    其實koolance都出過好多問題,唔知點解冇人點提過
    (例如QDC都試過漏水,要成批回收,QC問題其實間間都有架啦)
    唔係好建議用Koolance RP-452X2 Dual 5.25in Reservoir
    咩原因自己睇啦,我唔多講喇:

    140mm 好既風扇好難搵,如果用係gtx 更加難,厚排轉數要求要再高D,
    140mm fan係高轉數下嘈音唔野少架所以小弟都係用420rad轉用12cm fan,效果更好更靜
    如果14cm 最勁風壓應該都係e把13葉鋁風扇:
    不過嘈得驚人,要靜的話有WING14 OR Noiseblocker

    其實我又覺得唔洗"斬腳指避沙蟲"
   小弟用EK 5.25" bay 水箱同水樽,不過都係一體過冇膠水位,
    唔係幫EK賣廣告,只係我用左半年都暫時冇問題
    大吉利是講句,可能遲D我o個隻都會出事都唔定架

That is the installation orientation when using  the stock pump top.

Any res using glue as a seal has higher risk of leaking, that is why it's not recommended, nothing to do with QC.  Koolance no-spill QDCs are still the beset though.  As for Koolance products in general, I wouldn't recommend Koolance prior to 2008, but they have improved a lot since then.

BTW, this what the Koolance rep said about orientation of the pump being upside down:

Laing's literature mentions to avoid upside-down pumps, but we've been doing this for 6 years (PC4, RP-1000, ERM-3K4U5, RP-980/1005/985/401X2). I think it's to help avoid cavitation because they're not self-priming. I would guess that friction on the ceramic impeller bearing is actually less when inverted. Regardless of the reasoning, we've never had an issue running pumps this way as long as they're burped when filling.

Tim

According to Oliver Laing, the inverted orientation is not recommended to avoid issues with air. If you burp the pump before running it, there shouldn't be any problem. We haven't encountered any difference in pump failure between our products with upright pumps versus upside-down, even after tens of thousands of pumps. For performance, our RP-401X2 was designed for two inverted DDC pumps, which Martin listed as his "highest performing Koolance top tested to date".

I understand having air bubbles going through a pump until bled is extremely annoying, but individual systems vary in bleeding requirements and installation technique. There are alternative ways to avoid air going through a component if it's proving more difficult, including placing a fill port elsewhere in the system. It's no comfort to those experiencing problems, but the vast majority of RP-452X2 users are getting their Rev.1.0-1.3 units to bleed.

    可唔可以掉轉裝,遲D應該會知
    不過說明書咁講,始終都有條刺,
    不竟1隻D5都成7百,隻水箱要成千。
    如果成千蚊個水箱有機會整壞隻D5,真係唔敢試

    QDC只係比喻而已
    我只係對Koolance隻新水箱隻D5咁裝法有所保留
    漏水問題完全唔擔心,因為個構做同係密封。

I know.  That is why I said the case with XPSC res having a higher chance of  leaking has nothing to do with QC.  It's simply bad to use glue in reservoirs.   Koolance's  QDC leaking problem was due to a bad batch.

BTW, the issue with EK nickel plated blocks last year has nothing to do with bad QC either.  The problem was that they tried to save money by adopting a cheap plating process.  They now use the much expensive electroless plating.
