I think it depends on the res itself. Just like my 自制大水塘水箱，since it is big enough, I filled the coolant level to "just" above the in take and out let location, no bubble formed.
(as you can see ...

ya thats ture,
if the res itself is well designed it shouldn't form extra bubbles into the loop.
Just like your tailor made res, the in-take and outlet is far apart to avoid sucking bubbles back into loop
and since the in/outlet align horizontally there is no pt to fill more fluid into the res.

also look at another useful interpretation by kkepic above #15, it means the same thing.
iirc, the Moderator here, Tony, also has practical experience on fluid mechanics.

Fluid mechanics is not my major, but in my opinion, a good res design (high flow with minimal bubbles/minimal energy wastage) is closely related to fluid mechanics. As far as I know, it is a topic difficult to ascertain the design result adequacy/efficiency simply by words or formula in advance, but only through practical test(s) on prototype or computer simulation can bear with a successful outcome......um....similar to fan blade design (effective airflow manipulation).

(as you can see from last little report of comparing 2 enzotach blocks.)
Actually, the made of this res is to easily set up loops in a very convenience way, and avoid the bubble problem!

sorry, allow me to clarify, bigger reservoir can not necessarily avoid bubbles, bubbles can also be restricted under small water volume (like the volume scale inside water blocks). Thats why I used the words 'form and shape' of the obstacle instead (physical surface/area factor), and it requires to compromise with its target content - liquid (water) coherence, power/flow and pressure factors (energy factor). Volume is not that much matter in this case.

楼主嘅問題, 開始玩水嗰時我都有, 分别係用ddc 18w, 同ek top連一體化水樽, 3分喉

loop 1 : ddc > 360排 > cpu > nb > 樽 = 1粒泡都冇
loop 2 : ddc > 140排 > display > 樽 = 打到水樽好似水滾咁, 每條喉都見到好多泡運行

初頭以為有地方收唔緊, 或有死位有氣, 搞咗幾個鐘..... 諗起先之前睇過同類型嘅個案,
結果加舊綿搞掂晒...

我只係玩過一套水冷, 經驗少, 都好想揾出問題所在.... 終合各位嘅討論...
我"暫時"會認為係水樽設計有關佔多

因為個樽去水位响呢度

我放綿嗰邊, 樽底係密封嘅, 唯一嘅去水位就比塊膠片分格開, D水到樽, 差不多係馬上就有
水流要即刻抽走, 好似 "hamsterspeed ching ' 講嘅一樣! 水力大猛, 打起有泡,但係又唔夠
時間往上排走... 已經又被抽走.... 死得

唔知我諗得啱唔啱呢? 又有冇更好嘅方法解决呢! 請指教吓

試下放舊綿係水面

而家放响樽下面, 係1粒泡都冇架........點解要放水面呢?(唔好睇wor!)  請指教吓

我都有放生化綿以解決氣泡問題，但想更清楚了解水流速度、水阻、水箱設計...等關係，故出帖討論。估唔到背後真係有咁多學問！
喱到D C Hing真係好勁！！！

我以前聽先水冷, 只會諗起... "會唔會漏水架!?"
呢喥係個好地方, 高手可以温故知新. 新手可以學到好多嘢 (我都係其中之一, 須然我整得唔太好 )
只要抱住討論, 觀摩嘅態度, D時間都會消磨得開心D啦
我都要再好好諗吓點搞好D倏水道先
各位c hing多多包函

睇黎我誤會左你個水樽ge設計
我個方法應該唔適用你個水樽

請問c hing用邊隻樽呀
