@j-mag: True, but for me the thing to undervolt fans is to make them really silent. I haven't seen any 38mm fan that has a good bearing/motor noise, compared to 25mm models.
Plus, you don't need any more air or static pressure on a PA.
Yeah SPCR people would freak out at a 5v Sanyo Denki. I don't know what kinda environments you guys have your RIG in but, my ambient noise level is easily louder than San Aces at 7v even...Quote:

I agree motor noise tends to be higher on 38mm fans, but they have more resistance to overcome than 25mm fans...Quote:

1 kelvin = 1 celcius. only diff is kelvin 0 = absolute 0.
you can guesstimate the diff youd get by looking at the loop Radical_53 used and working out if you have more heat (bigger delta) or less (lower) and accounting for how good your pump is.
actual proper calculation would require you to derive your loop c/w, and thats simply not doable because we dont have accurate enough data/modelling of everything in a loop.
Thanks for the info creidiki. That is helpful. I am going to be buying another rad soon and am trying to figure out what is the best way to go for what I can afford. It's hard to justify $115 + $20 for a shroud for a PA120.3 over $60 for a Black Ice GTS for only 4c or so. Money (limited quantity thereof) can sure be a pain.
@j-mag: Sure, internal mount adds some restriction to air, no doubt about that. But: A PA + shroud does not scale that much with fan rpm when externally mounted. So, as a conclusion, it doesn't need to much air to go through to perform well.
Now if you mount it internally, the only difference might be that you'd need to run your fans a little faster. But just a little ;) The YL I used for the test were running max at 9.5V, or 1200rpm. So there's still some performance in reserve to deal with added restriction from an internal mount.
Also, internal mounting would be much worse for most of the other rads, as they needed more air to perform all the way.
About hearing fans, I think the cause is that many European houses don't have AC, plus they have very thick and heavy walls. Some more noise doesn't matter in the summer, but all the other time of the year it's really painful.
@voigts: I used the system from my sig for the test, so you can try to find out where you think yours might be considering heat output.
Its a heck of a lot easyer than trying to justify a Storm over an Apogee for 1-2c...Quote:

Very valid point. Or in my case, a Storm over a good old MCW6002.Quote:

Block is easyer to replace (you dont have to remod your case) and you can find some good deals on storms if you keep an eye out on FS/Fleebay.
Rad/Pump are a better investment than blocks, generally :)
went to thermochills website and saw this:
"Biggest surprise to me was that a PA with the shroud was able to maintain a performance level at 600rpm that all other rads needed 1200rpm to get to. If it comes to low noise, nothing is even close to the PA at this time." - Radiical53 @ XtremeSystems
i guess when radiical53 speaks even the manufacturers listen!!!
ps: tell them i need a pa120.3 maybe they will give me one:D

That'd be because I work for the manufacturer... hence the big "ThermoChill" logo in my sig... :DQuote:

@jimmy: Well, for me it's nice to see that someone appreciates my work and does believe in the results. So for me, as I do appreciate their efforts to build such a strong rad, they earned the award for an outstanding product.
From the tests I did so far, it was the first time that one single product outperformed the rest of the competition so much. Like on a CPU block review, there were 3 awards given, as three blocks were too close together to choose a #1, even more as each of them was specialized in some way. On a GPU block review, 2 awards were given as again they were too close together and each of them had its special features.
But here, it was too obvious and too clear to leave me another choice :)
I am going to build another case soon so remoding is not an issue. Now I just have to decide between the Swiftech MCR or the Thermochill. I like my passive car rad but the size of it is kind of getting to be a pain.Quote:

Just listing some spec's from the test of the "new" generation of rads:
Size:
GTS______396 x 30 x 132 mm
Cooltek___402 x 34 x 130 mm
PA_______427 x 60 x 127 mm
Weight:
GTS______880 g
Cooltek___1.060 g
PA_______2.100 g
Can anybody see anything "fishy"?
The PA is by faaaaarrrr the largest rad in that test, which no one takes into consideration...
Is it no wonder that the PA is the better radiator then perfomance and flowwise?
If the Cooltek or GTS was at the same (over)size as the PA, don't you think it would get MUCH more run for it's money or even it would start getting into trouble?

No. What you'd get is an extremely restrictive radiator that would take ludicrously high static pressure/cfm to go anywhere.
Cooltek/MCR = 12fpi, BIX (high cfm rad) 12fpi and nearly as thick as PA. So basically, a Cooltek/MCR as thick as a PA = HE, BIX.
Lets not talk about the GT, at 30fpi it woudl be like a brick wall.
I'm not trying to be rude here, but please try to understand more about radiator design before making that kind of comment. Part of the weight of the PA is in the armature, because the fpi count is so low (thats what makes it so good at low cfm) that according to marci the rads were twistable.
Ofcourse you have to rethink the FPI and fin design if you made the Cooltek or GTS 50% thicker, but that is not the point here :)Quote:

Could you please explain further your statement below:

According to Hardwareluxxx the Cooltek is 34mm thick and the PA 60mm thick..

i built my first water cooling set-up without xtreme systems.....it did ok i guess , then i bought danger den parts and built a better 2 loop setup. now that i understand more (thanks:D ) i'm finally gonna build what i started out trying to do. and hopefully i'll get it all installed before my better half see's the bank statement..;)
it would seem that the choice of rad has always been the consumer's
hence the PA is far more expensive than others, hence also far better performer
its still freedom of choice to choose whats the best of the best rad...
your free to mount it anywhere in your case, be it on the floor of your case
since the only cards most used is a vid card and sound card...
or anywhere else with a little case modding of course.
