The Feser Company X-Changer Sneak Peek

post #1 of 14
Thread Starter 
FYI

I got an insider's scoop on the new X-changer, special thanks to Danger Den for letting me try out a prototype..

Turns out to have a really competetive PD result to the PA120.3. I'm tracking down a PA to finally test for a true side by side "Tested on the same test bed" with known barb comparison. I'll update you when that is done, but in the mean time here is the X-Changer...very nice!!

My site:
http://www.martinsliquidlab.com/Fese..._3-Review.html



Tested results:


Compared to "PUBLISHED" results. I will update this to a real PA120.3 test pretty soon, then it'll be a worthwhile comparison. Right now all I can give you is comparison to published and I have no idea what kind of barb was used.

I plan to test it with some nice EK G3/8" barbs which have a 10.1mm ID, it's possible the published results were tested with some oversized plastic 5/8" barbs or something...I don't know.:shrug:



I'll keep you posted on an update, I have a feeling it'll be an evey closer race at that point, but I won't know until I test one.

It'll be even more interesting to see how the copper tubes affect thermal performance.

What's the most common barb currently used on the PA's??

@ Martin - Just out of interest what sort of method are you thinking about using to test the thermal properties of the rads?

Ideally I could calculate c/w curves, but I'm pretty sure I just don't have what I need to get that accurate. You would really need an environmental chamber and something that can measure water deltas down to .001C similar to this sort of testing:

I'm not going to have that luxury, so I'm thinking of setting a couple of fairly defined heat values. Maybe 100 watts, 200 watts, 400 watts or something similar and then test with some specific fan scenarios like yate loon D12SL12s, then a mid range fan, then some 105cfm panaflos.

I can use my crystalfontz and Dallas probes to monitor up to 32 channels with a relative acuracy of .0625 or at least .1C, and then just track water to ambient delta averages over a large array of probes. I think that would provide a good relative bit of information...just perhaps not actual c/w curves.

wow martin, your quite ahead of the game, just found out about these rads the other day and here you are testing them . I'd really know how these stack up thermally against the GTX and PA series because it looks very similar (thicker) than the PA.

Anyway, very nice, looks like it's not very restrictive at all, wonder if it will still perform well then.

Aren't these a lot more expensive than thermochill?
post #7 of 14
Looks like a pretty good rad...Yeah just doing the heat loads at set known values, with multiple sets of various cfm fans is plenty good for what we need the info for, you know, were not building the things we just want to know what kind of delta we can get with it......Factor in the ambients and we'll have some good usable data....Looks like fun...

Thank you, Martinm210

Between you and ira-k my water cooling odyssey has been painless and hassle free (normal PITA aside).

I really appreciate your scientific method and the visual aids that you post.
