It would appear that my "work" here is obviously done then.
You've admitted that the latest German/European production hardware will put yours to shame and reinforced that view by insisting we stick to stereotypically traditional components and not taking advantage of current offerings such as this particular manufacturer's kit for a start. Well, I hope Danger Den will bust out their cube rad in "the spirit of things" then.
German/Eu vs US was the spirit of this challenge, not low flow versus high flow. If you want a true low flow vs high flow contest, I suggest you look beyond cooling just the CPU and move with the times. Efficient multiple component cooling is one of the main advantages low flow watercooling has over high flow, air-cooling and even phase-change (and narrow bore low flow secondary watercooling is also the perfect companion to phase change for the ultimate in full system cooling).
An observation - What you guys don't see about WCP's choice of rad and pump is that on the whole, the system is probably more representative of the average restriction found in your typical end-user's system which consists of more than just one or two blocks. Here in Europe, at least, many people want to do away with all ancillary small diameter fans and yet retain the performance many crave.
As I understand it, GruntvillE are getting a replica of the WCP testbench so greater understanding of full system testing might be achieved at some point in the future. Perhaps they can even utilise the increased functionality of the BIX II's interchangeable fittings by testing blocks with both rad types fwiw.
Phaestus - a point of note; I said "Up the fans on the rad back to the GMLs "...
You are familiar with the Papst 4412 GML are you not? Hardly loud even at 12v at 32dB, regardless of the 7/12v adaptors.
This seems frankly pointless. Alphacool are happy to provide even the revised kit (which would probably have to be added to the existing range just to suit this particular test) but personally I think that yes, you may as well just test a block and we should save the kit test for a more open-minded site.
I'm not in the best of moods right now, what with my website designers way behind schedule, a court hearing tomorrow morning and having to finish three mod projects ready for the weekend's UK Modfest in London, (regardless of other commitments) so I'm unlikely to read all reponses or post back here till after the weekend. If a conclusion is reached as to what we are allowed to submit to this site for review in the meantime, please have a representative of Pro-Cooling contact me to give me the official position of the site itself on this.
Otherwise, seeing as the most vocal of you don't feel you can meet my initial transatlantic challenge without twisting it to suit your own ends, here's a purely low flow, narrow tubing based one for you -
I can cool every major heat producing component in my mid-tower PC with a fully internal setup using production, off-the-shelf, German parts with a 5 Watt pump and two low noise Papsts. Please show me a more efficient system using US production parts.
{The model of efficiency as I understand it is work in(wattage of pump and fans):work out (net heat dissipated)}.
That has always been an argument in favour of the low flow approach.
... and if you can't meet either challenge or have little to no experience of both approaches, then stop trashing products you have no experience of.
