Zalman ZM80HP + ZM300A-APF?
How do I know how quiet (that is how little airflow I can have)
power supply I can use If I use a passive GPU cooler along with a low-airflow Papst 8412NGL (12db) CPU fan?
I'm running an Athlon XP 2000+ with an Alpha PAL8045T heatsink equipped with the 12 db Papst fan.
On my GF4 Ti4200 i use the passive
Zalman ZM80HP* heatsink and I if I lay my flat hand on the side of my case, I can feel it's apx. 30 degrees celsius - just the case that is.
The power supply fan seems to need to work a whole lot to get all the heat out of the case.
So - if I get the obviously very quiet (=lower airflow) ZM300A-APF power supp, how do I know it's pulling enough air out of my case?

hmm so u're relying totally on your PSU fan for your case ventilation?
I had that problem with my AOpen PSU, I ripped out the loud stock fan and stuck a Panaflow L1A onto it, but the computer would randomly reboot at intervals so I had to move up to a M1A. If u're getting a quiet PSU like the Zalman u've mentioned here it will have a thermal fan control (correct me if I'm wrong here guys) on it so the hotter the thermistor gets the faster that fan will spin. So if you're computer runs stable and u're not getting any weird reboots and stuff u should be okay with something like the Zalman

Yeah, I'm relying totally on my PSU for ventilation - less fans, less audible, right?
And yep, the Zalman PSU has a temperature controlled fan but I still don't know whether it -even at max- can move enough air to keep the case cool enough, strangely enough these figures doesn't appear either on Zalmans pages nor on the pages of the manufacturers of my current case/PSU, though I've sent them both an e-mail about it, but no answer so far.
So if anyone knows these figures - please tell me!

I would like to know as well, I sent an inquiry about my aopen psu fan/airflow several weeks ago. Actually come to think of it, it's probably been longer than two months now, and I still haven't gotten an answer!
I just kept getting juggled around by someone who didn't know and would forward it to the technicians, who then decided to forget about my message and bury it somewhere, in the deep bowels of the aopen mail system?
So... I wouldn't count on getting a good answer (or any for that matter) from them... or maybe I'm just being cynical... oh well, cross your fingers!

what PSU u got Reddawn?, I found that it took AGES for me to find the specs of my AOpen PSU on their website had to dig through some .DOC file that had the specs onto it. I found that the easiest way to get the spec for it is to pull the fan out and have a look at the sticker and then stick into google and see what it pulls up
Got it!
D80BH-12 12V, 2900 RPM (Ball Bearing), 33 CFM, 35dB (yuck!).
I replaced it quite a while ago now though, I inserted a AVC fan undervolted to 5V, but that's soon to be replaced as well, it's also too noisy.
At the time I replaced the fan I didn't know about such things as thermistors in the PSU changing the volt output to the fan, and consequently I cut the wire from the fan almost exactly at the point where it made entry (were soldered) to a tiny PCB, mounted by a screw to one of the heatsinks. I also cut up a small hole in my grill to let the 3-pin powerconnector slip through.
At least I've learned something, next time I'll connect my fan to the original cable, to allow variable voltages according to PSU temps to be delivered to the fan.

doh!, what I did with my AOpen (powerman) mod was to cut the wire with a little bit of extra clearance to work it, when I swapped my 2nd new fan into the setup (the 1st one didn't have enuff airflow panaflow L1A) I put a 3 pin connector onto the end of the wires with the 3rd RPM pin pulled out so as not to cause any sparking and now if I want to do further changes to my fan in my PSU all I need to is to unscrew the fan and pull it straight out no more soldering
Nice solution, I'll think I'll do that instead next time.
Good thing you mentioned it, because I probably wouldn't have come to think about it otherwise!
Also, a general question: Is it 'easy' to replace the heatsinks on any given PSU, or is that a major no-no, and I'd be better off forgetting I ever thought about it?

here's one much simpler mod as well, just put copper plates where the heatsinks were and a copper pipe running water through it and the zero fan zone article http://www.zerofanzone.co.uk/content.as ... 50w&page=1 tell us how it goes

After thinking about this a little, I've decided I won't do anything stupid until I actually know exactly what I'm doing. :p
I'm not particularly familiar with handling of electronics, cutting cables, reconnecting them, doing modifications etc.
So until I gain that knowledge, I'll try and sit tight, planning what I will do when I know how to.
I am thinking of taking some sort of basic electronics course at university - or elsewhere (if such a thing exists), so I could get to learn the basics at least.
I have no idea where else to turn, since I don't have any friends/relatives/acquaintances that has any knowledge about these things.

I guess... still, I'd like to have somewhere to turn if I botch something.
I'm usually extremely careful when working with things, and perhaps even more so when working with computers. What bugs me is that as soon as I don't have any precise knowledge of how to do something, I tend to avoid doing it alltogether, simply because previous experience has proven to me that if I don't know what I'm doing, I probably shouldn't be doing it. What does this all mean? Well... let's just say I've wrecked my fair share of things...
For the time being, I think I'll stick with the small stuff (like you say), and then later on, move on to bigger (and badder?) things. It is nice to dream though.

yeah though my theory is that u haven't REALLY twiddled with a computer till u've fried something, my tally so far is two toasted BX boards (the fan wire I hacked up the electrical tape slipped and was shorting to the case)
didn't find out till my new KT133A board just wouldn't boot up, it wouldn't start until I got rid of the short, don't u love modern mobo protection

Two motherboards here as well (amongst other things), but that was mostly due to carelessness... and the occasional lightningbolt right through the house.
First motherboard I managed to completely rip off the lever of the socket (nice one huh?), and the second was like I said before, lightning causing massive overvoltage, and a fried motherboard. Luckily, everything else turned out to be ok, the motherboard took the hit.
