You think those will fit? I hope soo... But isn't there a bigger rubber thingy to cover the whole PSU? Cuz I fear that won't be enough lol

Those PSU silencer's work alright but won't lower the noise that much. If you're skilled enough you can always switch out the fans in the PSU.

why not hook up the fan controller than comes with the PSU, and turn the fans down.

I can tell you how to quite it if you'd like to know
[color=#800080]http://www.hardwareheaven.com/guides/psumod/[/color] replace the fans with some high CFM but quiet fans Use lower CFM's but then you need to sustailly increase the heatsinks mass and serfance area with out shorting or adding to much weight I also know how to mod a PSU to fanless but you'll need a very large heatsinks (about $20), some good hevey gague wire and some soldering iron skillz ..risky.. BTW: psu's carry large capistors that can do any thing from give you a nasty shock to stoping your heart! they hold a charge for 6mo to a year+! Be very very vareful..... AT your own risk

Enermax Noisetaker PSUs are excellent yet quiet PSUs. pick one up if you can afford it instead of trying to mod the one you already have.

I sleeved my PSU so no way am I selling it!
 I was thinking about changing the psu fans but I got no clue which ones! Some help? I can only buy stuff from this site www.ldlc.ch So outta all these, think any are good? http://www.ldlc.ch/cat/140059.html I was thinking about these  http://www.ldlc.ch/fiche/PB00016481.htmlI found out that the fans in my PSU push about 25CFM... Just in case! Thanks for your help people! You guys are really nice and supportive  I should donate once

It depends...
If the fans are temperature controlled, then adding some low noise case fans may reduce the demand on the PSU fans. On a temperature controlled PSU (one that really is controlled, as cheap makes plaster a "temperature controlled" sticker on anything with a cooling fan!), you are looking for the best CFM/noise, as the temperature control will lower the speed of a more powerful fan. On an uncontrolled fan, then you are looking to balanece the required (constant) airflow with the moise level, and a qieter but lower CFM fan is an option if not loading to maximum. NB. It appears the TT Purepower uses an 80x80x25 in one position, and an 80x80x15 in another - it may be sort of room for a 25 deep in the second position, as I can't see any other reason for not using two of the same, unles the intake fan is thinner to make it less powerful, so that the additional passive vents draw in as well |

Your right... One 25mm deep and the other 15...
http://www.ldlc.ch/fiche/PB00021095.html This is the only 15mm fan but it's for a VGA cooler... All I need to know wether this fan is usable or no  _____ |____| <------------- That is my PSU I have 2 fans... One here (in red) and one here (in blue) [color=Red]|[/color][color=Navy]___[/color]| (sry the top won't come like above... but anyways)  Which one do you guys think is the thinner one? I think the blue is thinner... CAn't open my PSU right now... Anybody know?

how about some pictures of that thing so i know what were looking at....
BTW: that sites collections of fans are pretty slim remember to look at th DB rateing, remember to look at the RPM also ball brearing fans last longer but they make more noise then bushless

I know the site doesn't have much choice but hell... Here is the OFFICIAL pics so check those out: http://www.thermaltake.com/purepower/W0026.htm
I'd rather get a fan at a fixed RPM so that the powersupply stays cold and even at higher working loads, stays nice... If the current fans only push 25CFM, then the antec red LED fans might be good (pushing far more) but a tad loud... Comments or suggestions from the site I showed? |

According to the specs, that PSU has temperature controlled fans - rather than altering the fans, if you have no case fans, than add a front intake in the fanbox that's normally provided, and a rear extract - if the PSU is the only fan in the case, then it will be working harder than it needs to.
The fans in the PSU will be connected to a temperature controlled source, so any replacements will be subject to the same control. LED Fans can be used with temperature control, but may not illuminate reliably unless there is a demand for close to full speed. |

Ya but what if I completely remove the temperature fans and replace em with a steady RPM fan... Then? I mean, I'll have the fan power connected to an exterior molex connector and everything should be fine... ?

your going to have to connect the fans to molex connecters then, not to the reostat in the power supply.

and the setup... tempature fans are self controled useally but have a seprate temp sensor wires... if it's that way *should* be ok wireing in constant rpm fansIf it has its own monitor chip (very very very boubt full) but not impossable then your stuck useing tempature controlled fans or wireing to the 12v line on the board right along with on one of the leads look for higher CFM fans then what shipped with it but quieter and you should be fine... you can go lower CFM if you increse the heat sink mass/suface area enough but thats tricky bussness it'd be best to open it and take a picture but... I remind you the moment you open a PSU the warrenty is gone... as allways all this is at your own risk

make sure your NOT grounded! unless you'd like to invite 600-2000+ volts running thew your body... My 400W has 3x 2000V capistors on th same line= 6,000 volts! more then a enough to severly shock you also more then enough to stop your heart.... try not to tuch the board or anything thats part of the circutry..... your fans, insulated wires are fine..... just what has to be.... a good precoution make sure your un grounded and I like to wear a hevey set of rubber kitchen gloves just in case.... I don't mean to try to scare you but you need to have a healty fear of whats in there, that keeps you carefull on on your toes. I've been in many PSU's..... I know some people who insanely tuched alot of the cirtuty in there and wer fine but it's high rish becouse of the huge capistors touch the wrng thing could ge you a nasty shock... the pictures should help alot............

