Rads 120.3?

Thermochill PA 120.3 or TFC 120.3 - from what I've read the PA was very slightly better at very low fan speed, and the TFC radiators level at slightly higher rpm fan speed (800rpm ish?). Can't remember where I saw the comparison though, and numbers may be slightly off. They're quite thick radiators.
 
cheers looking at Scythe Slip Stream 500rpm 120 mm which are meant to be 24.5cfm and 7db
Pretty much identical to the noctua 800rpm modded to 500rpm but half price.
 
The newer XSPC RX360 is supposed to be a match for those two mentioned above rads too. Especially at low fan speeds.

that'll change tho, once they finalise & release the PA-140.3, presuming you've got a case big enough to accomodate the thing in the first place.
 
I bought an XPSC rad recently for a build, i took the opportunity to try it in my own rig first (cpu+gpu loop) replacing my existing feser.

I was very impressed with the XPSC RX360 rad, there was certainly no discernable difference in temperature between the two rads (perhaps 1-2c if that, i didn't notice any change at all).

That was using 1000rpm sharkoon fans. If the RX360 had come out sooner, i'd have saved the money and gone for that over the feser any day.
 
lets face it other companys have caught up with thermochill now (thats why they are releasing the 140 RADs)
The main thing to remeber when buying a RAD some work better in push than pull, high or low fan speeds so choose one for the application you want.

yeah but who makes silent 140 fans. It's like cases with 140 fans I don't see the point until companies get on the 140 bandwagon.

well I'm after one for 500rpm in push+pull mode.

500rpm is very slow. Even in push pull you may need 2 360 rads if you hope to maintain this speed. It's unlikely but you may may get away with using some thicker 38mm fans.

I ended up using the slow, quiet Nexus fans. Iirc they are Yate Loons by anther name. They are also cheap as chips. At 900rpm you are more likely to hear the sound of the air across the rad fins than you are any noise these fans make. A possible exception is pwm noise but that's down to your controller.

Edit: PA120.3 btw. Sometimes two in the summer :)

Planning 2 or 4.
1 for each component. Just depends If I want to make the case huge for triple sli/x-fire.
Silent is more imprortant than over clocking, but still planning on a bit of overclocking.
Not buying yet, I just need to make sure when I build teh case I get all the holes in the correct place.

Excellent plan :D

Now the problem may be finding fans that can run as slow as 500rpm ;)
 

:D:D

You appear to have things well sorted. If it were me I'd double check their suitability for use with rads, push pull should help but some case fans are only good for blowing into open space. I would also pick a fan that did 500rpm at 7v, or whatever convenient minimum voltage you're targeting, but went up to XXX rmp at 12v. It gives you a lot more flexibility not just for over clocking but also for summer/winter ambient temps.

Anyway, I look forward to seeing the final result :D

How would I find out if teh fans are suitable?

It's going to be a while probably be couple of months for the case and then a year or so for the components. Although I will be sticking my old system in there, in the mean time.

Here's teh case thread
http://forums.overclockers.co.uk/showthread.php?t=17971098

Although I think I'm going to change the position of the rads to the side panel and make the case wider but shorter and lower.
As the case is going to sit on the desk with the side panel facing forward. As I'm fed up of not having any leg room with case and printer on the floor.

Find a more specialist forum and ask around. I like xtremesystems but it may be Monday before it's back up and running.


Full case build, nice if a little ambitious for me. Tall and skinny, I approve :D

You may like this idea. My latest project, two PA120.3s + six fans in a space less than 200mm X 230mm. I've no idea how well it will work :eek:. Free for personal use of course.

Intresting Idea ecat - I guess all the fans are either pushing air into the void (out the rads) or sucking air out of it (in through the rads).
Looks like a 'boxer' engine block :D

Try a V6 next (with just the three top fans)

Thank you. Going off topic:

Following the current trends in product naming I call it the 200wPA.3TriFanx2 ;)

All fans pulling in my case.

The basic version has a flat central baffle plate to avoid the problem of a fan or fans pulling air straight through the opposite fans.

If I get adventurous the active version uses 'Advanced Microprocessor Control', aka a £3 pic to dynamically balance the fan speeds, oh yes :D

Perhaps the most interesting option is to use a profiled central baffle, something like this :

... seal the ends, add some fittings and presto you have a combined reservoir :D There may even be room for a DDC :D:D.
