WELL HOWDY GUYS! Long time no spcr!
My god chylld youve been upto alot since ive been away, SWEET looking box! Im gonna go head over to that link after ive replied to this.
Well alot to answer too...
IMO get the eheim 1048, the 1250 will cause minor earthquakes so stay away from that. The 1048 is very quiet if decoupled properly, mine isnt decoupled/suspended and is just resting on some foam, from just over 1m it is inaudible. I have a friend with a 1250 and he elastically suspended it in his spare 5 1/2" bays, that surprisingly works VERY well hes not into silencing as much as i am. A word of advice, only watercool your cpu as watercooling other parts of your computer is unnecessary and if you do, other things will suffer such as temperatures and your ability to silence as effectively. The 1048 is plentily sufficient to cool very high performance + overclocked cpus QUIETLY (*ahem* me *ahem*)
From other peoples experiences and reviews ive read apparently the Hydor L30 is slightly quieter than the eheim 1048 but its flow is slightly lower (i dont know how much significance this would have on temps - depends on waterblock).
Oh yeah as were on the subject of waterblocks, dont get a high pressure waterblock as these are for:
A.) Hardcore overclockers wanting every last degree C they can and...
B.) People with powerful waterpumps (... yeah noisy ones!

)
er what else is there...
*scrolls up*
oh yeah the point about
[quote=chylld]firstly, if you're doing it for noise, then you're going to be disappointed. a finely tuned aircooled setup will, in my experience, be quieter than even a finely tuned watercooled setup. however, the watercooled setup will perform 10 degrees or more better, and that's where the advantage of watercooling is. [/quote]
erm i'd kinda have to disagree with that... chylld is very correct when he says the watercooled setup will perform XX degrees or more better... BUT i disagree when he says its not going to be quieter as you see... I had about a 15 deg C temperature drop when i originally switched to watercooling but instead of just having that 15 deg C temperature drops and a *kinda* quiet computer, i took that temperature drop and used it to my advantage by lowering the voltages to my radiator+case fans, THUS raising my cpu temps slightly BUT on the OTHER hand making my system FURTHER quieter. (I hope you all got that). The resulting, erm, result, is that i have temps that are around 8-9 deg better than a quiet air setup AND i have a quieter setup than a quiet air setup. So ive effectively balanced my system for the best of both worlds, silence AND good cooling.
in my system i used to have a heavily overclocked juhib 1700+ at xp3000+ speeds running 100% load 24/7 (folding) my temp stayed around 49 deg C or less and this is with all my fans including my 120mm radiator fan on 5V! and were talking a super crappy cheap 120mm fan too. on the upgrade list is a papst fan i should be able to run that at around 4-4.5V with similar temps and even more silence... not that i can hear my other fan...
chyllds advice is otherwise sound, and id agree with it all totally.
do not think of getting a watercooling radiator at all. everything from blackice wont give you good temperatures with anything less than a 120mm fan on 12V which is what were trying to avoid as the objective is a quiet computer. DEFINATELY get a heatercore like chylld says its the best and not only that its cheaper than a radiator.
if you browse other peoples watercooling setup that are hardcore silencers or overclockers you'll notice one thing, people RARELY use radiators, think about it

i wasted alot of money buying a radiator and regretted it.
reserviours: not needed but they can be handy, they look cool too. I personally dont use one because i dont have the space, im sure youve seen a pic of my setup, i crammed all my stuff into my little BQE.
tubing: yeah dont get anything less than 1/2" silicon is the standard but i tried clearflex (almost identical to tygon but cheaper) not too long ago and its alot better (alot more expensive too) - always buy more than you think you need because you'll need it! Its upto you what you choose, dont get standard tube though because rather than you deciding the layout of your watercooling system, your pipes will decide that for you and its always for the worse! they have a mind of their own!
oh yeah and about the push/pull thing, its been discussed alot by watercooling enthusiasts about which is better/worse, i noticed chylld reccomended a pull setup... i run a push setup just fine, its upto you really try them both, whichever works better for you will be fine. Ive tried both ways and i dont get any temperature difference at all, i just run a push because it works easier with my limited space...
er i think thats all for now, ive typed way too much and its late now. off to chylld's post!!!