Okay, neon I took the pics and will post em as soon as I get back home... But I got a major prob and well... I need ur advice. I opened my PSU (lost my warrenty) and well, took a few pics and put it back together and voilĂ*, one of the fans went DEAD
 Okay, I got freaked like hell and the other famm fans at home, just n to compensate with the heat went all the way to max on IDLE Well then, I turned off my PC and I have n 12cm fans so I started to have some fun and I've almost finished fitting the cm fan instead of 8 (will be helpful) but now I'm wondering, should I have it SUCK air in (from the CPU heatsink) or should I have it BLOW warm air onto the CPU heatsink?

As for cooling a two fanned PSU 1 fan should intake air, blowing over the psus heatsinks... and the other should expel the hot air out the back of your case as for the fan stopping make sure you didn't misasemble or get a wire or something in the fan keeping it from moveing or that you didn't pinch the /damage that fans wire..... or accendentally disconnected said wire.... to bad you don't live in the US i could have you just mail it to me  I've donePSU's so many times, its gotten rather easy..... For when you re wire the new fans in.... make sure you have some electrical tape handy but i suggest you pick up some liquid tape...

Neon... Finally some pics!!!
 The fan connections are soldered onto the the card thingy in there so yes, my 80x80x15mm fan is dead A better view  And here is what I HAVE done...  I need to calm that fan down... It's helpful (dropped about 3-5 degrees C from CPU and mobo but it's loud and I woudn't mind some control on it!!! )

Geeze man try resizeing those to say 40%
 But any ways it's a stadard 2 wire setup..... sould not be that hard to wire in new fans ok both fans are 80 MM right? FAN A , check and see if you've got enough clearence to put the fan outside the houseing,(clearence between PSU and you mobo / cpu heat sink etc), if so this will allow you to use any 80 mm fan.... just has to be mouted on the out side wich isn't hard FAN B, looks like it's easy to get out remove the 4 screws and slide it off to the left.. remeber you can flex the back outwards a little for clearence to help get the fan out... Example 1, one when you cut the wire cut it was close to the core of the fan as possable you want as much slack as you ca get for two reasons it's easier to work with and in case you screw up striping the wire..fans are polarised, red wire is positive black is negitive it will be the same on your replacement fans DO NOT TOUCH area's.... DON'T TOUCH THEM !!! The mosfet heasinks "shouldn't" be "hot" nor the fine edges of the circut board other then that ASSUME the rest will give you the shock of your life. It's better that way better safe then sorry.....BTW: the term "hot" means lives current (They may not be and you could test with a DVM but thats tedious and unessacart not to mention you could damage stuff if you didn't know wha you wer doing....) Your going to need to deside two things when adding / wireing your new fans.... To twist the wires togeather or to use a soldering iron an a bit of solder then you need to use an insulator like electrical tape.. but I highly reccomend you pick up some electrical liquid tape it's about $4 and well worth it... and then paint the exposed wire connections seprately to insulate them... you'll want good venilation becouse it stinks Look at my artical ASK any questions you have before you start! test the fans you plan to use before you start! for operation / noise level Make sure you have what you need on hand and it should only take some a few mintues... but take your bloody time! speaking of bloody watch for sharp edges in there! again the use of goves reccomended ALLWAYS HAVE SOMEONE NEAR BY JUST FOR SAFTY REASONS! It's kind like wear chafes while opeations a chain saw. You may never scew up but theres that odd accident were you would of berried that chainsaw in your leg with out it. The reason to have some one there is this shouldn't be done while your home alone if you were to get shocked / hurt you self etc.. and need medical attenion it's best to have someone near by to aid you... not trying to scare you but as I said when dealing with stuff like this you should take the beter safe then sorry path every time.... (As allways at your own risk, as in you break it or fry your self I'm not responceable )Oh and last but not least I useally test my work seprately before I install it in a case again.... I can try to tell you what to do but it isnt neccery just make sure you make sure both fans start when the PSU starts....

Okay well I tried to revive my tiny fan but no go so I cut it off and put electrical tape around it to isolate it. I have no space for a 80x80x25 fan so that was no go
Anyways, as you can see, I installed a 120mm fan instead on the outiside (looks very amateur) but hell! So fan A is gone. I have another fan and I'll take a pic so you can see!   So yes, it looks like a monster and I cut myself (no gloves lol) and it was tough but I had to do this. The problem is the sensor now in the PSU tells to FAN B to do almost nothing (spinning at 600rpm which IS SILENT but the new fan adds the noise the other one lost...) and so, the heat is dissapated everywhere in my case and not blown out!!! So I might try to replace fan B too but for the moment, I'd rather try to get some control on my new FAN A... What you advise Neon?

Insted of mounting the fan inside the PSU you put it on the outside and attach from the inside.... just reverse of how it was from the factory like this...  also when you isolated those wires you did so seprately right ?other wise it's shorted - not good Your new fan shoud be wired in to the PSU wireing

Yes they are seperated... And well isolated! My new fan is like the following:
 I have no grill on it yet but odering a fan filter plus a gril... I would have installed a 80mm fan but had none lying around except the 120mm fan... Is it really THAt bad having the 120mm instead of the 80mm? |

Ya the thing is that this new 120mm fan is almsost just as loud as the PSU running with both it's fans before... So I'm gonna get a Hardcano 12 I guess to control it... The only solution I got unless I buy a WHOLE new PSU (which I'm not doing).

Okay you know what Neon, I have come to the conclusion that my PSU is cursed
You know that my orange ball bearing fan didn't decrease noise at all? I said that it just added the noise I lost... Well I took that fan off and put a quite 18DBA fan with 44CFM but now the temp regulated fan in the PSU goes all the way to 3500 RPM (which was as loud as a jump jet harrier next to me  ) Oh well... My tough luck lol !
