Watercooled Antec Truecontrol, voltage on the blocks.

ROFL. I will do that any nice layouts for the sticker?

I need to place my PSU adventure to a later date. I need to get my system up and running again, as I'm now using my son's computer, and he starts complaining

Idea's for the later date will be helpfull.

"There are better and safer ways to do that. ." (talking about psu silence)

I said:=

"I'd be very interested to know what they are because I wouldn't have gone to all the trouble with my PSU?"

Removing a fan and doing nothing else to the PSU, especially when the system has no other fans is definitely not better or in my mind safer, unless buying new PSU's is your favourite past time..

Fanless PSU's do exist but most, (are rubbish and), do not benefit from more intelligent design or concepts... just PSU's that have had their fans removed and are now rated lower. True fanless "high" wattage units have big sinks, (outside the unit sometimes), and still tend to run hot.

Silence sounds a very simple concept to get, but to make your PC sound exactly the same when its on as it does when it's off, and still keep it near top end performance wise is not easy at all..... Yes you can remove all the fans and have everything running so hot it almost cooks, but to truly solve it with silence takes a lot more work.

Granted I'm obsessed and I wouldn't expect you or anyone else to follow my religion, however to infer there is no point is simply missing the point . Effectively cooling a PSU so that it runs silently takes far more than just disconnecting the fan and crossing your fingers!

Oh and don't get me started on this mythical silent fan thing again.... it's a myth trust me

One thing stands: the only silent fan is a non spinning, non air moving fan.
All the rest will make sound vibrations.

The closest thing to that is the 2000 grid sandpapered fins of a 80mm airborne papst running at 5.5v without guard or anything obstructing it's airflow

This is a great forum! No flaming. A PSU with no airflow at all is not a good idea I agree. In my PC there are indeed fans although you would be hard pressed to hear them unless you kneel down next to it. Its not truly silent. Good luck to all.

[BladeRunner]

I agree and the two 12db "rated" pabsts I had wouldn't run, (start up), at 5v. they would at 7v although the airflow was pretty week, and they still made an annoying bearing sleeve / motor shaft variable sussshhing sound...not pleasant at all

Not to get too anal, (I know I often do), but we are talking extremes here, like fhorst I do believe the only truly Silent Fan is the one that's still disconnected and in its box

On the PSU you may want to read through my PSU build again. While I'd not deem to present it as an authority on the subject, (there seems to be mixed opinion on the mosfet wire extension part from some "experts") Some say its no issue if the wires are not too long & thick enough for the current loads, but one B&O engineer inferred.. DO NOT DO IT! it wont work!!... This was after it had been running water-cooled / fanless for about 1½ years ...... This is why I prefer being a modder to an engineer My build may not be the best way or the only way but it works for me with the Enermax PSU I used. It covers the live sink issue and my ways around it along with the update article that covers all the other things I found out along the way to have it running over two years cool & fanless...

I have worked on several PC lately that take a large slow spinning fan and baffle the air into a very small area. This works very well and makes very little noise – the draw back is that the computer has dust bunnies that multiply like the real thing. As many of the computer experts in here know dust is a very serious problems for PC, which is why I was working on them to begin with.

Bladerunner, Thanks for the feedback. I guess I've visitit your site about a hondred times I like your style!

Zero fan is not my goal, maximizing performence is. And a lot of the performence out there is limited due to the heat. When it gets to hot, the life span is half, and lockups are regular.

Like you've stated, it's amazing to see how a spot that does not get warm with only a little bit of airflow, will be hot in a situation with no airflow.

A PAPST will not start at 7v, but you can turn it down to 5.5 once spinning. Airflow will be more weak, but there is some airflow. After sandpapering the blades the sound went down.
A PAPST like that, in a closed case, is for me close enough to silent. The same goes for me for the 12cm PAPST
This is also the reason why I use 3 rads, to be able to get enough cooling at alomst silent airflow.

I don't have the soldering/milling skills (and believe me, I've tried!) to make it like yours or petter. It only ended me up in killing expensive PSU's

Oh well, Once I have my system up and running again, I'll thing of something

The site is very nice, i agree.

If all you want is maximizing performance, then watercooling your psu is not the way to go I believe. You will at best make the psu perform equally good with watercooling contra aircooling, I have not yet watercooled a psu with a noticeable reduction in performance though.
I do not really consider lifespan that much, at the pace hardware is replaced, the only hardware that dies in my hands is because of bad treatment. But I do not like my hardware hot either, not because of lifespan though.

About skills, I had trouble soldering in the beginning, but with practice it got better. I think that the timefactor is more important than the skills factor. The more time you put into the blocks, the nicer you can make them look and properly perform. The performance is properly more likely to lie in the design, but a good lapping and stuff will have something to say.
