ideas on fan replacement

[HypERSoniC]

if anyone has any ideas on how we can replace the ps2 fan with a newer, quieter one, post them here.

sofar i know:

* the stock ps2 fan is too noisy
* it is a 60mm fan

Hehe i've got the same problem, although the new v9 is quieter, does it use the same fan at a lower voltage or is it a different fan?

Seems to be operating at 7v too.. hmm

I've been using this one for about a year now in my V4. It's never overheated even after 8-9 hour sessions of Prince of Persia and is nearly silent. I've run it 2-4 hour sessions with the harddrive for about a month now. Still no probs.

The way I understand it the fan line has an inline regulator that runs nominal at 7v and ramps up to a max 12v when the NA/HDD is in use.

Does anyone know of fnas with leds on them that can fit the PS2?

Here is a very quiet fan that should fit the ps2:

In reference to this fan you've listed. I'd hazzard to guess that the CFM is too low on it. I don't know because I haven't used it but it 9 cfm at 7v it would be around 5 cfm. Also 20mm is probably too thick to fit the enclosure from what I know. Could be wrong though. The one I listed is almost 17 CFM and at 7v it would be around 9 CFM. I still have to put my ear right next to it to be sure it's working at that speed.

As far as LED's go. It's difficult to find 60x15 fans with leds. You'd probably be better off just to add them yourself. Make sure there's a proper value resistor inline with the led for long life. If you put them on the fan + then they would increase in brightness as the fan voltage ramps up. Just a thought anyway.

I was also thinking about moding my fan on my PS2.. I think it would be interesting to put a LED or LED's inline with the fan.. However.. Homegrown-do you know what resistor you would need to run just one LED to the fan?..
I would think it would be tuff to get a resister that would work sents the PS2 "Ramps up" the voltage back and forth...

[homegrown]

Nah, it wouldn't be that hard. I used to run my fan at 12v straight off the PSU and I can tell you the inline fan voltage rarely (if ever) reaches 12v. Probably more like 7-10v and only for brief periods will it hit 10v. Like the first 1 or 2 minute you turn it on. Just use ohms law to determine a resistor value in that comfort zone.

V=IR

so for example

For a 12v supply voltage @ 20mA the required resistor would be:

10volts (PSU)/.02amps(LED) = 500ohms(RESISTOR)

(10volts because most LEDs have a 2volt voltage drop. Blue and white leds are 3.5 - 4 volts)

I did some blues inline off a 12 volt PSU last year and I think the resistors were somewhere around 140ohms (can't really remember it's been awhile) and they worked fine. Just get SMC resistors off of whatever old junk board you got laying around a solder to the leg of the LED

So if you calculate on the low value (7v) they'll get a bit brighter @10v

do regular 60mm fans slide into the fan socket of the power switch bracket?

[homegrown]

No, I've got 2mm foam tape on the sides in bottom to hold it in place.

lol, man I havent used ohms law sents I was in high school.. Time to brush up on the basics agian I guess... Thanx for your replie homegrown...
Plus thanx for sayin that most LEDs have 2V drop.. I didnt know that..
Another thing (not to sound stuped) but was does SMC resisters mean?..
I just thought a resister was a resister but with diff. resistece specs..
Ive havent heard of a SMC resister before..

Man Im dum Just me now.. lol
