFICANTLY DECREASE the life of the the power supply. If it is bothering you, maybe you can move it to a different location. Perhaps a closet?

i'm not sure about removing the power supply fan. The electronics inside can get a little warm without being cooled off. You may consider an alternative cooling methold like a different type of heat sink. I stumbled across a heat sink that is completely electrical. One side gets very cold. I wish i could provide you with more information, but i think you should research and just experiment.

yes, that's another thing. The constant heat can make the electronics have a shorter life. My fan on my comptuer got clobbered with dust and stopped and the computer worked ok, but the power supply got a little bit warm.

you could get a new power supply. very cheap prices at computer shows. or, you could put in a different one, which is quieter. or you could rewire the fan so that it gets less voltage, so that it runs slower. i have a web server in my room, and it's quiet enough for me to sleep. also i have another computer which runs 24/7 in my room. with that one, i got a power supply with the fan inside the case, they are much quieter. the power supply only cost $12. good luck!

DO NOT REMOVE THE POWER SUPPLY FAN
Why, you ask? We had a user bring in his computer two months ago. He said smoke started pouring from the back of the case and he panicked and yanked the plug. Upon inspection, it turned out his PS fan had failed and the PS had gotten so hot (he said he left it on all the time) that it started to smoke badly (and possibly burn, there were scorch marks, but we couldn't tell if there was actual fire). I would say this would be risky, especially if you sleep in the same room with it. you might not wake up ever again.

But that was probably a new power supply, the one I've got is as old as the processor, maybe even older, and as you probably also now, the old stuff doesn't get that warm as all the new stuff.

I heard someone saying that he removed the fan from a pentium 100, underclocked it to 75 and even removed the processor fan, so I guess that it can't create that much heat...

Listen to these guys man! You do not want to open the case of a power supply unless you know what you are doing. There are some major capacitors in there that can shock the crap out of you or even worse. You could also be in the works for a major fire if you disable the cooling features that are provided for a reason on your power supply.

Buy an Enermax power supply and just replace it. They are the best and the quietest running.

I guess I'll keep the fan and put the computer in the closet... maybe I can isolate it a bit against the noise, and if not, I'll kick it on the street ;-)

I would never risk removing the psu fan, for the reasons given above.
Try making sure the pc is placed in the best position such that any sounds eminating from it are not amplified.
For example if it is sitting on a wooden desk or shelf the sound can vibrate onwards. I have used longer rubber feet to overcome this, which lift up the pc and also assist cooling.
Do not place on soft material that might reduce the gap underneath as this can cause overheating.
Good luck - keep us posted.

Thanks for the idea. I'm going to replace the ps-fan and the cpu-fan to reduce noise. The case already has rubber feet. I think I'll also use something to isolate the closet against sound (leaving enough space for airflow).

do not remove it, replace it with a YS-TECH silent 80mm fan. these push plenty airflow for a PSU and are nice and quiet

oh yea... umm buy some akasa pax mate for around £15... you get enough for a midi tower and this should reduce the noise coming from your case significantly
